GM Service Manual Online
For 1990-2009 cars only

Your vehicle may have a tire sealant and compressor kit that is capable of temporarily sealing a puncture up to 6 mm in the tread area of the tire. There is no jack or spare tire. The kit inflates the tire with liquid sealant and air. The tire sealant and compressor kit can also be used to inflate an underinflated tire. After the tire is inflated to the recommended inflation pressure, see Inflation - Tire Pressure for more information, the vehicle must be driven for five miles to distribute the sealant in the tire and to seal the puncture. After driving five miles, the tire pressure must be rechecked and adjusted as needed. See "Using the Tire Sealant and Compressor" later in this section. Be sure to read and follow all of the tire sealant and compressor kit instructions.

After temporarily repairing a tire using the tire sealant and compressor kit, take your vehicle to an authorized dealer/retailer as soon as possible. If the sealant is removed within 100 miles (161 kilometers) of driving, then it is easier to clean from the tire and you are less likely to require a new tire.

The kit includes the following:


Object Number: 1482233  Size: B4
  1. Air Compressor

  2. Tire Sealant Canister

  3. Air Compressor Accessory Plug

  4. On/Off Switch

  5. Air Pressure Gage

  6. Air Only Hose

  7. Sealant/Air Hose

Accessing the Tire Sealant and Compressor Kit

To access the tire sealant and compressor kit:

  1. Open the liftgate. See Liftgate for more information

  2. Object Number: 1579719  Size: B4
  3. Remove the cargo cover.

  4. Object Number: 1696319  Size: B3
  5. Remove the foam retainer bolt (B) holding down the foam container.
  6. Remove the foam container (C).
  7. Remove the sealant and compressor kit (A) from its foam container.

Tire Sealant

When using the tire sealant and compressor kit during cold temperatures, warm the kit in a heated environment such as the vehicle for five minutes. This will help to inflate your tire faster.

Read and follow the safety handling instructions on the sealant canister.

Check the tire sealant expiration date. The sealant canister should be replaced before its expiration date. Replacement canisters are available at your local dealer/retailer. See "Removal and Installation of Sealant Canister" later in this section.

The sealant can temporarily seal a puncture up to 6 mm in the tread area of the tire. The sealant cannot seal sidewall damage, large punctures, or a tire that has unseated from the wheel. See Roadside Assistance Program if you need assistance.

The sealant can only be used to seal one tire. After usage, the sealant canister and the sealant filling hose assembly must be replaced at a dealer/retailer. See Removal and Installation of Sealant Canister later in this section.

Using the Tire Sealant and Compressor Kit to Temporarily Seal a Punctured Tire

Follow the directions closely for correct sealant usage.

  1. Do a safety check before proceeding. See If a Tire Goes Flat .
  2. Inspect the damaged tire.
  3. the sealant cannot seal sidewall damage, large punctures, or a tire that has unseated from the wheel. See Roadside Assistance Program .

    Do not remove any objects that have penetrated the tire.


    Object Number: 1977942  Size: B3
  4. Place the sealant and compressor kit on the ground and unwrap the sealant/air hose (G) from the compressor.
  5. Remove the valve stem cap from the flat tire by turning it counterclockwise.
  6. Attach the sealant/air hose (G) onto the tire valve stem. Turn it clockwise until tight.
  7. Make sure the sealant and compressor kit On/Off switch (D) is in the O (off) position.

  8. Remove the air compressor accessory plug (C) from the unit.
  9. Plug the air compressor accessory plug (C) into an accessory power outlet in the vehicle. See Accessory Power Outlet(s) for more information.
  10. Do not slam the door or close the window on the compressor accessory plug cord.

    Caution: Idling the engine in a closed-in place or with the climate control system off can cause deadly carbon monoxide (CO). See Engine Exhaust .

  11. Start the vehicle. See Starting the Engine . The vehicle must be running while using the air compressor.
  12. Caution: Overinflation could cause the tire to rupture, and you or others could be injured. Be sure to read the inflator instructions, and inflate the tire to its recommended pressure. Do not exceed 36 psi (248 kPa).

  13. Push the On/Off switch to the I (on) position.
  14. the tire sealant and compressor kit will inject sealant and air into the tire.

    The pressure gage (E) will initially show a high pressure while the compressor pushes the sealant into the tire. Once the sealant is completely dispersed into the tire, the pressure will quickly drop and start to rise again as the tire inflates with air only.

  15. Inflate the tire to the recommended inflation pressure using the air pressure gage (E) on the top of the unit. The recommended pressure can be found on the Tire Loading Information label. See Inflation - Tire Pressure .
  16. The pressure gage reading is slightly high while the compressor is on. Turn the compressor off to get an accurate pressure reading. The compressor may be turned on and off until the correct pressure is reached.

    Notice: If the recommended pressure cannot be reached after approximately 25 minutes, the vehicle should not be driven. The tire is too severely damaged and the tire sealant and compressor kit cannot inflate the tire. Remove the air compressor accessory plug from the accessory power outlet and unscrew the sealant/air hose from the tire valve or tire pressure monitoring sensor valve. See Roadside Assistance Program .

  17. Turn the compressor off by pushing the On/Off switch (D) to the O (off) position.
  18. Steps 12 through 20 must be done right after Step 11.

    The tire is not sealed and will continue to leak air until the vehicle is driven and the sealant is distributed in the tire.

    Be careful while handling the tire inflator components as they could be hot after usage.

  19. Unplug the air compressor accessory plug (C) from the accessory power outlet in the vehicle.
  20. Disconnect the sealant/air hose (G) from the tire valve stem by turning it counterclockwise and replace the tire valve stem cap.
  21. Wrap the sealant/air hose (G) around the air compressor channel to stow it in its original location.
  22. Stow the air compressor accessory plug (C) back in the air compressor. To do this, wrap the air compressor accessory plug, snap in the plug, and then push in the bottom and then the top of the wrapped air compressor accessory plug.

  23. Object Number: 1482234  Size: A2

    If the flat tire was able to be inflated to the recommended inflation pressure, remove the maximum speed label from the sealant canister.

  24. Place it in a highly visible location such as the inside of the upper left corner of the windshield or to the face of the radio/clock.
  25. The maximum speed label reminds you to drive cautiously and not to exceed 55 mph (90 km/h) until you have the damaged tire inspected and repaired.

    Caution: Storing the tire sealant and compressor kit 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 the tire sealant and compressor kit in its original location.

  26. Return the equipment to its original storage location in the vehicle.
  27. Immediately drive the vehicle 5 miles (8 km) to distribute the sealant evenly in the tire. Stop at a safe location and check the tire pressure, refer to Steps 1 through 8 under Using the Air Compressor without Sealant next in this section.
  28. Stop at a safe location and check the tire pressure, refer to Steps 1 through 11 under "using the Tire Sealant and Compressor Kit without Sealant to Inflate an Underinflated Tire (Not Punctured)" later in this section.
  29. If the tire pressure has fallen more then 10 psi (68 kPa), below the recommended inflation pressure, stop driving the vehicle. The tire is too severely damaged and the tire sealant and compressor kit cannot seal the tire. See Roadside Assistance Program for more information.

    If the pressure has not dropped more than 10 psi (68 kPa) below the recommended inflation pressure, inflate the tire back up to the recommended pressure.

  30. Wipe off any sealant from the wheel, tire and vehicle.
  31. Dispose of the sealant canister at a local dealer/retailer or in accordance with any local, state, and provincial codes and practices.
  32. After using the sealant canister, replace it with a new canister from a dealer/retailer.

  33. After temporarily sealing a tire with the tire sealant and compressor kit, take your vehicle to an authorized dealer/retailer to have the tire repaired or replaced.
