Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
i Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling process, and the desired vehicle interior tem-
perature will be reached more quickly.
i It is possible that the residual heat function
may be activated automatically an hour after
the key has been removed in order to dry the air-conditioning system. The vehicle is then
ventilated for 30 minutes to dry the air-con-
ditioning system. 122

automatic climate control
Automatic climate control The following contains instructions and recom-
mendations to enable you to get the most out of
your THERMOTRONIC automatic climate con-
trol.
R Activate climate control using the Ãand
¿ buttons on the climate control panel.
The indicator lamps in the Ãand
¿ buttons light up.
R In automatic mode, the ñbutton on the
climate control panel may be used to addi-
tionally adjust the airflow (FOCUS/MEDIUM/ DIFFUSE). The MEDIUM level is recommen-
ded.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" function
briefly until the windscreen is clear again.
R Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist
up as no fresh air is drawn into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the ábutton goes out.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when the
ignition is switched off. The residual heat Overview of climate control systems

function can only be activated or deactivated
with the ignition switched off.
R Vehicles with COMAND Online: if you
change the settings of the climate control
system, the climate status display appears for
three seconds at the bottom of the screen in
the COMAND display. You will see the current settings of the various climate control func-
tions.

control only operates at a reduced capacity. If
you require full climate control capacity, the
ECO start/stop function can be deactivated by
pressing the ECO button (Y page 136).Operating the climate control system

air dehumidification
General notes If you deactivate the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can mist up
more quickly. Therefore, deactivate the "Cooling
with air dehumidification" function only briefly.
The "Cooling with air dehumidification" function
is only available when the engine is running. The air inside the vehicle is cooled and dehumidified
according to the temperature selected.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This is
normal and not a sign that there is a malfunc-
tion.

Important safety notes G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the navigation system.
General notes Correct functioning of the navigation system
depends, amongst other things, on GPS recep-
tion. In certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
multi-storey car parks.

MAP PILOT
(see the manufacturer's operating instructions).
The Garmin ®
MAP PILOT operating instructions
are stored on the SD memory card as a PDF file. The SD card box contains a quick guide.
