Electronic Stability Control (ESC)/ Traction Control System (TCS) Indicator/Warning Light The Electronic Stability Control (ESC) system or the Traction Control System (TCS) indicator/warning light comes on briefly when the engine is started. If it does not, have the vehicle serviced by the dealer/ retailer. If the system is working normally the indicator light goes off. This light, along with the appropriate Driver Information Center (DIC) messages, indicates when the ESC system and the TCS are working or are disabled. If the light comes on and stays on, the TCS and potentially the ESC system have been disabled. Check the DIC messaging to determine which system is turned off, or not working. If the system is not working, the vehicle needs service. See your dealer/retailer. When the TCS is disabled, wheel spin is not limited. When the ESC system is disabled, the system does not aid in maintaining vehicle directional control. If the light comes on and flashes, the TCS or the ESC system is actively working. When the LOW TRACTION message appears, the system is limiting wheel spin. When the ESC ACTIVE message appears, the system is aiding in maintaining vehicle directional control. See Electronic Stability Control (ESC) on page 5‑6 and Traction Control System (TCS) on page 5‑9 for more information. See DIC Warnings and Messages on page 4‑48 for more information on the messages associated with this light. 4-33
