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 the vehicle's hazard warning flashers. See 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. 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.

  3. Turn the jack handle clockwise to raise the vehicle. Raise the vehicle far enough off the ground for the spare tire to fit underneath the wheel well.

    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.

    Caution: Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. If a jack is provided with the vehicle, only use it for changing a flat tire.

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.
