20 seconds.XContinue to hold 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 12 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
of the garage door drive. You might require
several attempts. You should test every
position for at least 20 seconds before
trying another position.
XPress and hold transmitter button B on
garage door remote control A until
indicator lamp : flashes rapidly.
Programming was successful if indicator
lamp : flashes rapidly.XRelease transmitter button ;, = or ? on
the integrated garage door opener and
transmitter button B on garage door
remote control A.
If indicator lamp : goes out after
approximately 20 seconds and did not flash
rapidly before this:
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 garage door system works with a
rolling code, you must synchronize the
integrated garage door opener on the rear-
view mirror with the receiver of the garage
door system after programming.
You will find further information in the
garage door opening system's operating
instructions, e.g. the sections on
"Synchronizing the transmitter" or
"Registering a new transmitter". You can
also call the hotline mentioned above.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals a few seconds after broadcasting.
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 transmitter button ;, = or ? and
hold it down during the following steps until
the setup has been completed
successfully.XAdditionally, press transmitter button B
on the garage door remote control and hold
it for two seconds, then release for two
seconds, then press again and hold for two
seconds.XRepeat this sequence of steps on
transmitter button B remote control of the
garage door until the frequency signal has
been learned.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 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).
Features275Stowing and featuresZ

The integrated garage door opener is
compatible with devices that operate at
frequencies between 280 and 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 while programming, hold garage door
remote control A at different distances
and angles from the transmitter button that
you are programming. Try different angles
at distances between 2 and 12 inches (5 to
30 cm) or the same angle at different
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 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 ? 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. The transmission will be halted
after a maximum of 10 seconds, and
indicator lamp : will flash yellow. Press
the transmitter button again, if necessary.

Calibrating the compass
XMake sure that there is sufficient space for
you to drive in a circle without impeding the
remaining traffic.
In order to calibrate the compass correctly,
observe the following points:
R calibrate the compass in the open and not
in the vicinity of steel constructions or high-
voltage transmission lines.
R switch off electrical consumers, for
example, the climate control, windshield
wipers or rear window defroster.
R close all doors and the trunk lid.
XSwitch the ignition on.XPress and hold button =(Y page 277) for
approximately six seconds until the
C symbol appears in compass display ;
( Y page 277).XDrive a full circle at approximately 3 mph

Once the calibration has been successfully
completed, the current direction appears in
compass display ;(Y page 277).
Floormat on the driver's side
GWARNING
Whenever you are using a floormat, make sure
there is enough clearance and that the
floormat is securely fastened.
The floormat should always be securely
fastened using the fastening equipment.
Before driving off, check that the floormat is
securely in place and adjust it if necessary. A
loose floormat could slip and hinder proper
functioning of the pedals.
Do not place several floormats on top of each
other as this may impair pedal movement.XSlide the seat backwards.XTo install: place the floormat in the
footwell.XPress studs : onto retainers ;.XTo remove: pull the floormat off
retainers ;.XRemove the floormat.278FeaturesStowing and features
