Low Tire Pressure Indicator: Description and Operation

This light comes on when the tire pressure monitoring system detects that one or more of your tires is significantly under-inflated. This light will also come on for a few seconds and then go off when you turn the ignition to ON. This indicates that the tire pressure monitoring system is functioning properly.






When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possible and inflate them to the proper pressure as indicated on the vehicle's tire information placard. Driving on the significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life and may affect the vehicle's handling and stopping ability. Each tire should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and the owner's manual. If the tire pressure monitoring system warning light does not illuminate when the ignition key is turned to the "ON" position, have the system inspected by an authorized service facility.

If the warning light flashes while driving, check to see whether the warning light goes off after a few minutes of driving. If it goes off during driving, there is no problem. However, if the warning light does not go off, or if it flashes again when the vehicle is driven, have the vehicle inspected by an authorized service facility.
