How to Use Air Conditioning When Driving on Highways in Winter?
2 Answers
Methods for using air conditioning when driving on highways in winter: 1. No need to press AC when using the heater in winter: (1) After a cold start, do not turn on the heater immediately. Wait until the vehicle has traveled some distance and the temperature gauge shows half of the normal operating temperature before turning on the heater. (2) When first turning on the heater, choose a low fan speed. Once the engine reaches normal operating temperature, adjust the fan speed according to personal preference. 2. Set a reasonable air direction: In winter, adjust the air direction to blow towards the feet. This will prevent noticeable breathing discomfort and provide good heating effects. 3. Set a reasonable temperature: (1) Due to the significant temperature difference between the inside and outside of the car and the extremely dry air, keeping the heater at a lower setting can help avoid dryness and colds. (2) If the heater is set too high, it may cause drowsiness, reduced concentration, and slower reaction times for the driver.
In winter when using the air conditioning on the highway, I initially wait for the coolant temperature to rise before turning on the heater, otherwise it won't warm up efficiently and wastes fuel. Setting the temperature around 23°C with medium fan speed is sufficient. Using external air circulation helps maintain airflow inside the car, preventing fogging and drowsiness. If the windshield fogs up, immediately press the defrost button to direct airflow onto it. For long trips over two hours, it's best to prepare a bottle of water by the door to stay hydrated in the dry environment. If there are elderly or children in the back seats, avoid directing strong airflow at them. Personally, I prefer switching to external air circulation every half hour to stay alert.
