When trouble arises
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE ONLY” on
the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire. ( P. 7 1 2 )
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve and
transmitter, 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 wi th the compact spare tire compared to
when driving with standard tires.
■If you have a flat front tire on a road co vered with snow or ice (vehicles with a com-
pact spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the
following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.
