Consider the following items when computing
the weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or
equipment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options or dealer-
installed options must be considered as part of
the total load on your vehicle. Refer to the “Tire
And Loading Information” placard for the
maximum combined weight of occupants and
cargo for your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the
Scheduled Servicing Ú page 322. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
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 colli-
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
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.
WARNING!
