VEHICLE DYNAMIC CONTROL (VDC) SYSTEM (if so equipped) ● Tire type and condition of tires may also affect braking effectiveness. ● When replacing tires, install the specified size of tires on all four wheels. ● When installing a spare tire, make sure it is the proper size and type as specified on the Tire and Loading Information label. For tire placard location information, refer to "Tire and Loading Information label" in the "Technical and consumer information" section of this manual. ● Refer to "Wheels and tires" in the "Maintenance and do-it-yourself" section of this manual. When accelerating or driving on slippery surfaces, the tires may spin or slide. With the Vehicle Dynamic Control (VDC) system, sensors detect these movements and control the braking and engine output to help improve vehicle stability. ● When the vehicle dynamic control (VDC) system is operating, the slip indicator in the instrument panel blinks. ● When only the traction control system (TCS) portion of the vehicle dynamic control system is operating, the slip indicator will also blink. ● If the slip indicator blinks, the road conditions are slippery. Be sure to adjust your speed and driving to these conditions. See "Slip indicator light", and "Vehicle dynamic control off indicator light" in the "Instruments and controls" section. ● Indicator light If malfunction occurs in the system, the and indicator lights come on in the instrument panel. As long as these warning lights are on, the traction control function is canceled. The VDC system uses an Active Brake Limited Slip (ABLS) system to improve vehicle traction. The ABLS system works when one of the driving wheels is spinning on a slippery surface. The ABLS system brakes the spinning wheel which distributes the driving power to the other drive wheel. If the vehicle is operated with the vehicle dynamic control system off using the VDC OFF switch, all VDC and TCS functions will be turned off. The ABLS system and ABS will still operate with the VDC system OFF. If the ABLS system is activated, the slip indicator light will blink and you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal. While the VDC system is operating, you may feel a pulsation in the brake pedal and hear a noise or vibration from under the hood. This is normal and indicates that the VDC system is working properly. The computer has a built in diagnostic feature that tests the system each time you start the engine and move the vehicle forward or in reverse at a slow speed. When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indication of a malfunction. Starting and driving 5-29
