When You Believe Your System Is Not Operating Properly

when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. See the following chart for
information concerning your tire pressure monitoring system:

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.
