consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.

kmay
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g .ifthe engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
