How to Turn on the Heater in BYD Song Plus?

[OSimon]

Do not immediately turn on the heating air conditioning when warming up the car in the morning. Wait until the water temperature in the radiator rises before turning on the air conditioning. Do not set the air conditioning temperature too high. Prolonged exposure to excessively hot temperatures can make the driver drowsy and affect driving. Additionally, avoid directing the warm air directly at the driver's face. After turning on the heater, if the windows start to fog up, most people tend to turn off the heater or use cold air to clear the fog. Instead, increase the heater fan speed and let it blow for a while longer. At this point, check if the air filter is too dusty or if the airflow regulator is malfunctioning. If so, it's advisable to visit a repair shop for inspection.

I've been driving the Song Plus for a while now, and using the heater is actually quite simple. After starting the car, don't rush—wait until the water temperature gauge on the dashboard rises to the middle position before operating it, as the engine heat will be sufficient by then. Simply rotate the temperature knob on the center console toward the red H direction, and set it above 23°C to get warm air. Here's the key point—never press the A/C button with the snowflake icon, as that's for cooling. If you're too lazy to adjust the fan speed, pressing the AUTO button near the steering wheel for automatic temperature control is the most hassle-free option, and it can be used in conjunction with the seat heating function on cold days. When you first turn on the heater, it's recommended to select the recirculation mode for faster warming, but remember to switch to external circulation after a while, otherwise the windshield is prone to fogging up.

The heating system in the Song Plus operates using waste heat from the engine, unlike the air conditioning which requires a compressor. If the windshield is frosted in the morning, I usually start the vehicle remotely to warm it up for about ten minutes before driving. It's best to wait until the engine coolant temperature rises before turning on the heater, and setting the temperature directly above 26°C works most effectively. The fan icon on the air conditioning panel controls the airflow speed—setting it to level three or four in winter is sufficient, as higher speeds can dry out the air too much. Adjust the vent direction to blow downward; warming the feet makes the whole body feel comfortable. If you have children in the back, remember to increase the temperature of the rear vents separately. Also, if you use the heater frequently, make sure to replace the cabin air filter regularly to avoid a dusty smell from the vents.

Last time my friend was shivering from the cold in my car, turns out he didn't know how to operate the heating in a new energy vehicle. The operation is actually quite intuitive: After starting the vehicle, find the temperature number on the left side of the center console screen, tap the upward arrow to adjust it to around 25°C. Physical buttons are even simpler - just turn the round temperature control knob to the red zone. Special note: Hybrid versions heat up faster in winter when using HEV mode. Don't worry if there's a slight plastic smell from the vents initially, it's normal for new cars. If the windows fog up, switch to defog mode for two minutes and it'll clear right up. I've driven this car through three winters now, and the heating system has never given me any trouble.

Tips figured out during sub-zero temperatures in the north: Turn on the seat heater first thing in the morning while directly rotating the AC temperature knob to the maximum 28°C. No need to press any extra buttons – warm air will start blowing within 2-3 minutes. Remember to turn off the A/C switch icon on the central display to avoid wasting fuel by mixing cold air. Medium fan speed works best as high speed may draw odors from the engine compartment. Using external circulation during rain/snow combined with mirror defogger is particularly effective to prevent side window frost. Monthly coolant level checks are recommended to ensure proper heat exchange system operation.

I used to worry about the fuel consumption of the heater when driving a gasoline car, but after switching to the Song Plus, I found that the electric air conditioning is much more efficient. The most convenient operation is to press the AUTO button on the central console and set the temperature between 23-26°C. It's important not to turn on the heater immediately after starting; wait until the power battery warms up for better performance. For airflow, it's recommended to choose the combination mode of foot vents + windshield defroster, which keeps your feet warm and prevents window fogging. During long trips, it's fine to sleep with the heater on, as the system automatically switches between internal and external air circulation. During regular maintenance, ask the technician to clean the air conditioning ducts to improve heating efficiency. Before parking in winter, turn off the AC and switch to external circulation five minutes in advance to reduce moisture and mold in the ducts.
