2002 CADILLAC ELDORADO ignition

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.

2-73 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.

2-77 Security Light
This light works with
the PASS
-Key II system.
See ªPASS
-Key IIº in the
Index for more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition is
in RUN.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 full.

It takes more (or less) gas to fill the tank than the
gage said. For example, the gage read half a tank,
but it took more (or less) than the tank's remaining
capacity to fill it.

The gage may change when you turn, stop or
speed up.
Fuel Data Display
Everything you need to know about the fuel
economy and how far you can travel with your
vehicle's remaining fuel is displayed on the Driver
Information Center (DIC). Fuel data can be
obtained by pressing the SKIP INFO button
located on the instrument panel above the audio
system. See ªDIC Controls and Displaysº later
in this section for more information.

When the REMOVE KEY message is displayed, remove
the ignition key. Check the ignition key for damage. If it is damaged, it may need to be replaced. If you see
no damage, clean the pellet contacts with a soft cloth or
napkin before inserting the key back into the ignition.
Have your vehicle serviced if the message still appears.

system serviced by a technician as soon as possible.
If the brake warning light is on, refer to the directions
listed in that part.

2-86
STABILITY ENGAGED - 55: You may see
the STABILITY ENGAGED message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help
your vehicle continue to go in the direction in which
you're steering. This stability enhancement system
activates when the computer senses that your vehicle is
just starting to spin, as it might if you hit a patch of ice
or other slippery spot on the road. When the system is
on, you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY ENGAGED message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY ENGAGED message comes on, you'll
know that something has caused your vehicle to start to
spin, so you should consider slowing down.STARTING DISABLED REMOVE KEY
- 33: This
message will appear when the PASS
-Key
II system
senses that an improper ignition key is being used to try
to start the vehicle. Check the ignition key for damage.
If it is damaged, it may need to be replaced. If you see
no damage, clean the pellet contacts with a soft cloth or
napkin. Remove the ignition key and wait for the DIC
to display WAIT 3 MINUTES. The instrument panel
cluster will then run a timer and change the messages
to WAIT 2 MINUTES, WAIT 1 MINUTE and then
START CAR. When the START CAR message is
displayed, try again to start the engine.
THEFT SYSTEM PROBLEM, CAR MAY NOT
RESTART
- 34: This message means there is a problem
in the PASS
-Key
II system. A fault has been detected
in the system which means that the PASS
-Key
II
system is disabled and is not protecting the vehicle.
The vehicle usually restarts, however, you may want to
take your vehicle to a proper service center before
turning off the engine.
