If the SERVICE ABS message is being displayed, your Traction Control System and the Active Handling System will also be disabled. The Driver Information Center will scroll three messages: SERVICE ABS, SERVICE TRACTION SYS and SERVICE ACTIVE HNDLG, and the instrument cluster car icon will be illuminated. The driver can acknowledge these messages by pressing the reset button three times. When the service message is displayed the computer controlled systems will not assist the driver and you should have the system repaired as soon as possible. Adjust your driving accordingly. SERVICE ACTIVE HANDLING: If the SERVICE ACTIVE HNDLG message is displayed, there is a problem with your Active Handling System and your vehicle needs service. The instrument cluster light will also be on and a chime will sound. When this message is displayed, the system is not working. Adjust your driving accordingly. SERVICE COLUMN LOCK (Manual Transmission Only): If the system that controls the locking and unlocking of the steering column does not work properly, have the vehicle towed to a dealer for service. SERVICE RIDE CONTROL: This message is used to indicate to the driver that the Selective Ride Control system has detected a malfunction and that the system must be serviced. The SERVICE RIDE CONTROL message will always come on when a failure is detected by the Selective Ride Control system. If a fault is present in the Selective Ride Control system which causes the shocks to be in their full soft condition, the SERVICE RIDE CONTROL, SHOCKS INOPERATIVE and MAXIMUM SPEED 80 MPH (129 km/h) will display together. You will never get a SHOCKS INOPERATIVE and MAXIMUM SPEED 80 MPH (129 km/h) message without a SERVICE RIDE CONTROL message. 3-65
