Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.

This light comes on when the ignition
is on, but the engine is not running,
as a check to show it is working. If it
does not, have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on
and stays on, when the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem
is apparent. Heeding the light can
prevent more serious damage to the
vehicle. This system assists the
service technician in correctly
diagnosing any malfunction.
Notice: If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle's fuel economy
might not be as good, and
the engine might not run as
smoothly. This could lead
to costly repairs that might
not be covered by the vehicle
warranty.
Notice: Modifications made
to the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead
to costly repairs not covered
by the vehicle warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test.
