I have a 2011 Chevy Impala. It is reading-Service tire monitor system, What does this mean?
In the 2011 Chevrolet Impalas there are tire pressure sensors in the wheels. You can access the tire pressure information on your digital display inside the car along with the fuel mileage, odometer, oil life, etc. Most likely you have a problem with one of those sensors or the computer units that deal with the sensors.
