What Makes an Airbag Inate?
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 inflator, which
inflates the airbag. The inflator, the airbag and related
hardware are all part of the airbag modules. Frontal
airbag modules are located inside the steering wheel and
instrument panel. For seating positions with side impact
airbags, there are also airbag modules in the side of the
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 many
frontal or near frontal collisions, 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 frontal
airbags, and only in moderate to severe side collisions for
vehicles with a side impact airbag.
What Will You See After an Airbag
Inates?
After the airbag inflates, it quickly deflates, so quickly
that some people may not even realize the airbag
inflated. Some components of the airbag module may
be hot for a short time. These components include
the steering wheel hub for the driver’s frontal airbag and
the instrument panel for the right front passenger’s
frontal airbag. For seating positions with side impact
airbags, the side of the seatback closest to the door may
be hot. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.
There will be some smoke and dust coming from the
vents in the deflated airbags. Airbag inflation does
not prevent the driver from seeing out of the windshield
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.

Gasoline Octane
Use regular unleaded gasoline with a posted octane
rating of 87 or higher. If the octane rating is less than 87,
you may notice an audible knocking noise when you
drive, commonly referred to as spark knock. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. If you are using gasoline rated at
87 octane or higher and you hear heavy knocking, your
engine needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specification D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT).
General Motors recommends against the use of
gasolines containing MMT. SeeAdditives on page 5-6
for additional information.
California Fuel
If your vehicle is certified to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specifications. 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 specifications, 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 3-37. 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.

{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-37.
Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or
on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping gasoline.

Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 5-48.
For any bulb changing procedure not listed in this
section, contact your dealer.
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

Headlamps
To replace a headlamp bulb, do the following:
1. Open the hood. SeeHood Release on page 5-10
for more information.
2. For wagon models, remove the two bolts from the
top of the headlamp assembly and one nut on the
inside that retains the headlamp assembly.
For hatchback models, remove the four screws and
the radiator grill. Then remove the three bolts
and the headlamp assembly.
3. Disconnect the wiring harness connector from the
