Jack/Spare Tire Stowage
Jack Location
The scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.Spare Tire Stowage
The 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
CAUTION!
Always lift or jack the vehicle from the
correct jacking points. Failure to follow
this information could cause damage to
the vehicle or underbody components.
NOTE:
To assist with changing a spare tire, the air
suspension system (if equipped) has a fea-
ture which allows the automatic leveling to be
disabled.
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 gear selector into PARK.
5. Turn the ignition OFF.
6. Block both the front and rear of the wheel
diagonally opposite of the jacking posi-
tion. For example, if changing the right
front tire, block the left rear wheel.NOTE:
Passengers should not remain in the ve-
hicle when the vehicle is being jacked.
7. For vehicles equipped with Quadra-Lift, refer to “Quadra-Lift — If Equipped” in
“Starting And Operating” in the Owners
Manual at

Jacking Instructions
WARNING!
Carefully follow these tire changing warn-
ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface asfar from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Chock 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.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, 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 indi-
cated 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.

5. For a rear tire, place the jack in the slot onthe rear tie-down bracket, just forward of
the rear tire (as indicated by the triangular
lift point symbol on the sill molding). Do
not raise the vehicle until you are sure the
jack is fully engaged. 6. Raise the vehicle by turning the jack
screw clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire. Minimum tire lift provides
maximum stability.
WARNING!
Raising the vehicle higher than necessary
can make the vehicle less stable. It could
WARNING!
slip off the jack and hurt someone near it.
Raise the vehicle only enough to remove
the tire.
7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the ve- hicle and install the lug nuts with the
cone-shaped end toward the wheel.
Lightly tighten the nuts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in serious
injury.Front Jacking LocationRear Jacking Location

CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged if the spare tire is
mounted incorrectly.
9. Lower the vehicle by turning the jack screw counterclockwise, 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.
The correct tightness of each lug nut is
130 ft-lbs (176 N·m). If in doubt about
the correct tightness, have them
checked with a torque wrench by your
authorized dealer or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
11. Lower the jack to the fully closed posi- tion and return it and the tools to the
proper positions in the foam tray.
12. Remove the small center cap and se- curely store the road wheel in the cargo
area. 13. Have the aluminum road wheel and tire
repaired as soon as possible, properly
secure the spare tire with the special
wing nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit foam tray,
and latch the rear load floor cover.
NOTE:
Do not drive with the spare tire installed for
more than 50 miles (80 km) at a max speed
of 50 mph (80 km/h).

4. 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. The correct
tightness of each lug nut is 130 ft-lbs
(176 N·m). If in doubt about the correct
tightness, have them checked with a
torque wrench by your authorized dealer
or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.JUMP-STARTING
If your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so
please follow the procedures in this section
carefully.
WARNING!
Do not attempt jump-starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump-Starting
The battery in your vehicle is located under
the passenger's front seat. There are remote
locations located under the hood to assist in
jump-starting.
221

WARNING!
• Take care to avoid the radiator coolingfan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan
blades.
WARNING!
• Remove any metal jewelry such as rings,watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
NOTE:
Be sure that the disconnected ends of the
cables do not touch while still connected to
the either vehicle.
1. Set the parking brake, shift the automatic transmission into PARK and turn the igni-
tion to LOCK.
2. Turn off the heater, radio, and all unnec- essary electrical accessories.
3. Remove the protective cover over the re- mote positive (+)battery post. Pull up-
ward on the cover to remove it. 4. If using another vehicle to jump-start the
battery, park the vehicle within the
jumper cables reach, set the parking
brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting proce-
dure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged ve-
hicle.
