The TCS 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 TCS system off if you ever need to. To turn the system off, press the button located on the console. You can turn the system on or off at any time by pressing the ACTIVE HANDLING button. The DIC will display the appropriate message when you push the button. Active Handling System The Active Handling System is a computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle's brakes. When you first start your vehicle during cold winter weather and begin to drive away, the message ACTIVE HANDLING WARMING UP may be displayed in the DIC. This is normal. You can acknowledge this message by pressing the RESET button. The Active Handling System performance is affected until the message, ACTIVE HANDLING READY, is displayed in the DIC. The ACTIVE HANDLING CALIBRATING message may be displayed in the DIC and the instrument panel cluster light will be on after exceeding 18 mph (30 km/h) for 10 seconds. The Active Handling System is off until the ACTIVE HANDLING READY message is displayed. This could take up to 15 minutes. The ACTIVE HANDLING message will come on when the system is operating. See DIC Warnings and Messages on page 3-53 for more information. You may also feel or hear the system working. This is normal. Adding non-GM accessories can affect your vehicle's performance.
