Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor System (TPMS).
The TPMS warning light alerts you to a significant loss in pressure of one of the vehicle's tires. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. See Vehicle Load Limits . The warning light will remain on until the tire pressure is corrected.
During cooler conditions, the low tire pressure warning light may appear when the vehicle is first started and then turn off. This may be an early indicator that the tire pressures are getting low and the tires need to be inflated to the proper pressure.
The TPMS does not replace normal monthly tire maintenance. It is the driver’s responsibility to maintain correct tire pressures.
