Overview of the high-voltage system  
The high-voltage system consists, among other things, of the following components:  
High-voltage battery.  
Power electronics.  
Electric motor.  
High-voltage air conditioning compressor.  
Charger for high-voltage battery.  
Charging socket for high-voltage battery.  
Orange-coloured high-voltage cables and connectors.  
High voltage heater.  
All work on the high-voltage system must be carried out by a professional workshop with  
appropriately qualified and trained personnel, in accordance with the Volkswagen Guidelines (→ In  
the engine compartment, General safety) →  
.
Warning signs and stickers (→ Information stickers and plates, Description).  
General warning signs for high voltage  
Warning signs for high voltage Fig. 1  
and indicate the presence of high voltage . The  
following vehicle components may be marked with these warning signs:  
Covers and caps over high-voltage components.  
All high-voltage components including the high-voltage battery.  
Lock carrier in the engine compartment.  
Warning sign on the high-voltage battery  
There is a warning sign on the high-voltage battery that warns about the dangers of high voltages  
.
Key to Fig. 1  
:

High voltages can cause serious injuries or death. Never touch the battery terminals with your  
fingers, tools, jewellery or any metal objects.

The high-voltage battery contains dangerous liquid and solid substances. Serious chemical  
burns and blindness can be caused if it outgasses. Suitable eye protection and protective  
clothing should always be worn when performing work on the high-voltage battery to prevent  
the battery fluid coming in contact with skin and eyes. If skin or eyes come into contact with  
battery fluid, rinse the affected areas with clean flowing water for at least 15 minutes and seek  
a doctor immediately.  
The high-voltage battery can burn. The high-voltage battery must never be exposed to fire,  
sparks or naked flames. Always handle the high-voltage battery with care to avoid damage and  
fluid leaks.

Always keep children away from the high-voltage battery.  
You will find further information and warnings in the owner's manual and in the workshop  
literature.

Incorrect handling of the high-voltage battery can cause serious injuries or death. Under no  
circumstances remove the lid from the high-voltage battery nor disassemble the high-voltage  
battery.  
Incorrect handling of the high-voltage battery can cause serious injuries or death. Have  
maintenance work on the high-voltage battery performed exclusively by properly qualified and  
trained specialist staff . Never make modifications to the high-voltage battery. The opened  
high-voltage battery must not come into contact with water or other liquids. Liquids can cause  
short-circuits, electric shocks and burns.  
DANGER  
The vehicle's high-voltage network and the high-voltage battery are dangerous and can cause  
burns or other injuries and even lead to a fatal electric shock.  
You should always assume that the high-voltage battery is fully charged and that all high-  
voltage components are live. This can also be the case when the electric drive is switched off  
and the ignition is switched off.  
Never touch high-voltage cables, the high-voltage battery or the poles of the high-voltage  
battery, and never touch these with jewellery or other metal objects, in particular if the high-  
voltage cable, high-voltage battery or high-voltage battery poles are damaged.  
Never attempt to carry out any work on the high-voltage network, the high-voltage cables or  
the high-voltage battery.  
Never open, maintain or repair components or parts of the high-voltage network, and never  
disconnect them from the network.  
Never damage, change or remove the orange-coloured high-voltage cables or disconnect them  
from the high-voltage network.  
Never open, modify or remove the cover of the high-voltage battery.  
Any work on the high-voltage system, or on systems which could be indirectly affected by it,  
must only be carried out by properly trained and qualified expert personnel.  
Work in the vicinity of high-voltage components and high-voltage cables with machining,  
shaping and sharp-edged tools or heat sources, for example, welding, soldering, hot air or  
thermal adhesives, may only be performed after the vehicle has been de-energised. Only  
properly qualified and trained specialist staff may de-energise the vehicle.  
The Volkswagen standards and guidelines must be adhered to when carrying out any work on  
the high-voltage system or the high-voltage battery.  
Store the vehicle key in a safe place far enough away from the vehicle to prevent any risk of the  
ignition being switched on accidentally.  
Any gases emitted by or escaping from the high-voltage battery may be toxic or flammable.  
Damage to the vehicle or to the high-voltage battery could lead to a leak of toxic gases, either  
immediately or at a later time. These emitted gases could also potentially cause a fire. If  
damage has been incurred, it is vital to then open the vehicle windows to allow any emitted  
gases to disperse. Do not inhale these gases.  
Never touch any liquids or expose yourself to any gases leaking from the high-voltage battery,  
especially if the battery has been damaged.  
In the event of a fire, move away from the hazard area and call the fire service. Inform the fire  
service that the vehicle in question has an electric drive.  
Remember to inform any attending emergency services that the vehicle is fitted with a high-  
voltage battery.  
WARNING  
Unqualified work on the high-voltage system and on high-voltage components can lead to  
malfunctions, accidents and injuries.  
Any work on the high-voltage system, or on systems which could be indirectly affected by it,  
must only be carried out by properly trained and qualified expert personnel.  
WARNING  
An electric vehicle does not generate any operating noise when stationary and produces only low  
noise when driving. Other road users, such as pedestrians and children, may therefore have  
difficulty hearing or detecting the electric vehicle. This can result in accidents and injuries, for  
example when driving in traffic-calmed areas, when manoeuvring the vehicle or when driving in  
reverse.  
NOTICE  
After an accident, or after the underside of the vehicle has struck an obstacle, the high-voltage  
battery must be checked by appropriately qualified and trained experts.
