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 (in a safe manner) 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.
Improper use of the lighter can cause damage not covered by your warranty.
POWER WINDOWS
Do not leave children unattended in the vehicle and do not let
children play with the power windows. They may seriously injure
themselves.
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.
•Pull up (to the first detent) and
hold the switch to close.
Rear Window Buffeting:When one or both of the rear windows are open,
the vehicle may demonstrate a wind throb or buffeting noise. This noise can
be alleviated by lowering a front window approximately two to three inches.

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.
Do not drive your vehicle until you verify that the brakelamps
are working.
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.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.

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.
