Your vehicle may or may not have side impact airbags.
SeeAirbag System on page 1-47. Side impact
airbags are designed to in ate in moderate to severe
side crashes. A side impact airbag will in ate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with speci c vehicle
design. Side impact airbags are not designed to
in ate in frontal or near-frontal impacts, rollovers or rear
impacts, because in ation would not likely help the
occupant. A side impact airbag will only deploy on the
side of the vehicle that is struck.
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. For frontal airbags, in ation is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal or near-frontal impacts. For side
impact airbags, in ation is determined by the location
and severity of the impact.
What Makes an Airbag In ate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For
both frontal and side impact airbags, 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 thesteering wheel and the instrument panel. For vehicles
with side impact airbags, the modules are located in the
side of the front seatbacks closest to the door or the
ceiling of the vehicle, near the side windows.
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. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements 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 the
frontal 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 the airbag. Side impact airbags would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear 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 for the driver’s and right front passenger’s
frontal airbags, and only in moderate to severe
side collisions for side impact airbags.

California Fuel
If your vehicle is certi ed to meet California Emission
Standards, it is designed to operate on fuels that
meet California speci cations. See the underhood
emission control label. 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. SeeMalfunction Indicator Lamp on
page 3-31. 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.
