Downloaded from www.Manualslib.com manuals search engine Engine Coolant Temperature Warning
Light
This red light tells you that
the engine has overheated.
You should stop the car and
turn the engine off as soon
as possible.
A warning
chime should also sound if
this light comes on.
As a check, the light should come on for a few seconds
when you start your engine. In the section “Problems on
the Road,” this manual explains what to do. See “Engine
Overheating’’ in the Index.
Malfunction Indicator Lamp
(Service Engine
Soon Light)
SERVICE
ENGINE
SOON
Your Cadillac 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 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.

Downloaded from www.Manualslib.com manuals search engine 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.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during
a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer
or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reduce vehicle speed.
0 Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as
soon as it is possible.
If the light stops flashing and remains on steady, see
“If the Light Is On Steady” following.
If the light continues
to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait
at least 10 seconds and restart the engine.
If the light remains on steady, see “If the Light Is On
Steady” following. If the light
is still flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light
off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel
(see “Fuel”
in the Index). Poor fuel quality will cause
your engine not to run as efficiently asdesigned.
You
may notice this as stalling after start-up, stalling when
you put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warned
up.)
This will be detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use.
It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light
goes on when you turn your key to RUN or
START.
It goes off once you start your engine. That’s a
check to be sure the light works. If it doesn’t come on,
be sure to have it fixed so it will be there to warn you if
something goes wrong.
When the light
comes on and stays on, it means that
oil isn’t flowing through your engine properly. You
could be low on oil and you might have some other
system problem.
A CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil
as soon as possible and have
your vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

temperature. Turn the TEMP knob clockwise to increase
the temperature and counterclockwise
to decrease
temperature. Adjust the fan speed as needed.
When the air conditioner .is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed to
cycle the compressor
on and off to keep the desired
temperature.
