{WARNING
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, seeEngine
Exhaust on page 9‑21.
{WARNING
Over-inflating 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 inflate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{WARNING
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.

Vehicle Care 10-59
The tire sealant and compressor
can be used to temporarily seal
punctures up to ¼ inch (6 mm) in
the tread area of the tire. It can also
be used to inflate an under
inflated 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 Assistance
Program on page 13‑5.
Read and follow all of the tire
sealant and compressor kit
instructions. This vehicle may have one of the
following tire sealant and
compressor kits. The kit includes:
A. Selector Switch (Sealant/Air or
Air Only)
B. On/Off Button
C. Pressure Gage
D. Pressure Deflation Button (If equipped)
E. Tire Sealant Canister
F. Sealant/Air Hose (Clear)
G. Air Only Hose (Black)
H. Power Plug

10-60 Vehicle Care
Tire Sealant
Read and follow the safe handling
instructions on the label adhered to
the sealant canister.
Check the tire sealant expiration
date on the sealant canister.
The sealant canister should be
replaced before its expiration date.
Replacement sealant canisters are
available at your local dealer/
retailer. See“Removal and
Installation of the Sealant Canister”
following.
There is only enough sealant to seal
one tire. After usage, the sealant
canister and sealant/air hose
assembly must be replaced. See
“Removal and Installation of the
Sealant Canister” following.
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 5 minutes.
This will help to inflate the tire
faster.
Always do a safety check first. See
If a Tire Goes Flat
on page 10‑56.
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 10‑65.

Vehicle Care 10-61
2. Unwrap the sealant/air hose (F)and the power plug (H).
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 (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 Power Outlets
on
page 5‑8.
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 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
gage (C). The recommended
inflation pressure can be found on the Tire and Loading
Information label. See
Tire
Pressure on page 10‑43.
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 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 (B) toturn 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 able to inflate
to the recommended inflation
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 Inflate a Tire (Not
Punctured).”
If the tire pressure has fallen
more than 10 psi (68 kPa)
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 on page 13‑5.
If the tire pressure has not
dropped more than 10 psi
(68 kPa) from the
recommended inflation
pressure, 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 (E) and sealant/air
hose (F) assembly at a local
dealer/retailer or in accordance
with local state codes and
practices.
