THIS AC hack makes your car ten times colder - and it doesn’t cost a penny.
The little known dashboard button will help make your life easier this summer.
Drivers are being told with just a press of the button, their gas-guzzling AC works far more efficiently, meaning they'll money on fuel.
Before turning on the air conditioning, Brits should run the fan on the highest setting for a minute or two before activating the AC.
This helps to expel hot air from the vents and reduces the time needed to cool the cabin.

Brits should then use the recirculation button which takes the air from inside the car, rather than the outside, and recirculates it in the vehicle’s interior.
This mode means the air is cooled much faster - and reduces the workload on the AC system.
The air-con system in your car relies on power from the engine in order to function, or directly from the battery in the case of EVs.
If you're constantly drawing in air from the outside and either heating or cooling it, then the car will be using more power than if you recirculate the air already moving through the system instead.
It helps electric cars, too - the onboard heater will require less energy to function, thereby saving drivers precious miles of range.
Not only that, but it can also help to beat the scourge of the summer for many Brits, that being hayfever.
By recirculating inside the car, the air is filtered repeatedly, while the pollen-laden air from outside is kept at bay.
This can mean less pollen in the air you're breathing and, therefore, less severe hayfever.
However, if you find a musty or damp smell fills the cabin when you turn on the recirculation, you may need to do a bit of DIY maintenance.
It could be an indication that your car's air filter is in need of a change.
