Criteria for warning
The visual oil pressure warning switches on (oil pressure warning
lamp lights up continuously) and the acoustical warning buzzer
sounds three times under any one of the following conditions.
• “Ignition on”, engine not running, oil pressure switch closed
• Engine revolutions above 1500 rpm, oil pressure switch open
Note
♦
At an engine speed above 5000 rpm, the warning lamp will still
remain on when the oil pressure switch is closed. The warning
lamp will be switched off again if the engine revolutions are
below 5000 rpm.
♦
If the oil pressure switch is only open for 0.3…3.0 seconds at
an engine speed above 1500 rpm, this will be stored in the
combination processor of the dash panel insert. If this condi‐
tion occurs three times while the engine is running, the oil
pressure warning will be activated immediately and will not be
cancelled even below 1500 rpm. The oil pressure warning will
be cancelled when the oil pressure switch is closed for longer
than 5 seconds at an engine speed above 1500 rpm or when
the ignition is switched off.
