For 1990-2009 cars only

The Stabilitrak® system helps provide integrated control of the systems such as anti-lock 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 will activate when your vehicle speed reaches or exceeds 9 mph (15 km/h), and will deactivate 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 malfunction.

If the vehicle is going to skid during driving, the traction control system warning light will blink and an alarm will sound intermittently. Adjust your driving accordingly.
