A ‘magic’ button defrosts a car’s windshield in seconds – and some drivers had no idea

Why is this trick still unknown?

Many drivers have not explored all the features of their vehicle or continue to rely on classic solutions such as the ice scraper or warm water. However, this button has undeniable advantages:
Safety: avoid thermal shocks that could crack the glass.
Speed: the system acts in just a few seconds.
Effectiveness: prevents fogging during the journey.
Some tips for optimal defrosting

Keep your windows clean: dirty windows keep fogging up.
Always stay nearby: leaving the engine running unattended can be risky, or even prohibited in some cases.
