KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO func-
tion and a detachable Start/Stop button.
The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehicle.
When you insert the Start/Stop button into the ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in succession corresponds to the different key
positions in the ignition lock. This is only 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 vehicle.
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 75)
Do not keep the KEYLESS-GO 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 functionality of KEYLESS-GO.
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 button
on the front door (Y page 81), you can continue
to start the engine with the Start/Stop button.
The engine can be switched off while the vehicle is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.

Heating Auxiliary heating departure time
G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
Only vehicles with auxiliary heating have this
function.
In the Heating Heating submenu, you can select a
stored departure time or change a departure
time.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by the departure time. When the departure time isreached, the auxiliary heating continues to heat
for a further five minutes and then switches off. The auxiliary heating adopts the THERMATIC orTHERMOTRONIC temperature setting.
You can switch off the auxiliary heating by using
the remote control or the auxiliary heating but-
ton on the centre console.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.

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.

Several attempts may be required. You
should test every position for at least
25 seconds before trying another position.
Synchronising the rolling code
Observe the "Important safety notes"
(Y page 277).
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 programming but-
ton may be placed at different locations depend- ing 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 "Program-
ming of additional remote controls", before car-
rying out the following steps.
Your vehicle must be within range of the garage
door or gate opener drive. Make sure that nei-
ther 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 132).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to initiate
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 com- plete.
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 fre-
quency 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 likelihood that
garage door remote control Awill 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 but-
ton which you are programming. Try various
angles at a distance between 5and 20cm or
at the same angle but at varying distances.
R If there is another remote control for the same
garage door drive, perform the programming
steps again using this remote control. Before
performing these steps, make sure that new
batteries have been fitted in garage door drive remote control A.
R Note that some remote controls transmit only
for a limited period (the indicator lamp on theremote control goes out). Press button Bon
remote control Aagain before transmission
ends.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening or 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.
X Turn the key to position 2in the ignition lock
(Y page 132).
X Press button ;,=or? which you have
programmed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp :lights up green.

The transmitter will transmit a signal for as
long as the button is pressed. The transmis-
sion is halted after a maximum of ten seconds
and indicator lamp :lights up yellow.
X Press button ;,=or? again if necessary.
