Cadillac 2004 Seville - Manual (Page 161)

Oil Pressure Light
{ CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice: Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON or
START. It goes off once you start your engine. That is a
check to be sure the light works. If it does not come
on, be sure to have it fixed so it will be there to warn you
if something goes wrong.
When the light comes on and stays on, it means that oil
is not flowing through your engine properly. You
could be low on oil and you might have some other
system problem.
