Drivers warned against pressing this button in your car which can cause more harm than good in winter

Drivers have been warned that one common dashboard button in your car could make winter driving a whole lot more dangerous.

Many people unknowingly activate a feature that makes their windscreen fog faster, slows down defrosting, and reduces visibility, a total nightmare in the winter.

The issue becomes even worse on freezing mornings when the car is already struggling to warm up.

Experts say it is one of the most overlooked causes of misted-up windows, so here’s how to avoid misty eyes due to a misty windscreen.

The winter mistake that causes more harm than good

When temperatures drop, moisture from your breath, wet jackets, damp shoes, and melting snow builds up inside your car.

That humidity settles on cold glass, turning into fog that spreads across the windscreen in seconds, and it means that drivers often crank up the heater or wipe the inside of the glass to deal with it.

But the fog returns almost immediately.

This is because one setting inside the cabin is trapping all that moisture instead of letting it escape.

The effect makes de-misting slower, increases the chance of sudden fogging while driving, and reduces visibility during early morning commutes.

Many drivers think their heater is weak or their car is simply struggling with the cold, but the real issue is much simpler.

Towards the end of the heating cycle, the problem becomes even more noticeable because the cabin feels warm, but the windows stay misty.

As humidity rises, visibility decreases, creating a hidden safety risk that many people overlook.

The air recirculation button in your car is the culprit

Experts say the air recirculation button is the cause of this winter problem.

By reusing the air already inside the cabin, it traps moisture and stops fresh air from clearing the glass.

Switching to fresh air mode brings in cold, dry air that clears condensation quickly and keeps the windscreen from fogging again.

Fresh air also reduces stuffiness on long drives, helping drivers stay more alert on dark winter roads.

With visibility already limited this holiday season, keeping the recirculation button off is one of the easiest ways to stay safe.

You might be slightly colder, but you’ll definitely be safer.
