light CADILLAC CATERA 2001 1.G Service Manual

2-79
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, 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 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.
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.

2-80
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.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.

2-81
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
CHECK ENGINE 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.
Oil Pressure Light/Gage
The light and gage tell you if there could be a problem
with the engine oil pressure.
United States Canada
The gage shows the engine oil pressure in pounds
per square inch (psi). Canadian vehicles show
pressure in kilopascals (kPa).

2-82
The oil light goes on when
you turn the key to ON or
START. It goes off once
you start the 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 the engine properly. You could
be low on oil and you might have some other
system problem.
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.
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.

2-83 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.
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.

2-84 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 full.

The gage may change when you turn, stop or
speed up.
Low Fuel Light
If the fuel level is low,
approximately one (3.8L) 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.

2-85
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.
Automatic Transmission Warning Light
(If Equipped)
This light comes on briefly
when the ignition is turned
on. If the light remains on
or lights up while driving,
there may be a fault in the
automatic transmission.
Have your vehicle serviced.
Leveling Indicator Light
This light comes on steady
when the rear load level in
your vehicle changes.Do not drive your vehicle when this light is on.
The rear of your vehicle is too low and part of the
body or the rear axle may be damaged when driving
over bumpy roads. When the light goes out, leveling
is complete. This procedure is automatic
-- you don't
have to do anything.
If the light comes on flashing, there may be a problem
with the leveling system. You should reduce your
vehicle speed and have your vehicle serviced soon.
Brake Pad Wear Indicator Light
This light comes on when
the brake pads on your
vehicle have significantly
worn. The pads will have to
be replaced, so have your
vehicle serviced soon.
