2001 CADILLAC ELDORADO warning light

2-68
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds 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.
Charging System Indicator Light
When you turn the ignition
key to RUN, this light will
come on briefly to show
that the generator and
battery charging systems
are working.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories.
Brake System Warning and Park Brake
Indicator Light
Your vehicle'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
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.

2-69
This light should come on
briefly when you turn the
ignition key to RUN. If it
doesn't come on then,
have 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 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.

2-70
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.
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

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.

and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature
Warning Light
This light tells you that the
engine has overheated. You
should stop your vehicle
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. See ªEngine Overheatingº
in the Index.

2-71 Engine Coolant Temperature Gage
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. See ªEngine
Overheatingº in the Index.
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.

If this message appears and stays on while driving or
after starting your vehicle, have it checked immediately
to determine the cause of this problem. To help the
generator recharge the battery quickly, you can reduce
the load on the electrical system by turning off the
accessories. You can monitor battery voltage on the
DIC by pressing the INFO (SKIP) button. The normal
range is 11.5 to 15.5 volts.
CHANGE ENGINE OIL
- 82: This means that the
life of the engine oil has expired and it should be
changed within 200 miles (322 km). See ªEngine Oilº

- 36: For correct operation of
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 ªEngine
Oilº in the Index.

4-7
Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
Here's how anti-lock works. Let's say the road is wet.
You're driving safely. Suddenly an animal jumps out in
front of you.
