GM Service Manual Online
For 1990-2009 cars only

The Active Handling System light will come on briefly as you start the engine. If the light does not come on then, have it fixed so it will be ready to warn you if there is a problem. The light will also come on while the system warms up and the ACT HNDLING WARMING UP message will be displayed in the Driver Information Center (DIC).


Object Number: 807060  Size: A2

If the light stays on or comes on while you are driving, a chime sounds and a SERVICE ACTIVE HNDLG message appears on the DIC, there is a problem with your Active Handling System and your vehicle needs service.

The driver can acknowledge this message by pressing the RESET button. When the SERVICE ACTIVE HNDLG message is displayed, the Active Handling System will not assist you in controlling the vehicle. You should have the system serviced as soon as possible. Adjust your driving accordingly.

When the system is working, you will see the ACTIVE HANDLING message displayed in the DIC. You may also feel or hear the system working. This is normal.

If the driver turns off the Active Handling System by pressing the button on the console, the Active Handling System light will come on, a chime will sound, and the TRAC/ACT HNDLG OFF message will be displayed in the DIC. The Traction Control System will also be turned off. See DIC Warnings and Messages for more information.

If the Active Handling System and the Traction Control System are off, pressing the console button momentarily will turn both systems on. The DIC will display the TRAC/ACT HNDLG ON message, the instrument cluster light will be off, and a chime will sound. See DIC Warnings and Messages for more information.
