The auxiliary power point is located
in the instrument panel.
A second auxiliary power point is
located on the rear side of the
center console.
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 to
Fuses 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 (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:Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses. Contact your
authorized dealer as soon as possible.
WARNING:Modifications to the front end of the vehicle,
including frame, bumper, front end body structure, tow hooks
and B-pillar surrounding parts may affect the performance of the
airbag sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING:Additional equipment may affect the performance of
the airbag sensors increasing the risk of injury.
Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
WARNING:Airbags can kill
or injure a child in a child
seat.NEVERplace a rear-facing
child seat in front of an active
airbag. If you must use a
forward-facing child seat in the
front seat, move the seat all the
way back.

WARNING:Do not attempt to service, repair, or modify the
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. See an authorized dealer.
WARNING:All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.
How does the side airbag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
The side airbag system consists of
the following:
•An inflatable nylon bag (airbag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•A special seat cover designed to allow airbag deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located on the lower portion of the b-pillar (one on
each side of the vehicle).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. If the front passenger sensing system
detects an empty seat, the front passenger seat-mounted side airbag will
be deactivated. The airbag was designed to inflate between the door
panel and occupant to further enhance the protection provided
occupants in side impact collisions.

Safety Canopysystem
WARNING:Do not place
objects or mount equipment
on or near the headliner at the
siderail that may come into
contact with a deploying Safety
Canopy. Failure to follow these
instructions may increase the risk
of personal injury in the event of a
collision.
WARNING:Do not lean your head on the door. The Safety
Canopycould injure you as it deploys from the headliner.
WARNING:Do not attempt to service, repair, or modify the
Safety Canopysystem, its fuses, the A, B, or C pillar trim, or
the headliner on a vehicle containing a Safety Canopy. Contact your
authorized dealer as soon as possible.
WARNING:All occupants of the vehicle including the driver
should always wear their safety belts even when an airbag SRS
and Safety Canopysystem is provided.
WARNING:To reduce risk of injury, do not obstruct or place
objects in the deployment path of the inflatable Safety Canopy.

WARNING:Vehicles with a higher center of gravity such as
utility vehicles and trucks handle differently than vehicles with a
lower center of gravity. Utility vehicles and trucks arenotdesigned for
cornering at speeds as high as passenger cars any more than low-slung
sports cars are designed to perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in
these vehicles. Failure to drive cautiously could result in an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death.
WARNING:Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Do not overload
your vehicle and use extra precautions, such as driving at slower
speeds, avoiding abrupt steering changes and allowing for increased
stopping distance, when driving a heavily loaded vehicle. Over-loading
or loading the vehicle improperly can deteriorate handling capability
and contribute to loss of vehicle control and vehicle rollover.
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, it is possible that a fuse
has blown or the vehicle’s brakelamps are not operating properly. Refer
toFuses and relaysin theRoadside Emergencieschapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to off, then remove the key.

FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
This switch is located in the front
passenger’s footwell, behind a
flip-up cover, by the kick panel
access cover.
To reset the switch:
1. Turn the ignition to the off
position.
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 to the on
position.
5. Wait a few seconds and return
the key to the off position.
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.
