The safety belt locks if there’s a sudden stop or a crash.\

It’s possible that an automatic belt could keep you from
fully opening a door. That can happen if the door was
slammed shut very hard. Just close the door all the way,
then slowly open it. If that doesn’t
fix it, then your
Buick needs service.
We hope you’ll always keep your automatic belt
buckled. However, you may need to unbuckle it in an
emergency.
And you would need to unbuckle it to let
someone get into the center front seat position, if ,your
vehicle has one.
r
The lap belt should be worn as low on the hips as
possible. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the
lap belt.
If you slid under it, the belt would apply force
at
your abdomen. This could cause serious or even fatal
injuries. The shoulder belt should
go over the shoulder
and across the chest. These parts of the body are best
able to take belt restraining forces.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR
BAG. The system checks for
electrical malfunctions, and the light tells you
if there is
a problem.
AIR BAG
You will see this light flash
for a few seconds when
you
turn your ignition to “Run”
or “Start.” Then the light
should go out, which means
the system is ready.
Remember,
if the air bag readiness light doesn’t come
on when you start your vehicle, or stays on, or comes on
when you are driving, your air bag system may not work
properly. Have your vehicle serviced right away.
How The Air Bag System Works
Where is the air bag?
The driver’s air bag is in the middle of the steering
wheel.

What will you see after an air bag inflation?
After the air bag has inflated, it will then quickly
deflate. This occurs
so quickly that some people may
not
even realize that the air bag inflated. Some
components
of the air bag module in the steering wheel
hub may be hot for a short time, but the portion of the
bag that comes into contact
with you will not be hot to
the touch. There will be small amounts of smoke and
dust coming from vents
in the deflated air bag. The air
bag will
not impede the driver’s vision or ability to steer
the vehicle, nor will
it hinder the occupants from exiting
the vehicle.

The air bag is designed to inflate only once. After it
inflates, you’ll need some new parts for your air bag
system.
If you don’t get them, the air bag system
won’t be there to help protect you
in another crash.
A new system will include the air bag module and
possibly other parts. The service manual has information about
the need to replace other parts.
Your vehicle is equipped
with a diagnostic module,
which records information about the air bag system
if the air bag deploys during a crash: The module
records information about the readiness of the
system, which sensors activated the deployment, and
whether the driver’s safety belt was
in use.
Let only qualified technicians work on your air bag
system. Improper service can mean that your air bag
system won’t work properly. See your dealer for
service.
NOTICE:
If you damage the cover for the driver’s air bag, it
may not work properly. You may have to replace
the air bag on the steering wheel.
Do not open or
break the air bag cover.
Is the smoke from an air bag inflation harmful?
The particles emitted during air bag inflation are not
harmful to most people. Some people
with respiratory
ailments may .experience difficulty breathing
if they stay
in the vehicle with the windows closed after air bag
inflation.
So, if your air bag inflates, you and any
passengers should exit the vehicle
if and when it is safe
to do
so. If you or your passengers can’t get out of the
vehicle,
try to get fresh air by opening a window,
turning on the
fm, or opening a door.

Servicing Your Air Bag-Equipped Buick
The air bag affects how your Buick should be serviced.
There are parts
of the air bag system in several places
around your vehicle. You don’t want the system to
inflate while someone is working on your vehicle. Your
Buick dealer and the
1994 Regal Service Manual have
information about servicing
your vehicle and the air bag
system. The air bag system does not need regular
maintenance.
I A CAUTION:
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely
to be
seriously injured
if they don’t wear safety belts.
A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible
throughout the pregnancy.

PASS-Key@II
Your vehicle is
equipped
with the
PASS-Key@II
(Personalized
Automotive Security
System) theft deterrent
system. PASS-Key(%
is a passive theft
deterrFnt 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% 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, the key may be dirty or wet. Turn
the ignition off.
Clean and dry the key. Wait about three minutes and
try
again. 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 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@II.
If you accidentally use
a key that has a damaged or
missing resistor pellet, the starter won’t work. 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(% to have a new key made.
If you lose or damage a PASS-Key% ignition key, see
your Buick dealer or a locksmith who can service
PASS-Key@II to have a new key made.

E
With the ignition key in the ignition switch, you can turn
the switch to five different positions.
(A) Accessory: This position lets you use things like the
radio and the windshield wipers when the engine is off.
To
use, push in the key and turn it toward you. Your
steering wheel
will remain locked, just as it was before
you inserted the key.
(B) Lock: Before you put the key in, your ignition will
be in the Lock position. This position locks your
ignition, steering wheel and transaxle. It’s an theft
deterrent feature.
(C) Off: This position lets you turn off the engine but
stili
turn the steering wheel. It doesn’t lock the steering
wheel like “Lock.” Use “Off’
if you must have your car
in motion while the engine is off (example, if your car is
being pushed).
(D) Run: This is the position for driving.
(E) Start: This position starts your engine.
I NOTICE:
If your key seems stuck in “Lock” and you can’t
turn’it, be sure
it is 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.
Starting Your Engine
Engines start differently. The 8th digit of your Vehicle
Identification Number (VIN) shows the code letter or
number for your engine. You will find the VIN at the top
left of your instrument panel. (See “Vehicle
Identification Number’’
in the Index.) Follow the proper
steps to start the engine.
