CHANGING THE TIRES
If you get a flat tire while driving,
do not apply the brake heavily.
Instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.
Spare tire information
Your vehicle is equipped with a
spare tire that may be used as a
spare or a regular tire. The spare
tire is not equipped with wheel
trim. The wheel trim from the
original wheel/tire may be used on
the spare.
Roadside emergencies

ProCarManuals.com

If your vehicle is equipped with
4WD or AWD, a spare tire of a
different size than the road
tires should not be used. Such
a tire could result in damage to
driveline components and make
the vehicle difficult to control.
Location of the spare tire and
tools
The spare tire and tools for your
vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just forward of the
rear bumper
Jack, lug nut wrench Under the seat
Jack handle On top of the radiator support at the
front of the engine compartment
Removing the spare tire
1. Insert the jack handle into the
rear bumper opening.
The handle will stop moving and
forward resistance to turning will
be felt when properly engaged.
2. Turn the handle
counterclockwise until tire is
lowered to the ground, the tire can
be slid rearward and the cable is
slightly slack.
3. Remove the retainer from the
spare tire.
Stowing the spare
1. Lay the tire on the ground with
the valve stem facing up.

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.
Tire change procedure
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.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park).

3. Block the diagonally opposite
wheel.
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.
