Notes on programing the remote control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programing. Comparable with Canadian law,
some U.S. garage door openers also feature
a "break".
Proceed as follows:
R if you live in Canada
R if you have difficulties programing the
garage door opener (regardless of where
you live) when using the programing steps
X Press and hold one of buttons 0044to0085 on
the integrated garage door opener.

X Repeat this sequence on button 0084of
remote control 0083until indicator lamp 0043
lights up green.
When indicator lamp 0043lights up green:
programing is finished. When indicator lamp
0043flashes green:
programing was successful. The next step
is to synchronize the rolling code.
X Release button 0084of remote control 0083of
the garage door drive.
If indicator lamp 0043blinks red: repeat the
programing process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote
control 0083and the rear-view mirror.
i The required distance between remote
control 0083and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be
necessary. You should test every position
for at least 25 seconds before trying
another position.
Problems when programing
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
R Check the transmitter frequency used by
garage door drive remote control 0083and
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280 to 433 MHz.
R Replace the batteries in garage door
remote control 0083. This increases the
likelihood that garage door remote control
0083 will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
R When programing, hold remote control 0083
at varying distances and angles from the
button that you are programing. Try various
angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances. Features

If another remote control for the same
garage door drive is available, repeat the
same programing steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control 0083.
R Note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button 0084on remote control
0083 again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening/closing the garage door After it has been programed, the integrated
garage door opener performs the function of

R the transmission is locked in position P
after disconnecting the battery. The

You can then no longer move the vehicle.
The battery and the cover of the positive

during operation.
Comply with safety precautions and take
protective measures when handling
batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the
battery. Avoid creating sparks. Battery acid is caustic. Avoid
contact with skin, eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and
faceguard.
Rinse any acid spills immediately
with clear water. Contact a
physician if necessary. Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes–Benz
recommends that you only use batteries that
have been tested and approved for your
vehicle by Mercedes-Benz. These batteries
have greater impact resistance and as a result
there is no risk of acid burns to occupants
when a battery is damaged in an accident. In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery
disconnected at a qualified specialist
workshop. You can also charge the battery
with a charger recommended by Mercedes-
Benz. Contact a qualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for a lengthy period. Consult a qualified
specialist workshop if you wish to leave your
vehicle parked for a long period of time.

cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
R You may only jump-start the vehicle when the engine and exhaust system are cold.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Only jump-start from batteries with a 12 V voltage rating.
R Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the battery slightly.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
R the jumper cables cannot come into contact with parts which can move when the engine
