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!

ings to help prevent personal injury or
damage to your vehicle:

SERVICING AND MAINTENANCE

Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica-tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
WARNING!
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
