When this warning message is on, the TRACTION CONTROL OFF message in the DIC will come on to remind you that the system will not limit wheel spin. Adjust your driving accordingly. The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 4-30 and If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-29. To turn the system off, press the traction control button located on the center of the instrument panel. 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 5-3 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®. 4-9 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.
