Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 26). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging 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 windshield 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 can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 144).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 98). This
will speed up the cooling process and the
desired 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 odors. 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 Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet. 132

tion briefly until the windshield is clear

Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.

perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp above the ábutton goes

Optimum use of 3-zone automatic cli-
mate control
Climate control system The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to set the climate mode
(FOCUS, MEDIUM or DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since 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 and the rear com- partment as well. The indicator lamp above
the á button 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 function can only be activated or deac-
tivated with the ignition switched off.
R If you change the settings of the climate
control system, the climate status display
appears for approximately three seconds
at the bottom of the screen in the Audio or
COMAND display (see separate 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 system only operates at a reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Y page 154). Operating the climate control sys-

X Visit a qualified specialist workshop. Setting climate control to automatic
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 necessary, 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 fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
