The TCS and StabiliTrak® light will flash when the system is limiting wheel spin. To turn the system off or on, press and release this button located in front of the shift lever. The system may be heard or felt while it is working, but this is normal. See Traction Control System (TCS) Warning Light on page 3-58 for more information. If the vehicle is in cruise control when TCS begins to limit wheel spin, the cruise control will automatically disengage. The cruise control may be re-engaged when road conditions allow. See Cruise Control on page 3-16. The SERVICE TRACTION CONTROL message in the DIC and the TCS/StabiliTrak warning light comes on if there is a problem with the traction control system. See DIC Warnings and Messages on page 3-73. When this light and the SERVICE TRACTION CONTROL message are on, the system will not limit wheel spin. Adjust your driving accordingly. TCS automatically comes on whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, always leave the system turned on. TCS can be turned off if needed. The system can be turned on or off at any time by pressing the TCS button. The DIC will display TRACTION CONTROL OFF when the button is pressed, and part of the traction control system is disabled. The vehicle will still have brake-traction control, but will not be able to use the engine speed management system. System noises may be heard as a result of the brake-traction control working. If the controller detects excessive wheel spin in this mode, the TCS/StabiliTrak light may blink. It is recommended to leave the system on for normal driving conditions, but it may be necessary to turn the system off if the vehicle is stuck in sand, mud, ice or snow, and you want to "rock" the vehicle to attempt to free it. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-18. 4-7
