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

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.
