Drivers are being urged to use a little-known button in their cars to help with fuel consumption.
The button will help increase efficiency and should be in petrol, diesel and battery powered vehicles.
According to the Daily Record, the button could help you cut down fuels costs, so it’s worth checking to see if you have it.

Especially since fuel prices continue to surge.
The button changes the car's air conditioning, so it uses less energy.
Air conditioning systems use engine power to work in diesel and petrol cars and battery power in electric vehicles.
This can naturally lead to greater fuel consumption.
The system takes air from outside, cools it and blows it into the car. However, drivers have been told that they can save far more fuel by switching the system to cooling air from inside the vehicle.
The air recirculation button allows air conditioning to use air from inside the car by drawing it through vents.
At the same time, it stops air from outside from getting in.
The button is normally found around the aircon dial.
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 litre of petrol and 190.92p per litre of diesel.
The latest RAC Fuel Watch indicates that both prices are likely to rise further.
The cost of filling up an average 55-litre 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 litre of fuel.
