Trailer towing table (4x4 and AWD with automatic
transmission)
Notes:For high altitude operation, reduce GCW by 2% per 300 meters
(1 000 ft) elevation. For definition of terms and instructions on
calculating your vehicle's load, refer toVehicle loadingin this chapter.
Maximum trailer weights shown. The combined weight of the
completed towing vehicle and the loaded trailer must not exceed the
GCWR.
Towing a trailer over 907 kg (2 000 lbs.) requires a weight distributing
hitch.
Do not exceed the GVWR
or the GAWR specified on
the Safety Compliance
Certification Label.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of control, and
personal injury.
Preparing to tow
Use the proper equipment for
towing a trailer, and make sure it
is properly attached to your
vehicle. See your dealer or a
reliable trailer dealer if you require
assistance.
Hitches
Do not use hitches that clamp onto
the vehicle bumper. Use a load
carrying hitch. You must distribute
the load in your trailer so that 10
Driving
129

to 15% of the total weight of the
trailer is on the tongue.
Use a frame-mounted weight
distributing hitch for trailers
over 907 kg (2 000 lb).
Safety chains
Always connect the trailer's safety
chains to the vehicle. To connect
the trailer's safety chains, cross the
chains under the trailer tongue and
allow slack for turning corners.
If you use a rental trailer, follow
the instructions that the rental
agency gives to you.
Trailer brakes
Electric brakes and manual,
automatic or surge-type brakes are
safe if installed properly and
adjusted to the manufacturer's
specifications. The trailer brakes
must meet local and Federal
regulations.
Do not connect a trailer's
hydraulic brake system
directly to your vehicle's brake
system. Your vehicle may not
have enough braking power and
your chances of having a
collision greatly increase.
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 19 mm (3/4 inch)
shank diameter. The bumper has a
1 590 kg (3 500 lb.) trailer weight
and 159 kg (350 lb.) tongue weight
capability.
Use a frame-mounted weight
distributing hitch for trailers over
1 590 kg (3 500 lb).
Driving while you tow
Do not drive faster than 88 km/h
(55 mph) when towing a trailer.
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.
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
Driving
132

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 checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Recreational towing (all wheels
on the ground)
Do not tow your vehicle with all
wheels on the ground as vehicle
damage may occur.
LUGGAGE RACK
Maximum load is 44 kg (100 lbs),
evenly distributed. If it is not
possible to distribute the load,
position it as far rearward as
possible. Adjustable tie down loops
(not equipped) must be used to
secure the load.

To adjust cross-bar position:
1. Slide the locking switches at
each end of the crossbar toward
the rear of the vehicle until
UNLOCKED appears.
2. Slide cross-bar to the desired
location.
3. Lock the cross-bar into position
by pushing the locking switches on
each end of the crossbar toward
the front of the vehicle.
The rear rack can be completely
removed in the UNLOCKED
position by sliding the cross-bar
rearward until it frees the guides.
FUEL CONSUMPTION
Fuel economy can be improved by
avoiding:
²lack of regular, scheduled
maintenance
²excessive speed
²rapid acceleration
²extended idle

HAZARD LIGHTS CONTROL
Use only in an emergency to warn
traffic of vehicle breakdown,
approaching danger, etc. The
hazard flashers can be operated
when the ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn
the flashers off.
FUEL PUMP SHUT-OFF SWITCH
If the engine cranks but does not
start after a collision, the fuel
pump shut-off switch may have
been activated. The ªFuel Resetº
indicator light will illuminate in the
instrument cluster. The shut-off
switch is a device intended to stop
the electric fuel pump when your
vehicle has been involved in a
substantial jolt.
1. Turn the ignition switch to the
OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset
the fuel pump shut-off switch by
pushing in the button on the
switch.
4. Turn the ignition switch to the
ON position. Pause for a few
Roadside emergencies
135

seconds and return the key to the
OFF position.
5. Make a further check for leaks
in the fuel system.
The fuel pump shut-off switch is
located in the passenger's foot
well, behind the kick panel.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse
may have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any
electrical components.
