2000 Oldsmobile Intrigue engine

2-60 Precision Control System (PCS) Warning
Light (Option)
This light should come on
briefly as you start your
engine. If the light doesn't
come on then, have it
serviced so it will be ready
to warn you if there's
a problem.
If the PCS warning light comes on, it means there may
be a problem with your Precision Control System. When
this light comes on, so will the TRAC OFF light and
both the Precision Control System and the Traction
Control System will not be functioning. If these lights
come on, try to reset the system (stop; turn off the
engine; then start the engine again). If the PCS and
TRAC OFF lights remain on, it means there is a
problem and you should see your dealer for service.
Reduce your speed and drive accordingly.
Low Traction Active (LOW TRAC) Light
Your LOW TRAC
(Low Traction Active) light
may come on for one of the
following reasons:

The Precision Control System (PCS) (if equipped) is
active and is adjusting brake pressure to help your
vehicle continue to go in the direction in which you
are steering. The PCS activates when the computer
senses that your vehicle is starting to spin, as might
happen if you hit a patch of ice or other slippery
surface on the road, and assists the driver by
selectively applying any one of the vehicle's brakes.
The system is designed to help you in bad weather or
other difficult driving situations by making the most
of whatever road conditions will allow. When the
system is on, you may hear a noise or feel a vibration
in the brake pedal. This is normal.

2-61

The optional Traction Control System is active and is
limiting wheel spin. You may feel the system
working, but this is normal. Slippery road conditions
may exist, so adjust your driving accordingly.
If the LOW TRAC light comes on, slippery road
conditions may exist, so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
moves into the red area,
your engine is too hot.That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on, your
system is low on coolant,
and the engine
may overheat.
This light will come on briefly when the ignition is
turned to ON. This is normal.
See ªEngine Coolantº in the Index for more
information, and have your vehicle serviced as
soon as possible.

2-62 Malfunction Indicator Lamp
(Service Engine Soon Light)
United States Canada
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 and a chime will sound 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.

2-63
NOTICE:
Modifications made to the engine, transaxle,
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 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.
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.

2-64
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.

2-65
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.
Oil Warning Light
If you have a problem with
your oil, this light may stay
on after you start your
engine or come on when
you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have your vehicle serviced immediately.
The oil light could also come on when the ignition is on
but the engine is not running. This is normal. The light
comes on as a test to show you it's working, but the light
should go out when you turn the ignition to ON. If it
doesn't come on with the ignition on, you may have a
problem with the fuse or bulb. Have it fixed right away.

2-66
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.
Service Vehicle Soon Light
This light will come on
briefly when the ignition is
turned to ON to show that
the bulb is working.
This light indicates problems with your vehicle that are
not related to emissions.
These problems may not be obvious and may affect
vehicle performance and durability. Consult your dealer
for necessary repairs to maintain vehicle performance.

2-67 Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition is
turned to ON, the LOW
OIL LEVEL light will
briefly come on.
If the light does not flash, have it fixed so it will be
ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index.)
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for an
extended period of time, allowing the oil normally in
circulation to drain back into the oil pan.
Change Oil Light
The CHANGE OIL light
should come on briefly as a
bulb check when you start
the engine. If the light
doesn't come on, have the
vehicle serviced right away.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
For additional information see ªEngine Oil, When to
Changeº in the Index. To reset the GM Oil Life
System,
