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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
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:
Ronly switch off climate control briefly
Ronly switch on air-recirculation mode briefly
Rfor vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
Rfor vehicles with dual-zone automatic climate
control, switch on the windshield defrosting
function briefly, if requiredClimate 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-recircula-
tion 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 particles
of dust and completely filters out pollen. In vehi-
cles with dual-zone automatic climate control,
gaseous pollutants and odors will also be
reduced. A clogged filter reduces the airflow into
the vehicle interior. For this reason, you should
always observe the interval for replacing the fil- ter, which is specified in the Maintenance Book-
let. As the interval between changes depends on
environmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than stated in
the Maintenance Booklet.

ROnly use the settings for defrosting the wind-
shield briefly, until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h
switch comes on when the function is
switched on.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 123).

XPress the Kbutton and set blower setting
1 or above for the rear-compartment air con-
ditioning.
The blower settings are shown in the display
as a bar graph. The rear-compartment air con- ditioning is switched on.
XIf necessary set the temperature for the rear-compartment air conditioning using temper-
ature control :orE (
Ypage 110).
The display shows the selected rear-compart-
ment temperature.
If you do not make any more settings for
approximately ten seconds, the control panel display shows menu level 1 again for the auto-
matic climate control settings. The ind icato
r
lamp in the /button remains lit.
iThe air distribution setting applies both to
automatic climate control and to the rear-
compartment air conditioning and cannot be
set separately for the two.
XTo switch off: press the/button on the
control panel.

If you do not make any more settings for
approximately ten seconds, the control panel
display shows menu level 1 again for the auto-
matic climate control settings. The indicator
lamp in the /button goes out.
Switching the cooling with air dehu-
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 temperature selected.
Condensation may appear on the underside of
the vehicle when in cooling mode. This is normal
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 dehumidi-
fied. Therefore, only switch off the "Cooling with air dehumidification" function briefly. Other-
wise, 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 seconds, the con-
trol panel display goes back to the first menu
level.
XPress the ¿button.
The indicator lamp in the ¿switch comes
on when the function is switched on.
iThe cooling with air dehumidification func-
tion has a delayed switch-off feature.
112Operating the climate control system
Climate control

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 function
is also activated. If desired, the cooling with air
dehumidification function can be deactivated
(
Ypage 112).
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.
XSwitch on climate control (Ypage 111).
XSet temperature for the driver's and front-
passenger side and, for vehicles with rear-
compartment air conditioning, for the rear
compartment, too (
Ypage 113).
XTo switch automatic mode on or off: press
the à button.
If the indicator lamp in the Ãbutton lights
up, automatic mode is activated. The airflow
and air distribution are controlled automati-
cally and the windshield defrosting function is
deactivated.
If you deactivate automatic mode, the auto-
matic climate control system saves the current
settings.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above the Ãbutton goes out. The function
which has not been changed manually, however,
continues to be controlled automatically.
Setting the temperature
Air-conditioning system
XSwitch on climate control (Ypage 111).
XTo increase or reduce: turn temperature
control :clockwise or counter-clockwise.
When doing so, only change the temperature
in small increments, and start in the center
position or at 72 ‡ (22 †) (
Ypage 109).
Dual-zone automatic climate control
You can set the temperature separately for the
driver's and front-passenger side. In vehicles
with rear-compartment air conditioning, the
temperature for the rear can be set additionally.
Each set temperature is automatically main-
tained at a constant level.
XSwitch on climate control (Ypage 111).
XTo increase or reduce: turn temperature
control :orE clockwise or counter-clock-
wise (
Ypage 110). When doing so, only
change the temperature in small increments
starting at 72 ‡ (22 †).
The control panel display shows the set tem-
perature for the left and right side at the
respective edge of the display.

tioning, also the setting for air distribution are
also applied to the rear-compartment climate
control.

XIn warm and damp weather, do not allow cold
air to flow onto the windows. Close the side
air vents if required (

Switching the rear window defroster
on/off
General notes
The rear window defroster consumes a lot of
power. You should therefore switch off the rear
window defroster as soon as the rear window is
clear.
XTurn the key to position 2in the ignition lock.
XPress the ¤button on the control panel.
If the indicator lamp in the ¤button lights
up, the rear window defroster is switched on.
The rear window defroster switches off auto-
matically after a few minutes.
Problems with the rear window
defroster
The rear window defroster has switched off pre-
maturely or cannot be activated.
The vehicle starter battery is not sufficiently
charged.
XSwitch off any consumers that are not
required, e.g. reading lamps, interior lighting
or seat heating.
When the battery is sufficiently charged, the
rear window defroster can be activated again.
Switching air-recirculation mode
on/off
Important safety notes
You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle is then circulated.
When you switch on air-recirculation mode, the side windows and windows could fog up more
