Electronic Stability Control (ESC)/ Traction Control System (TCS) Indicator/Warning Light This light is located in the center of the instrument panel cluster. If this light is on and not flashing, the TCS and potentially the ESC system have been disabled. Check your DIC messaging to determine which feature(s) is no longer functioning and whether it is because of the driver turning off the feature(s), or the system may not be working properly and your vehicle requires service. If the TCS is disabled, wheel spin will not be limited. If the ESC system is disabled, the system will not aid in maintaining vehicle directional control. In either case, adjust your driving accordingly. If the light is on and flashing, the TCS or the ESC system is actively working. Check the DIC messaging for details to determine which system is working. If the LOW TRACTION message appears, the system is limiting wheel spin. If the ESC ACTIVE message appears, the system is aiding in maintaining vehicle directional control. See Electronic Stability Control (ESC) on page 4-10 and Traction Control System (TCS) on page 4-6 for more information. See DIC Warnings and Messages on page 3-43 for more information on the messages associated with this light. For vehicles that have the Electronic Stability Control (ESC) system or the Traction Control System (TCS), this indicator/warning light should come on briefly when the engine is started. If the indicator/warning light does not come on then, have it fixed so it will be ready to warn you if there is a problem. This light, along with the appropriate Driver Information Center (DIC) messages, indicates when the ESC system and the TCS are working or are disabled. 3-33
