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: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.

Power distribution box
The power distribution box is
located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle’s main electrical systems
from overloads.
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace
the cover to the Power Distribution Box before reconnecting the
battery or refilling fluid reservoirs.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer toTire Pressure Monitoring System
(TPMS)in theTires, Wheels, and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your Tire
Pressure Monitoring System and should not be used.
