light Oldsmobile Aurora 1998 s Service Manual

Malfunction Indicator Lamp
(Service Engine Soon Light)
0
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
SERVICE
ENGINE SOON
This system is called OBD I1 (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.
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. Retailer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Retailer 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 “If
the Light Is On Steady” 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 “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
retailer 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. 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.
It
will take a few driving trips to turn the light off.
2-72

Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” 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 retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
Oil Pressure Warning Light
If you have a problem with
your oil, this light may
stay on after you start your
engine, or come on when
OIL you are driving.
A warning chime and the message
LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The oil light could also come on briefly when the
ignition is on but
the engine is not running. The light
will come on as a test to show
you it is working, but the
light will go out when you turn the ignition to START.
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.

Comfort Controls
This section tells you how to operate your climate
control system. Your climate control system uses
ozone-friendly
R- 134a refrigerant.
Automatic Electronic Climate Control
Your vehicle is equipped with a Dual Zone Automatic
Electronic Climate Control System. You can use the
automatic setting or override the automatic setting
by
using the manual controls. Your vehicle also has the
flow-through ventilation system described later in
this section. If
the display ever starts flashing after the automatic
electronic climate control system
is started, there is a
problem with the electronic climate control system and
you should see your dealer for service.
AUTO-PUSH Knob
By pressing the AUTO-PUSH knob, you have selected
the electronic climate control system to be in the
automatic mode. The climate control system will
automatically control the air temperature, air distribution
and the fan speed based
on the temperature inside the
vehicle, the outside temperature and the sun load.

Automatic Operation
Press the AUTO-PUSH knob when you want the system
to automatically adjust the interior temperature to your
preference. When the system
is set for automatic
operation, air will come from the floor, upper or the
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and the
sun load.
Fan speed will vary as the system reaches and maintains
the comfort setting you have selected.
To find your comfort setting, start with the system in
automatic mode by pressing the AUTO-PUSH knob.
Adjust the comfort setting by using the red and blue
buttons located below the digital display until
you reach
a setting of
75°F (24"C), on the display. Give the
vehicle about 20 minutes to stabilize and then readjust
the comfort setting
if necessary. The display will show
the comfort setting for five seconds and then it will
show the outside temperature.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends
on the engine coolant temperature and the
outside temperature. Rotating the AUTO
FAN knob will
override this delay by turning off the automatic fan
mode and changing the fan speed.
...................................... ...................................................
Your automatic electronic climate control system has
two sun sensors located on the top of the instrument
panel that detect direct sunlight.
To keep you and your
passengers comfortable, the system may supply cooler
air to the side toward the sun. Be careful not to put
anything over these sun sensors. The automatic
electronic climate control system may not operate
correctly
if these sensors are covered.
To change the automatic electronic climate control
display from an English display to a Metric display,
push the
OFF button located in the Driver Information
Center (DIC) for two seconds. The display in the DIC
will also change from an English to a Metric display. To
return to an English display, repeat the above procedure.

Operating the RECIRC mode in cold temperatures or
under high humidity conditions may cause moisture to
form on the inside of the windshield.
If this condition
occurs, deselect the RECIRC button.
A/C ON: Press this button to turn the air conditioning
on and
off. If the system is operating in the automatic
mode, the A/C
ON indicator light will automatically
illuminate. In the auto mode, the
A/C compressor will
only operate when the system determines it
is needed.
OFF: Rotate the AUTO-PUSH knob to OFF. Turning
the system off will cause the fan to turn off and the
airflow to be directed out the lower floor outlets. The
system will still try to keep the interior
of the vehicle at
the previously chosen
comfort setting. The outside
temperature will show in the display when the system is
set to
OFF.
Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all modes
unless the A/C
ON button is in the off position (the
indicator light will not be illuminated). However, the air
conditioning compressor will not operate when the
outside temperature is below
42°F (7 "C). When the air
conditioner is on, you may sometimes notice slight
changes
in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level. If the
system is in the automatic mode (AUTO-PUSH knob
indicator light is on), during very hot days the system
will automatically
go to the RECIRC mode and the
temperature door will be positioned at
the full cold
position for maximum cooling.
You can choose the
extreme comfort setting of
60" F (1 6 O C), but the
system will not cool any faster by choosing the extreme
comfort setting.

Heating
In cold weather, if the automatic mode is selected
(AUTO-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of
90°F (32°C) but the system will not
warm
up any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature
of the engine coolant increases. Rotating the
AUTO FAN
knob will override this delay by turning off
the automatic fan control mode and changing the
fan speed.
Ventilation System
Your vehicle’s flow-through ventilation system always
allows outside air
to flow through your vehicle when it
is moving, even when the system is off.
The direction of the air can be controlled by adjusting or
closing the outlets
in the instrument panel. Rotate the
control between the front outlets upward to open the
outlets and downward to close the outlets. Adjust the
direction of airflow
from side to side with the controls in
each outlet.

Defogging and Defrosting
On cool, humid days use the defog setting to keep the
windows clear while also providing heat through the
lower outlets. Press
DEF to quickly remove fog or ice
from the windshield.
