! Do not operate the windscree
nwipers
when the windscree nisdry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscree ncan
scratch the glass if wiping takes place when the windscree nisdry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
alwayso perate them using washer fluid. !
If the windscree
nwipers leave smears on
the windscree nafter the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscree nwith washer fluida fter an auto-
matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscree nwipers may be activated
inadvertently .This could damage the wind-
screen wiper blades or scratch the wind-
screen.
For this reason, you shoulda lwaysswitch
off the windscree nwipers in dry weather. 1

X Visit aqualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is
maintained automatically at
aconstant 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,
deactivate the "Cooling with air-dehumidifi-
cation" function only briefly.
