Your vehicle may have a traction control system that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power to limit wheel spin.

This light will come on when your traction control system is limiting wheel spin. You may feel or hear the system working, but this is normal.

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, ice or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out .

The traction control system can be turned off by pressing the traction control button, located on the instrument panel above the audio system.

The traction control system can be activated again by pressing the traction control button.

If the system is limiting wheel spin when you press the button, the traction control off light will appear on the instrument panel cluster. The system will not turn off until there is no longer a current need to limit wheel spin. You can turn the system back on at any time by pressing the button again. If the light does not come on, you may not have traction control and your vehicle should be serviced by a dealer.

Adding non-GM accessories can affect your vehicle's performance. See Accessories and Modifications for more information.
