Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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 you what
to do. See "Engine Overheating" in the Index.
This system is called OBD I1 (On-Board
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. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON 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, which may prevent more serious damage
to your vehicle. This system is also designed to assist
your service technician in correctly diagnosing
any malfunction.
