2. Better Fuel Efficiency
Air conditioning puts extra load on the engine. When the system doesn’t have to work as hard to cool incoming hot air from outside, it becomes more efficient. This can slightly reduce fuel consumption over time, especially during long drives in extreme temperatures.
3. Blocking Pollution and Bad Smells
Recirculation is especially useful in traffic jams, tunnels, or polluted areas. When activated, it prevents exhaust fumes, dust, and unpleasant odors from entering the cabin. This helps maintain cleaner air inside the vehicle, which is important for comfort and health.
However, it’s not meant to be used all the time. Without fresh air coming in, carbon dioxide levels inside the car can slowly increase, which may lead to drowsiness during long drives.
