HAZARD WARNING FLASHERS
The 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 OVERHEATS
In 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 ve-
hicle. 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 com-
ing 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.
(Continued)
WARNING!(Continued)
•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.
Jack Storage Location

6. Block both the front and rear of the wheeldiagonally 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.
7. For vehicles equipped with Quadra-Lift® re-
fer to “Quadra-Lift® — If Equipped” in “Starting
And Operating” for further information on dis-
abling automatic leveling.
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.
• 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.”
(Continued)
WARNING!(Continued)
•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.

WARNING!
Do not connect the cable to the negative
post(-)of the discharged battery. The result-
ing 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 tested at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s bat-
tery, even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in long
enough without engine operation, the vehi-
cle’s battery will discharge sufficiently to de-
grade battery life and/or prevent the engine
from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Press
and hold the lock button on the shift lever. Then
shift back and forth between DRIVE and RE-
VERSE while gently pressing the accelerator.
NOTE:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
or less. Whenever the transmission remains
in NEUTRAL for more than 2 seconds, you
must press the brake pedal to engage DRIVE
or REVERSE.
Use the least amount of accelerator pedal pres-
sure that will maintain the rocking motion with-
out spinning the wheels or racing the engine.
302

NOTE:
Press theESC Offswitch (if necessary), to
place the Electronic Stability Control (ESC)
system in Partial Off mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol” in “Starting And Operating” for further
information. Once the vehicle has been
freed, press the ESC Offswitch again to
restore ESC On mode.
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
prolonged efforts to free a stuck vehicle.
CAUTION!
•
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.
•Revving the engine or spinning the wheels
too fast may lead to transmission over-
heating and failure. It can also damage the
tires. Do not spin the wheels above
30 mph (48 km/h) while in gear (no trans-
mission 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
(Continued)
WARNING!(Continued)
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.
TOW EYES
Your 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.
303

WARNING!
Stand clear of vehicles when pulling with tow
eyes. Tow straps and chains may break,
causing serious injury.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever can-
not be moved out of the PARK position, you can
use the following procedure to temporarily
move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Remove the rubber liner from the cupholder
(located next to the shifter on the center con-
sole).
4. Using a small screwdriver or similar tool,
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. Insert the screwdriver or similar tool into the
access hole, and push and hold the override
release 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 cupholder liner.
TOWING A DISABLED
VEHICLE
This 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 towed
as 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
cause loss of proper tie-down tension.
