Brake uid
●
When the motor is hot, its cooling system is
pressurised. 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 motor cooling system uid changed im-
mediately by a specialist workshop.
●
When topping up the, do not ll over the
upper edge of the marked area ›››Fig.193.
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 motor has cooled down com-
pletely. If there is a signicant loss of coolant,
there may be leaks in the cooling system. Im-
mediately go to a specialist workshop to have
the system checked. This could result in mo-
tor damage.
●
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 result in motor damage.
●
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 motor damage.

Checking the brake uid level
The brake uid level must be between the
and markings.
However, if the brake uid level goes down no-
ticeably in a short time, or drops below the
mark, there may be a leak in the brake sys-
tem. Seek specialist assistance. A warning light
on the instrument panel display monitors the
brake uid level.
Brake uid level
The control lamp lights up red.
Brake uid level is too low.
●
Stop driving!
●
Check the brake uid level.
●
If the brake uid level is too low, seek special-
ist assistance.
Changing brake uid
We recommend that you have the brake uid
changed by a Technical Service.
WARNING
If the brake uid level is low or unsuitable/old
brake uid is used, the brake system may fail
or braking power may be reduced.
●
Check the brake system and the brake uid
level regularly!
●
When the brake uid is used and brakes are
subjected to extreme braking forces, bub-
bles of vapour form in the brake system.
These bubbles can signicantly reduce brak-
