{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 Exhaust0220.
{Warning
Overinflating 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 or 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 6 mm
(0.25 in) in the tread area of the tire. It can
also be used to inflate an underinflated 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
Assistance Program 0368.
Read and follow all of the tire sealant and
compressor kit instructions. The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose

canisters are available at your local dealer.
There is only enough sealant to seal one
tire. After usage, the tire sealant canister
must be replaced.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
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.
SeeHazard Warning Flashers 0135.
See If a Tire Goes Flat 0319 for other
important safety warnings.

Compact Spare Tire
{Warning
Driving with more than one compact
spare tire at a time could result in loss of
braking and handling. This could lead to a
crash and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare tire, it
was fully inflated when new; however, it
can lose air over time. Check the inflation
pressure regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check that the
spare tire is correctly inflated after being
installed on the vehicle. The compact spare
tire is designed for temporary use only. The vehicle will perform differently with the
spare tire installed and it is recommended
that the vehicle speed be limited to 80 km/h
(50 mph). To conserve the tread of the spare
tire, have the standard tire repaired or
replaced as soon as convenient and return
the spare tire to the storage area.
When using a compact spare tire, the AWD
(if equipped), ABS, and Traction Control
systems may engage until the spare tire is
recognized by the vehicle, especially on
slippery roads. Adjust driving to reduce
possible wheel slip.
Caution
When the compact spare is installed, do
not take the vehicle through an
automatic car wash with guide rails. The
compact spare can get caught on the rails
which can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on other
vehicles.
Do not mix the compact spare tire or wheel
with other wheels or tires. They will not fit.
