Low Oil Level Light; Change Engine Oil Light - Buick 2003 Century Owner's Manual

Low Oil Level Light
LOW
OIL
Your vehicle is equipped
with an oil level monitoring
system. When the
ignition key is turned on,
the LOW OIL light will
come on briefly.
If the light does not come on briefly, have it fixed so it
will be ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. See
Engine Oil on page
5-13. If the
light does not come on briefly, have the low oil level
sensor system repaired so it will be ready to warn you if
there's a problem.
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when
the engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for
a considerable period of time, allowing the oil normally
in circulation to drain back into the oil pan.
