Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could
fog up.
To prevent the windows from fogging up:
R only switch off climate control briefly
R only switch on air-recirculation mode briefly
R for vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
R for vehicles with dual-zone automatic cli-
mate control, switch on the windshield
defrosting function briefly, if required Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
The integrated filter can filter out most parti-
cles of dust and completely filters out pollen.
In vehicles with dual-zone automatic climate
control, gaseous pollutants and odors will also
be reduced. A clogged filter reduces the air-
flow into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet. As the interval between
changes depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance
Booklet. 114

Below, you can find a number of notes and
recommendations to help you use the air-con-
ditioning system optimally. R Switch on the cooling with air dehumidifica-
tion function. The indicator lamp in the
¿ switch comes on when the function is
switched on.
R Set the temperature to

72 ‡ (22 †). Only
change the temperature in small incre-
ments. R
Only use the settings for defrosting the
windshield 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 other-
wise fog up as no fresh air is drawn into the
vehicle in air-recirculation mode. The indica-
tor lamp in the h switch comes on when
the function is switched on. Overview of climate control systems

R
If you wish to use the driver's side settings
on the co-driver's side and, for vehicles with
rear-compartment air conditioning, for the
rear compartment as well, use the "Synchro-
nization" function. The indicator lamp in the
0 button comes on when the function is
switched on.
R After long journeys, you can use the residual
heat of the engine to heat the stationary
vehicle. The residual heat utilization can
only be switched on or off while the ignition
is switched off. The indicator lamp in the
Ì button comes on when the function is
switched on.
Approximately 60 minutes after parking the
vehicle, 3-zone automatic climate control can
switch on automatically, depending on the out-
side temperature. The vehicle is then ventila-
ted for about 30 minutes at low fan setting
and 3-zone automatic climate control is dried
out. Optimum use of the rear compart-
ment air conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning
system control panel. When you switch on the
rear-compartment air conditioning, your set-
tings for temperature, airflow and air distribu-
tion are automatically adopted on the control
panel for the rear-compartment air condition-
ing.
The indicator lamp in the / button comes
on when the rear-compartment air-condition-
ing is switched on
(Y page 115).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condi-
tioning, use the control panel of the dual-zone
automatic climate control system. When you
switch on the rear-compartment air condition-
ing, you can set the temperature and airflow
separately on the control panel. The airflow
setting is automatically adopted for the rear-
compartment air conditioning. When dual-zone
automatic climate control is in à automatic
mode, the air distribution of the rear-compart-
ment air conditioning is also automatically
adjusted.
When you set the temperature and airflow of
the rear-compartment air conditioning, the indicator lamp of the / button
(Y page

116) flashes. When the rear-compart-
ment air conditioning is switched on, the indi-
cator lamp on the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on à auto-
matic mode. Only change the temperature in
small increments. Operating the climate control sys-
tem

Important safety notes When the climate control is switched off, air
intake and air circulation also stop. Only use
this setting for a brief period. Otherwise, the
windows could fog up.

midification function on/off
Important safety notes The cooling with air dehumidification function
of the air conditioning or automatic climate
control is only available when the engine is
running. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may appear on the underside of
the vehicle when in cooling mode. This is nor-
mal and not a sign that there is a malfunction.
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle
will not be cooled (in warm weather) or dehu-
midified. Therefore, only switch off the "Cool-
ing with air dehumidification" function briefly.
Otherwise, the windows will fog up more
quickly.
Switching on and off For dual-zone automatic climate control, the
function for automatic climate control settings
can only be activated or deactivated on the
first menu level. If you do not set a new value
for the rear-compartment climate control in
the second menu level within approx. ten sec-
onds, the control panel display goes back to
the first menu level.
X Press the ¿ button.
The indicator lamp in the ¿ switch

Regulating climate control automati-
cally
General notes When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification func-
tion is also activated. If desired, the cooling
with air dehumidification function can be deac-
tivated (
Y page 118).
Dual-zone automatic climate control Automatic mode for automatic climate control
settings can only be activated or deactivated
on the first menu level. If you do not set a new
value for the rear-compartment climate control
in the second menu level within approx. ten
seconds, the control panel display goes back
to the first menu level.
