WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves
R never cover the vents or ventilation grilles

the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 85)
Do not keep the key:
R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the but- ton on the front door (Y page 91), you can
continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the
Start/Stop button for three seconds. This
function operates independently of the ECO

Important safety notes G
WARNING
When you operate or program the garage door with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

a distance of 5 to 20 cm.
X Press and hold button Bon remote control
A until indicator lamp :lights up green.
When indicator lamp :lights up green:
programming is finished.
When indicator lamp :flashes green: pro-
gramming was successful. The next step is
to synchronise the rolling code
(Y page 331).
X Release button Bof remote control Aof
the garage door drive.
If indicator lamp :lights up red: repeat the
programming process for the correspond-
ing button on the rear-view mirror. When
doing so, vary the distance between remote control Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts may be required.
You should test every position for at least
25 second sbefore trying another position.
Synchronising the rolling code
Observe the "Important safety notes"
(Y page 330).
If the garage door system uses a rolling code,
you will also have to synchronise the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be placed at different loca-
tions depending on the manufacturer. It is
usually located on the door drive unit on the
garage ceiling.
Familiarise yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within range of the
garage door or gate opener drive. Make sure
that neither your vehicle nor any persons/ objects are present within the sweep of the
door or gate.
X Turn the key to position 2in the ignition
lock (Y page 161).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
X Get into the vehicle.
X Press previously programmed button ;,
= or? of the integrated garage door
opener until the door closes.
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: R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
R Replace the batteries in garage door
remote control A. This increases the like-
lihood 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 which you are programming. Try var- ious angles at a distance between 5and
30 cm or at the same angle but at varying
distances.
R If there is another remote control for the
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 garage door drive remote control
