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.
