Chevrolet Sonic Owner's Manual: Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmit the tire pressure readings to a receiver located in the vehicle.
When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster. 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 low tire pressure warning light comes on at each ignition cycle until the tires are inflated to the correct inflation pressure.
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 could be an early indicator that the air pressure is getting low and must be inflated to the proper pressure. A Tire and Loading Information label shows the size of the original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits , for an example of the Tire and Loading Information label and its location. Also see Tire Pressure.
The TPMS can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection , Tire Rotation and Tires.
Caution
Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use only the GM approved tire sealant available through your dealer or included in the vehicle.
Factory-installed Tire Inflator Kits use a GM-approved liquid tire sealant. Using non-approved tire sealants could damage the TPMS sensors. See Tire Sealant and Compressor Kit for information regarding the inflator kit materials and instructions.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check
tire pressure levels. The TPMS sensors monitor the air pressure in your tires and
transmit tire pressure readings ...
TPMS Malfunction Light
The TPMS will not function properly if one or more of the TPMS sensors are missing
or inoperable. When the system detects a malfunction, the low tire warning light
flashes for about one minute and ...
