Downloaded from www.Manualslib.com manuals search engine 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. 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. 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
time, but the portion of the bag that comes
into contact .with you will not be hot to
the touch. There will be small amounts of
smoke coming from vents in the deflated
air bags. The air bag will
rn impede the
driver’s vision or ability to steer the
vehicle, nor will
it hinder the occupants
from exiting the vehicle.
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
for the inflating air bag.
0 The air bags are designed to inflate only
once. After they inflate you’ll need some
new parts for your air bag system.
If you
don’t get them, the air bag system won’t
be there to help protect you
in another
crash.
A new system will include air bag
modules and possibly other parts. The
service manual has information about the
need to replace other pans.
Your vehicle is equipped with a
diagnostic module. which records
information about the air bag system if
the air bag deploys
in a crash. The
module records information about the
readiness of the system, which sensors
activated the deployment, and whether
thr
driver’s safety belt was in use.
Let only qualified technicians work on
your air bag system. Improper service car
mean that your air bag system won’t work
properly. See your dealer for service.
If you damage the cover for the driv-
er’s
or the right-front passenger’s air
bag, they may not work properly.
You may have
tu replace the air bag
on the steering wheel or both the air
bag and the instrument panel for the
passenger’s air bag.
Do not open or

You can match a transmitter to as many
different vehicles
as you own, provided
they are equipped with exactly
the same
model system. (General Motors offers
several different models of these systems
on their vehicles.) Each vehicle can have
only two transmitters matched to
it.
To match transmitters to your vehicle:
1. Find the Data Link Connector (DLC).
It is
in the bottom of the instrument
panel near the steering column.
2. Insert one end of a fused jumper into
terminal
“G.” Terminal “G” is the top
terminal on the far right.

“A” is the bottom terminal on the far

and unlock within one to three seconds.
When matching transmitters, the first
transmitter code matched
will be stored in
both memories until a second transmitter
is matched. This means
that the second transmitter
will not work until
it is
matched
in step 5.
4. Press any button on the first
transmitter. The door locks should
lock and unlock.

transmitter. The door locks should
lock and unlock.

will not work unless
the jumper
is removed.

rather not match the transmitters yourself,
see your Chevrolet dealer.
Battery Replacement
Under normal use, the batteries in your
key chain transmitter should last about

You can tell the batteries are weak if the

in any location. If you have to get

to your vehicle before the
:ransmitter works, it’s probably time to

If you have rear drum brakes, they don’t
have wear indicators, but
if you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear
brake drums should be removed and
inspected each time the tires are removed
for rotation or changing. When you have
the front brakes replaced, have
the rear
brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or
if there is a
rapid increase in pedal travel. This could
be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake
stop, your disc brakes adjust for wear.
If
you rarely make a moderate or heavier
stop, then your brakes might not adjust
correctly.
If you drive in that way, then -
very carefully - make a few moderate
brake stops about
every 1,000 miles
(I 600 km), so your brakes will adjust
properly.
. . .204
If your brake pedal goes down farther
than normal, your rear drum brakes may
need adjustment. Adjust them by backing
up and firmly applying the brakes
a few
times.
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
Freedoms battery.
You never have to add
water to one of these. When it’s time for a
new battery, we recommend a Delco
Freedoma battery. Get one that has the
catalog number shown on the original
battery’s label.
Vehicle Storage
If you’re not going to drivi your vehicle
for
25 days or more, take off the black,
negative
(-) cable from the battery. This
will help keep your battery from running
down.
