Instruments and Controls If the light does not come on, have the vehicle serviced by the dealer. If the system is working normally, the indicator light turns off. If the light is on while certain DIC messages display, this indicates that the TCS and StabiliTrak systems are not working or are disabled. If the light is on and not flashing, the TCS and potentially the StabiliTrak system have been disabled. Check the DIC messages to determine which feature(s) is no longer functioning and whether it is because of the driver turning off the feature(s), or because the system is not working properly and the vehicle requires service. If the TCS is disabled, wheel spin is not limited. If the StabiliTrak system is disabled, the system does not aid in maintaining directional control of the vehicle. If the indicator/warning light is on and flashing, the TCS or the StabiliTrak system is actively working. See StabiliTrak® System on page 9‑36 and Traction Control System (TCS) on page 9‑35 for more information. See Ride Control System Messages on page 5‑32 for more information on the messages associated with this light. 5-21 If it does not, have the vehicle serviced by the dealer. If the system is working normally, the indicator light goes off. Notice: Driving with the engine coolant temperature warning light on could cause the vehicle to overheat. See Engine Overheating on page 10‑20. The vehicle's engine could be damaged, and it might not be covered by the vehicle warranty. Never drive with the engine coolant temperature warning light on. 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 10‑20. Engine Coolant Temperature Warning Light For eAssist vehicles, this light comes on briefly while starting the vehicle.
