Cadillac 2006 CTS, Owner'S Manual

Page: 174 / 442

Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
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.
If your vehicle has this
light, it will come on when
there is a problem with
your engine oil pressure.
This light will come on when you turn your key to ON or
START. It goes off once you start the 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
there is a problem.
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. See
Engine Oil on page 5-16 for more
information.
