equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.

the shorter mounting bolt. 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 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. Keep the spare tire and its
wheel together.
Caution
Tire chains will not fit the compact
spare. Using them can damage the
vehicle and the chains. Do not use
tire chains on the compact spare.
Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly.
See
Tire Pressure 0274 and Vehicle
Load Limits 0176 for information
regarding proper tire inflation and
loading the vehicle. For instructions
on how to remove, install, or store a
spare tire, see Tire Changing0295. After installing the spare tire on the
vehicle, stop as soon as possible and
check that the spare is correctly
inflated. The spare tire is made to
perform well at speeds up to 112 km/h
(70 mph) at the recommended
inflation pressure, so you can finish
your trip.
Have the damaged or flat road tire
repaired or replaced and installed
back onto the vehicle as soon as
possible so the spare tire will be
available in case it is needed again. Do
not mix tires and wheels of different
sizes, because they will not fit. Keep
the spare tire and its wheel together.
