GM Service Manual Online
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 an automatic transmission shift lever in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R).
  3. Turn off the engine and do not restart while the vehicle is raised.
  4. Do not allow passengers to remain in the vehicle.
To be even more certain the vehicle will not move, you should put 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.

Removing the Flat Tire and Installing the Spare Tire


Object Number: 810378  Size: B3
  1. If your vehicle has a wheel cover or hubcap that has plastic wheel nut caps, then loosen the plastic nut caps (you may need to use the wheel wrench to loosen them). Do not pry off wheel covers or center caps that have plastic wheel nut caps. Then remove the wheel cover or center cap.

  2. Object Number: 812251  Size: B3
  3. Then use the wheel wrench to loosen all the wheel nuts. Don't remove them yet.

  4. Object Number: 810377  Size: B3
  5. Position the jack and raise the jack head until it fits firmly into the notch in the vehicle's frame nearest the flat tire. Put the compact spare tire near you.
  6. 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.

  7. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit underneath the wheel well.
  8. Remove all of the wheel nuts.
  9. Remove the flat tire.

  10. 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.

  11. Install the compact spare tire.

  12. Object Number: 810375  Size: B3
  13. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

  14. Object Number: 812488  Size: B3
  15. Lower the vehicle by turning the wheel wrench counterclockwise. Lower the jack completely.

  16. Object Number: 808642  Size: A2
  17. Tighten the wheel nuts firmly in a crisscross sequence, as shown.

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.

Notice: Wheel covers will not fit on your vehicle's compact spare. If you try to put a wheel cover on the compact spare, the cover or the spare could be damaged.

Storing the Flat Tire and Tools

Caution: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

Store the flat tire in the compact spare tire compartment. Place the tire in the compartment, then secure the adapter and wing nut. Place the cover and the nut on top of the flat tire. Store the jack and the wrench in the foam tray.
