belt GMC YUKON 2000 User Guide

1-22
Pull up on the latch plate to make sure it is secure.
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.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
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.

Q:What's wrong with this?
A:The shoulder belt is too loose. It won't give nearly
as much protection this way.
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.

1-24
Q:What's wrong with this?
A:The belt is buckled in the wrong place.
CAUTION:
You can be seriously injured if your belt is buckled
in the wrong place like this. In a crash, the belt
would go up over your abdomen. The belt forces
would be there, not at the pelvic bones. This could
cause serious internal injuries. Always buckle your
belt into the buckle nearest you.

1-25
Q:What's wrong with this?
A:The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
CAUTION:
You can be seriously injured if you wear the
shoulder belt under your arm. In a crash, your
body would move too far forward, which would
increase the chance of head and neck injury.
Also, the belt would apply too much force to the
ribs, which aren't as strong as shoulder bones.
You could also severely injure internal organs
like your liver or spleen.

1-26
Q:What's wrong with this?
A:The belt is twisted across the body.
CAUTION:
You can be seriously injured by a twisted belt.
In a crash, you wouldn't have the full width
of the belt to spread impact forces. If a belt is
twisted, make it straight so it can work properly,
or ask your dealer to fix it.

1-27
To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage both the
belt and your vehicle.
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to
be seriously injured if they don't wear safety belts.
A pregnant woman should wear a lap-shoulder belt,
and the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.

1-28
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety belt
properly, see ªDriver Positionº earlier in this section.
The right front passenger's safety belt works the same
way as the driver's safety belt
-- except for one thing.
If you ever pull the shoulder portion of the belt out
all the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Air Bag Systems
This part explains the frontal and side impact air
bag systems.
Your vehicle has four air bags
-- a frontal air bag for
the driver, another frontal air bag for the right front
passenger, a side impact air bag for the driver, and
another side impact air bag for the right front passenger.Frontal air bags are designed to help reduce the risk
of injury from the force of an inflating frontal air bag.
But these air bags must inflate very quickly to do their
job and comply with federal regulations.
Here are the most important things to know about the
air bag systems:
CAUTION:
You can be severely injured or killed in a crash if
you aren't wearing your safety belt
-- even if you
have air bags. Wearing your safety belt during a
crash helps reduce your chance of hitting things
inside the vehicle or being ejected from it. Air
bags are ªsupplemental restraintsº to the safety
belts. All air bags are designed to work with
safety belts but don't replace them.
CAUTION: (Continued)

1-29
CAUTION: (Continued)
Frontal air bags for the driver and right front
passenger are designed to work only in moderate
to severe crashes where the front of your vehicle
hits something. They aren't designed to inflate
at all in rollover, rear, side or low
-speed frontal
crashes. And, for unrestrained occupants,
frontal air bags may provide less protection in
frontal crashes than more forceful air bags have
provided in the past. The side impact air bags
for the driver and right front passenger are
designed to inflate only in moderate to severe
crashes where something hits the side of your
vehicle. They aren't designed to inflate in
frontal, in rollover or in rear crashes.
Everyone in your vehicle should wear a
safety belt properly
-- whether or not there's
an air bag for that person.
CAUTION:
Both frontal and side impact air bags inflate
with great force, faster than the blink of an eye.
If you're too close to an inflating air bag, as you
would be if you were leaning forward, it could
seriously injure you. Safety belts help keep you
in position for air bag inflation before and during
a crash. Always wear your safety belt, even with
frontal air bags. The driver should sit as far back
as possible while still maintaining control of the
vehicle. Front occupants should not lean on or
sleep against the door.

1-30
CAUTION:
Anyone who is up against, or very close to, any
air bag when it inflates 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 the part of this
manual called ªChildren.º
There is an air bag readiness
light on the instrument
panel, which shows the
air bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

When should an air bag inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal or
near
-frontal crashes. The frontal air bags are designed
to inflate only if the impact speed is above the system's
designed ªthreshold level.º 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 specific
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 driver's and right
front passenger's frontal air bags are not designed
to inflate in rollovers, side impacts, or rear impacts,
because inflation would not help the occupant.
The side impact air bags are designed to inflate in
moderate to severe side crashes involving a front door.
A side impact air bag will inflate if the crash severity
is above the system's designed ªthreshold level.º
The threshold level can vary with specific vehicle
design. Side impact air bags are not designed to inflate
in frontal or near
-frontal impacts, rollovers or rear
impacts, because inflation would not help the occupant.
A side impact air bag will only deploy on the side of the
vehicle that is struck.In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near
-frontal impacts. For side impact air
bags, inflation is determined by the location and severity
of the impact.
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 ªOff
-Road
Drivingº in the Index for more tips on off
-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware
are all part of the air bag modules inside the steering
wheel, instrument panel and the side of the front
seatbacks closest to the door.
