Driving and Operating 9-37 Electronic Stability Control (ESC) The vehicle has a vehicle stability enhancement system called StabiliTrak. It is an advanced computer controlled system that assists with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the computer senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the intended direction. To turn the system off, press g located on the console to the right of the shifter. Press and release g and the traction control system turns off and the traction control system warning light comes on. Press g again to turn the system back on. For information on turning StabiliTrak off and on, see Electronic Stability Control (ESC) on page 9‑37. Adding non‐GM accessories can affect the vehicle's performance. See Accessories and Modifications on page 10‑3 for more information. When the stability control system activates, the Traction Control System (TCS)/StabiliTrak light flashes on the instrument panel. This also occurs when traction control is activated. A noise might be heard or vibration might be felt in the brake pedal. This is normal. Continue to steer the vehicle in the intended direction. If there is a problem detected with StabiliTrak, the TCS/StabiliTrak light comes on and the system is not operational. See Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light on page 5‑22. Driving should be adjusted accordingly.
