How does an air bag restrain?
[n moderate to severe frontal or
near-frontal collisions,
even belted
occupants can contact
the steering wheel
or the instrument panel. The air bag
supplements 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 provide protection in many
types of collisions, including rollovers
and rear and side impacts, primarily
because an occupant’s motion
is not
toward
the air bag. Air bags should never
be regarded as anything more than a
supplement to safety belt protection
in
moderate to severe frontal and
near-frontal collisions.
What will you see after an air bag
inflation?
After the air bag has inflated, it will then
quickly deflate. This occurs
so quickly
that some people may not even realize
that the air bag inflated. The air bag will
not impede the driver’s vision or ability
to steer the vehicle, nor will
it hinder the
occupants from exiting the vehicle. There
will be small amounts of smoke coming
from vents
in the deflated air bags. Some
components of the air bag module
in the
steering wheel hub for the driver’s air bag
or the instrument panel for the
passenger’s bag may be hot for a short

ime, but the portion of the bag that comes
nto contact with you will not be hot to
he touch. The nitrogen gas used to inflate _._ .~ ~
he air bag will have vented into the
Iassenger compartment, and the bag will
Je deflated within seconds after the
:ollision. Nitrogen makes
up about 80%
3f the air we breathe and is not hazardous.
As the nitrogen vents from the bag, small
particles are also vented into the
passenger compartment.
In many crashes severe enough to inflate
an air bag, windshields are broken by
vehicle deformation. Additional
windshield breakage may occur
in
vehicles with passenger air bags because
the windshield acts as a reaction surface

Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to be
of
top quality and work well together if the
vehicle is to have really good braking.
Vehicles we design and test have
top-quality
GM brake parts in them, as
your Chevrolet does when it is
new.
When you replace parts of your braking
system
- for example, when your brake
linings wear down and you have to have
new ones put in
- be sure you get new
genuine GM replacement parts. If you
don’t, your brakes may no longer work
properly. For example, if someone puts
in
brake linings that are wrong for your
vehicle, the balance between your front
and rear brakes
can change, for the worse.
The braking performance you’ve come to
expect can change in many other ways if
someone puts
in the wrong replacement
brake parts.
Battery
Every new Chevrolet has a Delco
Freedoma battery.
You never have to add
water to one of these. When it’s time for a
new battery, we recommend a Delco
Freedom@ battery. Get one that has the
catalog number shown
on the original
battery’s label.
