Who ever thought that cars running across the road would one day become a "treasure" of cold knowledge.
With the improvement of the mass economy, cars have become a means of transportation with high popularity, and driving cars has become one of the skills that contemporary young people should have.
But being able to drive a car doesn't mean knowing the car. Even for some old drivers, the function of auto parts may not be clear.
The airbag has a long service life
Theoretically, the service life of the airbag is consistent with that of the whole vehicle, but it is not that long in practice. Although there is no clear shelf life, the quality of the airbag is difficult to guarantee even if it does not detonate after 8-10 years.
When the vehicle is started, there will be an OBD self-test process, including airbag system detection. The airbag indicator still flashes or remains on for 6-8 seconds after the vehicle is started, indicating that the airbag has failed and must be checked and handled in the 4S store in time.
There is also an "escape pod" in the car
Some - accidents may cause the body to deform and the doors and windows cannot be opened. At this time, escaping from the trunk may be a way.
Many models are equipped with switches in the trunk. In case of crisis, the personnel in the car can put down the rear seats, climb into the trunk and open the trunk through the switch to escape.
Why does the turn signal light make a "click"
When turning on the turn signal lamp or hazard warning flash lamp, it will make a "click sound", which is well known and used to.
But why don't low beam, high beam and fog lights? This is mainly because the use of turn signal lights or hazard warning flashers is mostly short. In order to avoid the driver forgetting to turn off, there will be a "click sound".
When the low beam lamp, high beam lamp and fog lamp are turned on, it usually takes a long time, and the sound will affect the driver. Therefore, only when the turn signal lamp or hazard warning flash lamp is turned on, the "click" sound will be made.
