The 2007 Chevrolet Impala is equipped with a Tire Pressure Monitor System (TPMS) that uses sensors to monitor tire pressure levels. The Impala’s display on the instrument panel shows a low tire pressure alert if it senses that one or more of the tires is below the recommended air pressure. The display shows the current pressure of each tire. If the reading becomes inaccurate, it is necessary to reset the tire monitor system for the tires, so that a proper reading will be displayed.
- Set the parking brake. Turn the ignition switch to the “RUN” position with the engine off.
