Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: ( Y page 24).
Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windscreen function
briefly, if required
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters out undesir-
able substances from the air.
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control is
only operational when the engine is running.
Optimum operation is only achieved with the
side windows and panorama sliding sunroof
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off ( Y page 135).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 88). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With THERMOTRONIC auto-
matic climate control, gaseous pollutants
and odours will also be reduced. A clogged
filter reduces the amount of air supplied to
the vehicle interior. For this reason, you
should always observe the interval for
replacing the filter, which is specified in the
Service Booklet. As it depends on environ-
mental conditions, e.g. heavy air pollution,
the interval may be shorter than stated in
the Service Booklet.
i It is possible that the residual heat func-
tion 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.124Overview of climate control systemsClimate control

Automatic climate control
The following contains notes and recommen-
dations on optimum use of THERMATIC auto-
matic climate control.
R Switch on the air-conditioning system by
turning control knob A clockwise to the
desired position (except position 0).
R Set the temperature to 22 †.
R Recommendation to avoid misting of
the windows in the event of low outside
temperatures or rain: switch on the air
distribution ¯ and if possible switch off
P and O (Y page 131).
Deactivate air-recirculation mode
e (Y page 134).
Set airflow control A to a setting between
3 and 6(Y page 131).
R Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control A to a setting between 3
and 6(Y page 131).
R Recommendation for a constant vehi-
cle interior temperature: set airflow con-
trol A to a setting between 1 and
3 (Y page 131).
R Recommendation for air distribution in
winter: select the O and ¯ settings
( Y page 131).
Recommendation for air distribution in
summer: select the P or P and
¯ settings ( Y page 131).
R Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again.Overview of climate control systems125Climate controlProCarManuals.com

ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
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. See also
the separate COMAND Online operating
instructions. You will see the current set-
tings of the various climate control func-
tions.
ECO start/stop function
During automatic engine switch-off, the cli-
mate control only operates at a reduced capa-
city. If you require the full climate control out-
put, you can switch off the ECO start/stop
function by pressing the ECO button
( Y page 149).

R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the á button goes out.

to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off.

Activating/deactivating the cooling
with air dehumidification function
Points to observe before use
If you deactivate the "Cooling with air dehu-
midification function", the air inside the vehi-
cle will not be cooled in warmer weather. The
air inside the vehicle will not be dehumidified
either. The windows can mist up more
quickly. Therefore, only switch off the "Cool-
ing with air dehumidification function" briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
