malfunction. BAS (Brake Assist), COLLISION PREVENTION
ASSIST, ESP

ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the

brake hard, for example.
The steerability and braking characteristics may be severely
affected. The braking distance in an emergency braking situation
can increase.

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 garage door
opener. The signal is not recognized during
programming. 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 programming the
garage door opener (regardless of where
you live) when using the programming
steps
X Press and hold one of buttons ; to ? on
the integrated garage door opener.
After a short
time, indicator lamp : lights
up yellow.
X Release the button.
Indicator lamp : flashes yellow.
X Press button B of garage door remote
control A for two
seconds, then release it
for two seconds.
X Press button B again for two seconds.
X Repeat this sequence on button B of
remote control A until indicator lamp :
lights up green.
If indicator lamp : turns red, repeat the
process.
X Continue with the other programming
steps (see above).
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
transmitter
frequency of garage
door drive remote control A. 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 433
MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood that garage door remote control
A
will transmit 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 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.
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 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 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.
X
Turn the SmartKey to position 2 in the
ignition lock.
