Low Tire Pressure Indicator: Service and Repair




After the punctured tire is repaired, adjust the tire inflation pressure to the value on the tire pressure label. Drive the vehicle, and check that the TPMS warning light goes out within 10 minutes after the vehicle speed reaches 19 mph (30 km/h).

The system is not affected by tire rotation.
