Therefore, these signals may not last long
enough for the integrated remote control 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 transmitter button ( ;, = or ?) and
hold it down during the following steps until
the setup has been completed
successfully.XAt the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until the frequency signal has been
saved.XIf the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.XContinue with the other programming
steps (see above).
Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R check the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with devices that operate at
frequencies between 280 and 390 MHz.
R replace the batteries in garage door remote
control A. This increases the likelihood of
garage door remote control A sending a
strong and precise signal to the integrated
remote control on the rear-view mirror.
R when programming, hold garage door
remote control A at varying distances and
angles from the transmitter button which
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 there is another garage door remote
control for the same device, perform the
programming steps again using that garage
door opener. Before performing these
steps, make sure that new batteries have
been installed in the garage door remote
control.
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 remote
control 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 ? on
the integrated remote control in the rear-
view mirror that is programmed to operate
the garage door.
Garage door system with fixed code:
indicator lamp : lights up continuously.
Garage door system with rolling code:
indicator lamp : flashes briefly and then
lights up for approximately two seconds.
This is repeated for up to 20 seconds.
i The transmitter will transmit a signal for
as long as the transmitter button is being
pressed. The transmission will be halted
after a maximum of 20 seconds and

GWarning
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle's doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked up.
Care of the exterior
Automatic car washGWarning
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, you must drive particularly
carefully after washing the vehicle until the
brakes have dried.
You can wash the vehicle in an automatic car
wash from the very start.
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. The exterior mirrors could
otherwise be damaged.
! In car washes with a towing mechanism,
make sure that AUTOTRONIC is in
transmission position N, otherwise the
vehicle could be damaged.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (airflow control is turned to
position 0/the à and Á buttons
are switched off).
R the windshield wiper switch is at position
0 .
The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield.
