Anti-fr eeze a nd corrosion protect ion
Before the start of the cold weather season,
have the coolant checked by a workshop
for correct concentration. The amount of
anti-freez e m ust provide protection down
to approx. –28 °C. If the anti-freeze
concentration is too low, this reduces
protection from freezing and c orrosion.
Top up anti-freeze if necessary.
If coolant loss is topped up with
demineralised w ater, hav e a nti-freeze
concentration checked a nd more
anti-freez e ad ded as necessary.

Coolant lev el
Hardly a ny losses occur since the cooling
sy stem is sealed and it is thus rarely
necessary to top up the coolant.
The coolant lev el in the exp ansion tank
should be betw een the MIN and MA X
marks when the sy stem is cold. It rises at
engine operating tem perature and drops
again when the engine cools down.
If the level fa lls below the MIN mark, the
coolant m ust be rep lenished.

Warnin g
Allow engine to cool down before
removing c oolant filler cap. I f steam is
visib le, m ove away from the vehicle until
the eng ine is cool.
Remov e filler cap carefully so that
pressure can escap e slowly, otherw ise
there is a risk of scalding.
Top up w ith a mix of 56% demineralised
water a nd 44% anti-freez e specified for use
with y our v ehicle.
Do not use tap water, alcohol or methanol
anti-freeze to top up coolant level.
In extrem ely cold conditions, use a mix of
50% anti-freeze specified for use with your
vehicle a nd 50% demineralised water.
After topping up, have the anti-freeze
concentration check ed and anti-freeze
add ed if necessa ry . Elimina te the cause of
the coola nt loss. Consult a workshop.
When closing , tighten coolant filler ca p as
far as it will go.
