Securing Child Restraints (With the Seat Belt in the Front Passenger Seat)

This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint 0 93.

In addition. the vehicle has a passenger sensing system which is designed to turn off the front outboard passenger frontal airbag under certain conditions. See Passenger Sensing System 0 81 and Passenger Airbag Status Indicator 0 136 for more information. including important safety information.

Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great if the airbag deploys.

{ Warning

A child in a rear-facing child restraint can be seriously injured or killed if the front outboard passenger frontal airbag inflates.

This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front outboard passenger frontal airbag inflates and the passenger seat is in a forward position.

Even if the passenger sensing system has turned off the front outboard passenger frontal airbag. no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance. even though it is turned off.

Storage

Caution

Loading cargo on the roof rack that weighs more than 100 kg (220 lb) or hangs over the rear or sides of the vehicle may damage the vehicle. Do not load cargo exceeding 100 kg (220 lbs) and always load cargo so that it rests evenly between the crossrails and does not block the vehicle lamps or windows. Fasten the cargo securely.

To prevent damage or loss of cargo when driving. check to make sure crossrails and cargo are securely fastened. Loading cargo on the roof rack will make the vehicle’s center of gravity higher. Avoid high speeds. sudden starts. sharp turns. sudden braking. or abrupt maneuvers. otherwise it may result in loss of control. If driving for a long distance. on rough roads. or at high speeds. occasionally stop the vehicle to make sure the cargo remains in its place.

Do not exceed the maximum vehicle capacity when loading the vehicle.

Fuel Gauge

Metric

English

When the ignition is on. the fuel gauge indicates about how much fuel is left in the tank.

There is an arrow near the fuel gauge pointing to the side of the vehicle the fuel door is on.

When the indicator nears empty. the low fuel light comes on. There still is a little fuel left. but the vehicle should be refueled soon.

Here are four things that some owners ask about. None of these show a problem with the fuel gauge:

At the service station. the fuel pump shuts off before the gauge reads full.

It takes a little more or less fuel to fill up than the gauge indicated. For example. the gauge may have indicated the tank was half full. but it actually took a little more or less than half the tank's capacity to fill the tank.

The gauge moves a little while turning a corner or speeding up.

The gauge takes a few seconds to stabilize after the ignition is turned on. and goes back to empty when the ignition is turned off.

Voltmeter Gauge

When the ignition is on. this gauge indicates the battery voltage.

When the engine is running. this gauge shows the condition of the charging system. The gauge can transition from a higher to lower or a lower to higher reading. This is normal. If the vehicle is operating outside the normal operating range. the charging system light comes on.

See Charging System Light 0 137 for more information. The voltmeter gauge may also read lower when in fuel economy mode. This is normal.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/15/19

Instruments and Controls

Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased. this condition should correct itself as higher engine speeds allow the charging system to create maximum power.

The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven. turn off all accessories. such as the radio and air conditioner.

Readings outside the normal operating range indicate a possible problem in the electrical system.

Universal Remote System Programming

If equipped. these buttons are in the overhead console.

This system can replace up to three remote control transmitters used to activate devices such as garage door openers. security systems. and home automation devices. These

Do not use the Universal Remote system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1. 1982.

Read these instructions completely before programming the Universal Remote system. It may help to have another person assist with the programming process.

Keep the original hand-held transmitter for use in other vehicles as well as for future programming.

Erase the programming when vehicle ownership is terminated.

See “Erasing Universal Remote System Buttons” later in this section.

To program a garage door opener. park outside directly in line with and facing the garage door opener receiver. Clear all people and objects near the garage door.

Make sure the hand-held transmitter has a new battery for quicker and more accurate transmission of the radio-frequency signal.

Programming the Universal Remote System

For questions or programming help. see www.homelink.com/gm or call 1-800-355-3515. For calls placed outside the U.S.A. Canada. or Puerto Rico. international rates will apply and may differ based on landline or mobile phone.

Programming involves time-sensitive actions. and may time out causing the procedure to be repeated.

To program up to three devices:

Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in) away from the Universal Remote system buttons with the indicator light in view. The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/15/19

Instruments and Controls

At the same time. press and hold both the hand-held transmitter button and one of the three Universal Remote system buttons to be used to operate the garage door. Do not release either button until the indicator light changes from a slow to a rapid flash. Then release both buttons.

Some garage door openers may require substitution of Step 2 with the procedure under “Radio Signals for Some Gate Operators” later in this section.

Press and hold the newly programmed Universal Remote system button for five seconds while watching the indicator light and garage door activation.

If the indicator light stays on continuously or the garage door moves when the button is pressed. then programming is complete.

There is no need to complete Steps 4–6.

If the indicator light does not come on or the garage door does not move. a second button press may be required. For a second time. press and hold the newly programmed button for five seconds. If the light stays on or the garage door moves. programming is complete.

If the indicator light blinks rapidly for two seconds. then changes to a solid light and the garage door does not move. continue with programming Steps 4–6.

Learn or Smart Button

After completing Steps 1–3. locate the Learn or Smart button inside the garage on the garage door opener receiver.

The name and color of the button may vary by manufacturer.

Press and release the Learn or Smart button. Step 6 must be completed within 30 seconds of pressing this button.

Inside the vehicle. press and hold the newly programmed Universal Remote system button for three seconds and then release it. If the garage door does not move or the lamp on the garage door opener receiver does not flash.

When the state of charge is high. the voltage is lowered slightly to prevent overcharging. The voltmeter gauge or the voltage display on the Driver Information Center (DIC). if equipped. may show the voltage moving up or down. This is normal.

If there is a problem. an alert will be displayed.

The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles.

This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.

A high electrical load occurs when several of the following are on. such as: headlamps. high beams. fog

EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs.

It can increase engine idle speed to generate more power. whenever needed. It can temporarily reduce the power demands of some accessories.

Normally. these actions occur in steps or levels. without being noticeable. In rare cases at the highest levels of corrective action. this action may be noticeable to the driver. If so. a DIC message might be displayed and it is recommended that the driver reduce the electrical loads as much as possible.

Driving and Operating

Control of a Vehicle

Braking. steering. and accelerating are important factors in helping to control a vehicle while driving.

Braking

Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.

Average driver reaction time is about three-quarters of a second. In that time. a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft). which could be a lot of distance in an emergency.

Helpful braking tips to keep in mind include:

Keep enough distance between you and the vehicle in front of you.

Avoid needless heavy braking.

Keep pace with traffic.

If the engine ever stops while the vehicle is being driven. brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops. there will be some power brake assist but it will be used when the brake is applied.

Once the power assist is used up. it can take longer to stop and the brake pedal will be harder to push.

Steering

Caution

To avoid damage to the steering system. do not drive over curbs. parking barriers. or similar objects at speeds greater than 3 km/h (1 mph). Use care when driving over other objects such as lane dividers and speed bumps.

Damage caused by misuse of the vehicle is not covered by the vehicle warranty.

Electric Power Steering

This vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required.

If power steering assist is lost due to a system malfunction. the vehicle can be steered. but may require increased effort.

See your dealer if there is a problem.

If the steering assist is used for an extended period of time while the vehicle is not moving. power assist may be reduced.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

If the steering wheel is turned until it reaches the end of its travel. and is held in that position for an extended period of time. power steering assist may be reduced.

Normal use of the power steering assist should return when the system cools down.

See your dealer if there is a problem.

Curve Tips

Take curves at a reasonable speed.

Reduce speed before entering a curve.

Maintain a reasonable steady speed through the curve.

Wait until the vehicle is out of the curve before accelerating gently into the straightaway.

Steering in Emergencies

There are some situations when steering around a problem may be more effective than braking.

Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand.

Antilock Brake System (ABS) allows steering while braking.

Off-Road Recovery

The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips:

Ease off the accelerator and then. if there is nothing in the way. steer the vehicle so that it straddles the edge of the pavement.

Turn the steering wheel about one-eighth of a turn. until the right front tire contacts the pavement edge.

Turn the steering wheel to go straight down the roadway.

Loss of Control

Skidding

There are three types of skids that correspond to the vehicle's three control systems:

Braking Skid — wheels are not rolling.

Steering or Cornering Skid — too much speed or steering in a curve causes tires to slip and lose cornering force.

Acceleration Skid — too much throttle causes the driving wheels to spin.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Defensive drivers avoid most skids by taking reasonable care suited to existing conditions. and by not overdriving those conditions. But skids are always possible.

If the vehicle starts to slide. follow these suggestions:

Ease your foot off the accelerator pedal and steer the way you want the vehicle to go.

The vehicle may straighten out.

Be ready for a second skid if it occurs.

Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water. snow. ice. gravel. or other material on the road. Learn to recognize warning clues — such as enough water. ice. or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.

Try to avoid sudden steering. acceleration. or braking. including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.

Remember: Antilock brakes help avoid only the braking skid.

Off-Road Driving

Four-wheel-drive vehicles can be used for off-road driving. Vehicles without four-wheel drive and vehicles not equipped with All Terrain (AT) or On-Off Road (OOR) tires must not be driven off-road except on a level. solid surface. For contact information about the original equipment tires. see the warranty manual.

One of the best ways for successful off-road driving is to control the speed.

{ Warning

When driving off-road. bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear seat belts.

Before Driving Off-Road

Have all necessary maintenance and service work completed.

Fuel the vehicle. fill fluid levels. and check inflation pressure in all tires. including the spare. if equipped.

Read all the information about four-wheel-drive vehicles in this manual.

Remove any underbody air deflector. if equipped. Re-attach the air deflector after off-road driving.

Know the local laws that apply to off-road driving.

Driving and Operating

To gain more ground clearance if needed. it may be necessary to remove the front fascia lower air dam. if equipped. However. driving without the air dam reduces fuel economy.

Caution

Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper airflow to the engine. Reattach the front fascia air dam after off-road driving.

Apply the brakes to stop the vehicle. and then apply the parking brake.

Shift into P (Park) and then restart the engine.

If driving uphill when the vehicle stalls. shift to R (Reverse). release the parking brake. and back straight down.

Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle. it is steep enough to cause it to roll over.

If you cannot make it up the hill. back straight down the hill.

Never back down a hill in N (Neutral) using only the brake. The vehicle can roll backward quickly and you could lose control.

If driving downhill when the vehicle stalls. shift to a lower gear. release the parking brake. and drive straight down the hill.

If the vehicle cannot be restarted after stalling. set the parking brake. shift into P (Park). and turn the vehicle off.

3.1.

Leave the vehicle and seek help.

3.2.

Stay clear of the path the vehicle would take if it rolled downhill.

Avoid turns that take the vehicle across the incline of the hill.

A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the

Driving and Operating

{ Warning

Getting out of the vehicle on the downhill side when stopped across an incline is dangerous.

If the vehicle rolls over. you could be crushed or killed. Always get out on the uphill side of the vehicle and stay well clear of the rollover path.

Driving in Mud. Sand. Snow. or Ice

Use a low gear when driving in mud — the deeper the mud. the lower the gear. Keep the vehicle moving to avoid getting stuck.

Traction changes when driving on sand. On loose sand. such as on beaches or sand dunes. the tires tend to sink into the sand. This affects steering. accelerating. and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers.

Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice. { Warning

Driving on frozen lakes. ponds. or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice; you and your passengers could drown. Drive your vehicle on safe surfaces only.

Driving in Water { Warning

Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water. it can still wash away the ground from under your tires. (Continued)

Warning (Continued)

Traction could be lost. and the vehicle could roll over. Do not drive through rushing water.

Caution

Do not drive through standing water if it is deep enough to cover the wheel hubs. axles. or exhaust pipe. Deep water can damage the axle and other vehicle parts.

If the standing water is not too deep. drive through it slowly. At faster speeds. water can get into the engine and cause it to stall. Stalling can occur if the exhaust pipe is under water. Do not turn off the ignition when driving through water.

If the exhaust pipe is under water. the engine will not start. When going through water. the brakes get wet and it may take longer to stop. See “Driving on Wet Roads” later in this section.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

After Off-Road Driving

Remove any brush or debris that has collected on the underbody or chassis. or under the hood. These accumulations can be a fire hazard.

After operation in mud or sand. have the brake linings cleaned and checked. These substances can cause glazing and uneven braking.

Check the body structure. driveline. steering. suspension. wheels. tires. and exhaust system for damage and check the fuel lines and cooling system for any leakage.

More frequent maintenance service is required. See the Maintenance Schedule 0 383.

Driving on Wet Roads

Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate.

Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water.

{ Warning

Wet brakes can cause crashes.

They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle.

After driving through a large puddle of water or a car/vehicle wash. lightly apply the brake pedal until the brakes work normally.

Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens. you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.

Hydroplaning

Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is

There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down. other wet weather driving tips include:

Allow extra following distance.

Pass with caution.

Keep windshield wiping equipment in good shape.

Keep the windshield washer fluid reservoir filled.

Have good tires with proper tread depth. See Tires 0 330.

Turn off cruise control.

Hill and Mountain Roads

Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include:

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Keep the vehicle serviced and in good shape.

Check all fluid levels and brakes. tires. cooling system. and transmission.

Shift to a lower gear when going down steep or long hills. { Warning

Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating. can reduce brake performance. and could result in a loss of braking.

Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.

{ Warning

Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and (Continued)

Warning (Continued)

Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line.

Be alert on top of hills; something could be in your lane (e.g. stalled car. crash).

Pay attention to special road signs (e.g. falling rocks area. winding roads. long grades. passing or no-passing zones) and take appropriate action.

Winter Driving

Driving on Snow or Ice

Snow or ice between the tires and the road creates less traction or grip. so drive carefully. Wet ice can occur at about 0 °C (32 °F) when

For Slippery Road Driving:

Accelerate gently. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick.

Turn on Traction Control. See Traction Control/Electronic Stability Control 0 229.

The Antilock Brake System (ABS) improves vehicle stability during hard stops. but the brakes should be applied sooner than when on dry pavement.

See Antilock Brake System (ABS) 0 227.

Allow greater following distance and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas.

The surface of a curve or an overpass can remain icy when the surrounding roads are clear.

Avoid sudden steering maneuvers and braking while on ice.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Turn off cruise control.

Blizzard Conditions

Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby.

If possible. use Roadside Assistance. See Roadside Assistance Program 0 404. To get help and keep everyone in the vehicle safe:

Turn on the hazard warning flashers.

Tie a red cloth to an outside mirror. { Warning

Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO). which cannot be seen or smelled. It can cause unconsciousness and even death. (Continued)

Warning (Continued)

If the vehicle is stuck in snow:

Clear snow from the base of the vehicle. especially any blocking the exhaust pipe.

Open a window about 5 cm (2 in) on the vehicle side that is away from the wind. to bring in fresh air.

Fully open the air outlets on or under the instrument panel.

Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.”

For more information about CO. see Engine Exhaust 0 215.

To save fuel. run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps.

If it takes time for help to arrive. when running the engine. push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps.

Do this as little as possible. to save fuel.

If the Vehicle Is Stuck

Slowly and cautiously spin the wheels to free the vehicle when stuck in sand. mud. ice. or snow.

See “Rocking the Vehicle to Get It Out” later in this section.

The Traction Control System (TCS) can often help to free a stuck vehicle. See Traction Control/ Electronic Stability Control 0 229.

If TCS cannot free the vehicle. see “Rocking the Vehicle to Get it Out” following.

“Steps for Determining Correct Load Limit–

1. Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s placard.

2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.

4. The resulting figure equals the available amount of cargo and luggage load capacity. For example. if the "XXX" amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle. the amount of available cargo and luggage

5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer. load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.”

See Trailer Towing 0 267 for important information on towing a trailer. towing safety rules. and trailering tips.

Turn the ignition off.

Leaving the Vehicle with the Engine Running { Warning

It can be dangerous to leave the vehicle with the engine running.

The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set.

If you have four-wheel drive and the transfer case is in N (Neutral). the vehicle will be free to roll. even if the shift lever is in (Continued)

Warning (Continued)

P (Park). So be sure the transfer case is in a drive gear – not in N (Neutral).

And. if you leave the vehicle with the engine running. it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running unless you have to.

If you have to leave the vehicle with the engine running. be sure the vehicle is in P (Park) and the parking brake is firmly set before you leave it. After you move the shift lever into P (Park). hold the regular brake pedal down. Then. see if you can move the shift lever away from P (Park) without first pulling it toward you. If you can. it means that the shift lever was not fully locked into P (Park).

Torque Lock

If you are parking on a hill and you do not shift the transmission into P (Park) properly. the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park).

This is called torque lock. To prevent torque lock. set the parking brake and then shift into P (Park) properly before you leave the driver seat.

When you are ready to drive. move the shift lever out of P (Park) before you release the parking brake.

If torque lock does occur. you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. You will then be able to pull the shift lever out of P (Park).

Driving and Operating

Shifting out of Park

This vehicle is equipped with an electronic shift lock release system.

The shift lock release system is designed to prevent movement of the shift lever out of P (Park). unless the ignition is on and the brake pedal is applied.

The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery.

If the vehicle has an uncharged battery or a battery with low voltage. try charging or jump starting the battery. See Jump Starting - North America 0 363.

To shift out of P (Park):

Apply the brake pedal.

Move the shift lever to the desired position.

If you still are unable to shift out of P (Park):

Ease the pressure on the shift lever.

While holding down the brake pedal. push the shift lever all the way into P (Park).

If you are still having a problem shifting. then have the vehicle serviced soon.

Parking over Things That Burn

{ Warning

Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers. leaves. dry grass. or other things that can burn.

Active Fuel Management

Vehicles with V8 engines may have Active Fuel Management. This system allows the engine to operate on either all or half of its cylinders. depending on the driving conditions.

When less power is required. such as cruising at a constant vehicle speed. the system will operate in the half cylinder mode. allowing the vehicle to achieve better fuel economy. When greater power demands are required. such as accelerating from a stop. passing. or merging onto a freeway. the system will maintain full-cylinder operation.

If the vehicle has an Active Fuel Management indicator. see Driver Information Center (DIC) (Base Level) 0 145 or Driver Information Center (DIC) (Uplevel) 0 147 for more information on using this display.

Extended Parking

It is best not to park with the vehicle running. If the vehicle is left running. be sure it will not move and there is adequate ventilation.

See Shifting Into Park 0 212 and Engine Exhaust 0 215.

There is an electronic shift lever position indicator within the instrument cluster. This display comes on when the ignition is on or in ACC/ACCESSORY.

There are several different positions for the shift lever.

See “Range Selection Mode” under Manual Mode 0 219.

P : This position locks the drive wheels. Use P (Park) when starting the engine because the vehicle cannot move easily. When parked on a hill. especially when the vehicle has a heavy load. you might notice an increase in the effort to

It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll.

Do not leave the vehicle when the engine is running. If you have left the engine running. the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move. even when you are on fairly level ground. always set the parking brake and move the shift lever to P (Park).

See Shifting Into Park 0 212 and Driving Characteristics and Towing Tips 0 262.

Driving and Operating

{ Warning

If you have four-wheel drive. the vehicle will be free to roll — even if the shift lever is in P (Park) — if the transfer case is in N (Neutral).

So. be sure the transfer case is in a drive gear. Two-Wheel Drive High or Four-Wheel Drive High or Four-Wheel Drive Low — not in N (Neutral). See Shifting Into Park 0 212.

R : Use this gear to back up.

Caution

Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped.

To rock the vehicle back and forth to get out of snow. ice. or sand without damaging the transmission. see If the Vehicle Is Stuck 0 198.

N : In this position. the engine does not connect with the wheels. To restart the engine when the vehicle is already moving. use N (Neutral) only. { Warning

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal. the vehicle could move very rapidly.

You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.

Caution

Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle.

Caution

A transmission hot message may display if the automatic transmission fluid is too hot.

Driving under this condition can damage the vehicle. Stop and idle the engine to cool the automatic transmission fluid. This message clears when the transmission fluid has cooled sufficiently.

D : This position is for normal driving. If more power is needed for passing. press the accelerator pedal down.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Use D (Drive) and Tow/Haul Mode when towing a trailer. carrying a heavy load. driving on steep hills. or driving off-road. Shift the transmission to a lower gear selection if the transmission shifts too often.

Downshifting the transmission in slippery road conditions could result in skidding. See “Skidding” under Loss of Control 0 190.

The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine. before making an upshift. if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed. throttle position. and vehicle load.

If the shift stabilization feature determines that a current vehicle speed cannot be maintained. the transmission does not upshift and instead holds the current gear.

In some cases. this could appear to be a delayed shift. however the transmission is operating normally.

The transmission uses adaptive shift controls. The adaptive shift control process continually compares key shift parameters to pre-programmed ideal shifts stored in the transmission’s computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used. such as with a heavy load or when the temperature changes. During this adaptive shift control process. shifting might feel different as the transmission determines the best settings.

When temperatures are very cold. the transmission's gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable with a cold transmission. This difference in shifting is normal.

L : This position allows selection of a range of gears appropriate for current driving conditions.

If equipped. see “Range Selection Mode” under Manual Mode 0 219.

Caution

Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission.

The repair will not be covered by the vehicle warranty. If the vehicle is stuck. do not spin the tires.

When stopping on a hill. use the brakes to hold the vehicle in place.

Normal Mode Grade Braking

This mode is enabled when the vehicle is started. but is not enabled in Range Selection Mode. It assists in maintaining desired vehicle speeds when driving on downhill grades by using the engine and transmission to slow the vehicle.

Kickdown Mode

The accelerator pedal provides an additional downshift after pressing through the kickdown feature.

It requires extra pedal pressure near the end of its travel to engage.

Manual Mode

Range Selection Mode

If equipped. Range Selection Mode helps control the vehicle's transmission and vehicle speed while driving downhill or towing a trailer by letting you select a desired range of gears.

To use this feature:

Move the shift lever to L (Manual Mode).

Press the plus/minus buttons on the shift lever to select the desired range of gears for current driving conditions.

Hold the plus/minus buttons on the shift lever to select the highest or lowest range available for the current vehicle speed.

When the shift lever is moved from D (Drive) to L (Manual Mode). a number displays next to the L. indicating the current transmission range.

This number is the highest gear that the transmission will command while operating in L (Manual Mode). All gears below that number are available. As driving conditions change. the transmission can automatically shift to lower gears.

For example. when 5 (Fifth) is selected. 1 (First) through 5 (Fifth) gears are automatically shifted by the transmission. but 6 (Sixth) cannot be used until the plus/minus button on the shift lever is used to change to the range.

When the shift lever is moved from D (Drive) to L (Manual Mode). a downshift may occur. The gear that the transmission is operating in when the shift lever is moved from D (Drive) to L (Manual Mode) determines if a downshift occurs.

Brakes

Antilock Brake System (ABS)

The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering while braking hard.

ABS performs a system check when the vehicle is first driven.

A momentary motor or clicking noise may be heard while this test is going on. and the brake pedal may move slightly. This is normal.

If there is a problem with ABS. this warning light stays on. See Antilock Brake System (ABS) Warning Light 0 140.

ABS does not change the time needed to get a foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead. there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room ahead to stop. even with ABS.

Using ABS

Do not pump the brakes. Just hold the brake pedal down firmly.

Hearing or feeling ABS operate is normal.

Braking in Emergencies

ABS allows steering and braking at the same time. In many emergencies. steering can help even more than braking.

Ride Control Systems

Traction Control/ Electronic Stability Control

System Operation

The vehicle has a Traction Control System (TCS) and StabiliTrak. an electronic stability control system.

These systems help limit wheel spin and assist the driver in maintaining control. especially on slippery road conditions.

TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens. TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin.

StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling.

StabiliTrak selectively applies braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the

If cruise control is being used and traction control or StabiliTrak begins to limit wheel spin. cruise control will disengage. Cruise control may be turned back on when road conditions allow.

Unnecessary Alerts

FCA may provide unnecessary alerts for turning vehicles. vehicles in other lanes. objects that are not vehicles. or shadows. These alerts are normal operation and the vehicle does not need service.

Cleaning the System

If the FCA system does not seem to operate properly. this may correct the issue:

Clean the outside of the windshield in front of the rearview mirror.

Clean the entire front of the vehicle.

Clean the headlamps.

For cleaning instructions. see “Washing the Vehicle” under Exterior Care 0 371.

System operation may also be limited under snow. heavy rain. or road spray conditions.

Automatic Emergency Braking (AEB)

If the vehicle has Forward Collision Alert (FCA). it also has AEB. which includes Intelligent Brake Assist (IBA). When the system detects a vehicle ahead in your path that is traveling in the same direction that you may be about to crash into. it can provide a boost to braking or automatically brake the vehicle. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation. the vehicle may automatically brake moderately or hard. This automatic emergency braking can only occur if a vehicle is detected. This is shown by the FCA

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

The system works when driving in a forward gear between 8 km/h (5 mph) and 80 km/h (50 mph). or on vehicles with Adaptive Cruise Control (ACC). above 4 km/h (2 mph). It can detect vehicles up to approximately 60 m (197 ft). { Warning

AEB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on AEB to brake the vehicle. AEB will not brake outside of its operating speed range and only responds to detected vehicles.

AEB may not:

Warning (Continued)

Detect all vehicles. especially vehicles with a trailer. tractors. muddy vehicles. etc.

Detect a vehicle when weather limits visibility. such as in fog. rain. or snow.

Detect a vehicle ahead if it is partially blocked by pedestrians or other objects.

Complete attention is always required while driving. and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes.

AEB may slow the vehicle to a complete stop to try to avoid a potential crash. The vehicle will only hold at a stop briefly. A firm press of the accelerator pedal will also release AEB.

{ Warning

AEB may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead. guardrails. signs. and other non-moving objects. To override AEB. firmly press the accelerator pedal. if it is safe to do so.

Intelligent Brake Assist (IBA)

IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead.

Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed.

IBA will automatically disengage only when the brake pedal is released.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

{ Warning

IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs. take your foot off the brake pedal and then apply the brakes as needed.

AEB and IBA can be disabled through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization 0 154. { Warning

Using AEB or IBA while towing a trailer could cause you to lose control of the vehicle and crash.

Turn the system to Alert. or if the vehicle has ACC to Off. when towing a trailer.

The AEB system does not need service.

Side Blind Zone Alert (SBZA)

If equipped. the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with moving vehicles in the side blind zone (or spot) areas.

When the vehicle is in a forward gear. the left or right side mirror display will light up if a moving vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side. the display will flash as an extra warning not to change lanes. Since this system is part of the Lane Change Alert (LCA) system. read the entire LCA section before using this feature.

Lane Change Alert (LCA)

If equipped. the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside mirror and will flash if the turn signal is on. { Warning

LCA does not alert the driver to vehicles outside of the system detection zones. pedestrians. bicyclists. or animals. It may not provide alerts when changing lanes under all driving conditions.

Failure to use proper care when changing lanes may result in injury. death. or vehicle damage.

Before making a lane change. always check mirrors. glance over your shoulder. and use the turn signals.

LCA Detection Zones

1. SBZA Detection Zone 2. LCA Detection Zone

The LCA sensor covers a zone of approximately one lane over from both sides of the vehicle. or 3.5 m (11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. The Side Blind Zone Alert (SBZA) warning area starts at approximately the middle of the vehicle and goes back 5 m (16 ft). Drivers are also warned of vehicles rapidly approaching from up to 70 m (230 ft) behind the vehicle.

How the System Works

The LCA symbol lights up in the outside mirrors when the system detects a moving vehicle in the next lane over that is in the side blind zone or rapidly approaching that zone from behind. A lit LCA symbol indicates it may be unsafe to change lanes. Before making a lane change. check the LCA display. check mirrors. glance over your shoulder. and use the turn signals.

Left Outside Mirror Display

Right Outside Mirror Display

When the vehicle is started. both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear. the left or right outside mirror display will light up if a moving vehicle is detected in the next lane over in that

LCA can be disabled. When you disable LCA. Side Blind Zone Alert is also disabled. See “Collision/ Detection Systems” under Vehicle Personalization 0 154. If LCA is disabled by the driver. the LCA mirror displays will not light up.

When the System Does Not Seem to Work Properly

The LCA system requires some driving for the system to calibrate to maximum performance. This calibration may occur more quickly if the vehicle is driving on a straight highway road with traffic and roadside objects (e.g. guardrails. barriers).

LCA displays may not come on when passing a vehicle quickly. for a stopped vehicle. or when towing a trailer. The LCA detection zones that extend back from the side of

Driving and Operating

LCA may not always alert the driver to vehicles in the next lane over. especially in wet conditions or when driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails. signs. trees. shrubs. and other non-moving objects. This is normal system operation; the vehicle does not need service.

LCA may not operate when the LCA sensors in the left or right corners of the rear bumper are covered with mud. dirt. snow. ice. or slush. or in heavy rainstorms. For cleaning instructions. see "Washing the Vehicle" under Exterior Care 0 371.

If the DIC still displays the system

If the LCA displays do not light up when moving vehicles are in the side blind zone or are rapidly approaching this zone and the system is clean. the system may need service. Take the vehicle to your dealer.

Warning (Continued)

If LKA only detects lane markings on one side of the road. it will only assist or provide an LDW alert when approaching the lane on the side where it has detected a lane marking. Even with LKA and LDW. you must steer the vehicle. Always keep your attention on the road and maintain proper vehicle position within the lane. or vehicle damage. injury. or death could occur. Always keep the windshield. headlamps. and camera sensors clean and in good repair. Do not use LKA in (Continued)

Warning (Continued)

{ Warning

Using LKA while towing a trailer or on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off.

How the System Works

LKA uses a camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings. It may provide brief steering assist if it detects an unintended lane departure. It may further provide an audible alert or driver seat may pulse indicating that a lane marking has been crossed.

To turn LKA on and off. press A to the left of the steering wheel.

If equipped. the indicator light on the button comes on when LKA is on and turns off when LKA is disabled.

When on. A is white. if equipped. indicating that the system is not ready to assist. A is green if LKA is ready to assist and alert if the vehicle crosses detected markings on one or both sides of the lane.

LKA may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking. A is amber when assisting. It may also provide a Lane Departure Warning (LDW) alert by flashing A amber if the vehicle crosses a detected lane marking. Additionally. there may be three beeps. or the driver seat may pulse three times. on the right or left. depending on the lane departure direction.

Driving and Operating

Take Steering

The LKA system does not continuously steer the vehicle.

If LKA does not detect active driver steering. an alert. chime. or DIC message may be provided. Steer the vehicle to dismiss. LKA may become temporarily unavailable after repeated take steering alerts.

When the System Does Not Seem to Work Properly

The system performance may be affected by:

Close vehicles ahead.

Sudden lighting changes. such as when driving through tunnels.

Banked roads.

Roads with poor lane markings. such as two-lane roads or in construction zones.

If the LKA system is not functioning properly when lane markings are clearly visible. cleaning the windshield may help.

A camera blocked message may display if the camera is blocked.

Some driver assistance systems may have reduced performance or not work at all. Cleaning the outside of the windshield behind the rearview mirror may correct the issue. The LKA system does not need service.

LKA assistance and/or LDW alerts may occur due to tar marks. shadows. cracks in the road. temporary or construction lane markings. or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LKA off if these conditions continue.

Driving with a Trailer

Trailering is different than just driving the vehicle by itself.

Trailering means changes in handling. acceleration. braking. durability. and fuel economy.

Successful. safe trailering takes correct equipment. and it has to be used properly.

The following information has many time-tested. important trailering tips and safety rules. Many of these are

When towing a trailer:

Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state.

State laws may require the use of extended side view mirrors.

Even if not required. you should install extended side view mirrors if your visibility is limited or restricted while towing.

Do not tow a trailer during the first 800 km (500 mi) of vehicle use to prevent damage to the engine. axle. or other parts.

It is recommended to perform the first oil change before heavy towing.

During the first 800 km (500 mi) of trailer towing. do not drive over 80 km/h (50 mph) and do not make starts at full throttle.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Vehicles can tow in D (Drive).

Tow/Haul Mode is recommended for heavier trailers. See Tow/ Haul Mode 0 221. If the transmission downshifts too often. a lower gear may be selected using Manual Mode.

See Manual Mode 0 219.

If equipped. the following driver assistance features should be turned off when towing a trailer:

Adaptive Cruise Control (ACC)

Super Cruise Control

Lane Keep Assist (LKA)

Park Assist

Automatic Parking Assist (APA)

Reverse Automatic Braking (RAB)

If equipped. the following driver assistance features should be turned to alert or off when towing a trailer:

Automatic Emergency Braking (AEB)

Intelligent Brake Assist (IBA)

Front Pedestrian Braking (FPB)

If equipped with Lane Change Alert (LCA). the LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer.

If equipped with Rear Cross Traffic Alert (RCTA). use caution while backing up when towing a trailer. as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. { Warning

When towing a trailer. exhaust gases may collect at the rear of the vehicle and enter if the liftgate. trunk/hatch. or rear-most window is open.

When towing a trailer: (Continued)

Warning (Continued)

Do not drive with the liftgate. trunk/hatch. or rear-most window open.

Fully open the air outlets on or under the instrument panel.

Also adjust the climate control system to a setting that brings in only outside air. See “Climate Control Systems” in the Index.

For more information about carbon monoxide. see Engine Exhaust 0 215.

Towing a trailer requires experience.

The combination of the vehicle and trailer is longer and not as responsive as the vehicle itself. Get used to the handling and braking of the combination by driving on a level road surface before driving on public roads.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

The trailer structure. the tires. and the brakes must be all be rated to carry the intended cargo.

Inadequate trailer equipment can cause the combination to operate in an unexpected or unsafe manner.

Before driving. inspect all trailer hitch parts and attachments. safety chains. electrical connectors. lamps. tires. and mirrors. See Towing Equipment 0 272. If the trailer has electric brakes. start the combination moving and then manually apply the trailer brake controller to check the trailer brakes work. During the trip. occasionally check that the cargo and trailer are secure and that the lamps and any trailer brakes are working.

Towing with a Stability Control System

When towing. the stability control system might be heard. The system reacts to vehicle movement caused by the trailer. which mainly occurs during cornering. This is normal when towing heavier trailers.

Following Distance

Stay at least twice as far behind the vehicle ahead as you would when driving without a trailer. This can help to avoid heavy braking and sudden turns.

Passing

More passing distance is needed when towing a trailer. The combination of the vehicle and trailer will not accelerate as quickly and is much longer than the vehicle alone. It is necessary to go much farther beyond the passed vehicle before returning to the lane. Pass on level roadways. Avoid passing on hills if possible.

Backing Up

Hold the bottom of the steering wheel with one hand. To move the trailer to the left. move that hand to the left. To move the trailer to the right. move that hand to the right.

Always back up slowly and. if possible. have someone guide you.

Making Turns

Caution

Turn more slowly and make wider arcs when towing a trailer to prevent damage to your vehicle.

Making very sharp turns could cause the trailer to contact the vehicle.

Make wider turns than normal when towing. so trailer will not go over soft shoulders. over curbs. or strike road signs. trees. or other objects.

Always signal turns well in advance.

Do not steer or brake suddenly.

Driving on Grades

Reduce speed and shift to a lower gear before starting down a long or steep downhill grade. If the transmission is not shifted down. the brakes may overheat and result in reduced braking efficiency.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

The vehicle can tow in D (Drive).

Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions.

When towing at higher altitudes. engine coolant will boil at a lower temperature than at lower altitudes.

If the engine is turned off immediately after towing at high altitude on steep uphill grades. the vehicle could show signs similar to engine overheating. To avoid this. let the engine run. preferably on level ground. with the transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on. see Engine Overheating 0 305.

Parking on Hills { Warning

To prevent serious injury or death. always park your vehicle and trailer on a level surface when possible.

When parking your vehicle and your trailer on a hill:

Press the brake pedal. but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill.

Have someone place chocks under the trailer wheels.

When the wheel chocks are in place. gradually release the brake pedal to allow the chocks to absorb the load of the trailer.

Reapply the brake pedal. Then apply the parking brake and shift into P (Park).

Release the brake pedal.

Leaving After Parking on a Hill

Apply and hold the brake pedal.

Start the engine.

Shift into a gear.

GVW includes the CURB WEIGHT of your vehicle. any passengers. cargo. equipment and the trailer tongue weight. Vehicle options. passengers. cargo. and equipment reduce the maximum allowable tongue weight the vehicle can carry. which also reduces the maximum allowable trailer weight.

Trailer Load Balance

The correct trailer load balance must be maintained to ensure trailer stability. Incorrect load balance is a leading cause of trailer sway.

The trailer tongue weight (1) should be 10–15% of the total loaded trailer weight (2). Some specific trailer types. such as boat trailers. fall outside of this range. Always refer to the trailer owner’s manual for the recommended trailer tongue weight for each trailer. Never exceed the maximum loads for your vehicle. hitch and trailer.

The trailer load balance percentage is calculated as: weight (1) divided by weight (2) times 100.

After loading the trailer. separately weigh the trailer and then the trailer tongue and calculate the trailer load balance percentage to see if the weights and distribution are appropriate for your vehicle. If the trailer weight is too high. it may be possible to transfer some of the cargo into your vehicle. If the trailer tongue weight is too high or too low. it may be possible to rearrange some of the cargo inside of the trailer.

Do not exceed the maximum allowable tongue weight for your vehicle. Use the shortest hitch extension available to position the hitch ball closer to your vehicle. This will help reduce the effect of the trailer tongue weight on the trailer hitch and the rear axle.

If a cargo carrier is used in the trailer hitch receiver. choose a carrier that positions the load as close to the vehicle as possible.

Combined Weight Rating (GCWR).

See “Maximum Trailer Weight” under Trailer Towing 0 267.

Tow/Haul Mode is most useful when towing a heavy trailer or carrying a large or heavy load: through rolling terrain in stop-and-go traffic in busy parking lots

Operating the vehicle in Tow/Haul Mode when lightly loaded or not towing will not cause damage; however. it is not recommended and may result in unpleasant engine and transmission driving characteristics and reduced fuel economy.

Integrated Trailer Brake Control System

The vehicle may have an Integrated Trailer Brake Control (ITBC) system for use with electric trailer brakes or most electric over hydraulic trailer brake systems. These instructions apply to both types of electric trailer brakes.

This symbol is on the Trailer Brake Control Panel on vehicles with an ITBC system. The power output to the trailer brakes is proportional to the amount of vehicle braking. This available power output to the trailer brakes can be adjusted to a wide range of trailering situations.

The ITBC system is integrated with the vehicle’s brake. anti-lock brake. and StabiliTrak systems. In trailering conditions that cause the vehicle’s anti-lock brake or StabiliTrak systems to activate. power sent to the trailer's brakes will be automatically adjusted to minimize trailer wheel lock-up. This does not imply that the trailer has StabiliTrak.

If the vehicle’s brake. anti-lock brake. or StabiliTrak systems are not functioning properly. the ITBC system may not function fully or at

Aftermarket Electronic Trailer Sway Control Devices

Some trailers may come equipped with an electronic device designed to reduce or control trailer sway.

Aftermarket equipment manufacturers also offer similar devices that connect to the wiring between the trailer and the vehicle.

These devices may interfere with the vehicle’s trailer brake systems or other systems. including integrated anti-sway systems. if equipped. Messages related to trailer connections or trailer brakes could appear on the DIC. The effects of these aftermarket devices on vehicle handling or trailer brake performance is not known. { Warning

Warning (Continued)

If the trailer brakes are not operating properly at any time. or if a DIC message indicates problems with the trailer connections or trailer brakes. carefully pull the vehicle over to the side of the road when traffic conditions allow.

Trailer Tires

Special Trailer (ST) tires differ from vehicle tires. Trailer tires are designed with stiff sidewalls to help prevent sway and to support heavy loads. These features can make it difficult to determine if the trailer tire pressures are low only based on a visual inspection.

Always check all trailer tire pressures before each trip when the tires are cool. Low trailer tire pressure is a leading cause of trailer tire blow-outs.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19

Driving and Operating

Trailer tires deteriorate over time.

The trailer tire sidewall will show the week and year the tire was manufactured. Many trailer tire manufacturers recommend replacing tires more than six years old.

Overloading is another leading cause of trailer tire blow-outs. Never load your trailer with more weight than the tires are designed to support. The load rating is located on the trailer tire sidewall.

Always know the maximum speed rating for the trailer tires before driving. This may be significantly lower than the vehicle tire speed rating. The speed rating may be on the trailer tire sidewall. If the speed rating is not shown. the default trailer tire speed rating is 105 km/h (65 mph).

Engine Oil

To ensure proper engine performance and long life. careful attention must be paid to engine oil.

Following these simple. but important steps will help protect your investment:

Use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.

Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.

Change the engine oil at the appropriate time. See Engine Oil Life System 0 295.

Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.

Checking Engine Oil

If equipped. the ENGINE OIL LOW ADD OIL message displays when the engine oil level may be too low.

Check the oil level before filling to the recommended level. If the oil is not low and this message remains on. see your dealer.

Check the engine oil level regularly. every 650 km (400 mi). especially prior to a long trip. The engine oil dipstick handle is a loop. See Engine Compartment Overview 0 288 for the location. { Warning

The engine oil dipstick handle may be hot; it could burn you.

Use a towel or glove to touch the dipstick handle.

Follow these guidelines:

To get an accurate reading. park the vehicle on level ground.

Check the engine oil level after the engine has been off for at least two hours. Checking the

Vehicle Care

When to Add Engine Oil

If the oil is below the cross-hatched area at the tip of the dipstick and the engine has been off for at least 15 minutes. add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” later in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity. see Capacities and Specifications 0 397.

Caution

Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If the oil level is above the operating range (i.e.. the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range). the engine could be damaged. Drain the excess oil or limit driving of the vehicle. and seek a service professional to remove the excess oil.

See Engine Compartment Overview 0 288 for the location of the engine oil fill cap.

Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.

Selecting the Right Engine Oil

Selecting the right engine oil depends on both the proper oil specification and viscosity grade.

See Recommended Fluids and Lubricants 0 392.

Specification

Use full synthetic engine oils that meet the dexos1 specification.

Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/15/19

Vehicle Care

Caution

Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty.

Viscosity Grade

Use SAE 0W-20 viscosity grade engine oil.

When selecting an oil of the appropriate viscosity grade. it is recommended to select an oil of the correct specification. See “Specification” earlier in this section.

Engine Oil Additives/Engine Oil Flushes

Do not add anything to the oil. The recommended oils meeting the dexos1 specification are all that is needed for good performance and engine protection.

Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.

What to Do with Used Oil

Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water. or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products.

Used oil can be a threat to the environment. If you change your own oil. be sure to drain all the oil from the filter before disposal. Never

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions. engine temperature. and miles driven.

Based on driving conditions. the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly. the system must be reset every time the oil is changed.

On some vehicles. when the system has calculated that oil life has been diminished. a CHANGE ENGINE OIL SOON message comes on to indicate that an oil change is necessary. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that. if driving

Cold Check Procedure

Use this procedure only as a reference to determine if the transmission has enough fluid to be operated safely until a hot check procedure can be made. The hot check procedure is the most accurate method to check the fluid level. Perform the hot check procedure at the first opportunity.

Use this cold check procedure to check fluid level when the transmission temperature is between 27 °C and 32 °C (80 °F and 90 °F).

Locate the transmission dipstick at the rear of the engine compartment. on the passenger side of the vehicle.

See Engine Compartment Overview 0 288.

Flip the handle up. then pull out the dipstick and wipe it with a clean rag or paper towel.

Install the dipstick by pushing it back in all the way; wait three seconds. and then pull it back out again.

Check both sides of the dipstick and read the lower level. Repeat the check procedure to verify the reading.

If the fluid level is below the COLD check band. add only enough fluid as necessary to bring the level into the COLD band. It does not take much fluid. generally less than 0.5 L (1 pt). Do not overfill.

Perform a hot check at the first opportunity after the transmission reaches a normal

If the fluid level is in the acceptable range. push the dipstick back in all the way. then flip the handle down to lock the dipstick in place.

Hot Check Procedure

Use this procedure to check the transmission fluid level when the transmission fluid temperature is between 71 °C and 93 °C (160 °F and 200 °F).

The hot check is the most accurate method to check the fluid level. The hot check should be performed at the first opportunity in order to verify the cold check. The fluid level rises as fluid temperature increases. so it is important to ensure the transmission temperature is within range.

Seat Belts

This section describes how to use seat belts properly. and some things not to do. { Warning

Do not let anyone ride where a seat belt cannot be worn properly.

In a crash. if you or your passenger(s) are not wearing seat belts. injuries can be much worse than if you are wearing seat belts. You can be seriously injured or killed by hitting things inside the vehicle harder or by being ejected from the vehicle. In addition. anyone who is not buckled up can strike other passengers in the vehicle.

It is extremely dangerous to ride in a cargo area. inside or outside of a vehicle. In a collision. passengers riding in these areas are more likely to be seriously injured or killed. Do not allow (Continued)

Warning (Continued)

Always wear a seat belt. and check that all passenger(s) are restrained properly too.

This vehicle has indicators as a reminder to buckle the seat belts.

See Seat Belt Reminders 0 135.

Why Seat Belts Work

When riding in a vehicle. you travel as fast as the vehicle does. If the vehicle stops suddenly. you keep going until something stops you.

It could be the windshield. the instrument panel. or the seat belts!

When you wear a seat belt. you and the vehicle slow down together.

There is more time to stop because you stop over a longer distance and. when worn properly. your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense.

Questions and Answers About Seat Belts

Q: Will I be trapped in the vehicle after a crash if I am wearing a seat belt?

A: You could be — whether you are wearing a seat belt or not. Your chance of being conscious during and after a crash. so you can unbuckle and get out. is much greater if you are belted.

Q: If my vehicle has airbags. why should I have to wear seat belts?

A: Airbags are supplemental systems only. They work with seat belts — not instead of them.

Whether or not an airbag is provided. all occupants still have to buckle up to get the most protection.

Also. in nearly all states and in all Canadian provinces. the law requires wearing seat belts.

How to Wear Seat Belts Properly

Follow these rules for everyone's protection.

There are additional things to know about seat belts and children. including smaller children and infants. If a child will be riding in the vehicle. see Older Children 0 87 or Infants and Young Children 0 89.

Review and follow the rules for children in addition to the following rules.

All vehicle airbags have the word AIRBAG on the trim or on an attached label near the deployment opening.

For frontal airbags. the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger.

For the front center airbag. the word AIRBAG is on the inboard side of the driver seatback.

For seat-mounted side impact airbags. the word AIRBAG is on the side of the seatback or side of the seat closest to the door.

For roof-rail airbags. the word AIRBAG is on the ceiling or trim.

Airbags are designed to supplement the protection provided by seat belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag. all airbags must inflate very quickly to do their job.

Here are the most important things to know about the airbag system:

Seats and Restraints

{ Warning

You can be severely injured or killed in a crash if you are not wearing your seat belt. even with airbags. Airbags are designed to work with seat belts. not replace them. Also. airbags are not designed to inflate in every crash.

In some crashes seat belts are the only restraint. See When Should an Airbag Inflate? 0 78.

Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the seat belts. Everyone in the vehicle should wear a seat belt properly. whether or not there is an airbag for that person.

{ Warning

Because airbags inflate with great force and faster than the blink of an eye. anyone who is up against. or very close to any airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to any airbag. as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt. even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor. (Continued)

Warning (Continued)

Occupants should not lean on or sleep against the front center armrest or console in vehicles with a front center airbag.

Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags.

{ Warning

Children who are up against. or very close to. any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how. see Older Children 0 87 or Infants and Young Children 0 89.

When Should an Airbag Inflate?

This vehicle is equipped with airbags. See Airbag System 0 74.

Airbags are designed to inflate if the impact exceeds the specific airbag system's deployment threshold.

Deployment thresholds are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. The vehicle has electronic sensors that help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle design.

Frontal airbags are designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries. mainly to the driver's or front outboard passenger's head and chest.

Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling.

It depends on what is hit. the direction of the impact. and how quickly the vehicle slows down.

Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle. and whether the object is fixed or moving. rigid or deformable. narrow or wide.

Frontal airbags are not intended to inflate during vehicle rollovers. rear impacts. or many side impacts.

In addition. the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity.

The vehicle also has a seat position sensor that enables the sensing system to monitor the position of the driver seat. The seat position sensor provides information that is used to adjust the deployment of the driver frontal airbag.

The front center airbag. if equipped. is designed to inflate in moderate to severe side crashes depending

Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact.

Seat-mounted side impact airbags are not designed to inflate in frontal impacts. near frontal impacts. rollovers. or rear impacts.

A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck.

Roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. In addition. these roof-rail airbags are designed to inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in

Seats and Restraints

In any particular crash. no one can say whether an airbag should have inflated simply because of the vehicle damage or the repair costs.

What Makes an Airbag Inflate?

In a deployment event. the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover. The inflator. the airbag. and related hardware are all part of the airbag module.

For airbag locations. see Where Are the Airbags? 0 76.

How Does an Airbag Restrain?

In moderate to severe frontal or near frontal collisions. even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions. even belted occupants can contact the inside of the vehicle.

Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant's body.

Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first. second. and third rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events. although no system can prevent all such ejections.

But airbags would not help in many types of collisions. primarily because the occupant's motion is not toward those airbags. See When Should an Airbag Inflate? 0 78.

Airbags should never be regarded as anything more than a supplement to seat belts.

What Will You See after an Airbag Inflates?

After frontal and seat-mounted side impact airbags inflate. they quickly deflate. so quickly that some people may not even realize the airbags inflated. The front center airbag and roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For location of the airbags. see Where Are the Airbags? 0 76.

The parts of the airbag that come into contact with you may be warm. but not too hot to touch. There may be some smoke and dust coming from the vents in the deflated

Seats and Restraints

When an airbag inflates. there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble.

To avoid this. everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates. then get fresh air by opening a window or a door.

If you experience breathing problems following an airbag deployment. you should seek medical attention.

The vehicle has a feature that may automatically unlock the doors. turn on the interior lamps and hazard warning flashers. and shut off the

A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle. such as the fuel system. brake and steering systems. etc. Even if the vehicle appears to be drivable after a moderate crash. there may be concealed damage that could make it difficult to safely operate the vehicle. (Continued)

Warning (Continued)

Use caution if you should attempt to restart the engine after a crash has occurred.

In many crashes severe enough to inflate the airbag. windshields are broken by vehicle deformation.

Additional windshield breakage may also occur from the front outboard passenger airbag.

Airbags are designed to inflate only once. After an airbag inflates. you will need some new parts for the airbag system.

If you do not get them. the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts.

The vehicle has a crash sensing and diagnostic module which records information after a

Even if the passenger sensing system has turned off the passenger frontal airbag. no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance. even though the airbag is turned off.

Never put a rear-facing child restraint in the front seat. even if the airbag is off. If securing a forward-facing child restraint in the front outboard passenger seat. always move the seat as far back as it will go. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available.

The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if:

The front outboard passenger seat is unoccupied.

The system determines an infant is present in a child restraint.

A front outboard passenger takes his/her weight off of the seat for a period of time.

There is a critical problem with the airbag system or the passenger sensing system.

When the passenger sensing system has turned off the front outboard passenger frontal airbag. the OFF indicator will light and stay lit as a reminder that the airbag is off. See Passenger Airbag Status Indicator 0 136.

The passenger sensing system is designed to turn on the front outboard passenger frontal airbag anytime the system senses that a person of adult size is sitting properly in the front outboard passenger seat.

When the passenger sensing system has allowed the airbag to be enabled. the ON indicator will light and stay lit as a reminder that the airbag is active.

For some children. including children in child restraints. and for very small adults. the passenger sensing system may or may not turn off the front outboard passenger frontal airbag. depending upon the person's seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a seat belt properly — whether or not there is an airbag for that person. { Warning

Seats and Restraints

If the Off Indicator Is Lit for an Adult-Sized Occupant

If a person of adult size is sitting in the front outboard passenger seat. but the OFF indicator is lit. it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged.

Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag:

Turn the vehicle off.

Remove any additional material from the seat. such as blankets. cushions. seat covers. seat heaters. or seat massagers.

Place the seatback in the fully upright position.

Have the person sit upright in the seat. centered on the seat cushion. with legs comfortably extended.

If the shoulder portion of the belt is pulled out all the way. the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens. unbuckle the belt. let the belt go back all the way. and then buckle the belt again without pulling the belt out all the way.

Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit.

{ Warning

If the front outboard passenger airbag is turned off for an adult-sized occupant. the airbag will not be able to inflate and help protect that person in a crash. resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat. if the passenger airbag OFF indicator is lit.

Additional Factors Affecting System Operation

Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking. which helps the passenger sensing system maintain the passenger airbag status. See “Seat Belts” and “Child Restraints” in the Index for additional information about the importance of proper restraint use.

Child Restraints

Older Children

Older children who have outgrown booster seats should wear the vehicle’s seat belts.

The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below:

Sit all the way back on the seat.

Do the knees bend at the seat edge? If yes. continue. If no. return to the booster seat.

Buckle the lap-shoulder belt.

Does the shoulder belt rest on the shoulder? If yes. continue.

If no. try using the rear seat belt comfort guide. if available. See “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 66.

If a comfort guide is not available. or if the shoulder belt still does not rest on the shoulder. then return to the booster seat.

Does the lap belt fit low and snug on the hips. touching the thighs? If yes. continue. If no. return to the booster seat.

Can proper seat belt fit be maintained for the length of the trip? If yes. continue. If no. return to the booster seat.

Seats and Restraints

If you have the choice. a child should sit in a position with a lap-shoulder belt and get the additional restraint a shoulder belt can provide.

Q: What is the proper way to wear seat belts?

A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips. just touching the top of the thighs.

This applies belt force to the child's pelvic bones in a crash.

It should never be worn over the abdomen. which could cause severe or even fatal internal injuries in a crash.

Also see “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 66.

According to accident statistics. children are safer when properly restrained in a rear seating position.

In a crash. children who are not buckled up can strike other people who are buckled up. or can be thrown out of the vehicle. Older children need to use seat belts properly. { Warning

Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash. they can be crushed together and seriously injured. A seat belt must be used by only one person at a time.

{ Warning

Never allow a child to wear the seat belt with the shoulder belt behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash. the child would not be restrained by the shoulder belt.

The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen. (Continued)

See the seat belt fit test in Older Children 0 87.

Securing an Add-On Child Restraint in the Vehicle { Warning

A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Secure the child restraint properly in the vehicle using the vehicle seat belt or LATCH system. following the instructions that came with that child restraint and the instructions in this manual.

To help reduce the chance of injury. the child restraint must be secured in the vehicle. Child restraints must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt. or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH System) 0 94 for more information.

Children can be endangered in a crash if the child restraint is not properly secured in the vehicle.

When securing an add-on child restraint. refer to the following:

Instruction labels provided on the child restraint

Instruction manual provided with the child restraint

Where to Put the Restraint

According to accident statistics. children and infants are safer when properly restrained in an appropriate child restraint secured in a rear seating position.

Whenever possible. children aged 12 and under should be secured in a rear seating position.

The vehicle may be equipped with a front center airbag in the inboard side of the driver seat. Even with a front center airbag. a child restraint can be installed in any second row seating position.

Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great if the airbag deploys. { Warning

A child in a rear-facing child restraint can be seriously injured or killed if the front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front passenger airbag inflates and the passenger seat is in a forward position. (Continued)

Warning (Continued)

Even if the passenger sensing system has turned off the front passenger frontal airbag. no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance. even though it is turned off.

Secure rear-facing child restraints in a rear seat. even if the airbag is off. If you secure a forward-facing child restraint in the front seat. always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat.
