Controls in detail Useful features To activate, press the SOS button, the Roadside Assistance button • or the Information button ¡, depending on the type of response required. i When a Tele Aid call has been initiated, the audio system or 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 COMAND* navigation system (if engaged) will continue to run. The display in the instrument cluster is available for use, and spoken commands are only available by pressing the RPT button on the COMAND* unit. A pop-up window will appear in the COMAND* 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 Tele Aid Inoperative appears for approximately 10 seconds in the multifunction display. i The SOS button is located in the overhead control panel. The Roadside Assistance button • ( page 266) and the Information button ¡ ( page 267) are located in the center armrest storage/telephone* compartment. ! 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. 263
