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.
