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. SeeHazard Warning Flashers
on
page 4‑3. See
If a Tire Goes Flat
on page 6‑74for other
important safety warnings.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑94.
2. Unlock the air only hose (F) from the sealant canister (B) by pulling up on the lever.
3. Pull the air only hose (F) from the sealant canister (B).
4. Remove the power plug (C) from the air compressor (A).
5. Place the kit on the ground. Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
6. Remove the tire valve stem cap by turning it counterclockwise.
7. Attach the air only hose (F) onto the tire valve stem and push the lever down to secure it.

8. Plug the power plug (C) into the accessory poweroutlet in the vehicle. Unplug all items from other
accessory power outlets. See Accessory Power
Outlet(s) on page 4‑42.
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.
9. Start the vehicle. The vehicle must be running while using the air compressor.
10. Press the on/off (D) button to turn the compressor on.
The compressor will inflate the tire with air only.
11. Inflate the tire to the recommended inflation pressure using the pressure gauge (E). The
recommended inflation pressure can be found on
the Tire and Loading Information label. See
Inflation - Tire Pressure on page 6‑58. The pressure gauge (E) 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.
12. Press the on/off button (D) to turn the tire sealant and compressor kit off.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.
13. Unplug the power plug (C) from the accessory power outlet in the vehicle.
14. Disconnect the air only hose (F) from the tire valve stem, by turning it counterclockwise, and replace
the tire valve stem cap.
15. Replace the air only hose (F) and the power plug (C) back in its original location.
16. Place the equipment in the original storage location in the vehicle.

If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning flashers. SeeHazard Warning Flashers
on
page 4‑3.
See If a Tire Goes Flat
on page 6‑74for other
important safety warnings.
Do not remove any objects that have penetrated
the tire.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑94.
2. Unwrap the sealant/air hose (F) and the power plug (H).
3. Place the kit on the ground.
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 Accessory Power
Outlet(s) on page 4‑42.
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.
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 inflationpressure using the pressure gauge (C). The
recommended inflation pressure can be found on
the Tire and Loading Information label. See
Inflation - Tire Pressure on page 6‑58.
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
Service on page 8‑8.
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. 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.
16. If the flat tire was ableto inflate to the
recommended inflation
pressure, remove the
maximum speed label
from the sealant
canister (E) 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 miles) to distribute the sealant in the tire.

{WARNING:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a
jack is provided with the vehicle, it is designed
only for changing a flat tire. If it is used for
anything else, you or others could be badly
injured or killed if the vehicle slips off the jack. If a
jack is provided with the vehicle, only use it for
changing a flat tire.
Notice: If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to
your vehicle. Always position the jack so that when
the jack head is raised, it will fit firmly in the notch
located inboard from the rocker molding.
5. Turn the wheel wrench counterclockwise to lower the jack lift head until the jack fits under the
vehicle.
6. Raise the jack by turning the wheel wrenchclockwise until the slots in the jack head fit into the
metal flange located behind the triangle on the
plastic molding as shown.
7. Put the compact spare tire near you.
