Drivers are only just realising what common button found in most cars does


Motorists have been left stunned after realising what a common button in most vehicles on UK roads is actually used for.

One road user said they hadn’t understood the true meaning behind the tool for a whopping 40 years in a major revelation.

It comes after experts from Consumer Reports explained the purpose of the recirculation button usually found on the dashboard of vehicles.

The buttons logo is of a transparent car with a looping arrow inside but many were not aware it could help petrol and diesel drivers save fuel.

Speaking on TikTok, Consumer Reports said: “Now we’ve had a bunch of questions about the recirculation mode on your air conditioning system.

“Some people were concerned it’s going to seal off the car and you’re just going to be breathing in your own carbon dioxide.

“Well don’t worry no matter what mode you’re in there’s still some fresh air that’s going to be coming in.

“But what it does do is recirculate a lot of the air in the car in order to make it so the air conditioning doesn’t have to work as hard. This allows it to cool off quicker and use less energy and fuel when it’s working.”

“But you do want to use the outside air once that initial cool-off happens. Fresh air is going to be better for you and if you’ve got a car full of people you are going to be inhaling a lot of stuff they exhale.”

They added: “One more tip, make sure you know where that recirculation button is and you can get to it quickly because if you’re driving along and you see smoke coming out of a truck or you see a skunk on the road, you want to be able to hit that button quickly. It’s going to stop a lot of that bad smell from getting to you.”

Social media users were quick to show their surprise at the news with many admitting they had been left in the dark for decades.

@barbakp remarked: “O. M. G!!! All this time. THANK YOU!!!!” @nattieb2 stressed: “My allergist told me to leave it on all the time.”

@znelson85 continued: “Also useful for construction sites and those lovely tones of year when farmers are tilling, harvesting, or burning their fields.”

However, Consumer Reports urged road users to not press their recirculation button at certain times. They suggested using the tool during periods of cold weather could backfire with windows likely to fog up, preventing drivers from seeing the road ahead.

A spokesperson commented: “Now when it’s cold outside you really don’t want to run recirculation mode. That’s because if the air outside is colder than the air inside, the glass is going to be colder to touch.

“What that means is if there’s humidity in the air it’s going to condensate on those windows and fog them right up.”
