Closing the bonnet
X
Lower the bonnet and let it fall from a
height of approximately 20 cm.
X
Check that the bonnet has engaged prop-
erly.
If the bonnet can be raised slightly, it is not
properly engaged. Open it again and close
it with a little more force.
Radiator
Do not cover up the radiator. Do not use ther-
mal mats, insect protection covers or any-
thing similar. Doing so can cause the Onboard
Diagnostics System to display inaccurate val-
ues. Some of these values are legally required
and must always be correct.
Engine oil
General notes
Depending on your driving style, the vehicle
consumes up to 0.8 litres of 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.
Depending on the engine, the oil dipstick may
be installed at 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. if the engine was only
started briefly, wait approximately
30 minutes before carrying out the meas-
urement.
