that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.

the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.

windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the 0001or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
sensitive than in the 0001position, causing
the windshield wipers to wipe more
frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could

General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
