Replace cap

and turn it clockwise until it
engages.
#
Check the oil level again. Check using the on-
board computer (
/
page 214), check with the
oil dipstick (
/
page 215).
#
In the case of vehicles with engines that do not
have an oil dipstick, check the oil level with the
on-board computer after the next journey
(
/
page 214).
It is necessary to run the engine for an extended
period after each oil top-up to correctly detect the
oil level. Fill level changes during oil top-ups may
not be immediately visible. Depending on the driv-
ing profile, the new oil level can only be displayed
after a driving time of up to 60 minutes.
To avoid damage due to overfilling, do not add
more than 0.26 gal (1 liter).
Check the oil level again after a longer period.
