Vehicle Electrical System, General Information

CAUTION:
- Risk of injury.
- Pay attention to stickers designating high voltage components. Prior to performing repairs, residual voltage must first be discharged.
- Some tools are supplied with a tool safety clip, which is slid over the tool points after using the tool, in order to protect other workers from injuries and tool points from damage.
- Observe country-specific requirements.
- By disconnecting battery ground (GND) wire, safe work on vehicle electrical system is guaranteed. With the ignition switched off, disconnect battery ground cable.
- Before starting a repair, the cause of the damage must be eliminated first, i.e. sharp edges on chassis parts, faulty consumers, corrosion etc.

NOTE:
- If possible, do not loosen ground (GND) straps from body (danger of corrosion).
- Further information, e.g. installing and removing the individual components, is described in the appropriate repair instructions.
