How to Turn on the Heater in a Civic?
4 Answers
Civic's method of turning on the heater: The Civic is equipped with an automatic temperature control air conditioning system. To turn on the heater, simply rotate the air conditioning temperature control knob to the red area. When the heater is on, the AC button should be turned off. Pressing the AC button activates the air conditioning compressor, which is the cooling switch for the air conditioner, and is not needed when the heater is on. The Civic is a model under Dongfeng Honda, with body dimensions of 4649mm in length, 1800mm in width, and 1416mm in height, and a wheelbase of 2700mm. In terms of appearance, the Civic features a stylish and sleek design with smooth body lines, and its hatchback appearance has undergone significant changes compared to the older models.
When I first bought my Civic, I was also unclear about how to turn on the heater. Later, I figured it out through trial and error. First, start the car and let the engine run for a while until the water temperature rises, as only then will you get warm air. Then, locate the temperature adjustment knob on the dashboard and turn it towards the red color, which activates the heating mode. Next, press the fan button or turn the knob to increase the airflow—I prefer starting low and gradually increasing it. If you want to warm up the car quickly, direct the airflow towards the feet or the windshield to prevent fogging. This method is very convenient in winter, and turning on the recirculation mode helps retain heat better. If the air conditioning doesn’t respond, it might be because the engine hasn’t reached the required temperature yet—just wait a bit. Remember not to adjust it randomly to avoid wasting fuel. Overall, the operation is simple, and you’ll get the hang of it after a few tries.
After starting the Civic, I quickly get warm air: when the water temperature reaches halfway, turn the temperature knob to the highest setting, press the fan button to select the wind speed. It's recommended to direct the airflow to the feet for faster heating. Check the recirculation button; using the internal circulation helps retain heat better. Sometimes, even with the fan on high, the temperature isn't warm enough—just wait a few more minutes for the engine to run longer, as the warm air relies on engine heat. This setup is both safe and comfortable, especially in freezing weather to prevent icing. Additionally, don't forget to adjust the air conditioning panel buttons; the right direction enhances defogging. This method is hassle-free for daily use.
I'm used to driving a Civic. When turning on the heater, I start the engine and wait a few minutes for the coolant temperature to rise, then turn the temperature knob to the red zone and turn on the fan. Set the airflow direction towards the feet or windshield to prevent fogging. As long as the AC mode is functioning properly, there won't be any issues.
