CHEVROLET EXPRESS CARGO VAN 2005 1.G Manual PDF

{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast yourvehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
Airbags may inate at different crash speeds. For
example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.
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. Ination is determined by the angle of the
impact and how quickly the vehicle slows down in front
or near-frontal impacts.

If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, your vehicle has
single stage airbags. If the GVWR is below 8,500 lb
(3 855 kg) then your vehicle has dual stage airbags. You
can nd the GVWR on the certication label on the
rear edge of the driver’s door. SeeLoading Your Vehicle
on page 4-31for more information.
Single Stage Airbags
If your vehicle has frontal airbags with single stage
deployment and your vehicle goes straight into a wall
that does not move or deform, the threshold level
is about 9 to 16 mph (14 to 26 km/h). (The threshold
level can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.)
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the restraint will adjust according to the
crash severity. Your vehicle is equipped with electronic
frontal sensors which help the sensing system
distinguish between a moderate and a more severe
frontal impact. For moderate frontal impacts, these
airbags inate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level for the
reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 16 to 25 mph (26 to 40 km/h).
(The threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above
or below this range.)
Vehicles with dual stage airbags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensors provide
information which is used to determine if the airbags
should deploy at a reduced level or at full deployment.
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
inator, which inates the airbag. The inator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger.
1-66

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. Airbags supplement 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 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 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.
What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so quickly that
some people may not even realize the airbag inated.
Some components of the airbag module — the steering
wheel hub for the driver’s airbag, or the instrument panel
for the right front passenger’s airbag —will be hot for a
short time. 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
deated airbags. Airbag ination does not prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers the need to
replace other parts.
1-67

Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that your
airbag system will not work properly. See your
dealer for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the airbag
may not work properly. You may have to replace the
airbag module in the steering wheel or both the
airbag module and the instrument panel for the right
front passenger’s airbag. Do not open or break
the airbag coverings.
Airbag Off Switch
If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, your vehicle has
an airbag off switch. You can nd the GVWR on the
certication/tire label on the rear edge of the driver’s
door. SeeLoading Your Vehicle on page 4-31for more
information.
You can use the airbag off switch on the instrument
panel to turn off the right front passenger’s airbag.United States
Canada
1-68

This switch should only be turned to airbag OFF if the
person in the right front passenger’s position is a
member of a passenger risk group identied by the
national government as follows:
Infant.An infant (less than 1 year old) must
ride in the front seat because:

my vehicle has no rear seat;
my vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
the infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:

my vehicle has no rear seat;
although children ages 1 to 12 ride in the rear seat(s)
whenever possible, children ages 1 to 12 sometimes
must ride in the front because no space is available
in the rear seat(s) of my vehicle; or
the child has a medical condition which, according to
the child’s physician, makes it necessary for the child
to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

causes the passenger airbag to pose a special risk
for the passenger; and
makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.
{CAUTION:
If the right front passenger’s airbag is turned
off for a person who is not in a risk group
identied by the national government, that
person will not have the extra protection of an
airbag. In a crash, the airbag will not be able to
inate and help protect the person sitting
there. Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group. SeeAirbag Off Switch on page 1-68.
1-69

To turn off the right front passenger’s airbag, insert your
ignition key into the switch, push in, and move the
switch to the off position.
The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The light will stay
on to remind you that the airbag is off. The right
front passenger’s airbag will remain off until you turn it
back on.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group sit in
the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. United States
Canada
1-70

To turn the right front passenger’s airbag on, insert your
ignition key into the switch, push in, and move the
switch to the on position.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-12.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid wires wrapped
with yellow tape or yellow connectors. They
are probably part of the airbag system. Be sure
to follow proper service procedures, and make
sure the person performing work for you is
qualied to do so.
The airbag system does not need regular maintenance. United States
Canada
1-71

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front of the
vehicle that could keep the airbags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep the airbag system from
working properly. Also, the airbag system may not
work properly if you relocate any of the airbag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of theCustomer Satisfaction Procedure on
page 7-2.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
1-72

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt, or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If the frontal airbags inate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle assembly if your vehicle has safety belt
pretensioners. Be sure to do so. Then the new buckle
assembly will be there to help protect you in a collision.
After a crash you may need to replace the driver and front
passenger’s safety belt buckle assemblies, even if the
frontal airbags have not deployed. The driver and front
passenger’s safety belt buckle assemblies may contain
safety belt pretensioners. If so, have your safety belt
pretensioners checked if your vehicle has been in a
collision, or if your airbag readiness light stays on after
you start your vehicle or while you are driving. SeeAirbag
Readiness Light on page 3-27.
