CHANGING THE TIRES
If you get a flat tire while driving,
do not apply the brake heavily.
Instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.
Spare tire information
Your vehicle is equipped with a
spare tire that may be used as a
spare or a regular tire. The spare
tire is not equipped with wheel
trim. The wheel trim from the
original wheel/tire may be used on
the spare.
If your vehicle is equipped with
4WD or AWD, a spare tire of a
different size than the road
tires should not be used. Such
