61 35... Notes on ESD protection (Electro Static Discharge)

WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2007 BMW M5, and 2007 BMW 530xi. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Electrical components which are particularly sensitive to electrostatic discharge (electronic control units, sensors, etc.) are marked with the ESD warning symbol.

-Electro

-Static

-Discharge

Statically charged persons can discharge by touching electrical components.

NOTE: Humans can only detect a discharge starting from a level of approx. 3000 V.

The danger threshold for electrical components already starts from a level of approx. 100 V.

IMPORTANT: Do not touch pins or multi-pin connectors directly!

Touch electrical components by their housings only.

IMPORTANT: To prevent electrical components from being damaged or destroyed by electrostatic discharge, it is absolutely essential to comply with the following instructions:

Personal protective equipment: 

Electrically conducting clothing (high wool content, antistatic shoes required).

These can primarily be identified by the logo on the side.
