STARTING AND OPERATING 177
(Continued)
Perform the maintenance listed in the Scheduled
Servicing
Ú page 293. When towing a trailer, never
exceed the GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
Do not drive more than 50 mph (80 km/h) when towing
while using a full-size spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
Check the trailer tires for proper tire inflation pressures
before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
For further information
Ú page 331.
Towing Requirements — Trailer Brakes
Do
not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
2,000 lb (907 kg).
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure or tires.
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in PARK
(P). For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL (N). Always, block or
"chock" the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch utilized
WARNING!
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping distance.
When towing, you should allow for additional space
between your vehicle and the vehicle in front of you.
Failure to do so could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
