Cadillac 2007 STS Automobile User Manual


 
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 the
battery or if the 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 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 equipped, this light
tells you if there could be
a problem with your
engine oil pressure.
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.
