When using the compact spare tire
As the compact spare tire is not equipped
with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare
tire will not be indicated by the tire pressure
warning system. Also, if you replace the
compact spare tire after the tire pressure
warning light comes on, the light remains
on.
■ When the compact spare tire is
equipped
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires.
■
If you have a flat rear tire on a road cov-
ered with snow or ice (vehicles with
front and rear tires of the same size)
Install the compact spare tire on one of the
front wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the rear
tires:
1 Replace a front tire with the compact
spare tire.
2 Replace the flat rear tire with the tire
removed from the front of the vehicle.
3 Fit tire chains to the rear tires.

Installing the compact spare tire
Failure to follow these precautions could

injury.
