Competitive Driving Mode The driver can select this optional handling mode by pressing the ACTIVE HANDLING button on the console for more than five seconds. A chime will sound and COMPETITIVE DRIVING will be displayed in the DIC. Competitive Driving mode allows the driver to have full control of the rear wheels while the Active Handling System helps steer the vehicle by selective brake application. The instrument cluster light will not be on. The Traction Control System will not be operating. Adjust your driving accordingly. When you press the ACTIVE HANDLING button again, or turn the ignition to ACC, the Active Handling and Traction Control Systems will be on. The TRAC/ACT HNDLG-ON message will be displayed temporarily in the DIC and a chime will be heard. 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. Selective Ride Control You may have a ride control system on your vehicle called Selective Ride Control. The system provides the following performance benefits: Reduced Impact Harshness Improved Road Isolation Improved High-Speed Stability Improved Handling Response Better Control of Body Ride Motions 4-12
