Driving The AdvanceTrac௢ on/off control button allows the driver to control the availability of the Traction Control௢ and AdvanceTrac௢ system. This is independent of the ABS function, which can NOT be switched off by the driver. The AdvanceTrac௢ system status is indicated by a "TRAC ACTIVE" indicator light in the instrument cluster that will illuminate when the system is active. If a failure is detected, the "TRAC OFF" indicator light will stay ON, vehicles with a message center (if equipped) will also display the warning "CHECK ADVANCETRAC", have the system serviced immediately. The AdvanceTrac௢ system continually monitors and checks all sensors used in improving the stability of the vehicle. Some drivers may notice a slight movement of the brake pedal when the system checks itself. During AdvanceTrac௢ operation you may experience the following: • A rumble or clicking sound much like ABS or Traction Control௢ • A slight deceleration or a reduction in the acceleration of the vehicle • The "TRAC ACTIVE" indicator light will illuminate • If your foot is on the brake pedal, you will feel a vibration in the pedal much like ABS. As with any vehicle equipped with four-wheel ABS, do not pump the brakes, but instead, press firmly on the pedal. • If your foot is not on the brake, the brake pedal will move to apply higher brake forces. You may also hear a whoosh of air from under the instrument panel during this kind of braking. All these conditions are normal during AdvanceTrac௢ operation. Aggressive driving in any road conditions can cause you to lose control of your vehicle increasing the risk of severe personal injury or property damage. The occurrence of an AdvanceTrac௢ event is an indication that at least some of the tires have exceeded their ability to grip the road and that you may lose control of the vehicle. If you experience a severe road event, SLOW DOWN. 172
