case of combustion engines. F or this reason,
service fluids and consumables should be re-
placed at a qualified workshop. Volkswagen

changes. WARNING
Unsuitable service fluids and consumables,
and the incorrect use of these fluids and
consumables, can cause accidents, serious
injuries, burns or poisoning.
x Service fluids must be kept in their origi-
nal sealed container.
x Ne

ver store service fluids in empty food
containers, bottles or any other non-
original containers as people finding
these containers could drink them.
x Keep children away from all service flu-
ids and consumables.
x Always read and follow the information
and warnings on the service fluid pack-
aging.
x When using products that give off harm-
ful fumes, always work outdoors or in
a well-ventilated area. NOTICE
x Only use suitable service fluids f
or refilling.
Never use the wrong service fluid. Failure
to observe this warning can result in seri-

The washer fluid level should be checked reg-
ularly and refilled as necessary.
There is a strainer in the filler throat of the
washer fluid reservoir. The strainer keeps
large dirt particles away from the washer jets
when refilling. The strainer should only be re-
moved for cleaning. If the strainer is dam-
aged or is not present when refilling, dirt par-
ticles can enter the system and block the
washer jets.

window, considerably restricting the field
of vision.
NOTICE
x Ne ver mix suitable cleaning agents with
other cleaning agents. This can cause the
ingredients to separate and block the
washer jets. Coolant
Introduction to the topic
Do not work on the cooling system unless
you are familiar with the task, aware of the
general saf

ety procedures and have the cor-
rect equipment, service fluids and suitable
tools. Failing to carry out work correctly can
cause serious injuries

WARNING
Insufficient anti-freeze in the cooling sys-
tem of the v ehicle can cause the electric
drive to break down and thereby cause se-
rious injuries.
x The amount of correct coolant additive
used must be sufficient for the lowest
ambient temperature that you expect
the vehicle to be exposed to.
x Coolant can freeze at extremely cold
outside temperatures, causing the vehi-
cle to break down. Vehicle occupants
with inadequate winter clothing could
then freeze to death as the heating will
also no longer function. NOTICE
Never mix genuine coolant additives with
other coolants that ha
ve not been approved
by Volkswagen.
x If the liquid in the coolant expansion tank
is not pink (colouring results from mixing
the purple coolant additive with distilled
water) but for example brown instead of
purple, the suitable coolant has been
mixed with an unsuitable coolant additive.
The coolant must be changed as soon as
possible if this is the case. Failure to ob-
serve this warning can result in serious
malfunctions or damage to the electric
drive and cooling system. Coolant and coolant additives can pol-
lute the en

vironment. Spilt service flu-
ids must be collected and disposed of proper-
ly and with respect for the environment. Checking the coolant level

Preparations
1. Park the vehicle on a firm and level sur- face.
2. Allow the electric drive to cool down

cooling system when the engine is hot and
could cause damage.
x If a large amount of coolant has been lost,
do not refill the coolant until the engine
has cooled completely. Hea
vy coolant loss
is an indication of leaks in the cooling sys-
tem. The cooling system should be
checked by a qualified workshop as soon
as possible. Failure to do so can result in
engine damage.
x Do not refill coolant if there is no more
coolant in the coolant expansion tank. Air
could have entered the cooling system. Do
not drive on! Seek expert assistance. Fail-
ure to do so can result in engine damage.
x When refilling service fluids, please ensure
that you pour the correct service fluids in-
to the correct openings. The use of incor-
rect service fluids can result in serious
malfunctions and damage to the electric
drive. Troubleshooting
Please refer to , and on page 309

of someone drinking from such contain-
ers, even if they are labelled appropri-
ately.

original sealed container and kept out of
the reach of children. NOTICE
Brake fluid that has leaked or been spilt can
damage the v
ehicle paintwork, plastic parts

ment. Any spilt service fluids must be
cleaned up and disposed of properly. 12-volt vehicle battery
Introduction to the topic
The 12-
volt vehicle battery is a component of
the electrical system and in event of the
high-voltage system failing, supplies the
safety-relevant systems of the vehicle with
energy. In the scope of maintenance work,
the 12-volt vehicle battery is checked and
where required, replaced.
You should only carry out work on the electri-
cal system if you know exactly how to per-
form the required tasks, are aware of the
general safety procedures and have access to
the correct equipment, service fluids and
suitable tools. Failing to carry out work cor-
rectly can cause serious injuries
