Magnetic Ride Control Your vehicle may have Magnetic Ride Control that automatically adjusts the ride of your vehicle. Automatic ride control is achieved through a computer used to control and monitor the suspension system. The controller receives input from various sensors to determine the proper system response. If the controller detects a problem within the system, the DIC will display a SERVICE SUSPENSION SYS message. See DIC Warnings and Messages on page 3-80 for more information. See your dealer for service. StabiliTrak® System Your 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. If your all-wheel-drive vehicle has the optional enhanced vehicle stability control system called Active Steering with Enhanced StabiliTrak®, see Enhanced StabiliTrak® on page 4-9. StabiliTrak® activates when the computer senses a discrepancy 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 direction which you are steering. When the system activates, a STABILITY SYS ACTIVE message will be displayed on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-80. 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. Limited-Slip Rear Axle Your limited-slip rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. 4-8
