Before and during the welding or soldering work always observe the following measures, to avoid any damage to the vehicle components:
1 Disconnect ignition key and disconnect/insulate ground line from battery.
2 When performing electric welding or soldering work in area of airbag control units (distance < 0.5 m), disconnect electrical connector from airbag control unit.
3 The high-voltage battery, gas cylinder and gas-related components must not exceed a temperature of > 60 °C.
4 Before welding or soldering, cover all components to protect against flying sparks and radiant heat or remove from hazardous area (including lines and components in hollow cavities).
5 Do not touch electronics housings or electrical lines with welding electrode or ground line from the welder or solder.
6 Directly connect ground terminal from electrical welding and soldering unit to component to be welded or soldered. When doing so, ensure that there are no electrically insulating parts between the ground terminal and the welding or soldering point.
7 Do not connect ground terminal from electrical welding or soldering unit to major assemblies (e.g. transmission, engine, etc.).
