9-44 Driving and Operating StabiliTrak® System The vehicle has an electronic stability control system called StabiliTrak. It is an advanced computer controlled system that assists the driver with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the computer senses a discrepancy between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to assist the driver with keeping the vehicle on the intended path. When the vehicle is started and begins to move, the system performs several diagnostic checks to insure there are no problems. The system may be heard or felt while it is working. This is normal and does not mean there is a problem with the vehicle. The system should initialize before the vehicle reaches 32 km/h (20 mph). In some cases, it may take approximately two miles of driving before the system initializes. If cruise control is being used when StabiliTrak activates, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 9‑46. If there is a problem detected with StabiliTrak, a SERVICE STAB SYS message displays on the Driver Information Center (DIC). See Ride Control System Messages on page 5‑24 for more information. When this message is displayed, the system is not working. Adjust your driving accordingly. StabiliTrak and Traction Control (TCS) come on automatically whenever the vehicle is started and the systems are reset with The TCS/StabiliTrak button is located on the instrument panel. To turn off TCS, press and release the TCS/StabiliTrak button. The TCS/StabiliTrak Off light comes on in the instrument panel cluster, and TRAC OFF comes on the DIC. To turn TCS back on, press and release the TCS/StabiliTrak button. Adding non-dealer/non-retailer accessories can affect the vehicle's performance. See Accessories and Modifications on page 10‑3.
