• When the electric drive system is hot, its
cooling system is under pressure. Do not
open the expansion tank cap, hot coolant
may splash out and cause severe burns and
other injuries.
•
Turn the cap slowly and very carefully an-
ticlockwise while pressing it down slightly.
•
Always protect your face, hands and arms
from the hot coolant and steam with a
large thick cloth.
NOTICE
Only use distilled water! Other types of wa-
ter contain chemical substances that could
cause signicant corrosion damage. If you
have added non-distilled water, have all of
the drive system’s coolant changed immedi-
ately by a specialist workshop.
•
When topping up the, do not ll over the
upper edge of the marked area ››› Fig. 191.
Otherwise, when the temperature rises the
excess uid will be expelled from the motor
cooling system and could cause damage.
•
If the system leaks a lot of coolant, only
rell once the drive system has cooled down
completely. If there is a signicant loss of
coolant, there may be leaks in the cooling
system. Immediately go to a specialist work-
shop to have the system checked. This could
damage the drive system!
• Do not add coolant if the expansion tank
is completely empty! Air may have got into
the cooling system. Do not continue driving
and seek assistance from specialist person-
nel. This could damage the drive system!
•
When changing the operating uids, make
sure that you pour the correct uids into the
correct ller necks. Using the wrong operat-
ing uids can lead to serious malfunctions
and damage to the electric drive system.
