The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper hasa2270
kg (5 000 lb.) trailer weight and 227 kg (500 lb.) tongue weight
capability.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer. Do not
drive faster than 72 km/h (45 mph) with any weight on the trailer while
towing on a hot day or in hilly country.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use D (Drive) or a lower gear when towing up or down steep hills.
This will eliminate excessive downshifting and upshifting for optimum
fuel economy and transmission cooling.
²Anticipate stops and brake gradually.
When descending long, steep downhill grades, always use a lower gear to
provide engine braking to save wear on brakes. Use Drive (Overdrive
OFF) on moderately steep hills, Second (2) on steep hills, and First (1)
on very steep hills.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to the Severe Duty Schedule in your
ªService Guideº for more information.

Trailer towing tips
²Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
If the rear axle is submerged in water, the rear axle lubricant should be
changed. Axle lubricant quantities are not to be checked unless a leak is
suspected.
FUEL CONSUMPTION
Fuel economy can be improved by avoiding:
²lack of regular, scheduled maintenance.
²excessive speed.
²rapid acceleration.
²extended idle.

TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ªService Guideº.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in theLubricant specificationssection in theCapacities and
specificationschapter.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not drive the vehicle if the fluid
level is below the COLD (C) area on
the dipstick and outside
temperatures are above 10ÉC (50ÉF)
(see figure to the right).
Your transmission does not use up fluid. However, it is recommended
that you check the transmission fluid at least twice a year. The fluid level
should be checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid should be checked at normal operating temperatures
66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal operating
temperature can be reached after approximately 32 km (20 miles) of
driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]) (see figure to the
right).
The transmission fluid should be in
this range if at room temperature
(10ÉC-35ÉC [50ÉF-95ÉF]) (see figure
to the right).
If your vehicle has been operated for an extended period at high speeds,
in city traffic during hot weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow the fluid to cool before
checking.
1. Park the vehicle on a level surface and engage the parking brake.
