10-62 Vehicle Care 7. Start the vehicle. The vehicle must be running while using the air compressor. 8. Turn the selector switch (A) counterclockwise to the Sealant + Air position. 9. Press the on/off (B) button to turn the tire sealant and compressor kit on. The compressor will inject sealant and air into the tire. The pressure gauge (C) 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 (C). The recommended inflation pressure can be found on the Tire and Loading Information label. See Tire Pressure on page 10‑43. The pressure gauge (C) 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. Notice: If the recommended pressure cannot be reached after approximately 25 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. See Roadside Assistance Program on page 13‑6. 2. Unwrap the sealant/air hose (F) and the power plug (H). 3. Place the kit on the ground. Make sure the tire valve stem is positioned close to the ground so the hose will reach it. 4. Remove the valve stem cap from the flat tire by turning it counterclockwise. 5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it clockwise until it is tight. 6. Plug the power plug (H) into the accessory power outlet in the vehicle. Unplug all items from other accessory power outlets. See Power Outlets on page 5‑8. If the vehicle has an accessory power outlet, do not use the cigarette lighter. If the vehicle only has a cigarette lighter, use the cigarette lighter. Do not pinch the power plug cord in the door or window.
