MALFUNCTION
INDICATOR LIGHT
After the ignition switch is turned to
II/ON position and before the engine is
started, the indicator light will
illuminate.
This shows that the indicator light bulb
is working correctly.
When the engine is started, this warning
light will go off.
Caution
Malfunction indicator light indicates
that your vehicle has some fault that
requires your attention. Driving while
the Malfunction Indicator Light is on
may damage the emission control
system, affecting fuel economy and
the vehicle's driveability.
Consult your CHEVROLET retailer
as soon as possible for repair .
If the emission-related components or
relevant subsystems have a fault, the
Malfunction Indicator Light (MIL) will
illuminate.
As long as the electronic control
module (ECM) detects a fault, the
Malfunction Indicator Light will
illuminate continuously.
A serious misfire may damage the
catalytic converter.
The electronic systems on the vehicle
will switch to an emergency operation
program so that you can continue to
drive the vehicle.
However, at this time you should drive
to your CHEVROLET retailer as soon
as possible.
If the MIL illuminates for a while then
extinguishes itself, it is normal. It does
not mean that the system has a fault.
Caution
Modifications made to the engine,
transmission, exhaust, intake, or fuel
system of the vehicle or the replace-
ment 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.
