Where is the warm air switch for the BYD Song?

The warm air switch for the BYD Song is located below the vehicle's central control screen. Click the fan icon to turn on the air conditioning, then use the up and down arrow buttons on the left to adjust the desired warm air temperature. Once the engine coolant temperature stabilizes, warm air will be blown out. Use the up and down arrow buttons on the right to adjust the airflow intensity. Impact of air conditioning fan speed on fuel consumption: Turning on the air conditioning consumes more fuel primarily because the air conditioning compressor requires significant power to operate. However, changes in fan speed have minimal impact on power requirements. Therefore, within a certain speed range or wind resistance level, using air conditioning increases fuel consumption while turning it off saves fuel. The effect of air conditioning fan speed on fuel consumption is negligible, including when using only warm air in winter. Impact of air conditioning temperature on fuel consumption: When it's too hot or too cold and air conditioning is necessary, avoid setting it to the coldest or hottest extremes. Moderate temperatures are sufficient, as excessively low or high settings waste fuel.
When I first got my Song, I couldn't find the heater switch either. Later I discovered it's actually on the central AC control panel. See that temperature knob with red and blue markings? Turn it all the way to the red side, turn off the A/C button directly, then increase the fan speed - warm air will come blowing out. However, it blows cold air when the engine coolant temperature is low; you'll need to wait until the temperature gauge reaches the middle position for warm air. In winter, I usually use the steering wheel heater first, then turn on the cabin heater after 3-5 minutes to avoid freezing hands. The remote start feature for climate control is also quite practical - you can preheat the cabin in advance using the mobile app.
After driving the Song Pro for three years, I've found the heater switch is cleverly hidden in the air conditioning control panel. That circular temperature knob? Just twist it toward the red zone to warm things up. There's an even quicker method: press the voice button on the steering wheel and say 'turn on the heater' - the system will automatically raise the temperature and turn off the AC. One important note: the heater won't perform well until coolant temperature reaches 90°C, so I recommend waiting after morning starts. My routine is to first activate seat warmers for quick comfort, then wait 2-3 minutes before turning on the heater - this also helps prevent window fogging. The automatic climate control's temperature maintenance feature works great; setting it at 25°C keeps the cabin perfectly comfortable.
