Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.

The perfume atomizer helps to improve driving
comfort.
Via the multimedia system you can:
Rswitch the perfume atomizer on/off
Rregulate the perfume intensity (Ypage 247).
The following conditions can affect your percep-
tion of the perfume intensity:
Roperating mode of the climate control system
Rinterior temperature
Rtime of year or day
Rair humidity
Rphysiological condition of occupants, e.g. fati-
gue or hunger
The perfume atomizer can only be operated
when the climate control system is switched on
and is only active when the glove box is closed.
The perfume atomizer is provided with a pre-fil- led vial. You can also choose from a variety of
filled perfume vials and an empty vial which you
can fill yourself.
If you refill an empty perfume vial, observe the
separate information sheet attached to the vial.
!If you do not use genuine Mercedes-Benz
