Coolant - level
The coolant cools the internal combustion
engine to the correct operating temperature.
The heat that is transferred from the engine to
the coolant can be used to heat the passen-
ger compartment.
The coolant level must lie between the MIN
and MAX marks on the expansion tank.
Checking the level and topping up
When topping up the coolant, follow the
instructions on the packaging. It is important
that the mixture of coolant concentrate and
water is correct for the prevailing weather
conditions. Never top up with water only. The
risk of freezing increases with both too little
and too much coolant concentrate.
