Instruments and controls Tele Aid Operation Driving Instrument cluster display Practical hints Car care Technical data Index 186 Tele Aid system could not initiate an Information call (e.g. the relevant cellular phone network is not available). The message "INFO - CALL FAILED" appears in the multifunction display. Information calls can be terminated using the ì button on the multifunction steering wheel. Important! If the indicator lamps do not start flashing after pressing one of the buttons or remain illuminated (in red) at any time, the Tele Aid system has detected a fault or the service is not currently active, and may not initiate a call. Visit your Mercedes-Benz Center and have the system checked or contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada) as soon as possible. Upgrade Signals Tele Aid system processes calls using the following priority. • Automatic emergency - First priority • Manual emergency - Second priority • Roadside assistance - Third priority • Information - Fourth priority Should a higher priority call be initiated while you are connected, an upgrade (alternating) tone will be heard, and the appropriate indicator lamp will flash. If certain information such as vehicle identification number or customer information is not available, the operator may need to retransmit. During this time you will hear a chirp and voice contact will be interrupted. Voice contact will resume once the retransmission is completed. Once a call is concluded, a chirp will be heard and the appropriate indicator lamp will stop flashing. The COMAND system operation will resume (only vehicles with COMAND).
