Your vehicle may be equipped with a vehicle stability enhancement system called Stabilitrak®. It is an advanced computer controlled system that assists you with directional control of the vehicle in difficult driving conditions.

Stabilitrak® activates when the computer senses a discrepancy between your 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 direction which you are steering.

When the system activates, a warning light or message may appear on the instrument panel. See your vehicle's owner's manual for more information. You may also hear a noise or feel vibration in the brake pedal. This is normal. Continue to steer the vehicle in the direction you want it to go.
