Engine ventilation heating: Notes
WARNING: This page is about a different variant/trim than selected.
When the engine is cold, the engine ventilation heating prevents ice formation from freezing condensation within the engine ventilation.
If freezing occurs in the engine ventilation system, the pressure in the crankcase may increase. This may cause engine oil to be burnt or pushed past gaskets out of the engine. The oil loss can lead to total destruction of the engine.
