fuse may have blown. Refer toFuses and relaysin theRoadside
Emergencieschapter for information on checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
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.
Note:Improper use of the lighter can cause damage not covered by your
warranty, and can result in fire or serious injury.
POWER WINDOWS
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.
Press and pull the window switches
to open and close windows.
•Push down (to the first detent)
and hold the switch to open.

AUTOMATIC TRANSMISSION OPERATION
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 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 off, then remove the key.
2. Remove the rubber pad at the
bottom of the cup holder to locate
the access cap of the floor shifter
assembly.
3. Using a screwdriver (or
equivalent), remove the access
panel and depress the shifter lever
on the shift mechanism.
4. Apply the brake and shift into N
(Neutral).
5. Return the cover plug to the console access hole. 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.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

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.
