PASS-hti
Your vehicle is equipped
with the PASS-Key
I1
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
I1 is a passive
theft-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS-Key
I1 uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS-Key
II system senses that someone is
using the wrong key, it shuts down the vehicle’s starter an\
d
fuel systems. For about three minutes, the starter won’t work and fuel won’t go to
the engine. If someone tries to
start your vehicle again or uses another key during this
time, the vehicle will not start.
This discourages someone
from randomly trying different keys with different resistor
pellets
in an attempt to make a match. The
ignition key must be clean and dry before it’s
inserted in the ignition or the engine may not start. If
the engine does not start and the SECURITY light is
on or
you get the CLEAN KEY...WAIT 3 MINUTES
message on the DIC, the key may be dirty or wet. Turn
the ignition off.
Clean and dry the key. Wait about three minutes and try
again. The SECURITY light may remain on during this
time. If the starter still won’t work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuses
(see “Fuses and Circuit Breakers” in the
Index). If the starter won’t work with the other key, your
vehicle needs service.
If your vehicle does start, the first
ignition key may be faulty.
See your Aurora retailer or a
locksmith who can service the PASS-Key
11.

I NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor.
2. If it doesn’t start right away, hold your key in
START for about three seconds at a time until your
engine starts. Wait about
15 seconds between each
try to help avoid draining your battery.
3. If your engine still won’t start (or starts but then
stops),
it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again,
do the same thing.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your retailer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual
that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.

If the coolant temperature is over 261 OF ( 127 O C), the
message HOT
... STOP ENGINE will appear. 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.
In “Problems on the Road,” this manual shows what to
do, See “Engine Overheating” in the Index.
If your coolant level is low, the message LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level as soon as possible.
See “Engine Coolant” in the Index.
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 (&-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, which
may prevent more serious damage
to your vehicle. This
system is also designed
to assist your service technician
in correctly diagnosing any malfunction.
ProCarManuals.com

The following may prevent more serious damage to
your vehicle: I 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
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.
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
If 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. Put your vehicle in PARK (P). 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.
ProCarManuals.com

If the Light Is On Steady
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. 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 this condition, 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.
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.
Sometimes when the engine is idling at a stop, me
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.
Don't keep driving if the oil pressure is low. ir
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.

When the remaining oil life or transaxle fluid life is low,
the system will alert you with a message:
CHANGE OIL SOON or
CHANGE TRNS
FLUID SOON
When the oil or transaxle fluid life is down to zero, you
will receive the message:
CHANGE
OIL NOW or
CHANGE TRNS FLUID NOW
To reset the
OIL LIFE reminder after an oil change
or the
TRNS FLUID LIFE reminder after a transaxle
fluid change:
With the ignition on, press the ENG button
so the OIL
LIFE percentage or the TRNS LIFE percentage is
displayed.
Press RESET and hold for five seconds. The word
RESET will appear, then OIL LIFE 100% or TRNS
FLUID 100%.
Remember, you must reset the OIL LIFE or TRNS
FLUID yourself after each oil or transaxle fluid change.
It will not reset itself. Also, be careful not to reset the
OIL LIFE or TRNS FLUID accidentally at any time
other than when the oil or transaxle fluid
has just been changed.
It can’t be reset accurately until the next oil or
transaxle fluid change.
The Driver Information Center does not replace the need
to maintain your vehicle as recommended in the
Maintenance Schedule in this manual. Also, the oil
change reminder will not detect dusty conditions or
engine malfunctions that may affect the oil.
If you drive
in dusty areas, change your oil after every
3,000 miles
(5 000 km) or three months, whichever occurs first,
unless the DIC instructs you to do
so sooner. Also, the
oil change reminder does not measure how much oil you
have in your engine.
So, be sure to check your oil level
often. See “Engine Oil” in the Index.
Check Oil Level Warning
When CHECK OIL LEVEL appears, it indicates that the
engine oil level is
1 to 1 1/2 quarts (0.9 L to 1.4 L) low.
The message will appear only if the engine is running
and it’s been at least eight minutes since the engine was
last running. If the message appears, check the oil
dipstick level. If
it reads low, your oil level should be
brought up to the proper level (see “Engine Oil” in the
Index). After bringing the oil to the proper level, the
ignition must be off for eight minutes to allow the
majority of oil to drain into the oil pan.

Understanding Radio Reception
FM Stereo
F'M stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations
to interfere with each other. AM can pick
up'noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful
to your hearing. Take precautions by
adjusting the volume control
on your radio to a safe
sound level before your hearing adapts to it.
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, Delco radio or other
systems, and even damage them. Your vehicle's
systems may interfere with the operation of
sound equipment that
has been added
improperly.
So, before adding sound equipment, check with
your retailer and be sure to check Federal rules
covering mobile radio and telephone units.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged

Avoid needless heavy braking. Some people drive in
spurts -- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is
a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot
of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot
of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If
you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent
a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
LOCK
ANT‘- (e)
If there’s a problem with the
anti-lock brake system, this warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out.
Of course,
you’ll find experienced and able service experts in
Aurora retailers all across North America. They’ll be
ready and willing to help if you need it. Here are some
things you can check before a trip:
