Buick Regal: Tire Sealant and Compressor Kit (I)

Your vehicle may have one of the two inflator kits described following.

Warning: Idling a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled.

It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation.

Warning: Overinflating a tire could cause the tire to rupture and you or others could be injured. Be sure to read and follow the tire sealant and compressor kit instructions and inflate the tire to its recommended pressure. Do not exceed the recommended pressure.

Warning: 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.

If this vehicle has a tire sealant and compressor kit, there may not be a spare tire or tire changing equipment, and on some vehicles there may not be a place to store a tire.

The tire sealant and compressor can be used to temporarily seal punctures up to 4 mm (0.16 in) in the tread area of the tire. It can also be used to inflate an underinflated tire.

If the tire has been separated from the wheel, has damaged sidewalls, or has a large puncture, the tire is too severely damaged for the tire sealant and compressor kit to be effective. Read and follow all of the tire sealant and compressor kit instructions.

The kit includes:

  1. Tire Sealant Canister
  2. Sealant Canister Inlet Valve
  3. Pressure Gauge
  4. Compressor
  5. Power Plug
  6. Sealant/Air Hose
  7. On/Off Button

Tire Sealant

Read and follow the safe handling instructions on the label adhered to the tire sealant canister (1).

Check the tire sealant expiration date on the tire sealant canister.

The tire sealant canister (1) should be replaced before its expiration date. Replacement tire sealant canisters are available at your local dealer.

There is only enough sealant to seal one tire. After usage, the tire sealant canister must be replaced.

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

When using the tire sealant and compressor kit during cold temperatures, warm the kit in a heated environment for five minutes.

This will help to inflate the tire faster.

If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on the hazard warning flashers. See If a Tire Goes Flat for other important safety warnings.

Do not remove any objects that have penetrated the tire.

1. Remove the tire sealant canister (1) and compressor (4) from its storage location.

See Storing the Tire Sealant and Compressor Kit (With Subwoofer) or Storing the Tire Sealant and Compressor Kit (Without Subwoofer).

2. Remove the sealant/air hose (6) and the power plug (5) from the bottom of the compressor (4).

3. Place the compressor on the ground near the flat tire.

4. Remove the plug from the

4. Remove the plug from the sealant canister inlet valve (2) and from the sealant canister (1).

Screw the sealant canister (1) onto the sealant canister inlet valve (2) without removing the tinfoil from the canister.

5. Remove the valve stem cap from the flat tire by turning it counterclockwise.

Make sure the tire valve stem is positioned close to the ground so the hose will reach it.

6. Remove the protective cap and

6. Remove the protective cap and attach the sealant/air hose (6) to the tire valve stem by turning it clockwise until tight.

7. Plug the power plug (5) into the accessory power outlet in the vehicle. Unplug all items from other accessory power outlets.

Do not pinch the power plug cord in the door or window.

8. Start the vehicle. The vehicle must be running while using the air compressor.

9. Press the on/off button (7) to turn the tire sealant and compressor kit on.

The compressor will inject sealant and air into the tire.

The pressure gauge (3) 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.

10. Inflate the tire to the recommended inflation pressure using the pressure gauge (3). The recommended inflation pressure can be found on the Tire and Loading Information label.

The pressure gauge (3) may read higher than the actual tire pressure while the compressor is on. Turn the compressor off to get an accurate pressure reading. The compressor may be turned on/off until the correct pressure is reached.

Caution: If the recommended pressure cannot be reached after approximately 10 minutes, the vehicle should not be driven farther. The tire is too severely damaged and the tire sealant and compressor kit cannot inflate the tire. Remove the power plug from the accessory power outlet and unscrew the inflating hose from the tire valve.

11. Press the on/off button (7) to turn the tire sealant and compressor kit off.

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

Therefore, Steps 12-14 must be done immediately after Step 11.

Be careful while handling the tire sealant and compressor kit as it could be warm after usage.

12. Unplug the power plug (5) from the accessory power outlet in the vehicle.

13. Turn the sealant/air hose (6) counterclockwise to remove it from the tire valve stem.

14. Replace the tire valve stem cap.

15. Immediately drive the vehicle 8 km (5 mi) but not longer than 10 minutes to distribute the sealant in the tire.

16. Stop at a safe location and check the tire pressure. Refer to Steps 1-10 under "Using the Tire Sealant and Compressor Kit without Sealant to Inflate a Tire (Not Punctured)." If the tire pressure has fallen more than 68 kPa (10 psi) below the recommended inflation pressure, stop driving the vehicle. The tire is too severely damaged and the tire sealant cannot seal the tire.

If the tire pressure has not dropped more than 68 kPa (10 psi) from the recommended inflation pressure, inflate the tire to the recommended inflation pressure by using the compressor to increase the pressure or turn the air release valve counterclockwise at the air filler hose to decrease the pressure.

17. If the flat tire was able to inflate

17. If the flat tire was able to inflate to the recommended inflation pressure, remove the maximum speed label from the sealant canister and place it in a highly visible location.

Do not exceed the speed on this label until the damaged tire is repaired or replaced.

18. The sealant canister cannot be removed from the compressor.

See your dealer to have the canister replaced.

19. Return the sealant/air hose (6) and power plug (5) back to their original storage location.

20. Store the tire sealant and compressor kit in the load compartment.

21. Wipe off any sealant from the wheel, tire, or vehicle.

22. After temporarily sealing a tire using the tire sealant and compressor kit, take the vehicle to an authorized dealer within 161 km (100 mi) of driving to have the tire repaired or replaced.
