gauge (4). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. SeeTire
Pressure 0271.
The pressure gauge (4) 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.
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 0334. 11. Press the on/off button (1) 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 12–18 must be
done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
12. Unplug the power plug (7) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (6) counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Return the sealant/air hose (6) and the power plug (7) back in
their original locations.
16. 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.
17. Return the equipment to its original storage location in the
vehicle.
18. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire.
19. Stop at a safe location and check the tire pressure. Refer
to Steps 1–11 under “Using the
Tire Sealant and Compressor
Kit without Sealant to Inflate a
Tire (Not Punctured).”

Vehicle Care 289
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.
SeeRoadside Assistance
Program 0334.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, use the
compressor kit to inflate the tire
to the recommended inflation
pressure.
20. Wipe off any sealant from the wheel, tire, and vehicle.
21. Dispose of the used sealant canister and sealant/air hose
(6) assembly at a local dealer
or in accordance with local
state codes and practices.
22. Replace it with a new canister available from your dealer.
23. 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.
Using the Tire Sealant and
Compressor Kit without
Sealant to Inflate a Tire (Not
Punctured)
To use the air compressor to inflate
a tire with air only and not sealant:
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See
Hazard
Warning Flashers 0151. See
If a Tire Goes Flat 0284 for
other important safety warnings.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor
Kit 0291.
2. Unwrap the air only hose (5) and the power plug (7).
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 tire valve stem cap from the flat tire by turning
it counterclockwise.
5. Attach the air only hose (5) onto the tire valve stem by
turning it clockwise until it is
tight.
6. Plug the power plug (7) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.

pressure using the pressure
gauge (4). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0271. The pressure gauge (4) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached. If the tire is inflated
higher than the recommended
pressure, press the pressure
relief button (3), if equipped,
until the proper pressure
reading is reached. This option
is only functional when using
the air only hose (5).
11. Press the on/off button (1) to turn the tire sealant and
