Checked against the English BEV manual linked below. China-market reports identify the owner question; they do not establish an export defect, a recall or a guaranteed fix. Match the handbook and equipment in your car, and follow current on-screen instructions where software differs.

THE QUICK ANSWER

Tap Front Windshield Defrost once for rapid demisting; in the checked manual this uses fan level 7 and outside air. A second tap selects automatic demisting and a third switches it off. Keep the glass clear before continuing.

The China-market owner report

A Chinese B10 poster describes recurring mist when using recirculation. Their proposed sunroof workaround is not used here; the export manual supplies a dedicated defrost sequence.

Before you start

If visibility is inadequate, stop safely. Clear snow/leaves from the exterior air intake and avoid covering the defrost vents with objects on the dashboard.

What to check

1Select rapid demistingOpen the A/C controls and tap Front Windshield Defrost once. Check the selected indication; the manual specifies maximum fan level 7 and outside-air mode.
2Wait for a clear viewAllow the windscreen and side areas needed for driving to clear. Do not wipe the screen or operate complex menus while moving.
3Use automatic demisting if neededTap the same control again for automatic defrost/defog operation. The fan then varies automatically while outside air remains selected.
4Switch off only when appropriateThe third tap turns demisting off. If fog returns, restore the function rather than continuing with restricted visibility.

Tick steps as you go. Your progress stays in this tab.

Check the result

The windscreen should become clear enough for safe driving. Persistent poor airflow, immediate recurring fog or a failed defrost control needs inspection; the forum does not establish a universal A/C software fix.

Common questions

Should I use heating alone?+

The handbook specifically directs owners to front/rear defrost when windows fog.

Is leaving the sunroof open required?+

No. The verified procedure uses the dedicated climate-control function.
