If the system is limiting wheel spin when you press the button, the TRACTION CONTROL ACTIVE message will go off, but the system will not turn off until there is no longer a current need to limit wheel spin. The TRACTION CONTROL OFF message will come on to remind you the system is off. You can turn the system back on at any time by pressing the button again. The traction control system warning message should go off. Adding non-GM accessories can affect your vehicle's performance. See Accessories and Modifications on page 400 for more information. StabiliTrak® System Your vehicle may be equipped with StabiliTrak® which combines anti-lock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions. When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If the system fails to turn on or activate, the SERVICE STABILITY SYSTEM message will be displayed on the Driver Information Center (DIC). If the vehicle has gone through heavy acceleration or braking or multiple turns during the first two miles of driving after starting your vehicle, the STABILITY CONTROL OFF message may appear on the DIC. If this is the case, your vehicle does not need servicing. You will need to turn the vehicle off and then restart it to initialize StabiliTrak®. If either message appears on the DIC, and your vehicle has not gone through hard acceleration, braking or multiple turns in the first two miles of driving, your vehicle should be taken in for service. The STABILITY CONTROL ACTIVE message will appear on the DIC only when the system is both on and activated. It means that an advanced computer-controlled system has come on to help your vehicle continue to go in the direction in which you are steering. StabiliTrak® activates when the computer senses that your vehicle is just starting to spin, as it might if you hit a patch of ice or other slippery spot on the road. When the system activates, you may hear a noise or feel a vibration in the brake pedal. This is normal. 355
