malfunction or the service is not cur-
rently active, and may not initiate a call.
Visit your Mercedes-Benz Center and

the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.

Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. SmartKey inside vehicle),
and the reserve key 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 pull the
trunk lid recessed handle for minimum
of 20 seconds until the SOS button is
flashing.
The message
Connecting call
appears 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 select-
ed mode (radio, tape 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 clus-
ter is available for use and spoken com-
mands 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.
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
Connecting call
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 recessed handle was
pulled for more than 20 seconds be-
fore door unlock authorization was re-
ceived by the Response Center, you
must wait 15 minutes before pulling
the trunk lid recessed handle again.
