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 pull the
tailgate recessed handle 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 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 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 multifunction display in the in-
strument cluster is available for use,
and spoken commands are only avail-
able by pressing the RPT button on the
COMAND unit. A pop-up window will
appear in the COMAND display to indi-
cate 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 Re-
sponse Center specialist will attempt
to establish voice contact with the ve-
hicle occupants.
If the tailgate 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 tailgate recessed handle again.
