Heated windscreen and IR window may have an impact on the performance of transponders and other communication equipment.


A triangular area at the end of each side of the windscreen is not electrically heated, where de-icing may take longer.


Electrically heated windscreen is not available when the engine is auto-stopped.

The following also takes place in order to provide maximum dehumidification in the passenger compartment:

  • the air conditioning is automatically engaged
  • recirculation and the air quality system are automatically disengaged.


The noise level increases as the fan is operating at max.
