StabiliTrak® System Your vehicle is 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 SYS ACTIVE message will be displayed on the Driver Information Center. See DIC Warnings and Messages on page 264. 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 SYS message will be displayed on the Driver Information Center. See DIC Warnings and Messages on page 264. When this message is displayed, the system is not operational. Driving should be adjusted accordingly. StabiliTrak® comes on automatically whenever you start your vehicle. To help assist you with directional control of the vehicle, you should always leave the system on. You can turn StabiliTrak® off if you ever need to through the TC (traction control) on/off button. See Traction Control System (TCS) on page 323. 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 on page 193 or Adaptive Cruise Control on page 197 for more information. 326
