1. The inspection and maintenance of the air bag must be carried out by the full-time maintenance personnel in strict accordance with the operating procedures specified by the manufacturer after carefully reading the manual attached to the vehicle. The personnel shall not disassemble and repair the air bag without permission, so as to avoid damage to the parts or danger.

2、检查维修气囊，要读取故障自诊断代码，然后脱开蓄电池电缆。

2. To check and repair the airbag, first read the fault self diagnostic code, and then disconnect the battery cable.

3、将点火开关转到OFF（或LOCK）位置，并将蓄电池负极端子电缆拆下90秒（有的车型为60秒）以上，然后再开始检修工作。因为气囊一般都配有备用电源，如果从蓄电池上拆下负极电缆后不到90秒（或60秒）就开始进行维修，气囊仍有可能充气张开。

3. Turn the ignition switch to the off (or lock) position, remove the negative terminal cable of the battery for more than 90 seconds (60 seconds for some models), and then start the maintenance work. Because the air bag is generally equipped with a standby power supply, if the maintenance is started less than 90 seconds (or 60 seconds) after the negative cable is removed from the battery, the air bag may still inflate and open.

4、当负极端子从蓄电池上脱开时，时钟和音响系统的存储内容都将消失。所以，在开始工作前，应将各存储系统的存储内容作好记录，在工作结束以后，对音响系统重新设置。

4. When the negative terminal is disconnected from the battery, the contents stored in the clock and audio system will disappear. Therefore, before starting the work, the storage contents of each storage system should be recorded, and after the work, the audio system should be reset.

5、如果发生轻微的碰撞，即使气囊并没有张开，也应仔细检查气囊、传感器、带收紧器、控制电脑以及电缆、插头等。

5. In case of slight collision, even if the airbag is not opened, carefully check the airbag, sensor, belt tightener, control computer, cable, plug, etc.
