Cadillac deville 2000 ユーザーズマニュアル

Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a 
vehicle registration.

Here are some things you need to know in order to help
your vehicle pass an inspection:

Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE light is
on or not working properly.

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, see your dealer or qualified service center 
to prepare the vehicle for inspection.

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. It goes
off once you start your engine. That’s a check to be sure
the light works. If it doesn’t 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
isn’t flowing through your engine properly. You could
be low on oil and you might have some other 
system problem.
