What does the SYNC button on a Mercedes-Benz mean?

[BrynleeFitz]

The SYNC button on a Mercedes-Benz is a control button located on the air conditioning panel. Its function is to switch between the temperature controls for the driver and passenger sides. When the button is lit, it allows for synchronized adjustment of the air conditioning temperature on both sides. When the button light is off, the temperatures can be controlled separately for each side. Below are some precautions for using the air conditioning in a Mercedes-Benz: 1. Regular Cleaning: The air conditioning system should be cleaned periodically. During use, the air conditioning tends to accumulate dust, which can form dirt and eventually lead to mold growth over time. 2. Avoid Setting the Temperature Too Low: If the interior temperature remains too low for an extended period, the body may struggle to adapt quickly, leading to various discomforts. Normally, the cabin temperature should be set to around 26~27 degrees Celsius. 3. Do Not Rest in the Car with the Air Conditioning On While Parked: When the car engine is running, incomplete combustion of gasoline in the cylinders can produce high concentrations of carbon monoxide, which can lead to poisoning or even death.
