The Tele Aid system consists of three
types of response:

automatic and manual emergency


roadside assistance and


information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular 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. The volume can also be
adjusted using the volume knob on your
audio system or 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.System self-check
Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than ten seconds or do not come on). The
message
Tele Aid malfunction. Drive
to workshop
appears in the multifunction
display.
iThe SOS button is located above the
interior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.
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.

Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 251) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting call

appears in the multifunction display and
the audio system is muted. When the
connection is established, the message
Call connected
appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the
vehicle (determined by the GPS satellite
location system), vehicle model, identifica-
tion number and color are generated.A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to
determine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if


it has been activated and is
operational. Activation requires a
subscription for monitoring services,
connection and cellular air time


the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center

above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only
possible if the vehicle is able to receive

Warning!
G
Before programming the integrated remote
control to a garage door opener or gate
operator, 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 programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured 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.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience
difficulties with programming the
transmitter, contact an authorized
Mercedes-Benz Center, or call
Mercedes-Benz Customer Assistance
Center (in the USA only) at
1-800-FOR-MERCedes, or Customer
Service (in Canada) at
1-800-387-0100.
iFor operation in the USA only:
This device complies with Part 15 of
the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any
interference received, including
interference that may cause
undesired operation.
Any unauthorized modification to this
device could void the user’s authority
to operate the equipment.

258 Controls in detailUseful featuresProgramming or reprogramming the
integrated remote control
Step 1:
Switch on ignition (
page 33).
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 and4 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 to12 cm) away from the surface
of the integrated remote control
located 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
integrated remote control will flash,
first slowly and then rapidly.Step 5:

When the indicator lamp1 flashes
rapidly, release both buttons.
Step 6:

Press and hold the just-trained
integrated signal transmitter button
and observe the indicator lamp1.
If the indicator lamp1 stays on
constantly, 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 seconds.
