How to Turn on the Air Conditioning When Driving in Hot Weather?

First, press the one-touch start button, then locate the vehicle's air conditioning control unit. Press the ON button to turn on the air conditioning. Next, rotate the temperature adjustment knob clockwise. Open all the windows to allow the hot air inside the car to be blown away. When the vehicle speed reaches 60 kilometers per hour, you can roll up the windows to cool down the interior more quickly.
In this scorching heat, there are some tips for turning on the car AC. I usually start the engine, wait about ten seconds, and then turn on the AC. Never close the windows immediately—first, open them to ventilate for a few minutes to let the hot air escape before closing them and switching on the AC for cooling. Avoid pointing the AC vents directly at your face, as it can cause headaches; adjusting them upward or toward the windshield is more comfortable. Automatic AC makes things easier—just press the AUTO button and set the temperature, and the compressor will adjust its power automatically. If you notice a strange smell, it’s likely time to replace the cabin air filter—I check mine every year before summer. On long trips, remember to switch to fresh air mode periodically; otherwise, high CO₂ levels can make you drowsy. For those concerned about fuel consumption, turning the temperature up by two degrees and increasing the fan speed can achieve a similar cooling effect—I’ve personally saved half a liter per 100 km this way.
Our family always does this before going out: we remotely start the air conditioning via a mobile app to cool down the car in advance, so we don't get burned when getting in. While driving, we set the front air conditioning to 22°C, and if there are no passengers in the back, we turn off the rear vents to cool faster and save energy. Special attention is paid to the child safety seat—never let it face the vent directly. Instead, we drape a thin scarf over the vent as a deflector. In traffic jams, we turn off the external air circulation to avoid inhaling exhaust fumes. Five minutes before turning off the engine, we switch off the AC and turn up the fan to dry out the moisture in the ducts, preventing mold. Personally tested for three years—no odors at all.
