Tele Aid
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 Tele Aid system
(Tele
matic Alarm Identification on
D
emand)
The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance
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 are available.
The speaker volume of a Tele Aid call can
be adjusted by using the volume control on
the COMAND system headunit or on the
multifunction steering wheel. To raise, turn
the rotary volume control on the COMAND
system headunit clockwise or press
buttonæ on the multifunction steering
wheel. To lower, turn the rotary volume
control on the COMAND system headunit
counterclockwise or press buttonç on
the multifunction steering wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
!The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the Information button¡. Failure
to complete either of these steps will result in a
system that is not activated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).
iThe SOS button is located in the overhead

page 231).
The Roadside Assistance button•
(
page 232) and the Information button¡
(
page 233) are located below the center

!The Tele Aid system utilizes the cellular
network for communication and the GPS
(G

location. If either of these signals are unavail-
able, the Tele Aid system may not function and if
this occurs, assistance must be summoned by
other means.

Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold outer signal transmitter
buttons2 and4 and release them
only when indicator lamp1 begins to
flash after approximately 20 seconds
(do not hold the button for longer than
30 seconds). This procedure 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 transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and
begin directly with step 3.Step 3:Hold end of hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from signal trans-
mitter button (2, 3 or4) to be
programmed, while keeping indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal
transmitter button (2, 3, or4). Do
not release the buttons until step 5 is
completed.
Indicator lamp1 will flash, first slowly
and then rapidly.Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3, or4) and
observe indicator lamp1.
If indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3, or4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
iIndicator lamp1 flashes immediately 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.
iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.
