Did you know that a simple button on your car's dashboard can have a huge impact on your fuel consumption? Find out how this little-known feature can help you save money at the pump and improve your driving comfort.
The mysterious air recirculation button
Almost all modern cars are equipped with it, but few drivers know its true potential. This button, usually represented by a car symbol with a semi-circular arrow inside, is actually the air recirculation button. Its main role is to circulate the air inside the cabin, but its benefits go well beyond that.
How does air recirculation work?
Your car's air conditioning system can draw air either from outside or inside the vehicle. When you activate air recirculation:
This function was designed to improve occupant comfort by preventing the entry of dust, pollen and unpleasant odors from outside.
The surprising impact on fuel consumption
What many don't know is that judicious use of the air recirculation button can reduce fuel consumption by up to 30%. How is it possible ?
The reason is simple: when the air conditioning system recycles indoor air, it requires less energy to maintain the desired temperature. Already cooled (or heated) air is easier to process than outside air, which can be much warmer or colder.
This reduction in the workload of the air conditioning system directly translates into reduced fuel consumption. The effect is particularly noticeable in summer, when the temperature difference between indoors and outdoors is greatest.
When and how to use air recirculation?
To get the most out of this feature and maximize your fuel savings, here are some usage tips:
Be careful though: experts recommend not using air recirculation continuously for more than 10 minutes. Prolonged use may result in an accumulation of CO2 in the cabin, which could cause the driver to become drowsy.
Other tips for reducing fuel consumption
Although the recirculation button is a powerful tool for saving fuel, there are other efficient driving techniques to adopt:
Drive smoothly: avoid sudden acceleration and sudden braking. Smooth and anticipatory driving can significantly reduce your consumption.
Use engine braking: anticipate slowdowns by releasing the accelerator rather than braking systematically.
Monitor your tire pressure: underinflated tires increase rolling resistance and therefore fuel consumption.
Lighten your vehicle: remove unnecessary loads from your trunk. Each additional kilo impacts consumption.
Plan your trips: Use apps like Google Maps that now offer fuel-optimized routes.
The importance of rational use of air conditioning
Contrary to popular belief, using air conditioning intelligently can be more economical than driving with all windows open, especially at high speeds. Here are some tips for optimal use:
Avoid extreme temperatures: setting the air conditioning to 22°C rather than 18°C can make a real difference in terms of consumption.
Ventilate before starting: in summer, open doors and windows a few moments before turning on the air conditioning. This will allow overheated air to be removed and relieve the work of the system.
Use “Auto” mode: on modern systems, this mode intelligently manages the power of the air conditioning to reach and maintain the desired temperature efficiently.
The small air recirculation button, often overlooked, turns out to be a valuable ally in reducing fuel consumption. By using it judiciously, in combination with other efficient driving techniques, you will be able to achieve significant savings at the pump while maintaining your driving comfort. Don't hesitate to activate it during your next trips, your wallet and the environment will thank you!
This little magic button on your dashboard can save you up to 30% on fuel!
