Bulb Replacement
High Intensity Discharge Headlamps (HID) — If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of this,
you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to an
authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE: On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are turned
on, there is a blue hue to the lamps. This diminishes and
becomes more white after approximately 10 seconds, as the
system charges.
Halogen Headlamps — If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.

FUSES
WARNING!
•When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Failure
to use proper fuses may result in serious personal
injury, fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is
off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.
• If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.
General Information
The fuses protect electrical systems against excessive cur-
rent. When a device does not work, you must check the electri-
cal circuit inside the fuse for a break/melt.
Also, please be aware that when using power outlets for
extended periods of time with the engine off may result in
vehicle battery discharge.

JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is on
a jack.
• The jack is designed to be used as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.
Jack Location
The scissor-type jack and tire changing tools are located in
rear cargo area, below the load floor. NOTE:
The funnel for the Cap-Less Fuel System is located
on top of the spare tire. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle. For vehicles not
equipped with a spare tire, the fuel filler funnel is stored in
the left storage bin under the load floor. For more informa-
tion on the Cap-Less Fuel System refer to “Refueling The
Vehicle” in “Starting And Operating” in this manual.

WARNING!(Continued)
•Block the wheel diagonally opposite the wheel to be
raised.
• Set the parking brake firmly and set the transmission
in PARK.
• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
1. Remove the spare tire, jack, and tools from storage.
2. Loosen (but do not remove) the wheel lug nuts by turning them to the left, one turn, while the wheel is still
on the ground.

8. Position the spare wheel/tire on the vehicle and installthe lug nuts with the cone-shaped end toward the
wheel. Lightly tighten the nuts.
CAUTION!
Be sure to mount the inflatable spare tire with the
valve stem facing outward. The vehicle could be dam-
aged if the inflatable spare tire is mounted incorrectly.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
9. Lower the vehicle by turning the jack screw counter- clockwise, and remove the jack and wheel blocks.
10. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. For correct lug nut
torque refer to Torque Specifications in “Technical
Specifications”. If in doubt about the correct tightness,
have them checked with a torque wrench by your
authorized dealer or at a service station.
11. Lower the jack to the fully closed position and return it and the tools to the proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the cargo area.

WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
Release. Activating the Manual Park Release will al-
low your vehicle to roll away if it is not secured by the
parking brake or by proper connection to a tow vehicle.
Activating the Manual Park Release on an unsecured
vehicle could lead to serious injury or death for those
in or around the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Open the center console and locate the Manual Park Release cover, remove it by snapping the cover away
from the console hinges.

IN CASE OF EMERGENCY 429

WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
•Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
(Continued)
CAUTION! (Continued)
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
the “Starting and Operating” section.
NOTE: Vehicles equipped with Quadra-Lift must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to the section
on Quadra-Lift for more information. If the vehicle cannot
be placed in Transport mode (for example, engine will not
run), tie-downs must be fastened to the axles (not to the
body). Failure to follow these instructions may cause fault
codes to be set and/or cause loss of proper tie-down
tension.
