(approximately 50 km / h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
!The initial activation of the Tele Aid
system may only be performed by
completing the subscriber agreement
and placing an acquaintance call using
the ¡ button. Failure to complete
either of these steps will result in a sys-
tem that is not activated.
If you have any questions regarding ac-
tivation, please call the Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).

Call priority
If other service calls such as a Roadside
Assistance call or Information call are ac-
tive, an Emergency call is still possible. In
this case, the Emergency call will take pri-
ority and override all other active calls. Response Center was established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
Call failed
ap-
pears in the multifunction display.
Information calls can be terminated us-
ing the tbutton on the multifunc-
tion steering wheel or the respective
button for ending a telephone call on
the COMAND headunit.
!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
malfunction or the service is currently
not active, and may not initiate a call.
Visit an authorized Mercedes-Benz
Center and have the system checked
or contact the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.

248 Controls in detailUseful featuresProgramming the integrated remote
control
Step 1:
Switch on the ignition (
page 36).Step 2:
If you have previously programmed an
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 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 transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.Step 3:
Hold the end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping the indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press the hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
The indicator lamp1 will flash, first
slowly and then rapidly.
When programming a garage door opener, it
is advised to park outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and
possible death.

Step 5:
After the indicator lamp1 changes
from a slow to a rapidly flashing light,
release the hand-held remote control
button and the signal transmitter but-
ton.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe the indicator lamp1.If the 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 re-
leased.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn” or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
operator’s manual.
iThe indicator lamp1 flashes immedi-
ately the first time the signal transmit-
ter button is programmed. If this button
has already been programmed, the in-
dicator lamp will only start flashing af-
ter 20 seconds.
iIf the 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.

pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:
To program the remaining two signal
transmitter 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
integrated signal transmitter to pick up the
signal 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
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Press and hold the signal transmitter
button (2, 3 or4). Do not release
this button until it has been successful-
ly trained.
iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.

Switch on the ignition (
page 36).
Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.Erasing the integrated remote control
memory
Switch on the ignition (
page 36).
Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.
Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.
While performing step 3, hold the
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
iIf you sell your vehicle, erase the codes
of all three channels.
