Instruments and Controls If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 5‑21. 5-23 StabiliTrak® Indicator Light The light flashes if the system is active and is working to assist the driver with directional control of the vehicle in difficult driving conditions.
