Wiper performance in different situations:
During automatic
wipe/wash:
While the washer system is working, the
Climatronic switches to recirculation for
about 30 seconds to help prevent the washer
fluid odor from entering the vehicle interior.
During intermittent wiping: Speed-dependent interval control: The high-
er the vehicle speed, the faster the wipers
move.
When a vehicle door is
opened: The windshield wipers stop.
Heated washer nozzles
Some vehicles are equipped with heated washer nozzles. The heating thaws frozen washer nozzles, but not the fluid supply hoses. When the ignition is switched on, the heat applied to the washer noz-zles is automatically regulated depending on the outside air temperature.
If there is something on the windshield, the wiper will try to wipe it away. If it continues to block the wiper, the wiper will stop moving. Remove the obstacle and switch the wiper on again.
