  • Switch off the function - no symbol illuminates.
For cars with heated windscreen there are two defrost levels:
  • Start the heating for the windscreen1 - symbol (1) illuminates in the screen.
  • Start the heating for the windscreen1 and air flow to the windows - symbols (1) and (2) illuminate in the screen.
  • Switch off the function - no symbol illuminates.

 Note

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

 Note

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

 Note

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

The following also takes place when the function is active 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.

 Note

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

When the defroster is switched off the climate control returns to the previous settings.
