Call priority
If other service calls such as a Roadside
Assistance call or Information call are
active, an Emergency call is still possible.
In this case, the Emergency call will take
priority and override all other active calls.
The indicator lamp in the respective button
flashes until the call is concluded. Emer-
gency calls can only be terminated by a Re-
sponse Center or Customer Assistance
Center representative, whereas Roadside
Assistance and Information calls can also
be terminated by pressing button
t on
the multifunction steering wheel.
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
trunk recessed handle for a minimum
of 20 seconds until the SOS button is
flashing.
The message

ap-
pears in the multifunction display.
As an alternative, you may unlock the vehi-
cle via Internet in the “My Tele Aid” section
of “Owner’s Online”, using the ID and pass-
word (USA only).
The Response Center will then unlock your
vehicle with the remote door unlocking
feature.

When a Tele Aid call has been initiated, the
audio system is muted and the selected mode
(radio or CD) pauses. The mobile phone (if con-
nected) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle at a standstill in a safe location. The multi-
function display in the instrument cluster is
available for use. After the Tele Aid call has end-
ed, the optional mobile phone switches on again.
A PIN entry might be necessary.
i
The remote door unlock feature is available
if the relevant cellular phone network is
available.
The SOS button will flash and the message
Connecting Call
will appear in the multifunc-
tion display to indicate receipt of the door unlock
command.
Once the vehicle is unlocked, a Response Center
specialist may attempt to establish voice contact
with the vehicle occupants.
If the trunk recessed handle was pulled for more
than 20 seconds before door unlock authoriza-
tion was received by the Response Center, you
must wait 15 minutes before pulling the trunk
recessed handle again.
