close it with a little more force.
Engine oil
Depending on driving style, the vehicle con-
sumes 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
( page 358).

mal operating temperature.
the engine should be switched off for at
R
least 30 minutes if the engine was not at
222
operating temperature (i.e. if you only star-
ted the engine briefly).
