{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-36.
{CAUTION:
Over-inating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor kit
instructions and inate the tire to its recommended
pressure. Do not exceed the recommended
pressure.
{CAUTION:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to
store a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to
14inch (6 mm) in the
tread area of the tire. It can also be used to inate
an under inated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire is
too severely damaged for the tire sealant and
compressor kit to be effective. SeeRoadside Service on
page 7-7.
Read and follow all of the tire sealant and compressor
kit instructions.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate 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 5 minutes. This will help to inate the tire faster.Always do a safety check rst. SeeIf a Tire Goes Flat
on page 5-84. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from
it’s storage location. SeeTire Sealant and
Compressor Kit Storage on page 5-104.
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 at 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. SeeAccessory Power
Outlet(s) on page 3-46.
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 gage (C) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is
completelydispersed into the tire, the pressure will
quickly drop and start to rise again as the tire
inates with air only.
10. Inate the tire to the recommended ination pressure
using the pressure gage (C). The recommended
ination pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-64.
The pressure gage (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 inate the tire. Remove the
power plug from the accessory power outlet
and unscrew the inating hose from the tire valve.
SeeRoadside Service on page 7-7.
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.
5-100

16. If the at tire was
able to inate to the
recommended ination
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.
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
Inate a Tire (Not Punctured).”If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Service on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and
sealant/air hose (F) assembly at a local
dealer/retailer or in accordance with local state
codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.
