To keep your car interior cooler in summer:

  • When the air conditioner is on, if you activate the outside air circulation mode, it can reduce the cooling performance of the car’s AC by half. When the AC is running, you should set the ventilation system to recirculation mode so the cabin can be cooled as efficiently as possible. This is an important tip to increase the cooling efficiency of the car’s air conditioner that many people are not aware of.

  • When you are smoking or there is a bad smell inside the cabin, you should only use the external air intake mode.

  • If the car interior is very hot, you can slightly open the AC vents and then lower the windows by a few centimeters for 10 to 20 seconds. This allows the hot air to be pushed out through the windows.

  • Setting the AC to a lower temperature when starting it can provide maximum cooling with minimum fuel consumption.

  • Make sure to clean the air conditioner filters carefully, as dirty filters can block airflow.

  • When using the car’s air conditioning, try not to open and close the doors frequently.
