Controls in detail Useful features i When a Tele Aid call has been initiated, the audio system or the COMAND* system audio is muted and the selected mode (radio or CD) pauses. The optional cellular phone (if installed) switches off. If you must use this phone, the vehicle must be parked. Disconnect the coiled cord 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. Remote door unlock In case you have locked your vehicle unintentionally (e.g. SmartKey inside vehicle), and the reserve SmartKey is not handy: Contact the Mercedes-Benz Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada). You will be asked to provide your password which you provided when you completed the subscriber agreement. Then return to your vehicle and press the trunk lid button for a minimum of 20 seconds until the SOS button is flashing. The message CALL CONNECTED appears in the multifunction display. As an alternative, you may unlock the vehicle via Internet using the ID and password sent to you shortly after the completion of your acquaintance call. The Response Center will then unlock your vehicle with the remote door unlocking feature. i The remote door unlock feature is available if the relevant cellular phone network is available. The SOS button will flash and the message CALL CONNECTED will appear in the multifunction display to indicate receipt of the door unlock command. Once the vehicle is unlocked, a Response Center specialist will attempt to establish voice contact with the vehicle occupants. If the trunk lid button was pressed for more than 20 seconds before door unlock authorization was received by the Response Center, you must wait 15 minutes before pressing the trunk lid button again. 248
