DANGER
Due to the high-voltage technology, electrical
lines and components which operate under high
voltage are used in the vehicle. Accordingly,
work on the vehicle may only be performed by
specially trained mechanics.
Special care must be taken at all areas of the
vehicle which are linked to the high-voltage
system e.g. parts in the engine compartment.
Orange-coloured lines and their connectors
conduct high-voltage and may not be damaged.
You could be seriously or fatally injured if you
• Remove covers from components which are
identified with a warning sticker
• Tamper with components of the high-voltage
on-board electrical system
• Open housings
• Disconnect connectors
• Touch components or orange-coloured lines
of the high-voltage on-board electrical
system on a vehicle involved in an accident
• Touch damaged orange-coloured lines or
their damaged connectors
• Touch damaged components of the high-
voltage on-board electrical system.
