GM Service Manual Online
For 1990-2009 cars only

Your vehicle has StabiliTrak. This system helps provide integrated control of systems such as the Antilock Brake System, traction control and engine control. This system automatically controls the brakes and engine to help prevent the vehicle from skidding when cornering on a slippery road surface or turning the steering wheel abruptly.

This system activates when your vehicle speed reaches or exceeds 9 mph (15 km/h), and deactivates when the vehicle speed reduces to below 9 mph (15 km/h).

You may hear a sound in the engine compartment for a few seconds when the engine is started or just after the vehicle begins to move. This means that the system is in the self-check mode, but does not indicate a problem.

The traction control system warning light and the VSC OFF light will come on. To turn the systems back on, press the switch again. If both systems are turned off, they will not turn back on automatically when vehicle speed increases.

If the VSC OFF light flashes, there is a problem in the traction control system or StabiliTrak.
