The method to turn on the heater in a BMW 523: Simply increase the temperature setting and then select an appropriate fan speed. There is no need to press the AC button when using the heater, as the AC button is the cooling switch for the car's air conditioning system. The car's air conditioning is an important comfort feature, capable of both cooling and heating. The principles of cooling and heating in a car's air conditioning system are quite simple. When heating, the high-temperature coolant from the engine flows through the heater core, and the air blown by the blower also passes through the heater core, allowing the air vents to blow warm air. The BMW 523 has a body length of 5047mm, width of 1860mm, height of 1491mm, and a wheelbase of 3108mm.
Turning on the heater in a BMW 523 is actually quite simple, just like operating my own car. First, start the engine and let it run for a while to warm up—this ensures the heater works effectively. Then, locate the air conditioning section on the center console. Turn the temperature knob toward the red markings, or use the digital buttons to set it to around 20 degrees Celsius, whatever feels comfortable. You can slightly increase the fan speed to get warm air faster. If it's an automatic climate control system, just press the AUTO button, and the system will adjust the fan speed and temperature on its own—super convenient. In winter, the defrost function is incredibly useful, and I always remind myself to select the external air circulation mode to keep the air fresh. Remember not to turn it on immediately after a cold start, as it might blow cold air—wait until the engine warms up for better efficiency.
