The door was unlocked when I first touched it, but now it doesn't respond. What is the reason? Questioner: Yan's best answer is that there are two buttons on the door, which are open and closed locks, and the icons correspond to the corresponding functions. Automatic locking while driving. Empty press the on key in the regulation area, and then turn on the auto key to start the automatic constant temperature function, which will automatically adjust the air volume according to the temperature. Turn the temperature knob to adjust the driver's position and the auxiliary driving position. Use the villain button to turn the knob to adjust the position of the air outlet, and the position of the air outlet will be displayed on the main display screen.
