when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. Please refer to the

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
manufacturer’s recommended
inflation pressure as shown on the
Tire Label (located on the edge of
driver’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.
(This includes the optional full-sized

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
installed
in this section.
