As temperatures soar across the UK, millions of drivers are reaching for their air conditioning controls - but most are missing a crucial feature that could save them significant money on fuel while keeping their vehicle comfortably cool.
The Secret Behind Your Car's Climate Control
Modern vehicles come equipped with a recirculation button, typically marked with a car icon containing a curved arrow. This unassuming feature, often overlooked by drivers, could be the key to more efficient cooling and reduced fuel consumption during the summer months.
When activated, this button prevents your car from constantly drawing in hot outside air, instead recirculating the already-cooled air within your vehicle's cabin. The result? Your air conditioning system works far more efficiently and uses substantially less energy.
Why This Simple Switch Makes All The Difference
Fuel Efficiency Benefits: Running your air conditioning can increase fuel consumption by up to 10%, according to motoring experts. By using the recirculation function correctly, you can cut this figure significantly as your AC compressor doesn't need to work as hard to cool incoming hot air.
Faster Cooling: The recirculation mode can cool your car's interior up to three times faster than standard air conditioning settings. This is particularly valuable when returning to a sun-baked vehicle after shopping or work.
When NOT to Use This Feature
While the recirculation button offers clear benefits during hot weather, there are situations where it's best turned off:
- When first entering a very hot car - open windows briefly to release trapped heat first
- During humid conditions when window fogging becomes a risk
- On long journeys to ensure adequate fresh air circulation
- If carrying multiple passengers to prevent stuffiness
Expert Driving Tips for Summer
Combining the recirculation button with other smart techniques can maximise your comfort and savings:
- Park in shaded areas whenever possible
- Use sunshades on your windshield and windows
- Open windows briefly before activating AC to purge hot air
- Set your temperature to a comfortable 21-22°C rather than maximum cooling
- Maintain your AC system with regular servicing
This simple dashboard feature represents one of the easiest ways to improve your driving experience during heatwaves while keeping more money in your pocket through reduced fuel consumption.
