Garage door opener
Important safety notes
The HomeLink ®
garage door opener
integrated in the rear-view mirror allows you
to operate up to three different door and gate
systems.
i Certain garage door drives are
incompatible with the integrated garage
door opener. If you have difficulty
programming the integrated garage door
opener, contact an authorized Mercedes-
Benz Center or call one of the following
telephone hotlines:
R USA: Mercedes-Benz Customer
Assistance Center at
1-800-FOR-MERCedes
R Canada: Customer Service at
1-800-387-0100
GWARNING
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.

Programming the integrated garage
door opener on the rear-view mirror
Programming
GWARNING
Only press the transmitter button on the
integrated garage door opener if there are no
persons or objects present within the sweep
of the garage door. People could otherwise be
injured by the movement of the door.
Integrated garage door opener in the rear-view
mirror (example: Coupe)
Garage door remote control A is not part of
this integrated garage door opener.
i To achieve the best result, insert new
batteries in garage door remote control
A before programming.
XBefore programming for the first time, clear
the memory of the integrated garage door
opener ( Y page 270).XTurn the SmartKey to position 2 in the
ignition lock.XPress and hold one of transmitter
buttons ; to ? on the integrated garage
door opener.
Indicator lamp : starts to flash yellow
after a short period.
i Indicator lamp : flashes yellow
immediately after the transmitter button
has been stored for the first time. If the
transmitter button has already been
programmed, indicator lamp : does not
flash yellow until 10 seconds have elapsed.
XRelease the transmitter button.XPoint transmitter button B of garage door
remote control A towards the transmitter
buttons on the rear-view mirror at a
distance of 2 to 8 inches (5 to 20 cm).
i The distance required between garage
door remote control A and the integrated
garage door opener depends on the system
268FeaturesStowing and features

of the garage door drive. You might require
several attempts. You should test every
position for at least 25 seconds before
trying another position.XPress and hold transmitter button B on
garage door remote control A until
indicator lamp : lights up green.
Programming is complete if indicator
lamp : lights up or flashes green.XRelease transmitter button ;, = or ? on
the integrated garage door opener and the
transmitter button on garage door remote
control B.
If indicator lamp : lights up red:
XRepeat the programming procedure for the
transmitter button. When doing so, vary the
distance between the garage door remote
control 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.
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 You now normally have 30 seconds to
initiate the next step.XPress the previously programmed
transmitter button of the HomeLink ®
integrated garage door opener repeatedly
in succession until the door opens.
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.
These signals may not therefore last long
enough for the integrated garage door opener
to recognize the signal during programming.
Comparable with Canadian law, some U.S.
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:
XPress and hold one of transmitter
buttons ; to ? of the integrated garage
door opener.
Indicator lamp : starts to flash yellow
after a short period.XRelease the transmitter button.XPress transmitter button B of the garage
door remote control and hold for two
seconds, then release for two seconds,
then press again and hold for two seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until indicator lamp : is green.
Repeat the process if indicator lamp :
turns red.XContinue with the other programming
steps (see above).Features269Stowing and featuresZ

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 the transmission frequency of
garage door remote control A (usually
found on the reverse side of the remote
control).
The integrated garage door opener is
compatible with devices that can be
operated with units in a frequency range of
280 to 390 MHz.
R change the batteries in garage door remote
control A. This increases the probability
that garage door remote control A will
send a strong and precise signal to the
integrated garage door opener on the rear-
view mirror.
R when programming, hold garage door
remote control A at different distances
and angles from the transmitter button that
you are programming. Try different angles
at a distance between 2 and 12 inches (5
to 30 cm) or the same angle 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 you perform the steps of the
operation, make sure that there are new
batteries in the garage door remote
control.
R note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press the remote control button again
before it stops transmitting.
R align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.Opening/closing the garage door
Once programmed, the integrated garage
door opener will assume the function of the
garage door system's remote control. Please
also read the operating instructions for the
garage door system.
XTurn the SmartKey to position 2 in the
ignition lock.XPress transmitter button ;, = or ? in the
overhead control panel that you have
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 transmitter button is being
pressed. After a maximum of ten seconds,
transmission is terminated and indicator
lamp : flashes yellow. Press the
transmitter button 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 transmitter buttons ; and ?.
The indicator lamp lights up yellow.XPress and hold transmitter 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.
