light Oldsmobile Intrigue 2002 s Service Manual

2-79
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.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 or 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.

2-80 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.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.

2-81 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.
Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition is
turned to ON, the LOW
OIL 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.

2-82 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, see ªHow to Reset the Change Oil Lightº
in the Index.
Security Light
This light will come on
when you turn the key to
START and will stay on
until the engine starts.
If you're driving and the SECURITY light comes on
and stays on, your Passlock

system is not working
properly. Your vehicle is not protected by Passlock and
you should see your dealer. For more information, see
ªPasslockº in the Index.
Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.

2-83 Low Washer Fluid Light
This light appears when
your vehicle is low on
windshield washer fluid.
This light will come on when your ignition is turned on
to check the bulb. It will go out after a few seconds. If
the light does not come on when you start your vehicle,
the bulb may need to be replaced. See your dealer to
have it fixed right away.
If this light appears while you're driving, your vehicle is
low on washer fluid. Be sure to refill the tank as soon as
possible so that you'll have washer fluid available when
you need it.
Fuel Gage
United States Canada
Your fuel gage tells you about how much fuel you have
left when the ignition is on.
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.

2-84
Here are four things that some owners ask about. All
these things are normal and do not indicate a problem
with the fuel gage:

At the gas station, the gas pump shuts off before the
gage reads full.

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
takes more (or less) than half the fuel tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.Low Fuel Warning Light
United States Canada
If your vehicle is low on fuel, this warning light near the
fuel gage will come on.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working.
If it doesn't come on then, the bulb may need to be
replaced. See your dealer to have it fixed right away.

3-3
Mode Buttons
Each button has an indicator which will glow when the
button is pressed.
(Vent): This setting directs air through the
instrument panel outlets.
(Bi-Level): This setting directs air two ways. Half
of the air is directed through the instrument vent outlets.
Most of the remaining air is directed through the floor
ducts and a little to the defrost and side window vents.
(Floor): This setting sends most of the air
through the ducts near the floor. The rest comes out
of the defroster and side window vents. When using
this setting in the recirculation mode, the windows
may fog up. See ªRecirculationº in the Index for
more information.
(Defogger): This setting allows half of the air to go
to the floor ducts and half to the defrost and side
window vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 38F (3.3C). Even when the
compressor is running, you can control the temperature.
(Defroster): This setting directs most of the
air through the defrost and side window vents. Some
of the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 38F (3.3C). Even
when the compressor is running, you can control
the temperature.
A/C (Air Conditioning): Press this button to
operate the air conditioning compressor. An indicator
light in the button will flash briefly and then stay on to
let you know that the air conditioning is on. If the light
in the A/C button turns off after the flashing has
stopped, the air conditioning is not on. The air
conditioning will not come on for two reasons:

The outside temperature is below 38F (3.3)C).

The refrigerant pressure is too low or too high. See
ªAir Conditioning Refrigerantsº in the Index.

3-4
(Recirculation): This button is used to recirculate
much of the air inside your vehicle. This setting is not
available in defogger or defroster. Operating the system
in recirculation may cause the windows to fog up when
the weather is cold and damp. To clear the fog, use the
defog or defrost modes and increase the fan speed. To
avoid refogging of the windows, use the outside air
mode.
(Outside Air): This button is used to bring
outside air into the vehicle.
Air Conditioning
On very hot days, open the windows long enough
to let hot inside air escape. This reduces the time
the compressor has to run, which should help with
fuel economy.
For quick cool
-down on very hot days, use the
vent outlets, recirculation with the temperature knob
turned all the way to the blue area, the air conditioner
on, and the fan on a high setting. If this setting is used
for long periods of time, the air in your vehicle may
become too dry.For normal cooling on hot days, use the vent outlets
with the temperature knob turned to the blue area. With
the A/C button and the outside air button pressed in, the
system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use bi
-level with the temperature
knob in the middle with the A/C button and the outside
air button pressed. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice the
temperature difference more at some times than others.
Heating
On cold days turn the fan on and use floor and the
outside air button pressed in with the temperature knob
turned all the way to the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-8
Auto Button
For the most efficient operation of the system, press the
AUTO button and set the temperature. The system will
select the best fan speed and airflow settings to keep you
comfortable. The air conditioning compressor will run if
the outside temperature is above 38
F (3.3
C). You
may notice a delay of three to four minutes before the
fan comes on. For the automatic system to function,
the temperature must be set between 61
F (16
C)
and 89
F (31
C).
If the temperature setting of 61
F (16
C) is chosen, the
system will remain at the maximum cooling setting and
fan speed. If the temperature is set at 89
F (31
C), the
system will remain at the maximum heat setting and fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.ECON (Economy Air Conditioning): Press the ECON
button to turn the compressor on and off. The indicator
light is illuminated when the compress is off. AUTO
will not be illuminated, but the system will maintain
automatic air delivery and fan speed control. The system
will attempt to control the temperature without the help
of the compressor.
Off: Press the OFF button to turn the system off. The
display will show OFF and the outside temperature.
Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time the air
conditioning compressor has to run, which should help
fuel economy.
For quick cool
-down on very hot days, use the vent
outlets and recirculation, along with the air conditioning.
If this setting is used for long periods of time, the air in
your vehicle may become too dry.

3-9
For normal cooling on hot days, use the vent outlets and
outside air with the air conditioning. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
To remedy this, you can use bi
-level with the air
conditioning on. The system will bring in outside air and
direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Heating
On cold days use the floor mode and the temperature
turned toward red, with a high fan setting. The system
will bring in outside air, heat it and send it to the
floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine
coolant heater warms the coolant your engine and
heating system use to provide heat. See ªEngine
Coolant Heaterº in the Index.Ventilation
For mild outside temperatures when little heating or
cooling is needed, use the vent outlets, a fan setting,
ECON and outside air to direct outside air through your
vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use the defrost button. To warm passengers while
keeping the windows clean, select defog by pressing
the MODE button.
