If the vehicle has the tire sealant and compressor kit
shown above, follow the operating instructions under
“Tire Sealant and Compressor Kit (Without Selector
Switch).
{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 3‑36.
{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.
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. See Roadside Service
on page 8‑8. Read and follow all of the tire sealant and compressor
kit instructions.

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 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. See Roadside Service on page 8‑8.
If the tire pressure has not dropped more than
68 kPa (10 psi) 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 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 a 161 km (100 miles) of
driving to have the tire repaired or replaced.Using the Tire Sealant and Compressor
Kit without Sealant to Inflate a Tire
