Problem
Possible causes/consequences and
M
MSolutions The indicator lamp over
the ¿ button
flashes three times or
remains off. The cool-
ing with air dehumidifi-
cation function cannot
be activated. The cooling with air dehumidification function has been deactiva-

X Visit aqualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is
maintained automatically at
aconstant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi- cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
deactivate the "Cooling with air-dehumidifi-
cation" function only briefly.

Activating or deactivating the auxiliary
heating or auxiliary ventilation via
remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information ,please
contact aqualified specialist workshop.
Storet he remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren. The remote control has
arange of approx-
imately 300 metres. This range is reduced by:
R sources of radio interference
R solid objectsb etween the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmittingf rom an enclosed space
If the remote control battery is low, the bat-
tery symbol on the left of the display is shown as empty. Replace the remote control battery
and observe the important safety notes when doing so (Y page 171).

169Climatecontrol Z

The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehi-
cle.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately 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 start simmedi-
ately.
Ac heck which periodically establishes aradio
connection between the vehicle and the key
determines whether avalid 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 95)
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. amobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. ametal 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 ashort
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 frontd oor (Ypage 101), 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
start/stop automatic engine switch-off func-
tion.
Key positions with KEYLESS-GO :
Start/Stop button
; Ignition lock
When you switch on the ignition ,all of the
indicator lamps in the instrument cluster light up. Further information on situations where
an indicator lamp either fails to go out after
starting the engine or lights up while driving
(Y page 330).
If Start/Stop button :has not yet been
pressed, this corresponds to the key being
removed from the ignition.
X To switch on the power supply: press
Start/Stop button :once.
The power supply is switched on. You can
now activat ethe windscreen wipers, for
