belt CHEVROLET S10 2003 2.G Service Manual

{CAUTION:
Air bags in¯ate with great force, faster than the
blink of an eye. If you're too close to an
in¯ating air bag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position before
and during a crash. Always wear your safety
belt, even with air bags. The driver should sit
as far back as possible while still maintaining
control of the vehicle.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it in¯ates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle's safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see
Older Children on page 1-30 and Infants
and Young Children on page 1-32.

When Should an Air Bag In¯ate?
An air bag is designed to in¯ate in a moderate to severe
frontal, or near-frontal crash. The air bag will in¯ate
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 9 to 16 mph (14 to 26 km/h). The threshold
level can vary, however, with speci®c 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 in¯ate in rollovers,
rear impacts, or in many side impacts because in¯ation
would not help the occupant.
In any particular crash, no one can say whether an air
bag should have in¯ated simply because of the damage
to a vehicle or because of what the repair costs were.
In¯ation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See
Off-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-14
for more tips on off-road driving.
What Makes an Air Bag In¯ate?
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
in¯ator, which in¯ates the air bag. The in¯ator, 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 many
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.

·Air bags are designed to in¯ate only once. After
they in¯ate, 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 for your vehicle covers the need to
replace other parts.
·Your vehicle is equipped with a diagnostic module,
which records information about the air bag
system. The module records information about the
readiness of the system, when the system
commands air bag in¯ation and driver's safety belt
usage at deployment.
·Let only quali®ed technicians work on your air bag
system. Improper service can mean that an air
bag system won't work properly. See your dealer
for service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger's air bag. Do not open or
break the air bag coverings.
Air Bag Off Switch
Regular Cab and Extended Cab Models
If your vehicle is a regular cab model or an extended
cab model, it has a switch on the instrument panel
that you can use to turn off the right front passenger's
air bag.
1-61

This switch should only be turned to AIR BAG OFF if
the person in the right front passenger's position is
a member of a passenger risk group identi®ed 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 air bag to pose a special risk
for the passenger; and
·makes the potential harm from the passenger air
bag in a crash greater than the potential harm
from turning off the air bag and allowing the
passenger, even if belted, to hit the dashboard or
windshield in a crash.
{CAUTION:
If the right front passenger's air bag is turned
off for a person who isn't in a risk group
identi®ed by the national government, that
person won't have the extra protection of an
air bag. In a crash, the air bag wouldn't be able
to in¯ate and help protect the person sitting
there. Don't turn off the passenger's air bag
unless the person sitting there is in a risk
group. See ªAir Bag Off Switchº in the Index.

Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's
basic structure isn't changed, it's not likely to keep
the air bags from working properly in a crash.
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags 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 air bag system
from working properly. Also, the air bag system
may not work properly if you relocate any of the air
bag 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 the
Customer Satisfaction
Procedure on page 7-2
.
Restraint System Check
Checking Your 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 air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
1-65

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've 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 you ever see a label on
the driver's or the right
front passenger's safety
belt that says to replace
the belt, be sure to do so.
Then the new belt will
be there to help protect
you in a collision. You
would see this label on the
belt near the door
opening.
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 wasn't being used at the time of
the collision.
If an air bag in¯ates, you'll need to replace air bag
systems parts. See the part on the air bag system earlier
in this section.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
·Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
·Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle:
·You can use the keyless entry system, if your
vehicle has this feature.
·You can use your key to unlock your door from the
outside.
·You can use the power lock switch (if equipped) to
lock or unlock the doors.
To manually lock a door
from the inside, slide the
manual lever on your
door down. To manually
unlock a door from
the inside, slide the lever
on the door up.
·You will see a colored area on the lever when the
door is unlocked.

Tachometer
The tachometer (if equipped) displays the engine speed
in revolutions per minute (rpm).
Notice:On vehicles with a manual transmission, if
you operate the engine with the tachometer in
the shaded warning areas, your vehicle's engine or
other parts of your vehicle could be damaged.
Damage to your engine or vehicle caused by
operating the engine with the tachometer in the
shaded warning areas isn't covered by your vehicle
warranty. Don't operate the tachometer in the
shaded warning areas.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ¯ash for several
more.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
3-26

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger's air bag
could in¯ate even though the switch is off. If
this ever happens, don't let anyone whom the
national government has identi®ed as a
member of a passenger air bag risk group sit
in the right front passenger's position (for
example, don't secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced.
Charging System Light
The charging system light
will come on brie¯y when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
