Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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. The
CHECK ENGINE light comes on and
a chime will sound 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.

on, after a while, your emission controls may not
work

good and your engine may not run as smoothly.

costly repairs not covered by your warranty.
