5-22 Instruments and Controls If the light is on and not flashing, the TCS, and potentially the StabiliTrak system have been disabled. A DIC message may display. Check the DIC messages to determine which feature(s) is no longer functioning and whether the vehicle requires service. If the indicator/warning light is on and flashing, the TCS and/or the StabiliTrak system is actively working. See StabiliTrak System on page 9‑36 and Traction Control System (TCS) on page 9‑34. ® Engine Coolant Temperature Warning Light The engine coolant temperature warning light comes on when the engine has overheated. If this happens, pull over and turn off the engine as soon as possible. See Engine Overheating on page 10‑22. Tire Pressure Light This light comes on briefly while starting the vehicle. If it does not, have the vehicle serviced by the dealer. If the system is working normally the indicator light goes off. Notice: The engine coolant temperature warning light indicates that the vehicle has overheated. Driving with this light on can damage the engine and it may not be covered by the vehicle warranty. See Engine Overheating on page 10‑22. For vehicles with the Tire Pressure Monitor System (TPMS), this light comes on briefly when the engine is started. It provides information about tire pressures and the TPMS.
