To store the compact spare tire, use
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.
