Working on vehicles with high-voltage system (hybrid vehicles)
High voltage! Danger to life!
The voltage levels in the high-voltage system constitute a safety
hazard. Danger of severe or fatal injuries from electric shock.
– Persons with life-sustaining or other electronic medical devi‐
ces in or on their body must not perform any work on the high-
voltage system. Such medical devices include internal anal‐
gesic pumps, implanted defibrillators, pacemakers, insulin
pumps and hearing aids.
– The high-voltage system must be de-energised by a suitably
qualified person.

It is difficult to determine whether the drive system of an electric
vehicle or hybrid vehicle is active. Moving parts can trap or draw
in parts of the body.
– Switch off ignition.
– Place ignition key outside vehicle.
Risk of damage to high-voltage wiring
Incorrect handling may result in damage to the insulation of high-
voltage wires or high-voltage connectors.
– Never use high-voltage wiring or high-voltage connectors as
a support.
– Never prop tools against high-voltage wiring or high-voltage
connectors.
– Never bend or kink high-voltage wiring.
– Pay attention to coding when connecting high-voltage con‐
nections.
