Make sure tires are at the proper pres-

chapter. After inflating your tires to the
manufacturer's recommended 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 turns off.
Repair the damaged road wheel and tire
assembly and reinstall it on the vehicle
to restore system function. For a
description on how the system functions,
see When your temporary spare tire
is installed in this section.
If the tires are properly inflated and the
spare tire is not in use but the light
remains on, contact your authorized
dealer as soon as possible.
On vehicles with different front and rear
