Hitches
For towing trailers up to 907 kg (2,000 lb), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the
underbody structure. Use a frame-mounted weight distributing hitch for
trailers over 907 kg (2,000 lb).
Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Underbody mounted hitches are acceptable if
they are installed properly. Follow the towing instructions of a reputable
rental agency.
Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. 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.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.WARNING: 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.
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 all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.

Using a step bumper
The optional step 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
907 kg (2,000 lb.) trailer weight and 91 kg (200 lb.) tongue weight
capability.
The rated capacities (as shown in this guide) for trailer towing with the
factory bumper are only valid when the trailer hitch ball is installed
directly into the ball hole in the bumper. Addition of bracketry to either
lower the ball hitch position or extend the ball hitch rearward will
significantly increase the loads on the bumper and its attachments. This
can result in the failure of the bumper or the bumper attachments. Use
of any type of hitch extensions should be considered abuse.
Trailer tow connector
The trailer tow connector is located
under the rear bumper, on the
driver’s side of the vehicle.
Refer to the following chart for information regarding the
factory-equipped trailer tow connector:

Driving while you tow
When towing a trailer:
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in this
chapter.)
• Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in theInstrument cluster
chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your service maintenance section for
more information.
Trailer towing tips
• Practice turning, stopping and backing up 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.
• Allow more distance for stopping with a trailer attached.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.

•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
• Vehicles 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
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
• do not allow the static water level to rise above the bottom edge of
the rear bumper.
• do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
• causing internal damage to the components.
• affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
4x2 equipped with a manual transmission:
Before you have your vehicle towed:
• Release the parking brake.
• Move the gearshift to the neutral position.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• The maximum recommended speed is 88 km/h (55 mph).
• The maximum recommended distance is unlimited.

OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens: 1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
4. Check whether coolant or steam is escaping from under the hood or from the engine compartment.

It is not recommended that the vehicle be operated in 4WD modes with
a “temporary” (i.e. dissimilar size) spare. If 4WD operation is necessary,
do not operate above speeds of 16 km/h (10 mph) or for distances above
80 km (50 miles).WARNING: If you use the temporary spare tire continuously or
do not follow these precautions, the tire could fail, causing you
to lose control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tire do not:
• exceed 80 km/h (50 mph) or drive further than 3,200 km (2,000
miles) total under any circumstances
• load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
• tow a trailer
• use more than one temporary spare tire at a time
Use of a temporary spare tire at any one wheel location can lead to
impairment of the following:
• Handling, stability and braking performance
• Comfort and noise
• Ground clearance and parking at curbs
• Winter driving capability
Conventional spare tire information (if equipped)
If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
