9-70 Vehicle Service and Care 10. Turn the compressor off by pushing the On/Off button (A) to the I (off) position. The pressure gage (G) reads slightly high while the compressor is on. Turn the compressor off to get an accurate 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 15 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 on page 12-6. The tire is not sealed and will continue to leak air until the vehicle is driven and the sealant is distributed in the tire. Steps 11 through 19 must be done right after Step 10. Be careful while handling the tire sealant and compressor kit as they could be hot after usage. 11. Unplug the air compressor accessory plug (B) from the accessory power outlet in the vehicle. 12. Turn the sealant/air hose (E) counterclockwise to remove. 13. Replace the tire valve stem cap. 14. Stow the sealant/air hose (E) and air compressor accessory plug (B) in their original locations. 8. Check the air pressure gage (G). If there is not a pressure reading while the compressor is running, check for leaks at the connection between the tire valve stem and the sealant/air hose (E). 9. Inflate the tire to the recommended inflation pressure, found on the Tire and Loading Information label. See Inflation - Tire Pressure on page 9-49. The pressure gage (G) will initially read high while the compressor injects the sealant into the tire. Once the sealant injection is complete, the pressure will quickly drop. It will start to rise again as the tire inflates with air.
