What does the sync button mean in Mercedes-Benz?

[GiselleRose]

Mercedes-Benz sync button is a control key on the air conditioning panel. Its function is to switch the temperature control between the driver and passenger sides. When this button is lit, it enables synchronized adjustment of the air conditioning temperature on both sides. When the button light is off, it allows separate temperature control for each side. Precautions for using Mercedes-Benz car air conditioning: 1. Clean the air conditioning system periodically. During use, the air conditioning system tends to accumulate dust, forming dirt that can lead to mold growth over time. 2. Avoid setting the air conditioning temperature too low. Prolonged exposure to low temperatures can cause various discomforts as the endocrine system may not adapt quickly. Normally, the cabin temperature should be adjusted to around 26~27 degrees Celsius. 3. Do not rest in the car with the engine running and air conditioning on. When the car engine is operating, incomplete combustion of gasoline in the cylinders can produce high concentrations of carbon monoxide, leading to poisoning or even death.
