
The compact spare tire (if equipped)

The compact spare tire is identified by the label "TEMPORARY USE

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. 633)

When using the compact spare tire (if equipped)
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.

If you have a flat front tire on a road covered with snow or ice (vehicles with
a compact spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires:
STEP 1
Replace a rear tire with the compact spare tire.
STEP 2
Replace the flat front tire with the tire removed from the rear of the
vehicle.
STEP 3
Fit tire chains to the front tires.

After completing the tire change (vehicles with tire pressure warning sys-
tem)
The tire pressure warning system must be reset. (P. 499)
