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 the shift lever in P (Park).
  3. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear - not in N (Neutral).
  4. Turn off the engine and do not restart while the vehicle is raised.
  5. Do not allow passengers to remain in the vehicle.
To be even more certain the vehicle will not move, 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.

    Rear Wheel Location


    Object Number: 810568  Size: B2
  5. Under the vehicle near each wheel, there are knobs in the vehicle's frame. Raise the jack two inches (51 mm) before positioning the jack. Raise the jack lift head until it fits firmly onto the knobs nearest to the flat tire.
  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 cause personal injury and damage to the vehicle. If you try to use the jack when it hasn't been raised at least two inches (51 mm), the jack may not hold up the vehicle, and you or others could be injured. To help avoid personal injury and vehicle damage, be sure to open the jack at least two inches (51 mm) before you fit the lift head into the proper location.

  11. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.
  12. 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.

  13. Place the spare on the wheel mounting surface.

    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.

  19. When you reinstall the full-size wheel and tire, you must also reinstall the plastic nut caps.
  20. Tighten the plastic nut caps by hand. Then tighten them one half turn with the wheel wrench. Do not overtighten the nut caps or they may break.

Storing a Flat or Spare 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.
