EMISSIONS INSPECTION
AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal require-
ment to pass an inspection of your vehicle's
emissions control system. Failure to pass
could prevent vehicle registration.
Normally, the OBD II system will
be ready. The OBD II system may
notbe ready if your vehicle was
recently serviced, recently had a dead battery
or a battery replacement. If the OBD II sys-
tem should be determined not ready for the
I/M test, your vehicle may fail the test.Your vehicle has a simple ignition actuated
test, which you can use prior to going to the
test station. To check if your vehicle's OBD II
system is ready, you must do the following:
1. Cycle the ignition switch to the ON posi-
tion, but do not crank or start the engine.
NOTE:
If you crank or start the engine, you will
have to start this test over.
2. As soon as you cycle the ignition switch to
the ON position, you will see the “Mal-
function Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of
two things will happen:
• The MIL will flash for about ten seconds
and then return to being fully illuminated
until you turn OFF the ignition or start the
engine. This means that your vehicle's OBD
II system isnot readyand you shouldnot
proceed to the I/M station.• The MIL will not flash at all and will remain
fully illuminated until you place the igni-
tion in the off position or start the engine.
This means that your vehicle's OBD II sys-
tem isreadyand you can proceed to the I/M
station.
If your OBD II system isnot ready,you should
see an authorized dealer or repair facility. If
your vehicle was recently serviced or had a
battery failure or replacement, you may need
to do nothing more than drive your vehicle as
you normally would in order for your OBD II
system to update. A recheck with the above
test routine may then indicate that the sys-
tem isnow ready.
Regardless of whether your vehicle's OBD II
system is ready or not, if the MIL is illumi-
nated during normal vehicle operation you
should have your vehicle serviced before go-
ing to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the
engine running.

• When performing any operation on the
battery or near it, always protect your
eyes with special goggles.
• Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an autho-
rized dealership.
• Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump Starting Proce-
WARNING!
dure” in “In Case Of Emergency” for
further information.
