Malfunction Indicator Lamp - Chevrolet 2002 Prizm Owner's Manual

Engine Coolant Temperature Gage
Standard Cluster
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is too
hot! It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In "Problems on the Road," this manual shows what to
do. See "Engine Overheating" in the Index.

Malfunction Indicator Lamp

(Check Engine Light)
This system is called OBD II (On
-
Diagnostics Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
