Engine Coolant Temperature Gage; Malfunction Indicator Lamp - Cadillac 2001 Eldorado Owner's Manual

Engine Coolant Temperature Gage

That reading means the same thing as the warning
--
light the engine coolant has overheated. See "Engine
Overheating" in the Index.

Malfunction Indicator Lamp

(Service Engine Soon Light)
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area, the engine is
too hot.
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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 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. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
