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 conles 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.

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.

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 oii 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.
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.S and 11.4 L) from being empty, the

Downloaded from www.Manualslib.com manuals search engine letter E is shown. If the fuel supply gets down to
approximately three gallons ( I 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.
@ At the gas station the gas pump shuts off before the
gage
reads E
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 econonly
and how far you can travel with the
fuel remaining.

Downloaded from www.Manualslib.com manuals search engine IC-
Press the AVG button to display the average
mile-per-gallon (AVG MPG). You can also display it in
metric units by pressing the
ENGMET 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 ltm).
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. The
DIC display gives you the
status of many of your
vehicle’s systems. The DIC is also used to display driver
personalization features and warninghtatus messages.
Your vehicle may be equipped with the following
features that can be individually customized for up
to two drivers.
