BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km). Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications (page
426).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
Accelerate and slow down in a smooth,
moderate fashion.
Drive at steady speeds without
stopping.
Anticipate stops; slowing down may
eliminate the need to stop.
Combine errands and minimize
stop-and-go driving.
Close the windows for high-speed
driving.
Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
Keep the tires properly inflated and use
only the recommended size.
Use the recommended engine oil.
Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
Sudden accelerations or hard
accelerations.
Revving the engine before turning it off.
Idle for periods longer than one minute.
Warm up your vehicle on cold
mornings.
Use the air conditioner or front
defroster.
Use the speed control in hilly terrain.
Rest your foot on the brake pedal while
driving.
Drive a heavily loaded vehicle or tow a
trailer.
Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
Driving with the wheels out of
alignment.
Conditions
Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
Using fuel blended with alcohol may
lower fuel economy.
