inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the
light remains on.
■When the spare tire is equipped
The vehicle may become lower when driving with the spare tire compared to when driv-
ing with standard tires.

lowing steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
