2. Slide the wheel under the
vehicle and install the retainer
through the wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its
original position underneath the
vehicle. The jack handle ratchets
when the tire is raised to the
stowed position. It will not allow
you to overtighten.

On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior
to jacking, hoisting or towing
your vehicle.
Refer to the instruction sheet
(located behind the interior trim
access panel with the jack) for
detailed tire change instructions.

3. Block the diagonally opposite

4. Obtain the spare tire and jack
from their storage locations.
5. Use the tip of the lug wrench to
remove any wheel trim.
6. Loosen each wheel lug nuts
one-half turn counterclockwise but
do not remove them until the
wheel is raised off the ground.
7. Turn OFF the air suspension
switch (if equipped).
8. Position the jack according to
the following guides and turn the
jack handle clockwise until the
wheel is completely off the ground.
When one of the rear wheels is off
the ground, the transmission alone
will not prevent the vehicle from
moving or slipping off the jack,
even if the transmission is in P
(Park). To prevent the vehicle
from moving when you change the
tire, be sure that the parking brake
is set and the diagonally opposite
wheel is blocked. If the vehicle
slips off the jack, someone could
be seriously injured.

Follow these guidelines when using
snow tires and chains:
²Use only SAE Class S chains.
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the
chains rub or bang against your
vehicle, stop and re-tighten the
chains. If this does not work,
remove the chains to prevent
damage to your vehicle.
²If possible, avoid fully loading
your vehicle.
²Do not use tire chains on
aluminum wheels. Chains may
chip the wheels.
²Remove the tire chains when
they are no longer needed. Do
not use tire chains on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove
these components from your
vehicle when using snow tires
and chains.
