engine CADILLAC ELDORADO 2002 10.G Owner's Manual

2-65 Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).
You may wonder what happens if a vehicle has to have
a new odometer installed. The new one may read the
correct mileage. This is because your vehicle's computer
has stored the mileage in memory.
Trip Odometer
This button is located in
the center of the instrument
panel to the right of the
steering wheel and below
the air outlets.By pressing this button, you can tell how far you've
traveled since you last set the trip odometer back
to zero.
For information on resetting this button,
see ªDIC Controls and Displaysº in the Index.
English/Metric Display
Press the SKIP INFO button until ENGLISH/METRIC
RESET displays and then press NO INFO RESET
to select.
Other readings such as temperature, fuel and trip
odometer also go back and forth between English
and metric.
Vehicle Speed Limiter
This feature prevents your vehicle from exceeding
speeds that the tires are not rated for. When this
happens, the engine's fuel supply is shut off. When the
vehicle speed slows, the fuel supply will come on again.

2-66 Tachometer
The tachometer is located in
the instrument panel cluster,
to the left of the speedometer.
NOTICE:
Do not operate the engine with the tachometer in
the shaded area or engine damage may occur.
This gage indicates the engine speed in revolutions
per minute (rpm).Engine Speed Limiter
This feature prevents the engine from operating at too
many revolutions per minute (rpm). When the engine's
rpm is 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.
Warning Lights, Gages and Indicators
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 you are
familiar with this section, you should not be alarmed
when this happens.

2-70
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 ªTowing Your Vehicleº in
the Index.
CAUTION:
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.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when your
engine is started 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 vehicle needs
service. If the regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is
also on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.

2-71 Traction Control System Warning Light
This warning light should
come on briefly when the
engine is started.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may
be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.The traction control system warning light may come on
for the following reasons:

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on.

If the traction control system is affected by an
engine
-related problem, the system will turn off
and the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

2-72 Engine Coolant Temperature Warning Light
This light tells you that
the engine coolant has
overheated. A warning
chime will sound if this
light comes on.
As a check, the light should come on for a few seconds
when you start your vehicle.
If the light comes on and the chime sounds while
you are driving, you should stop your vehicle and
turn the engine off as soon as possible. See ªEngine
Overheatingº in the Index for more information.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the shaded area, the engine
is too hot.
When the pointer is in the shaded area, that means
the same thing as when the engine coolant temperature
warning light comes on and the chime sounds.
See ªEngine Coolant Temperature Warning Lightº
previously in this section and ªEngine Overheatingº
in the Index for more information.

2-73 Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (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. 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. 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.
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

2-74
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 may be 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:

Reducing vehicle speed.

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 ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº 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 recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. See ªFilling Your Tankº in the Index.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
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.

2-75
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. See ªFilling Your Tankº in the Index.
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 ªFuelº 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.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days of
routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.

2-76 Oil Pressure Light
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.
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.

2-80 DIC Messages
These messages will appear if there is a problem sensed
in one of your vehicle's systems. Vehicles that are first
sold in Canada will have a number after each message.
This number helps to identify the message which is
only displayed in English.
Pressing the INFO or NO INFO RESET button(s)
will remove most of the following messages from the
DIC display:
APPLY BRAKE TO SHIFT
- 46: This message
will appear if your vehicle is in PARK (P) for about
15 seconds and the brake is not pressed. On the climate
control panel, press the OFF button (next to the MODE
button) and the down arrow on the PASS TEMP button
for about five seconds. Hold the same two buttons to
display the message again.
BATTERY NOT CHARGING
- 7: This message will
appear if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.BATTERY VOLTAGE HIGH
- 8: This message
shows that the electrical charging system is
overcharging (more than 16 volts). To avoid being
stranded, have the electrical system checked by your
dealership. You can reduce the charging overload by
using the accessories. Turn on the lamps and radio, set
the climate control on AUTO and the fan speed on HI,
and turn the rear window defogger on. You can monitor
battery voltage on the DIC by pressing the SKIP INFO
button. The normal range is 11.5 to 15.5 volts when the
engine is running.
BATTERY VOLTAGE LOW
- 6: This message
will appear when the electrical system is charging
less than 10 volts or if the battery has been drained.
If this message appears immediately after starting,
it is possible that the generator can still recharge the
battery. The battery should recharge and may take a
few hours to do so. Consider using an auxiliary charger
to boost the battery after returning home or to a final
destination. (Be sure to follow the manufacturer's
instructions when using a battery charger.)
