When to activate it? And above all… when to avoid it?
As is often the case, the secret is moderation . Using air recirculation occasionally is fine. But continuously? Not recommended.
Here are the good reflexes to adopt:
To activate:
- When it’s very hot and you’ve just started the car.
- In the middle of a traffic jam, surrounded by exhaust pipes.
- If you are going through a tunnel or an area with strong odors.
To avoid:
- During long journeys without stopping: the air quickly becomes loaded with carbon dioxide , which can lead to a feeling of fatigue.
- In wet or cold weather: windows can quickly fog up.
- When there are several passengers on board: humidity rises quickly, and the air becomes stifling.
The ideal? Use it for short periods , then return to conventional ventilation to renew the air. Some modern cars manage this automatically. If not, it’s up to you to think about it!
