Coolant level
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the coolant.
4-cylinder petrol and diesel engines: When
the cooling system is cold, the coolant level
in the expansion tank should be slightly
above the KALT/COLD mark. Coolant level
can be read off from the outside of the
expansion tank.
For V6 petrol and diesel engines, the
expansion tank must be opened in order to
check coolant level. When the cooling
system is cold, the coolant should be up to
the COLD mark on the filler opening.
When the engine is at operating
temperature, coolant level rises. It falls
again when the system cools. If it falls
below the KALT/COLD mark when the
system is cold, top up to the mark.
Top up antifreeze. If no antifreeze is
available, top up with clean tap water.
If tap water is unavailable, distilled water
can be used.
After filling with drinking water or distilled
water, measure the antifreeze
concentration and add antifreeze if
required. Have a workshop establish the
cause of the coolant loss.
Too low a coolant level can cause engine
damage.
To close, position the cap and screw it into
place.

Warning
Allow engine to cool down before
removing coolant filler cap. Remove filler
cap carefully so that pressure can escape
slowly, otherwise there is a risk of
scalding.
