2000 CADILLAC CATERA ignition

2-69 Brake System Warning 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.
United States Canada
This light should come on briefly when you turn the
ignition key to ON. 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 Cateraº 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.

2-70 Anti-Lock Brake System Warning Light
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 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 ON. 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
The warning light will flash
when the system senses a
traction change.
If it stays on, or comes on and stays on steady 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.

2-71 Engine Coolant Temperature Warning Light
This light tells you that
the engine has overheated.
If this light comes on, you
should stop the 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 the engine. See ªEngine Overheatingº in
the Index.
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!This reading means the same thing as the warning
light
-- the engine coolant has overheated. You should
stop the car and turn the engine off as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This warning light should
come on for a few seconds
while you are starting the
engine. If the light doesn't
come on, have it repaired.
Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle's coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level
and add coolant as needed. The light should turn off as
soon as the coolant level is at its proper operating range.

2-72 Malfunction Indicator Lamp
(Check Engine 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 CHECK ENGINE 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, transmission,
exhaust 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 CHECK ENGINE 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.

2-73
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.

2-76
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Check Oil Light
This light will come on for
a few seconds when the
ignition is turned on. If the
light doesn't come on, have
it repaired.
If the light comes on while starting and stays on for about
one minute or comes on while driving, the engine oil level
should be checked. Prior to checking the oil level, be sure
your vehicle has been shut off for several minutes and is
on a level surface. Check the oil level and bring it to the
proper level. See ªEngine Oilº in the Index.
Brake To Shift Light
This light will come on to
remind you that you must
press the brake pedal to
shift out of PARK (P).
Cruise Control Light
This light comes on
whenever you set your
vehicle's cruise control.

2-77 Low Washer Fluid Warning Light
This light will come on
when you turn on the
ignition and the windshield
washer fluid container is
less than one
-third full.
Trunk Ajar Light
This light will come on if
your vehicle's trunk is not
completely closed.
Fuel Gage
United States Canada
The fuel gage shows approximately how much fuel is in
the tank. It works only when the ignition is in ON.
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 F.

The gage may change when you turn, stop or
speed up.

2-78 Low Fuel Light
If the fuel level is low,
approximately one (3.8 L)
to two gallons (7.57 L) of
fuel remaining in the fuel
tank, a light will come on
until you add fuel.
The light may begin to flash as the fuel level gets lower.
It will also come on for a few seconds when you first
turn on the ignition as a check to show it's working.
If it doesn't come on then, have it fixed.
Fuel Cap Indicator Light
This light will come on
if the fuel cap has not
been fully tightened, is
missing or has been
improperly installed.
You should recheck your fuel cap to make sure it
is on tight.
If you continue to drive with a loose fuel cap, the
diagnostic system in your vehicle 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. If this happens, the CHECK
ENGINE light may come on. For more information, see
ªMalfunction Indicator Lampº earlier in this section.
