To restore the full functionality of the tire pressure monitoring system,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, see Changing tires with a TPMS in
this section.

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

manufacturer’s recommended pressure
as shown on the Tire Label (located
on the edge of driver’s door or the

for at least two minutes over 20 mph
(32 km/h) before the light turns off.
