How to Turn on the Car's Heater?

First, start the car to warm it up. Wait until the temperature gauge reaches the middle position, then turn on the heater and set the air circulation to external circulation. Wait for 2 to 3 minutes until the cold air inside the car is expelled, then switch the air circulation to internal circulation.
Turning on the car heater is quite simple. After starting the engine, wait a few minutes for it to warm up so the coolant temperature rises and the heater becomes effective. Then locate the temperature knob on the center console and turn it to the position with a red dot or high-temperature marking—this activates the heating mode. You can adjust the fan speed as needed, but remember to turn off the A/C button to save fuel, as it compresses cold air and isn't suitable for the heating system. When using the heater, adjust the vents to face you, and the recirculation mode can quickly warm up the cabin—just avoid using it too long to prevent stuffy air. Safety tip: If the heater doesn't warm up after the car has been idle for a while, check for coolant leaks or fan malfunctions. Especially in winter, ensure the heater works before driving to prevent window fogging and visibility issues.
I learned from daily driving that the key to turning on the heater is when the engine is warm. After starting the car, wait a minute or two, then locate the temperature control knob on the dashboard and turn it towards the high-temperature setting. At this point, the fan will automatically or manually blow out warm air. Turn off the A/C button to save power, as the heater comes from the engine's residual heat and doesn't require a compressor like the air conditioner. If the car is equipped with an automatic climate control system, press the AUTO button and set a comfortable temperature, such as above 20 degrees, and the system will automatically manage the airflow and heat output, which is super convenient. Related tips: Preheating the engine before driving in winter can produce warm air faster. Use the recirculation mode to quickly heat the air inside the car, then switch back to fresh air mode to maintain freshness. Occasionally check the coolant level to prevent system failures and ensure a safe and comfortable long-distance drive.
