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 may be equipped with a spare tire that can be used as
either 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

152

If your vehicle is equipped with 4WD, 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 (pick-up

trucks only)

Removing the spare tire (with spare tire carrier only)

1. The following tools are required to remove the spare tire:

2. The following steps are required to move the support bracket (if
equipped) away from the spare tire:
• With tapered end of lug wrench,

loosen the eyebolt on the support
bracket.

• Line up the eyebolt with the slot

in the support bracket.

• Slide the support bracket off the

eyebolt and move the support
bracket away from the spare tire.

3. Insert the hooked end of the jack
handle into the rear bumper
opening.

The handle will stop moving and
you will feel forward resistance to
turning when properly engaged.

4. Turn the handle counterclockwise
and lower the spare until you can
slide the tire rearward and the cable
is slack.

5. Remove the retainer through the center of the wheel.

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
effort to turn the jack handle
increases significantly and the spare
tire carrier ratchets when the tire is
raised to the stowed position. The spare tire carrier has a built-in ratchet
feature that will not allow you to overtighten.

4. Check that the tire lies flat to the frame assembly. Push against the
tire to make sure it is tightly seated under the vehicle. Loosen or
retighten if necessary.

positioned at a right angle of the slot on the support bracket.
