Cooling system
Coolant
The engine cooling system is filled at the fac-
tory with a mixture of conditioned water and
coolant additive. This coolant must not be
changed.
The coolant level is monitored by a warning
lamp in the instrument
cluster ~ page 20.
However, we recommend that it should be
checked occasionally .
If you do need to top up the coolant, use a
mixture of water and coolant additive. We rec-
ommend mixing coolant additive with distil-
led water.
Coolant additive
The coolant add itive contains anti-freeze and
corrosion protection agent. Only use one of
the following coolant additives. It is possible
to mix these additives.

The amount of coolant additive which needs
to be mixed with the water depends on the
temperatures to be expected in the winter
season. If the anti-freeze concentration is too
low, the coolant can freeze and cause eng ine
damage.
