5-62 Service and Appearance Care 12. Unplug the power plug (H) from the accessory power outlet in the vehicle. 13. Turn the sealant/air hose (F) counterclockwise to remove it from the tire valve stem. 14. Replace the tire valve stem cap. 15. Replace the sealant/air hose (F), and the power plug (H) back in their original location. 17. Return the equipment to its original storage location in the vehicle. 18. Immediately drive the vehicle 5 miles (8 km) to distribute the sealant in the tire. 19. 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 a Tire (Not Punctured)." If the tire pressure has fallen more than 10 psi (68 kPa) below the recommended inflation pressure, stop driving the vehicle. The tire is too severely damaged and the tire sealant cannot seal the tire. See Roadside Assistance Program on page 7-6. 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 7-6. 11. Press the on/off button (B) 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 through 18 must be done immediately after Step 11. Be careful while handling the tire sealant and compressor kit as it could be warm after usage. 16. If the flat tire was able to inflate to the recommended inflation pressure, remove the maximum speed label from the sealant canister (E) and place it in a highly visible location. The label is a reminder not to exceed 55 mph (90 km/h) until the damaged tire is repaired or replaced.
