! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto- matic car wash. Combination switch

Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual

with air dehumidification function
General notes If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi- cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only deactivate the "Cooling with air-dehu-
midification" function briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of the vehicle when cooling mode is active. Thisis normal and not a sign that there is a mal-
function. 130

mode
General notes Only THERMOTRONIC automatic climate con-
trol features the "Control climate control
automatically" function.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only deactivate the "Cooling with air-dehu-
midification" function briefly.

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i Move the adjusters for the air vents ver-
tically or horizontally, to set the direction of the airflow.
i Optimal climate control function is ach-
ieved by opening the air vents fully and set-
ting the adjusters to the middle position. Setting the centre air vents
