For 1990-2009 cars only

If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.

Caution: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:

  1. Set the parking brake firmly.
  2. Put the shift lever in PARK (P).
  3. Turn off the engine and do not restart while the vehicle is raised.
  4. Do not allow passengers to remain in the vehicle.
  5. Put the wheel blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side, at the opposite end of the vehicle.

    Object Number: 864534  Size: B3
  1. Slide the ratchet onto the wheel wrench with the DOWN mark facing you.
  2. Turn the ratchet counterclockwise to loosen the wheel nuts. Don't remove them yet.
  3. You will now need to jack the vehicle up using the instructions following.

  4. Assemble the jack and tools as follows:
  5. Front Flat Tire: Attach the jack handle (E) with the hook end connected to the u-hook/clevis on the jack (A). Slide the ratchet (F) onto the jack handle (E) with the UP mark facing you.


    Object Number: 864541  Size: B2
  6. Rear Flat Tire: Attach the jack handle extension (D) to the jack handle (E) and then press the clip (arrow) so it engages. Then attach the jack handle (E) with the hook end connected to the u-hook/clevis on the jack (A). Slide the ratchet (F) onto the jack handle extension (D) with the UP mark facing you.
  7. Turn the ratchet (F) clockwise to raise the jack head to the lifting point.
  8. Front Position

    Rear Position


    Object Number: 864542  Size: A3

    Rear Flat Tire: Place the jack under the curved rear axle pad. Make sure the jack head is positioned so that the rear axle pad is resting securely on the jack head.

    Caution: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

    Caution: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

  9. Turn the ratchet clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to clear the ground.

  10. Object Number: 864527  Size: A3

    Remove all the wheel nuts and take off the flat tire.


    Object Number: 811105  Size: A2

    Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

    Caution: Rust or dirt on a wheel or other parts to which it is fastened, can make the wheel nuts become loose and eventually the wheel could come off and cause a crash. Always remove all rust and dirt from wheels and other parts.

    Caution: Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash.


    Object Number: 864528  Size: A3

    After mounting the spare, put the wheel nuts back on with the rounded end of the nuts toward the wheel.

  11. Tighten each wheel nut by hand. Then use the ratchet/wheel wrench to tighten the nuts, with the UP mark facing you, clockwise until the wheel is held against the hub. You will not be tightening the nuts fully yet.
  12. Front Position


    Object Number: 864538  Size: A3

    Rear Position


    Object Number: 864553  Size: A3
  13. Lower the vehicle by turning the ratchet counterclockwise, with the DOWN mark facing you. Lower the jack completely.

  14. Object Number: 864517  Size: A2

    Tighten the nuts firmly in a crisscross sequence as shown by turning the ratchet clockwise, with the UP mark facing you.

    Caution: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications for wheel nut torque specification.

    Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications for the wheel nut torque specification.

  15. When you install the wheel and tire, you must also reinstall the center cap. Place the cap on the wheel and tap it into place until it sits flush with the wheel.

  3. Tighten the nut (D) by hand until the tire retainer plate (C) is snug against the wheel.

  4. Object Number: 864522  Size: A3

    Then use the ratchet and spanner to tighten the nut firmly. Try to move the tire back and forth slightly to be sure it is secure.
