GMC YUKON XL 2002 Service Manual

1-34 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.

1-35Q: 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.

1-36Q: 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.

1-37Q: What's wrong with this?
A: The belt is over an armrest. CAUTION: You can be seriously injured if your belt goes
over an armrest like this. The belt would be much
too high. In a crash, you can slide under the belt.
The belt force would then be applied at the
abdomen, not at the pelvic bones, and that could
cause serious or fatal injuries. Be sure the belt
goes under the armrests.

1-38Q: 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.

1-39Q: 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.

1-40 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.

1-41The 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.

1-42 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 designed to work with safety belts but
don't replace them.
CAUTION: (Continued) 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 or low
- speed frontal crashes,
or in many side crashes. And, for some
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.

1-43CAUTION: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. 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.
