ture.
If oil pressure drops abruptly and a message
is displayed on the on-board computer when
the engine is running on or when driving:
f Stop immediately in a suitable place.
f Switch off the engine.
f Check whether there is an obvious oil leak on
or under the car.
f If no oil leak can be detected: With the engine
idling, measure the oil level with the on-board
computer.
f Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
