How to turn on your car’s air conditioning correctly: step-by-step

Summer heat inside the cabin can turn a trip into a real challenge. A car air conditioner (or climate control) quickly saves the day, but it’s important to switch it on correctly — so cooling is effective, economical, and safe for your health and the engine. And to add more comfort and coziness to your car’s interior, you can use tuning accessories, a wide selection of which is available in our online store.

Step-by-step guide to the perfect climate

For the A/C to work efficiently, follow this routine:

1. Ventilate. Before driving, open all windows for 1–2 minutes. This lets hot air escape naturally, reducing the load on the compressor.
2. Start the engine. Don’t turn cooling on immediately after turning the key. Let the engine run for 30–60 seconds.
3. Activate the system. Press the A/C (Air Conditioning) button and set the desired temperature. If there’s an AUTO button — press it, and the climate control will select the settings itself.
4. Recirculation mode. Turn on interior air recirculation. This way the system won’t waste energy cooling hot outside air; it will only further cool the already chilled air in the cabin.
5. Airflow direction. Aim the vents upward or to the sides, but never directly at yourself, to avoid catching a cold.

What should you avoid?

• Sudden temperature drop: Don’t set +16°C if it’s +30°C outside. The optimal difference is 5–8 degrees.
• Skipping service: Once a year, check the refrigerant level and the condition of the cabin filter. A dirty filter is the main cause of unpleasant smells and weak airflow.

Remember: 5 minutes before stopping, turn off the A/C and leave only the fan on. This helps dry out condensation and prevents bacteria from multiplying.
