Oil Pressure Light; Security Light - GMC 2007 Yukon Denali Owner's Manual

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 will come on
briefly when 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.
