Light)
CHECK
ENGINE
Your Oldsmobile 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.
(In
Canada,
OBD
I1
is replaced by
Enhanced Diagnostics.) 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.
