If you press and hold the TC button for five seconds, the Stabilitrak® and Traction Control systems will turn off. Press the TC button again to turn Stabilitrak® and Traction Control back on. For more information, see Stabilitrak® System on page 4-11. Limited-Slip Rear Axle Your limited-slip rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. Competitive Driving Mode The driver can select this optional handling mode by pressing the Traction Control button on the steering wheel twice within five seconds. COMPETITIVE DRIVING will be displayed in the DIC. Competitive driving mode allows the driver to have control of the power applied to the rear wheels, while the Stabilitrak® system helps steer the vehicle by selective brake application. In competitive mode, the levels at which Stabilitrak® is engaged have been modified to better suit a performance driving environment. When the instrument cluster light is on, the Traction Control System will not be operating. Adjust your driving accordingly. When you press the Traction Control button again, or turn the ignition to ACC, the Traction Control System will be on. The traction engaged symbol will be displayed temporarily in the DIC and a chime will be heard. Stabilitrak® System Your vehicle may be equipped with a vehicle stability enhancement system called Stabilitrak®. It is an advanced computer controlled system that assists you with directional control of the vehicle in difficult driving conditions. Stabilitrak® activates when the computer senses a discrepancy between your intended path and the direction the vehicle is actually traveling. Stabilitrak® selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the direction which you are steering. When the system activates, a Stability System Engaged message will be displayed on the Driver Information Center. See DIC Warnings and Messages on page 3-65. You may also hear a noise or feel vibration in the brake pedal. This is normal. Continue to steer the vehicle in the direction you want it to go. 4-11
