accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
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 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 (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.

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:
