Customer Action Required
1. Check your tire pressure to ensure tires are
properly inflated; refer to Inflating your tires
in this chapter.
2. After inflating your tires to the manufactur-
er's recommended inflation pressure as shown
on the Tire Label (located on the edge of driv-
er's door or the B-Pillar), the vehicle must be
driven for at least two minutes over 20 mph
(32 km/h) before the light will turn OFF.
Your temporary spare tire is in use. Repair the
damaged road wheel/tire and reinstall it on the
vehicle to restore system functionality. For a
description on how the system functions, refer
to When your temporary spare tire is in-
stalled in this section.
If your tires are properly inflated and your
spare tire is not in use and the light remains
ON, contact your authorized dealer as soon as
possible.
