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 125).

ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in

as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h button comes on when the function is

112Overview of climate control systems
Climate control

RIf you wish to use the driver's side settings on
the front-passenger side and, for vehicles
with rear-compartment air conditioning, for
the rear compartment as well, use the "Syn-
chronization" function. The indicator lamp in
the0 button comes on when the function
is switched on.
RAfter long journeys, you can use the residual
heat of the engine to heat the stationary vehi-
cle. 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, dual-zone automatic climate control
can switch on automatically, depending on the
outside temperature. The vehicle is then venti-
lated for about 30 minutes at low fan setting and
dual-zone automatic climate control is dried out.
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 125).
Optimum use of rear-compartment air
conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning sys-
tem control panel. When you switch on the rear-
compartment air conditioning, your settings for
temperature, airflow and air distribution are
automatically adopted on the control panel for
the rear-compartment air conditioning.
The indicator lamp in the /button comes on
when the rear-compartment air-conditioning is
switched on (
Ypage 111).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condition-
ing, use the control panel of the dual-zone auto-
matic climate control system. When you switch
on the rear-compartment air conditioning, you
can set the temperature and airflow separately
on the control panel. The airflow setting is auto-
matically adopted for the rear-compartment air
conditioning. When dual-zone automatic cli-
mate control is in Ãautomatic mode, the air
distribution of the rear-compartment air condi-
tioning is also automatically adjusted. When you set the temperature and airflow of the
rear-compartment air conditioning, the indica-
tor lamp of the
/button (
Ypage 112)
flashes. When the rear-compartment air condi-
tioning is switched on, the indicator lamp on
the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on Ãauto-
matic mode. Only change the temperature in
small increments.
Operating the climate control system
Switching the climate control on/off
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 win-
dows could fog up.

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.
