Controls in detail Useful features i The SOS button is located in the overhead control panel. The Roadside Assistance button • and the Information button ¡ are located below the center armrest cover. i When a Tele Aid call has been initiated, the audio system or COMAND* System unit is muted and the selected mode (radio, tape or CD) pauses.

The Tele Aid system utilizes the cellular network for communication and the GPS (Global Positioning System) satellites for vehicle location. If either of these signals are unavailable, the Tele Aid system may not function and if this occurs, assistance must be summoned by other means. G If the indicator lamps on the SOS button, on the Roadside Assistance button, and/or on the Information button remain illuminated continuously in red and/or the message Malfunction. Drive to workshop is displayed in the multifunction display after the system self-check, a malfunction in the system has been detected.
