What does the sync button in the car mean?

[DiGenesis]

The sync button in the car means: 1. Function synchronization: It refers to the synchronization of functions, generally used for car air conditioning. 2. Sync button: It is a dual-zone synchronous temperature control button. After releasing it, different temperature settings can be achieved for the left and right dual-zone air conditioning. Precautions for using car air conditioning: 1. Regularly clean the air conditioning: During use, the air conditioning often inhales a certain amount of dust, forming dirt. After a long time, mold may develop. 2. The air conditioning temperature should not be too low: When the indoor temperature remains at a relatively low temperature for a long time, the body cannot quickly adapt due to the endocrine system, leading to various discomforts. 3. Do not stop and rest with the air conditioning on: When the car engine is running, if the gasoline in the cylinders does not burn completely, it will produce a high concentration of carbon monoxide, which can cause poisoning or even death.
