Remote door unlock
In case you have locked your vehicle unin-
tentionally (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 pass-
word 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
ap-
pears in the multifunction display.
As an alternative, you may unlock the vehi-
cle 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.
iWhen 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 press-
ing 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.
iThe remote door unlock feature is avail-
able if the relevant cellular phone net-
work is available.
The SOS button will flash and the mes-
sage
CALL CONNECTED
will appear in
the multifunction display to indicate re-
ceipt of the door unlock command.
Once the vehicle is unlocked, a
Response Center specialist will at-
tempt to establish voice contact with
the vehicle occupants.
If the trunk lid button was pressed for
more than 20 seconds before door un-
lock authorization was received by the
Response Center, you must wait
15 minutes before pressing the trunk
lid button again.
