3. Using both hands, simultaneously push the hand-
held transmitter button and the desired integrated 
remote control button. Do not release the buttons 
until completing step 4.
4. The indicator lamp on the integrated remote control 
will flash, first slowly and then rapidly. When the 
indicator lamp flashes rapidly, both buttons may be 
released (the rapid flashing lamp indicates 
successful programming of the new frequency 
signal). To program the remaining two buttons, 
follow steps 1 through 4.
Note:

program the integrated remote control device to learn 
the signal of the hand-held transmitter, the garage door 
opener could be equipped with the “rolling code 
feature”.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 of this text. (A second person may make the 
following training procedures quicker and easier.)
1. 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. If 
there is difficulty locating the transmitting button, 
reference to garage door opener operator’s manual. 
2. Press “training” button on the garage door opener 
motor head unit (which activated the “training 
light”).
Note:
Following step 2, there are 30 seconds to initiate 
step 3.

Notes:
The indicator lamp in the Information button¡ 
remains illuminated in red for approx. 10 seconds 
during the system self-check after turning electronic 
key in starter switch to position 2 (together with the 
“SOS” button and the Roadside Assistance button).
See system self-check on page 234 when the indicator 
lamp does not light up in red or stays on longer than 
approximately 10 seconds.
If the indicator lamp in the Information button¡ is 
illuminated continuously and there was no voice 
connection to the Response Center established, then the 
Tele Aid system could not initiate an Information call 
(e.g. the relevant cellular phone network is not 
available). The message “INFO – CALL FAILED” appears 
in the multifunction display.
Information calls can be terminated using the 
ìbutton on the multifunction steering wheel.Important!
If the indicator lamps do not start flashing after 
pressing one of the buttons or remain illuminated (in 
red) at any time, the Tele Aid system has detected a fault 
or the service is not currently active, and may not 
initiate a call. 
Visit your 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.
