sensor BUICK CENTURY 1993 Owners Manual

Q: Where is the air bag?
A: The driver’s air bag is in the middle of the steering
wheel.
Q: When is an air bag expected to inflate?
A: 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 (14 and 23 km/h). 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 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.
Q: What makes an air bag inflate?
A: 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.

Headlight “On” Warning
If you open the door while leaving the lights on, you will
hear a warning chime.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Running Lights” (DRL)
are a useful feature, in
that DIU can make your vehicle more visible to
pedestrians and other drivers during daylight hours. DRL
are required on new vehicles sold in Canada.
Your DRL work with a light sensor on top
of the
instrument panel. Don’t cover it up. The low beam
headlights will come on at reduced brightness
in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released.
At dusk, the exterior. lights will come bn &.nomatically
and the low
beams will change to full brightness. At
dawn, the exterior lights will go out and the low beams
will change to
the reduced brightness of DRL (if the
headlight switch is off).
Of course, you may still turn on the headlights any time
you need to.
To idle your vehicle with DRL off, set the parking brake
while the ignition is in the
“Off’ or “Lock” position.
Then start the vehicle. The
DRL will stay off until you
release the parking brake.

Gasolines for Cleaner Air
Your use of gasoline with detergent additives will help
prevent deposits
from forming in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines
are now blended with materials called
oxygenates. General Motors recommends that you use gasolines
with these blending materials, such as MTBE
and ethanol.
By doing so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
F’uels in Foreign Countries
If you plan on driving in another country outside the U.S.
or Canada, unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at
all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that
means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact
a major oil company that does business in the country
where
you’ll be driving.
You
can also write us at the following address for advice.
Just tell us where you’re going and give your Vehicle Identification Number
(VIN) .
