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.
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:
Light FIashing -- 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.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing’
The following may prevent more senous damage to
your vehicle:
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
e Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
0 If towing a trailer, reduce the amount of cargo being
hauled as soon as
it is possible. 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.
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. FW 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.

Have you recently changed brands of fuel? Oil Pressure Light
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 as designed. 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 warmed 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. 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
STmT. 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.
2-71

Downloaded from www.Manualslib.com manuals search engine 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.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Fuel Gage
GAL '2 I
PREMIUM UNLEADED
FUEL ONLY
The fuel gage shows
approximately how much
fuel is in the
tank. It works
only when the ignition is
in
the RUN position.
If the fuel level
is within approximately two gallons
(7.6 L) of being full, the letter F is shown. If the fuel
level
is between one and two gallons (3.8 and 7.6 L)
from being empty, the letter E is shown. If the fuel
supply gets down
to approximately one gallon
(3.8 L), the E will flash and the FUEL LEVEL VERY
LOW message will appear in the DIC.
