8. Make sure there is a proper connection between the tire valve stem and the sealant filling hose by looking at the air pressure gage. If there is not a pressure reading while the compressor is running, the connection between the inflator kit and the tire is bad. Check the attachment between the sealant filling hose and the tire valve stem. 9. Inflate the tire up to the recommended inflation pressure, found on the Tire and Loading Information label located on the vehicle's center pillar (B-pillar) below the vehicle's door latch, using the air pressure gage on the top of the unit as a guide. The pressure gage reading is slightly high while the compressor is on. Turn the compressor off to get an accurate pressure reading. Notice: If the recommended pressure cannot be reached after 15 minutes, the vehicle should not be driven. The tire is too severely damaged and cannot be inflated or sealed with the tire sealant and compressor kit. 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 7-6. 10. Move the inflator kit switch to the O (off) position once the correct tire pressure is obtained. 11. Turn off the engine. 12. Unplug the air compressor accessory plug from the accessory power outlet in the vehicle. 13. Disconnect the sealant filling hose from the tire valve stem, by turning it counterclockwise, and replace the tire valve stem cap. Be careful when handling the tire inflator components as they may be hot after usage. 14. Wrap the sealant filling hose around the air compressor channel to stow it in its original location. 5-91
