If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating air bag must be kept clear. Don’t
put anything between an occupant and an air
bag, and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.” If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level
is
about 8 to 11 mph (13 to 18 km/h). The threshold level
can vary, however, with specific vehicle design,
so that
it can be somewhat above or below this range. If your
vehicle strikes something that will move or deform, such
as a parked car, the threshold level will be higher. The
air bag is not designed to inflate
in rollovers, side
impacts or rear impacts, because inflation would not
help the occupant. In
any particular crash,
no one can say whether an air
bag should have inflated simply because of the damage
to
a vehicle or because of what the repair costs were.
Inflation
is determined by the angle of the impact and
how quickly the vehicle slows down
in frontal or
near-frontal impacts.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle
is in a crash. The sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part
of the air bag modules inside the
steering wheel and in the instrument panel in front of the
right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the protection
provided by safety belts.
Air bags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But
air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily
because an occupant’s motion
is not toward those air
bags.
Air bags 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.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate
on fuels that meet
California specifications.
If such fuels are 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 on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If this occurs, return
to your authorized Aurora retailer for diagnosis to
determine the cause of failure. In the event
it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may
be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Aurora retailer for service. To
provide cleaner air, all gasolines in the United States
are now required
to contain additives that will help
prevent deposits from forming in your engine and
fuel system, allowing your emission control system
to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
.
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you.
If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
FYng a Portable Fuel Container
I-
Never fill 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.
CAUTION: (Continued)
I
!
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your retailer’s service department.
For the type of bulb to use, see “Replacement Bulbs” in
the Index.
Halogen Bulbs
‘ A CAUTION:
A
Exterior Front Bulbs

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.
A. Front Turn Signal
B. Headlamps
The entire front headlamp assembly must be removed to
replace
the headlamps and front turn signal bulbs. You
may find it easier
to remove the air cleaner assembly
when replacing bulbs on
the driver’s side.
If more hand clearance is required, remove the air
cleaner assembly as instructed in Steps 1 through
3
earlier in this section.
