1995 OLDSMOBILE AURORA check engine light

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.

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.

Engine Oil
If the CHECK 01L LEVEL message or the oil warning
light on the instrument panel comes
on, it means you
need to check your engine oil level right away.
For more
information, see “Check Oil Level Message” or
“Oil
Warning Light” in the Index. You should check your
engine
oil level regularly; this is an added reminder.
It’s a
good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn off the engine and give the
oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.
