service Oldsmobile Aurora 1998 s User Guide

START (E): This position starts your engine. When the
engine starts, release the key. The ignition switch will
return to
RUN for normal driving.
FNOTICE:
If your key seems stuck in LOCK and you can’t
turn
it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using
a tool to force it could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.
Key Reminder Warning
If you leave your key in the ignition, with the engine off,
you will hear a warning chime when you open the
driver’s door.
Retained Accessory Power
After you turn the ignition off and remove the key, you
will still have electrical power to such accessories
as the
radio, power windows, and sunroof (if equipped) for up
to
10 minutes. But if you open a door, power is shut off.
Always leave your key in
LOCK. If you leave your key
in any other position than
LOCK, you battery will
discharge prematurely.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL
(N) only.
NOTICE:
~ ~ ~~
Don’t try to shift to PARK (P) if your Aurora is I
moving. If you do, you could damage the
transaxle. Shift to PARK
(P) only when your
vehicle is stopped.

Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK
(P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.”
To
prevent torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the driver’s
seat.
To find out how, see “Shifting Into PARK (P)” in
the Index.
When you are ready to drive, move the shift lever out
of PARK
(P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transaxle,
so you
can pull the shift lever out
of PARK (P).
Shifting Out of PARK (P)
Your vehicle has a brake-transaxle shift interlock. You
have to fully
apply your regular brake before you can
shift from PARK (P) when the ignition
is in RUN. See
“Shifting the Automatic Transaxle” in the Index.
If you cannot shift out of PARK
(P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK
(P) as you maintain brake application. Then
move the shift lever into the gear you wish. Press the
shift lever button before moving the shift lever.
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the ignition key to OFF. Open and close the
driver’s door
to turn off the retained accessory
power feature.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Take your vehicle to an authorized service center
as soon as you can.

Programming the Transmitter
Do not use the universal transmitter with any garage
door opener that does not have the “stop and reverse”
safety feature. This includes any garage door opener
model manufactured before April
1, 1982.
rse sure that people and objects are clear of the garage
door you are programming. Your
vehicle’s engine should be turned off while
programming your transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a universal
transmitter channel, proceed to Step
2. Otherwise,
hold down the two outside buttons on the universal
transmitter until the red light begins to flash rapidly
(approximately
20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.
2. Hold the end of your hand-held transmitter against
the bottom surface of the universal transmitter
so
that you can still see the red light.
3. Decide which one of the three channels you want to
program. Using both hands, press the hand-held
transmitter button and the desired button on the
universal transmitter. Continue to hold both buttons
through Step
4.
4. Hold down both buttons until you see the red light
on the universal transmitter flash slowly then
rapidly. The rapid flashing, which could take up
to
90 seconds, indicates that the universal transmitter
has been programmed. Release both buttons
three seconds after the light starts to flash rapidly.

When one of the warning lights comes on and stays on
when you are driving, or when one
of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle may also have a driver information system
that works along with the warning lights and gages. See
“Driver Information System” 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.)
Your brake system may not be working properly
if the brake warning light
is on. Driving with 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 vehicle 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 come
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
the warning light doesn’t corne on then, have it fixed

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.
