The Active Handling System is a computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle's brakes.

The ACTIVE HANDLING message will come on when the system is operating. See DIC Warnings and Messages for more information. The system may be heard or felt while it is working. This is normal.

The SERVICE ACTIVE HANDLING SYSTEM message will be displayed, the instrument cluster light will come on, and a sound will be heard if there is a problem with the system.

See DIC Warnings and Messages for more information.

When this light and the SERVICE ACTIVE HANDLING SYSTEM message are on, the system is not operational. Adjust your driving accordingly.

The Active Handling System comes on automatically whenever the vehicle is started. To help maintain directional control of the vehicle, the system should always be left on. The system can be turned off needed. If the Active Handling System is turned off, the Traction Control System will also be turned off. Adjust your driving accordingly.

To turn the system off, press the ACTIVE HANDLING button on the console for five seconds. The system can be turned back on at any time by pressing the button. The DIC will display the appropriate message when the button is pushed.

If the Tire Pressure Monitor (TPM) system detects a flat tire and the Driver Information Center (DIC) displays TIRE FLAT, or if the TPM system is malfunctioning and the DIC displays SERVICE TIRE MONITOR, the Active Handling System will be affected as follows:

    • The Active Handling System cannot be turned off by the driver.
    • If the Active Handling System is off, it will be turned on automatically.
    • Competitive Driving Mode is unavailable.
    • The Active Handling System will feel different in aiding and maintaining directional control.

Competitive Driving Mode

The driver can select this optional handling mode by pressing the ACTIVE HANDLING button on the console quickly two times. COMPETITIVE DRIVING MODE 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 maintain directional control of the vehicle by selective brake application. This involves less intervention than with both the Active Handling System and Traction Control Systems on. The Traction Control System will not be operating. Adjust your driving accordingly.

This light will be on when the vehicle is in the Competitive Driving Mode.

When the ACTIVE HANDLING button is pressed again, the Active Handling and Traction Control Systems will be on. The TRACTION SYSTEM AND ACTIVE HANDLING-ON message will be displayed briefly in the DIC and a chime will be heard.

Notice: When traction control is turned off, or Competitive Driving Mode is active, it is possible to lose traction. If you attempt to shift with the drive wheels spinning with a loss of traction, it is possible to cause damage to the transmission. Do not attempt to shift when the drive wheels do not have traction. Damage caused by misuse of the vehicle is not covered. See the warranty book for additional information.
