The sliding tray and inside bin can
be hooked on the side or rear of the
console for extra storage.
AUXILIARY POWER POINT (12VDC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
•On the instrument panel
•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 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.

WARNING:Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly one or two degrees from the upright position.
WARNING:Do not put anything on or over the airbag module.
Placing objects on or over the airbag inflation area may cause
those objects to be propelled by the airbag into your face and torso
causing serious injury.
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.

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 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. 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
Canopy
could injure you as it deploys from the headliner.
WARNING:Do not attempt to service, repair, or modify the
Safety Canopy
System, 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 Canopy
System is provided.
WARNING:To reduce risk of injury, do not obstruct or place
objects in the deployment path of the inflatable Safety Canopy
.

PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
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.
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 pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
Fuses and relaysin theRoadside Emergencieschapter.

Note:With extended use, the flasher may run down your battery.
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.
