The frontal airbags (driver and right front passenger) are
not intended to in ate during vehicle rollovers, rear
impacts, or in many side impacts because in ation
would not likely help the occupants.
In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair costs
were. In ation is determined by the angle of the
impact and how quickly the vehicle slows down in frontal
or near-frontal impacts.
What Makes an Airbag In ate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
in ator, which in ates the airbag. The in ator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger.
How Does an Airbag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Airbags supplement the protection
provided by safety belts. Airbags distribute the force
of the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But airbags
would not help you in many types of collisions,
including rollovers, rear impacts and many side impacts,
primarily because an occupant’s motion is not toward
those airbags. Airbags should never be regarded
as anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near-frontal
collisions.
What Will You See After an Airbag
In ates?
After an airbag in ates, it quickly de ates, so quickly
that some people may not even realize the airbag
in ated. Some components of the airbag module — the
steering wheel hub for the driver’s airbag, or the
instrument panel for the right front passenger’s
bag — will be hot for a short time.

California Fuel
If your vehicle is certi ed to meet California Emission
Standards (see the underhood emission control label), it
is designed to operate on fuels that meet California
speci cations. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
speci cations, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on and your vehicle may fail a smog-check test. See
Malfunction Indicator Lamp on page 3-32. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. In most cases, you should not have to add
anything to your fuel. However, some gasolines contain
only the minimum amount of additive required to
meet U.S. Environmental Protection Agency regulations.
General Motors recommends that you buy gasolines
that are advertised to help keep fuel injectors and intake
valves clean. If your vehicle experiences problems
due to dirty injectors or valves, try a different brand of
gasoline. Also, your GM dealer has additives that
will help correct and prevent most deposit-related
problems.
