Subaru Ascent windshield defrosting airflow modes selection

Select the " Subaru Ascent front defrost icon " or " Subaru Ascent full defrost icon " mode to quickly defrost or remove moisture from the windshield and front side windows in the Subaru Ascent.

NOTE

When either defrost mode is selected in the Subaru Ascent, the air conditioning system may activate automatically to improve defogging performance, even if the A/C indicator is not illuminated.
In addition, the system will automatically switch to outside air mode to enhance moisture removal and maintain clear visibility.

This behavior is normal and ensures faster and more effective windshield clearing.
