The indicator/warning light flashes while the StabiliTrak or TCS system is working to control the vehicle on a low traction surface. If the TCS warning light comes on and stays on while driving, the vehicle needs service. The light comes on when the TCS and the StabiliTrak system is turned off. If the TCS is off, wheel spin is not limited. If the StabiliTrak system is off, the system does not assist in controlling the vehicle. Turn on the TCS and the StabiliTrak system and the warning light turns off. See StabiliTrak® System on page 4-6 and Traction Control System (TCS) on page 4-7 for more information United States 3-29 Engine Coolant Temperature Gage StabiliTrak /Traction Control System (TCS) Warning Light ® Canada This gage shows the engine coolant temperature.

See Engine Overheating on page 5-27 for more information. The StabiliTrak system or the Traction Control System (TCS) indicator/warning light comes on briefly while starting the engine. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light will then go off.
