Battery Replacement
Under normal use, the batteries in your key chain
transmitter should last about two years.
You can
tell the batteries are weak if the transmitter
won’t work at the normal range
in any location. If you
have to get close to your vehicle before the transmitter
works, it’s probably time to change the batteries.
To Replace Batteries in the Remote Lock Control
1. Remove the screw from the back cover.
2. Lift the front cover off, bottom half first.
3. Remove and replace the two batteries
(Duracell@ type
DL-2016).
4. Reassemble the transmitter.
5. Check the transmitter operation.
Illuminated Entry System
When you press any button on your Remote Lock
Control, the lamps inside your vehicle will go on. These
lamps will
go off after about 25 seconds, or when you
start your engine.
If a door is left ajar, your interior lamps will turn off
after 10 minutes to save your battery.

PASS-Key@II
Your vehicle is equipped with the PASS-Key@II
(Personalized Automotive Security System) theft
deterrent system. PASS-Key@II is a passive theft
deterrent system. This means
you don’t have to do
anything different to arm or disarm the system.
It works
when you insert
or remove the key from the ignition.
PASS-Key@II uses
a resistor pellet in the ignition key
that matches a decoder
in your vehicle. When
the PASS-Key% system senses that someone is
using the wrong
key, it shuts down the vehicle’s starter
and 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 stat and the SECURITY light is on or
you get
the CLEAN KEY. ..WAIT
3 MINUTES message, the key
may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wdit 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@II.

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 fuel injection system 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.

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 comes 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.

Using Your Radio Properly
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:
1. Adjust the volume control to the lowest setting.
2. 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
(Continued)
I NOTICE: (Continued)
engine, Delco@ radio or other systems, and even
damage them. And, 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 is subject to
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes that are not properly stored
in their plastic cases away from contaminants, direct
sunlight, and extreme heat may not operate properly and
could cause premature failure of the tape player.
Cassettes are subject to wear and the sound quality may
degrade over time. Always verify that the cassette tape is
in
good condition before obtaining service on your tape player.
Your tape player should be cleaned with every
50 hours of
use to provide optimum perfornxmce. Your radio may
display “Cln” to remind you that you have used your tape
player for
50 hours without re-setting the tape clean timer.

Highway Hypnosis
Is there actually such a condition as "highway nypnosis"?
Or is
it just plain fdling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There
is something about an easy stretch of road with
the same scenery, along with the
hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don't let it
happen to you!
If it does, your vehicle can leave the
road
in less tlml u second, and you could crash and be
injured.
What can you do about highway hypnosis? First, be
aware that
it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 If you get sleepy, pull off the road into a rest, service,
or parking area and take
a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
