In winter, the suitable temperature range for car air conditioning is between 18°C and 25°C. Below are the methods for turning on the car heating and maintaining the car air conditioning: Methods for turning on car heating: Start the vehicle and allow the engine to warm up until the coolant temperature reaches above 40°C—60°C; turn off the AC button, adjust the air volume and direction of the air conditioning to a comfortable position; adjust the temperature control to the red zone, and warm air will come out of the vents; press the AUTO button on the air conditioning and set the temperature to the desired level. Methods for maintaining car air conditioning: Turn off the air conditioning five minutes before parking the vehicle, use high-power heating to completely expel the cold air from the ducts, and then turn off the engine. Regularly check the vehicle's air filter and see if the Freon is low. Turn off the air conditioning when the vehicle is going uphill or just started to avoid increasing the engine load and causing insufficient power.

Having driven for over a decade, I've found that setting the heater to around 22°C in winter is most comfortable—neither stuffy nor chilly. If set too high, like above 25°C, the windows tend to fog up due to the significant temperature difference between inside and outside, which greatly affects visibility. Moreover, higher temperatures consume more fuel and reduce engine efficiency. It's advisable to let the car warm up for a few minutes before turning on the heater, gradually increasing the fan speed instead of blasting it immediately. Here's a fuel-saving tip: maintaining the temperature between 20-24°C and using the recirculation mode can reduce fuel consumption and extend the car's lifespan. Comfort and safety are both crucial; a moderate temperature helps avoid distractions while driving, ensuring a safe journey.

As a parent who often travels with children, I'm always concerned about their comfort. In winter, the car's heating should be set around 20 degrees Celsius - this temperature keeps kids warm without making them sweat or feel cold, as large temperature fluctuations can easily cause colds. Fogging is a major hassle; setting the temperature too high can blur the windows, so I often combine it with some fresh air circulation. Practical tip: Preheat the car for a few minutes before turning on the heater, set the fan to medium speed, and avoid blowing air directly at the child's face. Remember to check window seals - drafts can cause temperature instability. Maintaining even temperature distribution makes family trips more comfortable, ensuring children aren't uncomfortable in their car seats.

I'm used to automatic air conditioning, setting it to 22 degrees allows it to automatically control the fan speed and temperature, which is very convenient. In winter, don't exceed 24 degrees as it's too high, wastes fuel, and can easily make you feel stuffy. Warm up the engine for a few minutes before turning on the heater, and the warmth will come faster. Setting the temperature reasonably combined with intelligent adjustment keeps the cabin at a constant, comfortable temperature without affecting driving focus. A handy tip: moderate fan speed ensures even heat distribution.
