garage door can become trapped or struck by
the garage door. There isarisk of injury.
When using the integrated garage door
opener, always make sure that nobody is

gases such as carbonmonoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
The HomeLink®garage door opener
integrated in the rear-view mirror allows you
to operate up to three different door and gate
systems.

on garage doors that:
Rhave safety stop and reverse features and
Rmeet current U.S. federal safety standards
When programming a garage door opener,
park the vehicle outside the garage.
iCertain 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-

Notes on programming the remote
control
Canadianradio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may notlast long
enough for the integrated garage door
opener. The signal is notrecognized during
programming. Comparable with Canadian
law, some U.S.garage door openers also
feature a "break".

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:
RCheck the transmitter frequency of garage
door drive remote control.This can
usually be found 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
280to 433MHz.
RReplace the batteries in garage door
remote control.This increases the
likelihood that garage door remote control
will transmit a strongand precise signal
to the integrated garage door openerinthe
rear-view mirror.
RWhen programming, hold remote control
at varying distances and angles from the
button that you are programming. Try
various angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf 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.
RNote that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button on remote control
again before transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
