StabiliTrak® System The vehicle may have the StabiliTrak system which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions. This is accomplished by selectively applying any one of the vehicle's brakes and reducing engine power. The StabiliTrak system comes on automatically whenever the vehicle is started. The system cannot be turned off. This light will flash when the system is operating. The TCS/StabiliTrak warning light on the instrument panel cluster will flash when the system is operating. See Traction Control System (TCS) Warning Light on page 3-58 and StabiliTrak® Indicator Light on page 3-58 for more information. The system may be heard or felt while it is working. This is normal. The SERVICE STABILITRAK message is displayed and the TCS/StabiliTrak warning light on the instrument panel cluster comes on if there is a problem with the system. When this light and the SERVICE STABILITRAK message are on, the system is not working. Adjust your driving accordingly. Traction Control System (TCS) The vehicle has a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that the front wheels are spinning too much or beginning to lose traction. When this happens, the system works the front brakes and reduces engine power (by closing the throttle and managing engine spark) to limit wheel spin. The STABILITRAK NOT READY message may be displayed in the Driver Information Center (DIC) and the Traction Control System (TCS)/StabiliTrak warning light on the instrument panel cluster comes on after first driving the vehicle and exceeding 19 mph (30 km/h) for 30 seconds. The StabiliTrak system is off until the light has turned off. This could take up to 15 minutes. 4-6
