How to Adjust the Car's Air Conditioning for Hot Air?

First, press the brake pedal to start the engine. Then, turn the key to the ST position to start the engine until the idle speed stabilizes. Next, rotate the fan speed knob. Turn the temperature mode knob to the left to activate the cooling mode. Turn the temperature mode knob to the right to activate the heating mode. Press the A/C switch to turn on the compressor. Press the recirculation button to activate the internal circulation mode. To adjust the fan speed, click the fan blade icon on the air conditioning panel for up and down adjustments.
Every winter when I drive, I start the car and wait for the coolant temperature to rise before turning on the heater, so the hot air comes out faster. As soon as I get in the car, I turn the temperature knob to the red zone, making sure to turn off the AC button since it only controls cooling. Don't set the fan too high at first; wait a few minutes for the heating ducts to warm up before increasing the airflow. It's best to adjust the air vents to blow towards the feet, as warm air naturally rises and evenly warms the entire cabin. On long drives, be careful not to set the temperature too high to avoid drowsiness. Open the windows every couple of hours to let in fresh air, otherwise, the windshield will fog up and affect visibility.
As a veteran car owner, let me share some tips for adjusting the heating. First, wait until the coolant temperature gauge reaches the midpoint before turning on the heater, otherwise you'll just get cold air. For manual air conditioning, turn both left and right temperature knobs to the far right of the red zone, then adjust the central fan speed button. Automatic AC is even simpler - just press the AUTO button and set the temperature above 23°C. After 30 minutes, switch from recirculation to fresh air mode to prevent stuffiness and dizziness. If the windshield fogs up, don't rush to adjust vents - turn off the AC and increase fan speed to clear the fog quickly.
After driving for over a decade, here's how to get warm air quickly and save fuel. Don't rush to turn on the heater when you start the car—wait until the coolant temperature rises halfway before activating the fan. Set the temperature knob to the middle of the red zone, and make sure to turn off the AC button! Otherwise, the engine will have to power the compressor, increasing the load. If the windshield tends to fog up, simply select the defrost and footwell mode—warm air rising from below clears fog effectively. On long drives, if the air feels too dry, just open the windows for a few seconds to refresh the air instead of constantly adjusting the AC.
