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. See Accessories and Modific-

ations on page 9-2.

Caution

If the vehicle is continuously driven

with this light on, the emission

controls might not work as well, the

vehicle 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.

MALFUNCTION

INDICATOR LAMP

A computer system called OBD (On-

Board Diagnostics) monitors operation

of the fuel, ignition, and emission control

systems. It ensures 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

retailer.

If the check engine light comes on and

stays on while the engine is running,

this indicates that there is an OBD

CHEVROLET

problem and service is required.

Malfunctions often are indicated by the

system before any problem is apparent.

Being aware of the light can prevent

more serious damage to the vehicle. This

system assists the service technician in

correctly diagnosing any malfunction.

This light comes on during a malfunc-

tion in one of two ways:

Light Flashing: A misfire condition has

been detected. A misfire increases vehicle

emissions and could damage the

emission control system on the vehicle.

Diagnosis and service might be required.

The following can prevent more serious

damage to the vehicle:

Ÿ Reduce vehicle speed.

Ÿ Avoid hard accelerations.

Ÿ Avoid steep uphill grades.
