Drivers are being urged to use a little-known button in their car to reduce their fuel consumption.
The air recirculation button works by using the cool air you get from your AC when you first turn it on.
It helps your car get as cool as possible after you've turned your air conditioning off, by keeping the cold air trapped inside.
The idea is that by switching on your air recirculation button, and turning off the AC after a few minutes, you'll use less fuel compared to keeping the air conditioning on constantly.
The air recirculation button has an image of a car with an arrow inside it, reports The Express.
"If you don’t know what the recirculation button does and have been blasting the air con to try to cool passengers on the back seat, you’ve been missing a trick and paying for it," said Luke Bosdet, AA spokesperson.

Of course, the best way to keep your fuel consumption down is to switch off your air conditioning altogether.
This is especially relevant at lower speeds, when you should roll your window down instead.
For higher speeds, you might want to consider using the AC instead of your windows, as your car is more likely to experience drag - and therefore work harder - when you’re travelling more quickly.
Air conditioning makes your car use more energy, which is why it has an impact on how much petrol or diesel you’re using.
You should always try and park in a shaded spot if possible to reduce how hot your car gets. This could mean you reduce the need of having to switch on your AC at all.
"It is possible on longer trips and faster roads that the air vents will generate enough air flow for the car to remain comfortable after the air con has done its initial job and can be switched off," said Mr Bosdet.
In other motoring news, drivers who take medication to combat hay fever have been warned they could face being jailed and banned from driving.
Some antihistamine tablets can make you less safe on the road, as they could cause drowsiness, nausea and blurred vision.
They might be legal to take, but they could still end up putting you on the wrong side of the law.
This is because it is illegal to drive if you’re unfit to do so because you’re on legal or illegal drugs.
Legal drugs can include prescription or over-the-counter medicines - there isn't a full list as such.
