The Correct Method to Activate Car Heater
2 Answers
The correct steps to activate car heater are as follows: 1. After starting the vehicle, warm up the engine first, open windows briefly before turning on the heater. 2. Set the air circulation mode to internal recirculation, which allows rapid cabin warming and prevents external polluted air from entering during smoggy days. 3. Switch the AC to warm air mode (note: do not press the AC button as it activates cooling function - engaging it during heating will only increase fuel consumption), adjust appropriate fan speed and airflow direction. 4. Once cabin temperature rises, change the circulation mode to external intake to maintain relatively fresh air inside.
Turning on the heater while driving is actually quite easy. Having driven many car models, I usually start the engine first and let it idle for two to three minutes to warm up, as the coolant needs to reach a certain temperature before blowing hot air. Then, I turn the temperature control knob to the red zone and set the fan speed to medium to quickly dispel the cold air. If the car has automatic climate control, I prefer pressing the AUTO button and setting a comfortable temperature, like 22°C, letting the system manage it automatically. In cold weather, I immediately switch to recirculation mode to heat the cabin air faster, but I avoid setting the temperature too high too soon to prevent window fogging. For safety, I use the defogger or slightly open a window to balance the temperature difference first. Regular maintenance is also crucial—for example, changing the cabin air filter every six months prevents dust buildup and odors. Overall, take it step by step; a properly warmed car ensures both comfort and fuel efficiency.
