Rear Door Security Lock
Your Buick is equipped with rear door security locks
that help prevent passengers from opening the rear doors
of your car from the inside.
To use one of these locks:
1. Move the lever on the door all the way up to the

ENGAGED position.
3. Do the same thing to the other rear door lock. The
rear doors of your vehicle cannot be opened from
inside when this feature is
in use. If you want to open a
rear door when the security lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If
you don’t cancel the security lock feature, adults or
older children who ride
in the rear won’t be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work, and
how to cancel the locks.

To cancel the rear door lock: Theft
1. Unlock the door from the inside and open the door

The rear door locks will now work normally. Vehicle theft
is big business, especially in
some cities.
Although your Buick has
a number of theft deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways
you can
help.
Kev in the ignition: If you walk away from your
vehicle with the keys inside, it’s an
easy target for joy
riders or professional thieves
-- so don’t do it.
When
you park your Buick and open the driver’s door,
you’ll hear a tone reminding
you to remove your key
from the ignition and take it with
you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transaxle. And remember
to lock the doors.
Parking at Night: Park in a lighted spot, close all
windows and lock your vehicle. Remember to keep your
valuables out
of sight. Put them in a storage area, or take
them with you.
Parking Lots:
If you park in a lot where someone will
be watching your vehicle, it’s best
to lock it up and take
your keys. But what if you have to leave your ignition
key? What if you have
to leave something valuable in
your vehicle?

PASS-Key I1 TM
Your vehicle is equipped with the PASS-Key I1 TM
(Personalized Automotive Security System) theft
deterrent system. PASS-Key I1
TM 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 uses a resistor pellet in the ignition key
that matches
a decoder in your vehicle.
When the PASS-Key I1
TM 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 start and the “SECURITY” light comes
on, 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 will 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 the other
ignition key. At this time, you may also want to check
the
fuse (see “Fuses and Circuit Breakers” in the Index).
If the starter won’t work with the other key, your vehicle
67

needs service. If your vehicle does start, the first ignition
key may be faulty. See
your Buick dealer or a locksmith
who can service the PASS-Key
I1 .
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work and the
security light will flash. But
you don’t have to wait three
minutes before trying one
of the other ignition keys.
See your Buick dealer or a locksmith who can service
the Pass-Key
I1 TM to have a new key made.
If you’re ever driving and
the “SECURITY” light comes
on and stays on,
you will be able to restart your engine if
you
turn it off. Your PASS-Key I1 system, however, is
not working properly and must be serviced by your
Buick dealer. Your vehicle is not protected by the
PASS-Key I1 system.
If you lose or damage a PASS-Key I1 TM ignition key, see
your Buick dealer or
a locksmith who can service
PASS-Key I1
TM to have a new key made.

Care of Your Cassette Tape Player
Your tapes will sound best if you clean your cassette
tape player from time to time. Use a non-abrasive
cleaning cassette instead of a music tape. Follow the
instructions on the cleaning cassette.
Store cassette tapes away from extreme heat or direct
sunlight. Protect the open ends from dirt or damage;
store them in their original cases or other protective
cases. Cassettes eventually wear out and you may need
to replace them
if they become noisy.
