Cadillac catera 2001 User Manual

This warning light should
come on for a few seconds
while you are starting the
engine. If the light doesn’t
come on, have it repaired.

Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle’s coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level
and add coolant as needed. The light should turn off as
soon as the coolant level is at its proper operating range.

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

Board

-

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.
