and possibly result in an electrical sys-
tem failure.
IN CASE OF EMERGENCY

CAUTION!
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
JACKING AND TIRE
CHANGING
Run Flat Tires — SRT Models
SRT models are equipped with “run flat”
tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80 km) at
55 mph (88 km/h). Tire service should be
obtained to avoid prolonged run flat feature
usage.
WARNING!
Do not exceed 50 mph (80 km/h) if the
“Tire Pressure Monitoring Telltale Light” is
illuminated. Vehicle handling and braking
may be reduced. You could have a collision
and be severely or fatally injured.
Jack Location
The scissor-type jack and tire changing tools
are located in the rear cargo area, below the
load floor.

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. Apply 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 Owner’s
Manual for further information on dis-
abling automatic leveling.
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 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.
• Apply 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

WARNING!
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.
• If working on or near a roadway, be
extremely 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.
• The jack should be used on level firm
ground wherever possible.
• It is recommended that the wheels of
the vehicle be chocked, and that no
person should be remain in a vehicle
that is being jacked.
• No person should place any portion of
their body under a vehicle that is sup-
ported by a jack.
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.

4. For the front axle, place the jack on the
body flange just behind the front tire as
indicated by the triangular lift point sym-
bol on the sill molding.Do not raise the
vehicle until you are sure the jack is fully
engaged.5. For a rear tire, place the jack in the slot on
the 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.
CAUTION!
Do NOT raise the vehicle by the body side
sill molding. Be sure the jack is placed in
the proper engagement location on the
inside of the panel. Damage of the vehicle
may occur if the procedure is not properly
followed.

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
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.
CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged 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 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.
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 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).
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the
cone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the wheel nuts
WARNING!
fully until the vehicle has been lowered.
Failure to follow this warning may result in
serious injury.
3. Lower the vehicle to the ground by turning
the jack handle counterclockwise.
4. Refer to “Torque Specifications” in
“Technical Specifications” for proper lug
nut torque.
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.
