The auxiliary power points are
located on the instrument panel.
Do not use the power point for
operating the cigarette lighter
element (if equipped).
To prevent the fuse from being
blown, do not use the power
point(s) over the vehicle capacity of
12 VDC/180W. If the power point or cigar lighter socket is not working, a
fuse may have blown. Refer toPassenger Compartment Fuse Panel
and Fuses and relays in theRoadside Emergencies chapter for fuse
ratings and information on checking and replacing fuses.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
Cigar/Cigarette lighter (if equipped)
Do not plug optional electrical accessories into the cigarette lighter
socket.
Do not hold the lighter in with your hand while it is heating, this will
damage the lighter element and socket. The lighter will be released from
its heating position when it is ready to be used.
Improper use of the lighter can cause damage not covered by your
warranty.
POWER WINDOWS (IF EQUIPPED)
WARNING: Do not leave children unattended in the vehicle and
do not let children play with the power windows. They may
seriously injure themselves.
WARNING: When closing the power windows, you should verify
they are free of obstructions and ensure that children and/or
pets are not in the proximity of the window openings.

Driving while you tow
When towing a trailer:
• Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
• 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 the
Driving 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.

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: When the key is in the ignition and in the 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.
Note: On some vehicles, when the key is in the OFF position, the
brake-shift interlock feature will prevent the automatic transmission shift
lever from being moved out of the P (Park) position without the brake
pedal being depressed.
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 to Fuses and relaysin theRoadside
Emergencies chapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the
LOCK position and remove the key whenever you leave your
vehicle.

The fuel pump shut-off switch is
located on the right side of the
passenger footwell, behind the fuse
panel door.
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 for 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.
