StabiliTrak®/Traction Control System (TCS) Warning Light The StabiliTrak and Traction Control System (TCS) indicator/warning light comes on briefly while starting the engine. See StabiliTrak® System on page 4-6, Traction Control System (TCS) on page 4-8 and DIC Warnings and Messages on page 3-38 for more information. Engine Coolant Temperature Gage This gage shows the engine coolant temperature. If it does not, have the vehicle serviced by your dealer/ retailer. If the system is working normally the indicator light then goes off. The light flashes while the StabiliTrak system and TCS are working to assist the driver with directional control of the vehicle in difficult driving conditions. If the StabiliTrak system and TCS light comes on and stays on while driving and a TRACTION FAULT or SERVICE STAB SYS message displays on the DIC, the vehicle needs service. The light also comes on steady when the StabiliTrak system and/or TCS are turned off. The DIC also displays a TRAC OFF and/or STAB SYS OFF message. If the TCS is off, wheel spin is not limited. If the StabiliTrak system is off, the system does not assist the driver with directional control of the vehicle. The light turns off when the TCS and StabiliTrak system are turned back on. If the gage pointer is near the top of the gage, the engine is too hot. It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull the vehicle off the road, stop the vehicle and turn off the engine as soon as possible. See Engine Overheating on page 5-32 for more information. 3-29
