High voltage! The voltage in the high-volt-
age system is high enough to cause fatal
injuries. Touching damaged high-voltage
components can result in a fatal electric

the high-voltage battery incorrectly can
result in serious injuries or death. The
high-voltage battery must only be serv-
iced by qualified and trained technicians.
Never make modifications to the high-
voltage battery. If the high-voltage bat-
tery is open, it must not come into contact
with water or other liquids. Liquids may
cause short circuits, electric shocks, and
burns.
Have the high-voltage battery replaced
only by an authorized Audi dealer or au-
thorized Audi Service Facility. Audi recom-
mends an authorized Audi dealer or au-

these locations have trained personnel
and the required parts and tools.
shock.
Electrolyte fluid is highly corrosive. Always
wear protective gloves and eye protection.
First aid: if electrolyte fluid enters the
eyes, immediately flush with clean water
for several minutes. Seek medical atten-
tion immediately. Immediately neutralize
electrolyte fluid on the skin or clothing us-
ing a soap solution and rinse with plenty
of water. Seek medical attention immedi-
ately if electrolyte fluid is ingested.
Always wear eye protection.
If electrolyte fluid enters the eyes, imme-
diately flush with clean water for several
minutes. Seek medical attention immedi-
ately.
WARNING
All work on the batteries must only be per-
formed by an authorized Audi dealer or au-
thorized Audi Service Facility.
Fire, sparks, open flame, and smoking are
prohibited. Avoid creating sparks and
short circuits when handling cables and
electrical devices.
– Gases that escape from these batteries can
be poisonous or flammable.
– The contents of these batteries can be corro-
sive. If any battery contents come into con-
tact with the skin, flush the affected area
with clean water for at least 15 minutes.
Then wash the affected area with soap. Have
the affected area examined by a medical
professional.
The high-voltage battery is flammable.
The high-voltage battery must never be
exposed to fire, sparks, or open flame. Al-
ways handle the high-voltage battery with
care to reduce the risk of damage and
leaking fluids.
Always keep children away from battery
electrolyte fluid and the battery.

form when charging batteries.
– Components must not be connected to the
battery terminals and wires on the 48 volt
battery because this increases the risk of
damage, for example due to overvoltage.
– Have maintenance work performed only by
trained personnel.
Applies to: high-voltage battery: Handling
the high-voltage battery incorrectly can
result in serious injuries or death. Never
remove the cover from the high-voltage
battery and never disassemble the high-
voltage battery.
– Have the 48 volt lithium battery replaced
only by an authorized Audi dealer or author-
ized Audi Service Facility. Audi recommends
an authorized Audi dealer or authorized
Audi Service Facility, because these loca-
tions have trained personnel and the re-
quired parts and tools.
