the way in which you receive this information beforehand. Possible options include text
message, e-mail or an automated call.
The area can be determined as either a circle
or a polygon with a maximum of ten corners.
You can specify up to ten areas simultane-
ously. Different settings are possible for each area.
These settings can be called up under "Own-
ers Online" at http://www.mbusa.com.

tems.
Use the integrated garage door opener only
on garage doors that:
R have safety stop and reverse features and
R meet current U.S. federal safety standards
Once programed, the integrated garage door opener in the rear-view mirror will assume the
function of the garage door system's remote
control. Please also read the operating
instructions for the garage door system.
When programming a garage door opener,
park the vehicle outside the garage. Do not
run the engine while programming.
Certain garage door drives are incompatible
with the integrated garage door opener. If you
have difficulty programing the integrated
garage door opener, contact an authorized
Mercedes-Benz Center.
Alternatively, you can call the following tele-

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Programming Programming buttons
Pay attention to the "Important safety notes"
(Y page 311). Garage door remote control
0083is not inclu-
ded with the integrated garage door opener.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 147).
X Select one of buttons 0044to0085 to use to
control the garage door drive.
X To start programming mode: press and
hold one of buttons 0044to0085 on the inte-
grated garage door opener.
The garage door opener is now in program-
ming mode. After a short time, indicator
lamp 0043lights up yellow.
Indicator lamp 0043lights up yellow as soon
as button 0044,0087or0085 is programmed for
the first time. If the selected button has
already been programmed, indicator lamp
0043will only light up yellow after ten
seconds have elapsed.
X Release button 0044,0087or0085. Indicator
lamp 0043flashes yellow.
X To program the remote control: point
garage door remote control 0083towards
buttons 0044to0085 on the rear-view mirror at
a distance of 2 to 8 inches (5 to 20 cm).
X Press and hold button 0084on remote control
0083 until indicator lamp 0043lights up green.
When indicator lamp 0043lights up green:
programming is finished.
When indicator lamp 0043flashes green: pro-
gramming was successful. The next step is to synchronize the rolling code
(Y page 312).
X Release button 0084on remote control 0083for
the garage door drive system.
If indicator lamp 0043lights up red: repeat the
programing procedure for the correspond-
ing button on the rear-view mirror. When
doing so, vary the distance between remote control 0083and the rear-view mirror.
The required distance between remote
control 0083and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 311).
If the garage door system uses a rolling code,
you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned at different
locations depending on the manufacturer. It
is usually located on the door drive unit on the garage ceiling.
Familiarize yourself with the garage door
