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
and refilling coolant

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
