service Oldsmobile Aurora 1997 s User Guide

Your vehicle may also have a driver information system
that works along with the warning lights and gages. See
“Driver Information Center” in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about
70 seconds. If the
driver’s belt is already
buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you
if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules, the wiring and the crash
sensing and diagnostic module.
For more information on the air bag system, see
“Air
Bag” in the Index.
AIR BAG
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays
on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn
the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.

If the light and chime come 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 “Towing
Your Vehicle” in the Index.)
‘A CAUTI
I
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake 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.
Parking Brake Indicator Light
PARK
When the ignition is on, this
light will come on when
you set your parking brake.
The light will stay on
if
your parking brake doesn’t
release fully.
If you try to
drive off with the parking
brake set, a chime will also
come on until you release
the parking brake.
This light should also come on when you turn the
ignition key to START.
If it doesn’t come on then, have
it fixed
so it will be ready to remind you if the parking
brake hasn’t released fully.

ANT‘- (e)
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.
That’s normal.
Traction Control System Warning Light
TRACTION
OFF
This warning light should
come on briefly as you start
the engine. If the warning
light doesn’t come on then,
have it fixed

if there’s
a problem.
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 Aurora 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 “Brake System
Warning Light” earlier
in this section.
The anti-lock brake system warning light should

on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.
If it stays on, or comes on 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:
0
0
0 If you turn the system off by pressing the
TRACTION
CONTROL button located on the
center console, the warning light will come on
and
stay on. To turn the system back on, press the button
again. The warning light should
go off. (See
“Traction Control System” in the Index for
more information.)
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
your brakes begin
to overheat, the traction control
system will turn
off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn
off and
the warning light will come
on.

Malfunction Indicator Lamp
(Service Engine
Soon Light)
SERVICE
ENGINE SOON
Your Aurora is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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.
(In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) 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:
a
0
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 is 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 If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
0 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.
You may be able to correct the emission system
malfunction by considering the following:
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.
2-76

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
OIL
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. 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.
2-77

The oil light could also come on in three other situations:
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.
0 Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.
If you make a hard stop, the light may come on for a
moment. This is normal.
d!!, 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.
2-78

Fuel Gage
When the ignition is on,
your
fuel gage tells you
about how much fuel you
have left.
When you have less than
3.0 gallons (1 It .3 L) of fuel
remaining, the message LOW FUEL will be displayed
and a chime will sound. You need to get more
fuel
right away.
Press the FUEL button on the Driver Information Center
to turn off the warning. Here
are four things that some owners ask about. None
of these show a problem with your fuel gage:
0
0
0
0
At the service station, the gas pump shuts off before
the gage reads
“F’ (Full).
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The tank is not necessarily empty when the pointer is
over the
“E” (Empty) mark. There is a reserve of
about 1.5 gallons (5.6 L) in the tank. You should still
get more fuel as soon as possible.

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 Aurora 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.
