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 STABILITY CONTROL ACTIVE message will be displayed on the Driver Information Center (DIC). See DIC Warnings and Messages . 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.

If there is a problem detected with StabiliTrak®, a SERVICE STABILITY SYSTEM message will be displayed on the Driver Information Center (DIC). See DIC Warnings and Messages . When this message is displayed, the system is not operational. Driving should be adjusted accordingly.

If your vehicle is in cruise control when the StabiliTrak® activates, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may reengage the cruise control. See Cruise Control for more information.
