SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire Pressure Monitor System (TPMS) is not working properly.
The tire pressure light also flashes and then remains on during the same ignition cycle. See Tire Pressure Light.
Several conditions may cause this message to appear. See Tire Pressure Monitor Operation for more information.
If the warning comes on and stays on, there may be a problem with the TPMS. See your dealer.
