116 STARTING AND OPERATING
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.

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 actuated 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 may be required for
any trailer, for example trailers in excess of
2,000 lb (907 kg). Trailer brake requirements
vary by local law, consult local legal require -
ments where the trailer is to be towed for trailer
brake requirements.

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. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. 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.
