2007 Cadillac STS Owner's Manual - Page 325

Competitive Driving Mode (STS-V) The driver can select this optional handling mode by pressing the Traction Control button, located near the shift lever, twice within five seconds. Competitive driving mode allows the driver to have control of the power applied to the rear wheels, while the StabiliTrak® system helps steer the vehicle by selective brake application. In competitive mode, the levels at which StabiliTrak® is engaged have been modified to better suit a performance driving environment. When the traction control warning light is on, the Traction Control System will not be operating. Adjust your driving accordingly. When you press the Traction Control button again, the Traction Control System will be on. The traction engaged symbol will be displayed temporarily in the DIC and a chime will be heard. See DIC Warnings and Messages on page 264 for more information. 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 264 for more information. See your dealer for service. 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. 325
