The antitheft alarm is automatically armed or disarmed 
with the remote control or any of your vehicle’s keys by 
locking or unlocking the vehicle.
The antitheft alarm is armed within approximately 
10 seconds after locking the vehicle.
A blinking lamp (1) indicates that the alarm is armed.
Operation:
Once the alarm system has been armed, the exterior 
vehicle lamps will flash and an alarm will sound when 
someone:
•opens a door,
•opens the trunk,
•opens the hood,
•opens the glove box,
•attempts to raise the vehicle.The alarm will last approximately 3 minutes in form of 
flashing exterior lamps. At the same time an alarm will 
sound for 30 seconds. The alarm will stay on even if the 
activating element (a door, for example) is immediately 
closed. If the alarm stays on for more than 20 seconds, 
an emergency call is initiated automatically. See Tele 
Aid on page 130.
Note:
We recommend that you carry the flat key with you and 
keep it in a safe place (e.g. your wallet) so that it is 
always handy. Never leave the f lat key in the vehicle.
When you unlock the driver’s door with the mechanical 
key, the exterior lamps will flash and the alarm will 
sound.

Programming or reprogramming the integrated 
remote control:
1.Turn key in starter switch to position 1 or 2.
2.Hold the end of the hand-held transmitter of the 
d evice you w ish  to train approxim ately 2 to 5 inch es 
(5 cm to 12 cm) away from the surface of the 
integrated remote control located on the inside rear 
view mirror, keeping the indicator lamp in view.
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: 
If, after repeated attempts, you do not successfully 
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”).

Canadian programming:
During programming, your hand-held transmitter may 
automatically stop transmitting. Continue to press and 
hold the integrated remote control transmitter button 
(note steps 2 through 4 in the “Programming” portion) 
while you press and re-press (“cycle”) your hand-held 
transmitter every two seconds until the frequency 
signal has been learned. The indicator lamp will f lash 
slowly and then rapidly after several seconds upon 
successful training.Operation of remote control:
1.Turn key in starter switch to position 1 or 2.
2.Select and press the appropriate button to activate 
the remote controlled device. The integrated remote 
control transmitter continues to send the signal as

Important!
The initial activation of the Tele Aid system may only be 
performed by completing the subscriber agreement and 
placing an acquaintance call using the “SOS” button. 
Failure to complete either of these steps will result in a 
system that is not activated. If the system is not 
activated the indicator lamp in the “SOS” button stays 
on after turning electronic key in starter switch to 
position 2.
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).
(Te l ematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response; 
automatic and manual emergency, roadside assistance 
and information.
The Tele Aid system is operational providing that the 
vehicle’s battery is charged and properly connected, not 
damaged and cellular and GPS coverage is available. To 
activate, press the “SOS” button, the Roadside 
Assistance button or the Information button¡, 
depending on the type of response required.Shortly after the completion of your Acquaintance Call, 
you will receive a user ID and password via first call 
mail. 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 turning the key in steering lock to 
position 2, malfunctions are detected and indicated (the 
indicator lamps in the “SOS” button, the Roadside 
Assistance button and the Information 
button¡ stay on longer than 10 seconds or do not 
come on).
Important!
Always make sure that the indicator lamps in the 
“SOS” button, in the “Roadside Assistance” button and 
in the “Information” button do not remain illuminated

Located below the center armrest cover is the Roadside 
Assistance button. Pressing and holding the 
button (for longer than 2 seconds), will initiate a call to 
a Mercedes-Benz Roadside Assistance dispatcher. The 
button will flash while the call is in progress. The 
Tele Aid system will transmit data generating the 
vehicle identification number, model, color and location 
(subject to availability of cellular and GPS signals).
A voice connection between the Roadside Assistance 
dispatcher and the occupants of the vehicle will be 
established. The nature of the need for assistance can 
then be described. The Mercedes-Benz Roadside assistance dispatcher will 
either dispatch a qualified Mercedes-Benz technician or 
arrange to tow your vehicle to the nearest 
Mercedes-Benz Center. For services such as labor and/
or towing charges may apply. Refer to the Roadside 
Assistance manual for more information. 
These programs are only available in the USA:
•Sign and Drive services: Serv ices su ch as jump sta rt, 
a few gallons of fuel or the replacement of a f lat tire 
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits 
the Mercedes-Benz Roadside Assistance dispatcher 
to download malfunction codes and actual vehicle 
data.
Notes:
The indicator lamp in the Roadside Assistance 
button remains illuminated in red for 
approximately 10 seconds during the system self-check 
after turning key in steering lock to position 2 (together 
with the “SOS” button and the Information

safe location. The Response Center will 
automatically contact local emergency officials 
with the vehicle’s approximate location if they 
receive an automatic “SOS” signal and cannot make 
voice contact with the vehicle occupants.
