Chevrolet Sonic Owner's Manual: Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor System (TPMS).
The low tire pressure warning light alerts 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.
The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. 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. Maintain the correct tire pressures.
See Tire Pressure Monitor System.
