Tire change procedure
Preparing to change the tire
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park).
4. Apply the parking brake and turn
engine OFF.
5. Block the wheel that is diagonally
opposite the tire you are changing.
The parking brake is on the
transmission. Therefore, the vehicle
will not be prevented from moving
when a rear wheel is lifted, even if
the parking brake is applied. Be sure to block both directions of the
wheel that is diagonally opposite to the wheel that is being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
6. Remove the spare tire and jack from the storage location.
Roadside emergencies
49

7. Loosen the wheel nut by pulling up on the handle of the lug nut
wrench about one-half turn (counterclockwise). Do not remove the
wheel lug nuts until you raise the tire off the ground.
Replacing the tire
To lessen the risk of personal injury, do not put any part of your
body under the vehicle while changing a tire. Do not start the
engine when your vehicle is on the jack. The jack is only meant for
changing the tire.
8. Position the jack to raise the front or rear wheel.
•Never use the front or rear
differential as a jacking point.
Rear axle jacking points:
Front axle jacking points:
Place the jack under the front axle.
9. Raise the vehicle until the wheel is completely off the ground.
10. Remove the lug nuts with the lug nut wrench.
11. Replace the flat tire with the spare tire.
