336 Vehicle Care
Caution
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
0 369.
11. Press the on/off button (4) 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 20 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 (7) from the
accessory power outlet in the vehicle.
13. Turn the sealant/air hose (2)
counterclockwise to remove it from the
tire valve stem.
14. Replace the tire valve stem cap.
15. Turn the air only hose (8)
counterclockwise to remove it from the
tire sealant canister inlet valve (1).
16. Replace the tire sealant canister inlet
valve (1) cap.
17. Return the air only hose (8) and power
plug (7) back to their original storage
location.
18. 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.
19. Return the equipment to its original
storage location in the vehicle.
20. Immediately drive the vehicle 8 km
(5 mi) to distribute the sealant in
the tire.
21. 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.
See Roadside Assistance Program 0 369.
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.
22. Wipe off any sealant from the wheel,
tire, or vehicle.
23. Dispose of the used tire sealant
canister (3) at a local dealer or in
accordance with local state codes and
practices.
24. Replace it with a new canister available
from your dealer.
25. 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.
