Using the Tire Sealant and
Compressor Kit to Temporarily
Seal and Inflate a
Punctured Tire
Follow the directions closely for
correct sealant usage.
When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire
faster.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 on page 6-4.
See If a Tire Goes Flat on
page 10-63 for 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 Storing the Tire
Sealant and Compressor Kit on
page 10-72.
2. Unwrap the sealant/air hose (6) 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 valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (6)
onto the tire valve stem. Turn 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.
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 (2) clockwise to the Sealant + Air
position.

9. Press the on/off button (1) toturn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (4) 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 (4). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10-50.
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 on
page 13-5. 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.
