An airbag is an auxiliary safety protection device that can only function effectively when used in conjunction with seat belts. The airbag is an application system - what we commonly see as deployed airbags are merely the execution units of this system. A crucial component of the airbag system is the ECU (Electronic Control Unit, commonly known as the airbag computer). This computer is installed at a specific location on the vehicle floor, where it detects and analyzes collision signals from the front of the vehicle to determine whether to deploy the airbag. If the analysis indicates a severe collision requiring airbag deployment, the airbag computer will issue an ignition command to activate the airbag module through wiring harnesses, thereby protecting the occupants.

What is each gear of a manual transmission and how to use it?

Manual transmission's first gear is the starting gear; second gear is the passing gear; third gear is the transition gear; fourth gear is the driving gear; fifth gear is the high-speed gear. Usually, when starting the car, you need to engage first gear, but this gear is not suitable for continuous high-speed operation. Once the car has momentum, shift to second gear, which is the passing gear suitable for various complex road conditions, such as areas with heavy pedestrian traffic or bumpy sections. Third gear is a transition gear, mainly used for low-speed driving in urban areas. Once traffic conditions improve and acceleration is needed, you can transition to fourth gear. If deceleration is required, shift back to second gear. Fourth gear is the driving gear, used for prolonged high-speed driving. Fifth gear is used for long-distance driving on highways.
