HAZARD WARNING FLASHERSThe Hazard Warning flasher switch is located
on the switch bank just above the climate
controls.Press the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals will
flash on and off to warn oncoming
traffic of an emergency. Press the switch a
second time to turn off the Hazard Warning
flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.IF YOUR ENGINE OVERHEATSIn any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease the engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age 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.
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.

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 danger-
ous. 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 pur-
poses. The vehicle should be jacked on a
firm level surface only. Avoid ice or slippery
areas.
Jack LocationThe scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.
Spare Tire StowageThe spare tire is stowed under the load floor in
the rear cargo area and is secured to the body
with a special wing nut.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of
the vehicle closest to moving traffic, pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF. 6. Block both the front
and rear of the wheel
diagonally opposite of
the jacking position. For
example, if changing
the right front tire, block
the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.

Jacking Instructions
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
• Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the
wheel to be raised.
• Set the parking brake firmly and set an
automatic 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.
(Continued)
WARNING!(Continued)
• Do not get under the vehicle when it is on a
jack.
• 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 ex-
tremely 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.
3. Assemble the jack and jacking tools.
CAUTION!
Do not attempt to raise vehicle by jacking on
locations other than those indicated in the
Jacking Instructions for this vehicle.Jack Warning Label

2. Connect the opposite end of the positive(+)
jumper cable to the positive (+)post of the
booster battery.
3. Connect the negative end (-)of the jumper
cable to the negative (-)post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to the remote negative (-)post of
the vehicle with the discharged battery.
WARNING!
Do not connect the cable to the negative post
(-) of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few min-
utes, and then start the engine in the vehicle
with the discharged battery. Once the engine is started, remove the jumper
cables in the reverse sequence:
6. Disconnect the negative
(-)jumper cable
from the remote negative (-)post of the dis-
charged vehicle.
7. Disconnect the negative end (-)of the
jumper cable from the negative (-)post of the
booster battery.
8. Disconnect the opposite end of the positive
(+) jumper cable from the positive (+)post of
the booster battery.
9. Disconnect the positive (+)end of the
jumper cable from the remote positive (+)post
of the discharged vehicle.
10. Reinstall the protective cover over the re-
mote positive (+)battery post of the discharged
vehicle.
If frequent jump-starting is required to start your
vehicle you should have the battery and charg-
ing system inspected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the
vehicle power outlets draw power from the
vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in
long enough, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
FREEING A STUCK VEHICLEIf the vehicle becomes stuck in snow, sand or
mud, it can often be moved by a rocking
motion. Move the shift lever rhythmically be-
tween DRIVE and REVERSE while applying
slight pressure to the accelerator. In general,
the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning
the wheels or racing the engine is most effec-
tive.
289

CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the shift lever in
NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a
stuck vehicle.
CAUTION!
•When “rocking” a stuck vehicle by moving
between DRIVE and REVERSE, do not
spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may result.
• Revving the engine or spinning the wheels
too fast may lead to transmission overheat-
ing and failure. It can also damage the tires.
Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).
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 sec-
onds continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
TOW EYESYour vehicle is equipped with tow eyes, which
are mounted in the front and the rear.
CAUTION!
Tow eyes are for emergency use only, to
rescue a vehicle stranded off road. Do not use
tow eyes for tow truck hookup or highway
towing. You could damage your vehicle. Tow
straps are recommended when towing the
vehicle; chains may cause vehicle damage.
WARNING!
Stand clear of vehicles when pulling with tow
eyes. Tow straps and chains may break, caus-
ing serious injury.
SHIFT LEVER OVERRIDEIf a malfunction occurs and the shift lever
cannot be moved out of the PARK position, you
can use the following procedure to temporarily
move the shift lever:
1. Firmly apply the parking brake.
2. Turn the engine OFF.
3. Remove the rubber liner from the cupholder
(located next to the shifter on the center con-
sole).
4. Using a screwdriver or similar tool, carefully
remove the shift lever override access cover,
located on the bottom of the cupholder.

5. Press and maintain firm pressure on the
brake pedal.6. Using the screwdriver or similar tool, press
and hold the shift lock lever down.
7. Move the shift lever to the NEUTRAL posi-
tion.
8. The vehicle may then be started in NEU-
TRAL.
9. Reinstall the shift lever override access
cover and install the rubber liner into the cup-
holder.
TOWING A DISABLED VEHICLEThis section describes procedures for towing a
disabled vehicle using a commercial wrecker
service. If the transmission and drivetrain are
operable, disabled vehicles may also be towedas described under “Recreational Towing” in
the “Starting And Operating” section.
NOTE:
Vehicles equipped with Quadra-Lift™ must
be lowered to the Park (lowest) level, and
have automatic leveling disabled, before ty-
ing 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 lowered to the Park level
(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 loss
of proper tie-down tension.
