Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
The vehicle will not pass this inspection if the OBD II
(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 the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Gage (US-Canada)
For vehicles with an engine oil pressure gage, it shows
the engine oil pressure in psi (pounds per square inch)
when the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure can vary with engine speed, outside
temperature and oil viscosity, but if readings are outside
the normal operating range, the oil pressure light
comes on. SeeOil Pressure Light on page 3-49for
more information.United States
Canada
3-48

Page 233 of 602

A reading outside the normal operating range can be
caused by a dangerously low oil level or some other
problem causing low oil pressure. Check the vehicle’s oil
as soon as possible. See “OIL PRESSURE LOW” under
DIC Warnings and Messages on page 3-66andEngine
Oil on page 5-17.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

Here are some situations owners can experience with
the fuel gage. None of these indicate a problem with the
fuel gage.
At the gas station, the fuel pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the fuel tank’s
capacity to ll it.
The gage goes back to empty when the ignition is
turned off.
For a diesel engine, see “Fuel Gage” in the Diesel
Engine Supplement.
Low Fuel Warning Light
This light, under the fuel
gage, comes on briey
while the engine is being
started.
This light and a chime comes on when the fuel tank is low
on fuel. The Driver Information Center also displays a
“FUEL LEVEL LOW” message. SeeDIC Warnings and
Messages on page 3-66for more information. When fuel
is added this light and message should go off. If it does
not, have the vehicle serviced by your dealer/retailer.
