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 passenger com-
partment.
Checking the level
The coolant level must lie between the MIN and
MAX marks on the expansion tank. If the cooling
system is not filled sufficiently, excessively high
temperatures could occur, causing a risk of dam-
age to the engine.
NOTE
Check the coolant level regularly when the
engine is cold.
