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 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.

The engine oil pressure gage shows the engine oil pressure 
in psi (pounds per square inch) or kPa (kilopascals) when   
the engine is running.

Oil pressure should be 20 to 80 psi (140 to 550 kPa). In 
certain situations such as long, extended idles on hot days, it 
could read as low as 6 psi (40 kPa) and still be considered 
normal. It may vary with engine speed, outside temperature 
and oil viscosity, but readings above the shaded area show 
the normal operating range. Readings in the shaded area tell 
you that the engine is low on oil, or that you might have 
some other oil problem. See “Engine Oil” in the Index.

The engine oil pressure can also be displayed using the
GAGES button the the Driver Information Center
(DIC). See “Driver Information Center”in the Index.
