XPress and hold button B on remote control
A until indicator lamp : lights up green.
The programming has been successful if
indicator lamp : lights up or flashes
green.XRelease button ;, = or ? on the
integrated garage door opener and button
B on garage door remote control A.
If indicator lamp : lights up red:
XRepeat the programming operation for the
corresponding button on the rear-view
mirror. When doing so, vary the distance
between remote control A and the rear-
view mirror.
i If the indicator lamp flashes green after
successful programming, the garage door
system is operating on a rolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronizing the rolling code
Your vehicle must be within range of the
garage or gate opener drive. Make sure that
neither your vehicle nor any persons/objects
are present within the sweep of the door or
gate.
Observe the safety notes when performing
the rolling code synchronization
( Y page 212).
XTurn the SmartKey to position 2 in the
ignition lock.XPress the programming button of the door
or gate drive (see the door or gate drive
operating instructions, e.g. under
"Programming of additional remote
controls").
i Usually, you now have 30seconds to
initiate the next step.
XPress the previously programmed
button ;, = or ? of the integratedgarage door opener repeatedly until the
door starts to move.
The rolling code synchronization is then
complete.
Notes on programming 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 remote control. The
signal is not recognized during programming.
Comparable with Canadian law, some U.S.
garage door openers are designed to "time-
out" in the same manner.
Proceed as follows:
R if you live in Canada.
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps.
XPress and hold one of the buttons ;
to ? on the integrated garage door
opener.
Indicator lamp : starts to flash yellow
after a short period.XRelease the switch.XPress button B of garage door remote
control A for two seconds, then release it
for two seconds.XPress button B again for two seconds.XRepeat this sequence on button B of
remote control A until indicator lamp :
lights up green.
Repeat the process if indicator lamp :
turns red.XContinue with the other programming
steps (see above).214FeaturesStowage and features

Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check remote control frequency of garage
door drive remote control A. This is
usually located on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280 to 390 MHz.
R Change the batteries in garage door remote
control A. This increases the likelihood
that garage door remote control A will
send a strong and precise signal to the
integrated garage door opener in the rear-
view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button which you are programming. Try
various angles at a distance of between 2
to 12 inches (5 to 30 cm) or at the same
angle but at varying distances.
R if another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control A.
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 B on remote control
A 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 programmed, the integrated
garage door opener performs the function of
the garage door system remote control.
Please also read the operating instructions
for the garage door system.XTurn the SmartKey to position 2 in the
ignition lock.XPress one of the buttons ;, = or ?;
whichever one is programmed to operate
the garage door.
Garage door system with a fixed code:
indicator lamp : lights up green.
Garage door system with a rolling code:
indicator lamp : flashes green.
i
The transmitter will transmit a signal for
as long as the button is pressed. The
transmission is halted after a maximum of
ten seconds and indicator lamp : flashes
yellow. Press button ;, = or ? again if
necessary.
Clearing the memory of the integrated
garage door opener on the rear-view
mirror
XTurn the SmartKey to position 2 in the
ignition lock.XPress buttons ; and ?.
The indicator lamp lights up yellow.XPress and hold buttons ; and ? until the
indicator lamp turns green.
i Make sure that you clear the memory of
the integrated garage door opener before
selling the vehicle.
Charge maintenance socket
The battery may drain if the vehicle is left
stationary for long periods. In this case,
Mercedes-Benz recommends attaching the
trickle charger to the charge maintenance
socket.
The charge maintenance socket is designed
solely for connecting a trickle charger. A
trickle charger can be obtained from an
authorized Mercedes-Benz Center, for
example.
