How The Air Bag System Works When is an air bag expected to inflate?
The air bag is designed to inflate in moderate to severe
frontal or near-frontal crashes. The air bag will only
inflate if the velocity
of the impact is above the designed
threshold level. When impacting straight into a wall that
does not move or deform, the threshold level for most
GM vehicles is between 9 and 14 mph. However, this
velocity threshold depends on the vehicle design and
may be several miles-per-hour faster or slower. In
addition, this threshold velocity will be considerably
higher if the vehicle strikes an object such as a parked
car which will move and deform on impact.
The air bag
is also not designed to inflate
in rollovers, side impacts,
or rear impacts where the inflation would provide
no
occupant protection benefit.
In any particular crash, the determination of whether the
, air bag should have inflated cannot be based solely on
the level of damage on the vehicle(s). Inflation is
Where is the air bag?
The driver's air bag is in the middle of the steering
wheel. determined
by the angle of the impact and the vehicle's
deceleration, of which vehicle damage is
only one
indication. Repair cost
is not a good indicator of
whether an air bag should have deployed.

What makes an air bag inflate?
In a frontal impact of sufficient severity, sensors
strategically located
on the vehicle detect that the
vehicle is suddenly stopping as a result
of a crash. These
sensors complete an electrical circuit, triggering a
chemical reaction
of the sodium azide sealed in the
inflator. The reaction produces nitrogen gas, which
inflates the cloth bag. The inflator, cloth bag, and related
hardware are all part of the air bag inflator module
packed inside the steering wheel.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel.
The air bag supplements the protection provided by
safety belts. Air bags distribute the force
of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. But air bags would not
provide protection in many types
of collisions, including
rollovers and rear and side impacts, primarily because
an occupant’s motion is not toward the air bag. Air bags
should never be regarded as anything more than a
supplement
to safety belt protection in moderate to
severe frontal and near-frontal collisions.
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. 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. There will be small amounts
of smoke coming
from vents in the deflated air bag. 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. The
nitrogen gas used to inflate the air bag will have vented
into the passenger compartment, and the bag will be
deflated within seconds after the collision. Nitrogen
,makes up about
80% of the air we breathe and is not
hazardous. As the nitrogen vents from the bag, small
particles are also vented into the passenger
compartment.

Theft
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?
Put your valuables in a storage area, like your trunk

0 Then take the door key with you.
Universal Theft Deterrent (Option)
If your Buick has this option, it has a theft deterrent
alarm system. With this system, the “SECURITY’’ light
will flash as
you open the door (if your ignition is off).
This light reminds you
to arm the theft deterrent system.
Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
Remote Keyless Entry System. The “SECURITY”
light should come on
and stay on.
3. Close all doors. The “SECURITY” light should go
off.
If a door or the trunk is opened without the key or
Remote Keyless Entry System, the alarm will
go off. It
will also
go off if a door lock or the trunk lock is
damaged. Your vehicle’s lights will flash and the horn

This lock gives you five different positions.
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 a
theft deterrent
feature.
The other positions let you perform these functions:
ACC: Accessory lets you use things like the radio and
the windshield wipers when the engine is off. To get into
“Acc”, push in the key and turn it toward

steering wheel will remain locked, just as it was before
you inserted the key.
OFF: This position lets you turn off the engine but still
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 (for example, if your
car is being pushed).
RUN: This is the position for driving.
START This position starts your engine.
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.

0 Optional Astroroof
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.

Power Windows
I
Your power window controls are on the armrest. The
switch for the driver’s window has an express-down
feature. Pull the switch back all
the way, release it and
the window will lower automatically.
To stop the
window from lowering, push the switch forward.
To
partially open the window, pull the switch back and
quickly release it.
You may
also have a lock out button. Push LOCK to
disable the power window switches. This will prevent
passengers
from opening and closing the windows. The
driver can still control all the windows
with the switch
in the locked position. Push UNLOCK to allow your
passengers to be able to use their window switches
again.
Horn
To sound the horn, press a pad with the horn symbol on
either side
of the steering wheel.
Tilt Wheel

I
A tilt steering wheel
allows you to adjust the
steering wheel before
you drive.
You can also raise it to the highest level to give your
legs more room when
you exit and enter the vehicle.
To
tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to
a comfortable level,
then release the lever to lock
the wheel in place.

Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you ‘can steer and brake at the same time.
In many emergencies, steering can help you more than
even the very best braking.

Power Steering
If you lose power steering assist because the engine
stops
or the system fails to function, you can steer but it
.will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s
why:
Experienced driver or beginner, each.of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to changejts path when you
turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this. The
traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at
which the curve is banked, and your speed. While
you’re in a curve, speed is the one factor you can
control.
Suppose you’re steering through a sharp curve. Then
you suddenly accelerate.
Those two control systems
-- steering .and acceleration --
can overwhelm those places where the tires meet the
road and make you lose control.
What should you do
if this ever happens? Let up on the
.accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves
warn that you should
adjust your speed. Of course,
the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust
your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
176 I
ProCarManuals.com

When you drive into a curve at night, it’s harder to see
the road ahead of you because it bends away from the
straight beams of your lights. This is one good reason to
drive slower.
Steering in Emergencies
There are timi% when steering can be more effective
than braking. For example,
you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right
in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can’t; there isn’t room. That’s
the time for evasive action
-- steering around the
problem.
Your Buick can perform very well
in emergencies like
these. First apply your brakes. It is better to remove as
much speed as you can from a possible collision. Then
steer around the problem, to the left or right depending
on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once you have
avoided the object. You must then be prepared to steer
back
to your original lane and then brake to a controlled
stop.
Depending on your speed, this can be rather violent for
an unprepared driver. This is one of the reasons driving
experts recommend
that you use your safety belts and
keep both hands on the steering wheel.
I
D
The fact that such emergency situations are always
possible
is a good reason to practice defensive driving at
all times.

Off-Road Recovery
You may find sometime that your right wheels have
dropped
off the edge of a road onto the shoulder while
you’re driving.
If the level
of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up
to 1/4 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel to
go straight down the roadway.
If the shoulder appears to be about four inches
(100 mm) or more below the pavement, this difference
can cause problems.
If there is not enough room to pull
entirely onto the shoulder and stop, then follow the same
procedures. But
if the right front tire scrubs against the
side
of the pavement, do NOT steer more sharply. With
too much steering angle, the vehicle may jump back
onto the road with
so much steering input that it crosses
over into the oncoming traffic before you can bring it
back under control.
Instead, ease off again on the accelerator and steering
input, straddle
the pavement once more, then try again.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back
into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds.
A miscalculation, an error in
judgment, or a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst
of all traffic accidents -- the head-on collision.
