If the indicator lamp flashes green after
successful programming, the garage door
system is using a rolling code. After pro-
gramming, you must synchronise the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronising the rolling code
Your vehicle must be within reach 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 synchronisation.
Turn the key to position 2 in the ignition
X
lock.
Press the programming button of the door
X
or gate drive (see the door or gate drive
operating instructions, e.g. under "Pro-
gramming of additional remote controls").
i
Usually, you now have 30 seconds to ini-
tiate the next step.
Press the previously programmed button of
X
the integrated HomeLink
opener repeatedly until the door starts to
move.
The rolling code synchronisation is then
complete.
Problems when programming
If you have problems when programming the
integrated garage door opener, please note
the following:
check the transmitter frequency of garage
R
door remote control A (this can usually be
found on the rear of the remote control).
change the batteries in garage door remote
R
control A. This increases the likelihood
that garage door remote control A will
send a strong and precise signal to the
integrated remote control in the rear-view
mirror.
when programming, hold garage door
R
remote control A at different distances
and angles from the transmitter button that
you are programming. Try various angles at
a distance of between 5 and 30 cm or the
same angle but varying distances.
if there is another remote control for the
R
same garage door drive, perform the pro-
gramming steps again using this remote
control. Before performing these steps,
make sure that new batteries have been
fitted in the garage door drive remote con-
trol.
note that some remote controls transmit
R
only for a limited period (the indicator lamp
on the remote control goes out). Press the
button on the remote control again before
transmission ends.
align the aerial cable of the garage door
R
opener unit. This can improve signal recep-
tion/transmission.
