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.

Optimum use of the air-conditioning

Below, you can find a number of notes and rec-
ommendations to help you use the air-condi-
tioning system optimally.
RSwitch on the cooling with air dehumidifica-
tion function. The indicator lamp in the
¿ switch comes on when the function is
switched on.
RSet the temperature to 72 ‡ (22 †).Only
ch ange the temperature in small increments.
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).
