Damage to the v ehicle or to the high-
voltage battery could lead to a leak of
toxic gases or fluids, either immediately
or at a later time. These emitted gases
could also potentially cause a fire. Do
not inhale these gases.
x Never touch the fluids that leak from the
high-voltage battery.
x In the event of a fire, move away from
the hazard area and call the fire service.
x Always inform any attending fire and
emergency services that the vehicle is
fitted with a high-voltage battery. NOTICE
After an accident, or after the underside of
the v
ehicle has struck an obstacle, the high-
voltage battery must be checked by appropri-
ately qualified and trained experts. Warning signs for the high-
v

high-
voltage battery Introduction to the topic
Reliability and capacity of the high-
voltage
battery
Lithium-ion batteries are subject to a physical
and chemical ageing and wear process during
their useful life. Correct handling of the high-
voltage battery makes a significant contribu-
tion to maintaining its reliable condition and
a high useful capacity and range in the long
term. It is therefore all the more important to
observe the following care instructions for
the high-voltage battery. These care instruc-
tions form the basis for long value retention
of the vehicle.
Please also observe the valid Volkswagen
warranty and guarantee terms for the high-
voltage battery. Care instructions for the high-voltage battery 275

Handling the high-voltage
battery
Care instructions
V
olkswagen recommends observing the fol-
lowing care instructions:

Upper battery charge limit
F
ull charging of the high-voltage battery is
not normally necessary in daily vehicle use.
The upper battery charge limit limits the
maximum charge level.

WARNING
Driving when the charge level of the high-
v oltage battery is too low can lead to the
vehicle breaking down when in traffic, and
can lead to accidents and serious injuries. The high-voltage battery can only be
charged at charging stations that meet
the requirements of the corresponding coun-
try and at least the f

ollowing standards:

x
Ne ver charge a 12-volt vehicle battery
which is frozen or has been frozen. Dis-
charged 12-volt vehicle batteries can al-
ready freeze at temperatures of around

All work on the 12- volt vehicle battery
and the electrical system can cause seri-
ous chemical burns, fire or electric
shocks. Always read the warnings and
