Engine oil
Depending on driving style, the vehicle consumes a maximum of 0.8 l oil per 1,000 km. The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds. You can only estimate the oil consumption after you have driven a considerable distance.
You will find further information about engine oil in the "Technical data" section more.
Checking the engine oil level
To do so:
-
the vehicle should be parked on level ground.
-
the engine should be switched off for at least five minutes if the engine was at normal operating temperature.
-
the engine should be switched off for at least 30 minutes if the engine was not at operating temperature (i.e. if you only started the engine briefly).

Use
-
a windscreen washer fluid additive such as MB Summerwash to prevent smearing (for temperatures above freezing).
-
a windscreen washer fluid additive with antifreeze properties such as MB Winterwash (if there is a risk of frost).
