The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance, and
informationThe Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç or use the volume knob
on your COMAND head unit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.Shortly after the completion of your
Tele Aid acquaintance call, you will receive
a user ID and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock and
more.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using the
Information button¡. Failure to
complete either of these steps will re-
sult in a system that is not activated.
If you have any questions regarding ac-
tivation, please call the Response Cen-
ter at 1-800-756-9018 (in the USA) or

iThe SOS button is located above the in-
terior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest cov-

iThe Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.

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:

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:

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-

devices, for example garage door openers,
gate openers, or other devices compatible
with HomeLink

Warning!
G
Before programming the integrated remote
control to a garage door opener or gate op-
erator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage.
When programming a garage door opener,
the door moves up or down. When program-
ming a gate operator, the gate opens or
closes.
Do not use the integrated remote control
with any garage door opener that lacks safe-
ty stop and reverse features as required by
U.S. federal safety standards (this includes
any garage door opener model manufac-
tured before April 1, 1982). A garage door
that cannot detect an object - signaling the
door to stop and reverse - does not meet
current U.S. federal safety standards.

Programming or reprogramming the in-
tegrated remote control
Step 1:
Switch on the ignition (
page 34).
Step 2:
If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and 4 and release
them only when the indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:
Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to 12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp1 in view.
Step 4:
Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (2, 3
or4). Do not release the buttons until
completing step 5.
The indicator lamp1 on the integrat-
ed remote control will flash, first slowly
and then rapidly.Step 5:
When the indicator lamp 1 flashes
rapidly, release both buttons.
Step 6:
Press and hold the just-trained inte-
grated signal transmitter button and
observe the indicator lamp1.
If the indicator lamp1 stays on con-
stantly, programming is complete and
your device should activate when the
integrated signal transmitter button is
pressed and released.iThe indicator lamp1 flashes the first
time the signal transmitter button is
programmed. If this button has already
been programmed, the indicator lamp
will only start flashing after 20 sec-
onds.

Step 12:
Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (2, 3
or4).
Step 13:
To program the remaining two buttons,
repeat the steps above starting with
step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:
Continue to press and hold the inte-
grated signal transmitter button (2,
3 or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.
