Side impact airbags are designed to inate in moderate
to severe side crashes. A side impact airbag will
inate if the crash severity is above the system’s
designed “threshold level.” The threshold level can vary
with specic vehicle design. Side impact airbags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination 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 inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal and near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.
What Makes an Airbag Inate?
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 inator, which
inates the airbag. The inator, the airbag and related
hardware are all part of the airbag modules inside
the steering wheel, the instrument panel, and the side
of the front seatbacks closest to the door.
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 passenger’s frontal airbags,
and only in moderate to severe side collisions for
vehicles with a driver’s and passenger’s side impact
airbag.

Gasoline Specications
It is recommended that gasoline meet specications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specications could provide improved
driveability and emission control system performance
compared to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.
California Fuel
If your vehicle is certied to meet California Emission
Standards, it is designed to operate on fuels that
meet California specications. 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 specications, 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 3-30. 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.

Bulb Replacement
For the proper types of bulbs to use, seeReplacement
Bulbs on page 5-48.
For any bulb changing procedure not listed in this
section, contact your dealer’s service department.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas inside
and can burst if you drop or scratch the bulb.
You or others could be injured. Be sure to
read and follow the instructions on the bulb
package.
Headlamps
To replace the headlamp bulbs, do the following:
1. Turn the front wheels as far as they will go in the
opposite direction of the bulb that is being changed.
2. Reach underneath the vehicle and locate the
headlamp door. Remove the fastener retaining
the door.
3. Turn the bulb socket counterclockwise to remove
it from the headlamp assembly.
There are separate sockets for the high and
low-beam headlamps.
4. Pull the bulb socket out of the headlamp assembly.
