If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there's no crash. You would have to
replace the air bags as well as the sensors and related
parts. If your vehicle is ever in a flood, or if it's exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning off the vehicle immediately and
disconnecting the battery cables. Don't let anyone start
the vehicle under any circumstances. See your dealer
for service.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
dealer and the GM service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.
The air bag system does not need regular maintenance.

1-36 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 in this manual.
See ªCustomer Satisfaction Procedureº in the Index.)
Center Passenger Position
Lap Belt
If your vehicle has front and rear bench seats, someone
can sit in the center positions.

1-37
When you sit in a center seating position, you have a lap
safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. If the belt isn't long enough,
see ªSafety Belt Extenderº at the end of this section.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt quickly
if you ever had to.

Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
Lap-Shoulder Belt
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.

1-39
When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you'd be less
likely to slide under the lap belt. If you slid under it, the
belt would apply force at your abdomen. This could
cause serious or even fatal injuries. The shoulder belt
should go over the shoulder and across the chest.
These parts of the body are best able to take belt
restraining forces.
The safety belt locks if there's a sudden stop or a crash.

Four-door utility models and the second seat of
Suburbans have shoulder belt height adjusters. Move the
shoulder belt height adjuster to the height that is right
for you.To move the height adjuster down, push in at the word
PRESS and move the height adjuster to the desired
position. You can move the adjuster up just by
pushing up on the shoulder belt guide. After you
move the adjuster to where you want it, try to move
it down without pushing in to make sure it has locked
into position.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should be
away from your face and neck, but not falling off
your shoulder.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.

To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Your vehicle may have rear shoulder belt comfort guides.
This feature will provide added safety belt comfort for
children who have outgrown child restraints and for small
adults. When installed on a shoulder belt, the comfort
guide pulls the belt away from the neck and head.There is one guide for each outside passenger position in
the rear seat. To provide added safety belt comfort for
children who have outgrown child restraints and for
smaller adults, the comfort guides may be installed on
the shoulder belts. Here's how to install a comfort guide
and use the safety belt:
1. Remove the guide from its storage clip on the side of
the seatback.

1-42
2. Slide the guide under and past the belt. The elastic
cord must be under the belt. Then, place the guide
over the belt, and insert the two edges of the belt into
the slots of the guide.3. Be sure that the belt is not twisted and it lies flat.
The elastic cord must be under the belt and the guide
on top.

1-43
4. Buckle, position and release the safety belt as
described in ªRear Seat Outside Passenger Positionsº
earlier in this section. Make sure that the shoulder
belt crosses the shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out from
the guides. Slide the guide onto the storage clip.
Make sure you remove the comfort guide from the belt
before you fold a rear seat down or use an easy
-entry
seat, if your vehicle has one.
Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. Neither
the distance traveled nor the age and size of the traveler
changes the need, for everyone, to use safety restraints.
In fact, the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Smaller Children and Babies
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. This is true even though your vehicle
has Next Generation frontal air bags. 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.

yellowblue
1-44
CAUTION:
Smaller children and babies should always be
restrained in a child or infant restraint. The
instructions for the restraint will say whether it is
the right type and size for your child. A very
young child's hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child's abdomen. In a crash, the belt would apply
force right on the child's abdomen, which could
cause serious or fatal injuries. So, be sure that
any child small enough for one is always properly
restrained in a child or infant restraint.
Infants need complete support, including support for
the head and neck. This is necessary because an infant's
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear
-facing restraint settles into the restraint, so the
crash forces can be distributed across the strongest part
of the infant's body, the back and shoulders. A baby
should be secured in an appropriate infant restraint.
This is so important that many hospitals today won't
release a newborn infant to its parents unless there is an
infant restraint available for the baby's first trip in a
motor vehicle.
