Controls in detail Useful features ! 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. i When a Tele Aid call has been initiated, the COMAND System audio is muted and the selected mode (radio, tape or CD) pauses. The optional cellular phone (if installed) and inserted in cradle switches off. If you must use this phone, we recommend that you use it only with the vehicle at a standstill in a safe location. Remove the phone from the cradle and place the call. The navigation* system (if engaged) will continue to run. The multifunction display in the instrument cluster is available for use, and spoken commands are only available by pressing the RPT button on the COMAND System. A pop-up window will appear in the COMAND System display to indicate that a Tele Aid call is in progress. After the Tele Aid call has ended, the optional cellular phone switches on again. A PIN entry might be necessary. System self-check Initially, after switching on ignition, malfunctions are detected and indicated (the indicator lamps in the SOS button, the Roadside Assistance button • and the Information button ¡ stay on longer than 10 seconds or do not come on). The message Malfunction Service Required appears in the multifunction display. Warning! Emergency calls An emergency call is initiated automatically following an accident in which the emergency tensioning devices (ETDs) or air bags deploy. An emergency call can also be initiated manually by opening the cover next to the interior rear view mirror labeled SOS, then briefly pressing the button located under the cover. See ( page 258) for instructions on initiating an emergency call manually. Once the emergency call is in progress, the indicator lamp on the SOS button will begin to flash. The message Connecting Call appears in the multifunction display. When the connection is established, the message Call Connected appears in the multifunction display. All information relevant to the emergency, such as the location of the vehicle (determined by the GPS satellite location system), vehicle model, identification number and color are generated. 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 Service Required is displayed in the multifunction display after the system self-check, a malfunction in the system has been detected. If a malfunction is indicated as outlined above, the system may not operate as expected. Have the system checked at the nearest Mercedes-Benz Center as soon as possible. 257
