Is there a line on the car glass? Many people may not have noticed this. Of course, it may be that some people have noticed it, but they do not know where to come from, nor do they know what role they have, and some people even think that it was carried on a film. In fact, these lines are the original resistance wires on the rear windshield. They aren't carried by the car's film, but they look more obvious when they are attached to the car's film. It has a great effect on safe driving, especially in autumn and winter. In winter, the temperature difference between the outside of the car is generally relatively large, or in the rainy season, it is very easy to condense into a layer of frost or water vapor on the windows of the car, so that the riders sit in the car. Can not see the scene outside the car, but in the process of reversing or some driving, you need to pay attention to the situation behind the car at any time. At this time, the line on the rear windshield of the car plays a key role, but it needs to be used in conjunction with the defrosting button in the car, which causes the frost or water vapor on the window glass to evaporate through the heating of the resistance wire. In this way, you can see very clearly when you look out of the glass behind the car. The button is located next to the air conditioning and internal circulation buttons, and some owners do not know its function. According to a 4S shop official, among the owners he touched, the defrosting button was mistaken for a large number of external cycle buttons, and most of them didn't understand what the line was on the rear windshield. However, it is necessary to remind everyone that the defrost button can only be pressed when fogging or defrosting, and it must be used after the vehicle is started. Otherwise, it will consume power, which is not good for the car battery. The resistance wire on the rear windshield must be used with the defrost button. Editor's comment: Still complaining about not seeing the rear case? Correct use of these lines that have been overlooked by you, so that fog and frost quickly dispersed, will also give you a clear rear sight. Care should also be taken when washing or caring. It is important to avoid scratches and damage.
