Safety precautions and repair instructions for vehicles with hybrid drive
DANGER!
Risk of fatal injury if high-voltage components are damaged.
Observe the following when working in the vicinity of high-voltage components or wiring:
It is not permitted to use cutting or forming tools, other sharp-edged tools or heat sources such as welding, brazing, soldering, hot air or thermal bonding equipment.
Before starting work, visually inspect the high-voltage components in the areas involved.
Before working in the engine compartment, visually inspect the
power and control electronics for electric drive

,
air conditioner compressor

and high-voltage wiring.
Before working on the vehicle underbody, visually inspect the high-voltage wiring and covers.
Before working on the rear section of the vehicle, visually inspect the high-voltage wiring and the electro-box with the
maintenance connector for high-voltage system

.
Visually inspect all potential equalisation lines.
Check the following when making the visual inspection:
There must be no external damage on any component.
The insulation of the high-voltage wiring and potential equalisation lines must not be damaged.
There must be no unusual deformation of the high-voltage wiring.
All high-voltage components must be identified by a red warning sticker.
WARNING
Working on vehicles with high-voltage wiring:
Do not support yourself or tools on high-voltage wiring or associated components --> this can damage the insulation.
High-voltage wiring must not be excessively bent or kinked --> this can damage the insulation.
The round high-voltage connectors are colour-coded with an external coloured ring and are provided with mechanical coding or guide lugs. It is important to observe this coding when joining up the round high-voltage connectors, otherwise the connectors can be damaged.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
