WARNING: Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Extra
precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn
ignition key to LOCK, then
remove the key.
2. Insert the key and turn it to
OFF.Apply the brake pedal
and shift to N (Neutral).
WARNING: In the ignition OFF position, the automatic
transmission shift lever can be moved from the P (Park)
position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.

Driving while you tow
When towing a trailer:
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To 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 transmissionsection in this
chapter.
²Anticipate stops and brake gradually.
²Do 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
²Practice 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.
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.
²To 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).

This switch is located in the front
passenger's footwell, by the kick
panel access cover.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset
the switch by pushing in on the
reset button.
4. Turn the ignition ON.
5. Wait a few seconds and return
the key to OFF.
6. Make another check of leaks.
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.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle's main electrical systems
from overloads.
WARNING: Always disconnect the battery before servicing high
current fuses.
WARNING: To reduce risk of electrical shock, always replace
the cover to the Power Distribution Box before reconnecting
the battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and specificationschapter.
