{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 and 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 (U.S. and Canada) on
page 13‑7 orRoadside Assistance
Program (Mexico) on page 13‑10.
Read and follow all of the tire
sealant and compressor kit
instructions. The kit includes:
A. On/Off Button
B. Selector Switch (Sealant/Air or
Air Only)
C. Pressure Relief Button
D. Pressure Gauge
E. Air Only Hose (Black)
F. Sealant/Air Hose (Clear)

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 9‑30.

the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant

The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.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 the
vehicle was new; however, it can
lose air after a 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 installing the spare on
the vehicle. The compact spare is
designed to perform well at speeds
up to 105 km/h (65 mph) for
distances up to 5 000 km (3,000 mi),
so a trip can be completed and the
full-size tire repaired or replaced when possible. However, the
compact spare tire will last longer
and be in good shape if it is
replaced as soon as possible.
Notice:
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. Keep the spare tire
and its wheel together.
Notice: Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.
