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 25). 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
The automatic climate control regulates the
temperature and the humidity in the vehicle
interior and filters undesirable substances
out of the air.
Dual-zone automatic climate control is only
operational when the vehicle is ready to drive. Optimum operation is only achieved with the
side windows closed.
Always keep the ventilation flaps behind the
side paneling in the cargo compartment clear.
Otherwise the vehicle will not be ventilated
correctly.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 84). 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 always observe 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.
i It is possible that under certain circum-
stances the residual heat function may be
activated automatically an hour after the
SmartKey has been removed in order to dry the automatic climate control. The vehicle
is then ventilated for 30 minutes. 116

control
Climate control system The following contains instructions and rec-
ommendations to enable you to get the most
out of your dual-zone automatic climate con- trol.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps in the
à and¿ buttons light up.
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 Overview of climate control systems

the front-passenger side as well. The indi-
cator lamp in the ábutton goes out.
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/
COMAND display (see separate operating
instructions). You will see the current set-
tings of the various climate control func-
tions.
You can choose between various drive pro-
grams with the program selector button
(Y page 137). If you have selected drive pro-
gram E+, the climate control switches to Eco
mode and thermal comfort is impaired.
In Eco mode:
R the cooling output is reduced when cooling
R heat output is reduced when heating
R the time for which the rear window
defroster will run is reduced
If you have selected drive program Eor Sthe
climate control switches to Comfort mode.
The current climate control settings are main- tained in Comfort mode. Operating the climate control sys-
tems Switching climate control on/off

air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only

air dehumidification
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 fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air-dehumidification" func-
tion is operational when the vehicle is ready
to drive. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion. 118

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, only deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
