 Warnings and Precautions警告和注意事项

1. Important warning about air bags有关安全气囊的重要警告
  Warning:警告：
♦  Irregular or incorrect operations during the maintenance or replacement process may cause the airbag to explode accidentally, resulting in casualties or vehicle damage; at the same time, improper maintenance may also cause the airbag to fail. Therefore, only professionally trained technicians can repair and replace the airbag system.在维修或更换过程中若操作不规范或错误可能会造成安全气囊误爆，从而带来人员伤亡或车辆损坏；同时，维修不当也可能会造成安全气囊失效。因此，只有经过专业培训的技术人员才能对安全气囊系统进行检修、更换。
♦  Never use electrical equipment to operate any circuit of the air bag system except as described in this manual.除本手册说明的操作外，切勿使用电气设备对安全气囊系统的任何电路进行操作。
♦  When repairing the multi-function steering wheel, do not use a multimeter to check the resistance of the airbag, and do not knock or hit the airbag to prevent the airbag from accidentally exploding.检修多功能方向盘时，不能用万用表检查安全气囊的电阻，不能敲打或撞击安全气囊，以防止安全气囊误爆。
2. Important tips about airbags有关安全气囊的重要提示
  Note:提示：
♦  The backup power supply in the airbag electronic control unit is set up to keep the airbag function from failing after the power output of the car 12V battery is cut off. It consists of a power control circuit and several capacitors.气囊电子控制单元中的备用电源是在汽车蓄电池的电源输出切断后，为保持安全气囊功能不失效而设置的。它由电源控制电路和若干个电容器组成。
♦  The airbag and its connector adopt a short-circuit piece (copper spring piece) mechanism to prevent the airbag from accidentally exploding. Its function is that when the connector is pulled out, the short-circuit piece automatically shorts the two lead terminals of the plug or socket on the side close to the airbag ignition device. This structure can prevent static electricity or mistaken current from turning on the ignition circuit and causing the air bag to explode accidentally.安全气囊及其接插件均采用了防止气囊误爆的短路片(铜质弹簧片)机构。其作用是当接插件拔开时，短路片自动将靠近安全气囊点火装置一侧的插头或插座的两个引线端子短接。这种结构可防止静电或误通电将点火电路接通而造成气囊误爆。
♦  The airbag system circuit can be identified by the wiring harness or connector wrapped in yellow corrugated tubing.安全气囊系统电路可通过黄色波纹管包裹的线束或接插件来识别。
3. Important notes about air bags有关安全气囊的重要注意事项
  Caution:注意：
♦  It is difficult to confirm the fault of the airbag system. The fault code in the memory of the self-diagnosis system is an important source of information for troubleshooting. Therefore, before checking and troubleshooting airbag faults, you must read the fault code before removing the negative 12V battery cable.安全气囊系统的故障很难确认，自诊断系统在存储器中的故障代码是排除故障的重要信息来源。因此在检查与排除安全气囊故障前，必须在拆下蓄电池负极电缆前，读取故障码。
♦  The inspection needs to be done after adjusting the power status to "OFF" and disconnecting the negative terminal of the 12V battery for 90 seconds or more. There is a backup power supply in the airbag electronic control unit. If the 12V battery terminal is removed and checked within 90 seconds, the airbag may explode accidentally.检查工作需调整电源状态为“OFF”，且断开蓄电池负极端子90s或更长时间后进行。安全气囊电子控制单元中有备用电源，若拆下蓄电池端子后90s内进行检查，则可能使安全气囊误爆。
♦  The airbag system has high requirements on parts, and all parts are single-use parts. Damaged airbag related parts must not be repaired or used. Airbag related components include collision sensors, driver airbags, passenger airbags, seat belt pretensioners, side air curtains, airbag electronic control units, passenger detectors, etc.安全气囊系统对零部件的要求较高，所有零部件均为一次性使用部件。对损坏的安全气囊相关部件绝不能修复使用。安全气囊相关部件包括碰撞传感器、驾驶员安全气囊、副驾驶员安全气囊、安全带预紧装置、侧气帘、气囊电子控制单元、副驾驶探测器等。
♦  When the vehicle is hit by a collision, the airbag has been detonated, and the driver airbag cover and passenger airbag cover have been scratched, cracked or otherwise damaged, the airbag or collision sensor needs to be replaced immediately.当车辆受到碰撞、安全气囊已经引爆，驾驶员气囊盖、副驾驶员安全气囊盖已经刮破、裂开或有其他损坏时，需立刻更换安全气囊或碰撞传感器。
♦  During maintenance, do not change, disassemble, knock or open any components, such as the steering wheel, driver's airbag cover, passenger airbag or airbag electronic control unit and sensor assembly, otherwise the airbag will suddenly inflate or the system will lose its function.在维修时不能改变、拆卸、敲击或打开任何组件，例如方向盘、驾驶员安全气囊盖、副驾驶员安全气囊或气囊电子控制单元及传感器组件，否则将造成气囊突然充气或系统失去作用。
♦  When disassembling or transporting airbag components, the decorative cover side of the airbag should be facing up. Airbag components should not be stacked on top of each other to prevent accidental explosion of the airbags and serious accidents.拆卸或搬运安全气囊组件时，气囊装饰盖一面应当朝上，不得将安全气囊组件重叠堆放，以防止气囊误爆而造成严重事故。
4. Important notes about impact sensors有关碰撞传感器的重要注意事项
  Caution:注意：
♦  Crash sensors are single use and do not allow for repair.碰撞传感器都为一次性使用，不允许修复。
♦  If the airbag explodes after a collision, the left and right front collision sensors should be replaced at the same time.碰撞后若气囊爆出，左前和右前碰撞传感器应同时更换。
♦  When replacing the collision sensor, you should use new products and do not use parts from other vehicles of different models.更换碰撞传感器时，应使用新品，不能使用其他不同型号车辆上的零部件。
♦  When installing the collision sensor, pay attention to the direction of the arrow on the sensor housing and install it in the specified direction.安装碰撞传感器时，应注意传感器壳体上的箭头指向，必须按规定方向安装。
