Important safety notes
GWARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Refueling137Driving and parkingZ

! If the coolant temperature is too high a
display message is shown.
If the coolant temperature rises above
248 ‡(120 †), do not drive any further as
this could damage the engine.
Tachometer
The red band in the tachometer indicates the
engine's overrevving range.
! Do not drive in the overrevving range, as
this could damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
The outside temperature display is in the
multifunction display ( Y page 184).
GWARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Changes in the outside temperature are
displayed after a short delay.
Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Cruise control ( Y page 146) activated:
The segments light up from the stored speed
to the maximum speed.
DISTRONIC PLUS ( Y page 148) activated:
One or two segments in the set speed range
light up.
DISTRONIC PLUS detects a vehicle in front:
The segments between the speed of the
vehicle in front and the stored speed light up.

programmed, indicator lamp : does not
flash yellow until 10 seconds have elapsed.
XRelease 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 8 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 25 seconds before
trying another position.
XPress and hold transmitter button B on
garage door remote control A until
indicator lamp : lights up green.
Programming is complete if indicator
lamp : lights up or flashes green.XRelease transmitter button ;, = or ? on
the integrated garage door opener and the
transmitter button on garage door remote
control B.
If indicator lamp : lights up red:
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 indicator lamp flashes green after
successful programming, the garage door
system is operating on a rolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronizing the rolling code
Your vehicle must be within range 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 synchronization.XTurn the SmartKey to position 2 in the
ignition lock.XPress the programming button of the door
or gate drive (see the door or gate drive
operating instructions, e.g. under
"Programming of additional remote
controls").
i You now normally have 30 seconds to
initiate the next step.
XPress the previously programmed
transmitter button of the HomeLink ®
integrated garage door opener repeatedly
in succession until the door opens.
The rolling code synchronization is then
complete.
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.
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:
258FeaturesStowing and features

buttons ; to ? of the integrated garage
door opener.
Indicator lamp : starts to flash yellow
after a short period.XRelease the transmitter button.XPress transmitter button B of the garage
door remote control and hold for two
seconds, then release for two seconds,
then press again and hold for two seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until indicator lamp : is green.
Repeat the process if indicator lamp :
turns red.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).
The integrated garage door opener is
compatible with devices that can be
operated with units in a frequency range of
280 to 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 when programming, hold garage door
remote control A at different distances
and angles from the transmitter button that
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 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 note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press the remote control button again
before it stops transmitting.
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 garage
door opener 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:

i
The transmitter will transmit a signal for
as long as the transmitter button is being
pressed. After a maximum of ten seconds,
transmission is terminated and indicator
lamp : flashes yellow. Press the
transmitter button again, if necessary.
