Notes:
◆ To ensure that misted windows are de-misted as soon as possible, air recirculation mode will not operate
with "air to windscreen". (Switch -E159 is released mechanically via the rotary control).
◆ In air recirculation mode, the windows may become misty (the air humidity inside the vehicle increases and
moisture condenses on the windows - the air is not dried as it is in vehicles with air conditioners).
◆ Different types of the heater controls:
