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.
i Read the information on qualified special-
ist workshops: (Y page 26). 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 "demist windscreen" 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.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 149).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 97). 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. It also reduces gaseous pol-
lutants and odours. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve the interval for replacing the filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. 138

automatic climate control
Automatic climate control The following contains notes and recommen-

R Activate climate control using the Ãand
¿ buttons. The indicator lamps above
the à and¿ buttons light up.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" func-
tion 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 oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
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 above the ábutton goes
out.

change the settings of the climate control
system, the climate status display appears for approximately three seconds at the bot- Overview of climate control systems

Activating/deactivating the cooling
with air dehumidification function
General notes 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,
only switch off cooling with air dehumidifica-
tion for a short period.
The cooling with air dehumidification function is only available when the engine is running.
The air inside the vehicle is cooled and dehu-midified according to the temperature selec-
ted.
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 mal-
function.
Activating/deactivating X
To activate: press the¿button.
The indicator lamp in the ¿button lights
up.
i In vehicles with auxiliary heating, one of
the indicator lamps on the auxiliary heating
button lights up when the "cooling with air
dehumidification" function is activated.
X To deactivate: press the¿button.
The indicator lamp in the ¿button goes
out. The "Cooling with air dehumidification"
function has a delayed switch-off feature. Operating the climate control system

Problems with the "Cooling with air dehumidification" function
Problem
Possible causes/consequences and
M
MSolutions The indicator lamp in
the
¿ button
flashes three times or
remains off. The cool-
ing with air dehumidifi-
cation system cannot
be switched on. Cooling with air dehumidification has been deactivated due to a
malfunction.
X Visit a qualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is
maintained automatically at a constant 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,
only switch off cooling with air dehumidifica-
tion for a short period.
Activating/switching X

lock (Y page 159).
X Set the desired temperature.
X To activate: press theÃbutton.
The indicator lamp in the Ãbutton lights
up. Automatic air distribution and airflow

The "Set climate mode" function is only avail-
able with THERMOTRONIC automatic climate control.
In automatic mode you can select the follow-
ing climate modes:
FOCUS high airflow that is set slightly cooler
MEDIUM medium airflow, standard setting
DIFFUSE low airflow that is set slightly warmer and with less of a draught

General notes The rear window heating has a high current
draw. You should therefore switch it off as
soon as the window is clear. It otherwise
switches off automatically after several
minutes.
If the battery voltage is too low, the rear win-
dow heating may switch off.

Problems with the rear window heating
Problem
Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat- ing can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows misting up.
The operation of air-recirculation mode is thesame for all control panels.

THERMOTRONIC automatic climate con-
trol: air-recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp above the g
button does not light up. Outside air is
added after about 30 minutes.
