Drivers are being urged to make use of a little-known button in their cars that may help improve fuel consumption.
The button will help increase efficiency and should work in different types of cars, including petrol, diesel and battery-powered vehicles.
The ‘hidden’ button could help you save money, so it is absolutely worth checking to see if your car has it sooner rather than later.
This is especially the case amid a surge in fuel prices, which are set to continue skyrocketing, the Express reports.
The button changes the way that your air-conditioning works, in order to use less energy.
It will come as no surprise to motorists that an air-con system uses engine power in diesel and petrol cars, and battery power in electric vehicles.
For internal combustion engines, that can lead to a much bigger fuel consumption.
The system usually works by taking the outside air and then heating or cooling it.
However, drivers have now been told that this method uses much more fuel compared to the option which lets the car’s air-con system use the air from inside the car.
Thankfully, there is a button specially designed to let motorists choose which option they prefer.
If activated, the air recirculation button allows the aircon to use the air from inside the car by drawing it through vents.
And, at the same time, it stops the outside air from getting in.
The button is usually located around the aircon dial that allows the driver to set the internal temperature. It has a picture of a car with an arrow inside it.
Using the button will help reduce fuel consumption as it puts less strain on the car’s engine.
The principle is the same for electric cars as the aircon will put less strain on the battery.
Bradley Jando of Kwik Fit said: “The compressor requires energy to run your vehicle’s air conditioning system and so will use a small amount of fuel whenever the system is running.
“It could increase your fuel usage by as much as 10 percent, and the effects are particularly noticeable on short journeys.
“When you initially set off, the air con has to work hard to bring the internal temperature down to a comfortable level.”
Despite the reduction in fuel consumption the RAC adds: “Don’t use your air conditioning unless you really have to as it uses engine power and therefore increases fuel consumption.
“This goes for heat as well as cooling, so try to dress for the weather, even inside your car, if fuel efficiency is a big concern.”
The news comes as British motorists are facing the highest petrol and diesel prices on record.
Fuel prices hit record highs with motorists expected to pay 185.04p per liter of petrol and 190.92p per liter of diesel.
The latest RAC Fuel Watch indicates that both prices are still likely to rise.
The cost of filling up an average 55-liter family car went above £ 100 for the first time ever last week.
And, the crisis is not showing any signs of slowing down.
Several motorists reported that they even spotted some filling stations asking for over £ 2 for a liter of fuel.
