Your Cadillac’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other
part can
still work and stop you. For good braking though, you
ueed both parts working well.
If the warning light comes
on, there could be a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come on
briefly when you turn the
’ ignition key to RUN. If it
doesn’t come
on then, have
1 it fixed so it will be ready to
warn
you if there’s a
problem.
If the light comes on while you
are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed
for service. (See “Towing Your Vehicle”
in the Index.)

Your brake system may not be working properly
if the brake system warning light
is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.

When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on
if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.

With the anti-lock brake system, the light(s) will come
on when you start your engine and may stay on for
several seconds. That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon as
possible and turn the ignition
off. Then start the engine
again to reset the system.
If the light still stays on, or
comes on again while you’re driving, your Cadillac
needs service. If the regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti-lock brakes.

Warning
Light
This light tells you that your
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.
Engine Coolant Temperature Gage
Analog Cluster
This gage shows the
engine coolant
temperature.
If the gage
pointer moves into the red
area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant has overheated. The section
“Problems on the Road” in this manual explains what to
do. See “Engine Overheating” in the Index.

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 and a chime will sound 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.
I 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.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 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 vehicle. 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 “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 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.
CAI JTTON:
Don’t keep driving if the oil ssure 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.
hOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

PREMIUM UNLEADED FUEL
ONLY
Digital Cluster
I
Analog Cluster
The fuel gage shows approximately how much fuel is
in the tank. It works only when the ignition is in the
RUN position.
On
the digital cluster, 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
three gallons
(3.8 and 11.4 L) from being empty, the letter
E is shown. If the fuel supply gets down to
approximately three gallons
(1 1.4 L), the E will display
and the FUEL LEVEL LOW message will appear on
the
DIC. (On the analog fuel gage, the FUEL LEVEL LOW
message will also appear.) When the fuel supply gets
down to about
1.2 gallons (4.5 L) from being empty,
the letter
E begins to flash indicating that fuel is
needed soon.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything
is wrong with the fuel gage.
0 At the gas station the gas pump shuts off before the
gage reads
F.
0 It takes more (or less) gas to fill the tank than the
gage said. For example, the gage read
8 GALLONS,
but it took more (or less) than the tank’s remaining
capacity to fill it.
0 The gage may change when you turn, stop or
speed up.

Digital Cluster
For vehicles equipped with an analog cluster (not shown), fuel data can be obtained by pressing the
INFO button. See “Analog Control Buttons” later in
this section.
The fuel data panel tells you all
you need to know about
the fuel economy and how far you can travel with the
fuel remaining. Press the
AVG button to display the average
mile-per-gallon (AVG MPG). You can also display it in
metric units by pressing the ENG MET button.
When AVG MPG is selected, the total distance is
divided by the total
fuel used.
When the INST button (Instantaneous Fuel Economy) is selected,
you will see what the fuel economy is at that
instant. The computer takes a new reading twice every
second. It will show economy up to
70 miles-per-gallon
(or
2 L per 100 km).
To reset the average fuel economy, press the
INFORMATION button until the AVG
MPG is
displayed on the DIC. Press and hold the RESET button until both the fuel data center and
DIC display reads 0.0.
The RANGE display shows how far the computer thinks
you can travel with the fuel that is in the tank. The
computer does
not know what driving conditions will be
like for the rest of your trip,
so the range is estimated
based
on the recent fuel economy. Therefore, the range
reading may change as your driving habits change.
Going from city to highway driving may increase the
range reading.
If the range display shows LO, you should stop for fuel
as soon as possible. Your computer needs enough data
for the RANGE reading to work.
