GMC 2007 Acadia - Manual (Page 229)

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 comes 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.
Security Light
This light flashes
when the security
system is activated.
