Downloaded from www.Manualslib.com manuals search engine This feature prevents the engine from operating at too
many revolutions per minute (rprn). When the engine’s
rpm are critically high, the fuel supply to the engine
is shut
off. When the engine speed slows, the fuel
supply will come on again. This helps prevent damage
to the engine.
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before
it becomes serious enough to cause an
expensive repair
or replacement. Paying attention to
your warning lights and gages could also save
you or
others from injury. Warning
lights come
on when there may be or is a
problem with
one of your vehicle’s functions. As you
will see in
the details on the next few pages. some
warning lights come on briefly when
you start the
engine just
to let you know they‘re working. If’ ~OLI

alarmed when this happens.
Gages can indicate when there
may bc or is ;: prohlcn;
with one of your vehicle‘s functions. Oftcn pgch and
warning lights work together to let you kno~, ~,hw
there‘s a problem with your vehicle.
When one of the warning lights comes
on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you what to do about it Please follow this manual’s
advice. Waiting
to do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle also has a Driver Information Center that
works along with the warning lights and gages. See
“Driver Information Center” later
in this section.

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 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.
0 Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Dealer or qualified service center diagnosis and
service rnay be required. The
following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are 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 velzicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see "lf 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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 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 one or more
of these conditions,
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
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.

soon as possible. If the brake warning light is on, follow
the directions in that part.
CHECK COOLANT LEVEL - 02: This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by a Cadillac technician as
soon
as possible.

the low oil sensing system, your vehicle should be on
a level surface.
A false CHECK OIL LEVEL message
may appear
if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been
off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked
on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure
the engine has been off for five
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See “Engine
Oil” in the Index.

appear
for several seconds indicating that you need
washer solvent.
