Place the gear selector into PARK (P).

Turn the ignition OFF.

Block both the front and rear of the wheel diagonally opposite of the jacking position. For example, if changing the driver’s front tire, block the passenger’s rear wheel.

NOTE:

Turn on the Hazard Warning Flashers.

Apply the parking brake.

Passengers should not remain in the vehicle when the vehicle is being lifted or raised.

JACKING INSTRUCTIONS

Remove the spare tire, jack, and tools from storage. Turn the wing nut counter- clockwise to remove the spare tire.

(Continued)

Loosen (but do not remove) the wheel lug nuts, using the lug wrench by turning them counterclockwise, one turn, while the wheel is still on the ground.

Assemble the jack and jacking tools.

Jacking Locations

For the front axle, place the jack on the body flange just behind the front 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.

Depending on vehicle trim level, certain models come equipped with Rock Rails which have a different front lifting point location. Also, the triangular symbols are not visible for this trim package.

NOTE:

The jack must be placed straight on with handle facing outwards. See the following Front Jacking Location images for reference. The position of the front jack is the same for all trim levels.

Front Jacking Location - Rock Rail

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.

The rear lifting point location is the same for all trim levels.

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.

Remove the lug nuts and wheel.

Position the spare wheel/tire on the vehicle and install the lug nuts with the

cone-shaped end toward the wheel. Lightly tighten the nuts.

Lower the vehicle by turning the jack screw counterclockwise, and remove the jack and wheel blocks.

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 page 385. If in doubt about the correct tightness, have them checked with a torque wrench by an authorized dealer or at a service station.

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.

Lower the jack to the fully closed position and return it and the tools to the proper positions in the foam tray.

Remove the small center cap and securely store the road wheel in the cargo area. Turn the wing nut clockwise until secured.

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.

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).
