But don’t have a seatback reclined if your vehicle is
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can’t do their job
when you’re reclined like this.
The shoulder belt can’t do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can’t do its job either. In a crash
the belt could go up over your abdomen. The
belt forces would be there, not at your pelvic
bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.

2003 - Yukon/Yukon XL

{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won’t provide the
protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.
To reinstall the 50/50 split bench, do the following:
1. While holding the rear of the seat up, slide the front
wheels into the slots on thefloor. The front latches
should lock into place. If the latches do not lock,
try tilting the rear of the seats upwards.2. Once the latches are engaged, let the seat drop
into place. Release the lever labeled 1 to return
the seat to its upright position.
3. Push and pull on the seat to make sure it is locked
into place. The seatback cannot be raised to the
upright position unless the seat is secured to
thefloor.
Bench Seat
If your vehicle has a full bench seat, the seatback can
be folded and the seat can be tilted or removed from the
vehicle.

4. Squeeze the release lever, located in the lower
middle to unlatch the seat from thefloor while
pulling the seat out.
5. While holding the rear of the seat up, roll the seat
out of the vehicle.
Replacing the Bench Seat
{CAUTION:
If the seatback isn’t locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A seat that isn’t locked into place properly can
move around in a collision or sudden stop.
People in the vehicle could be injured. Be sure
to lock the seat into place properly when
installing it.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won’t provide the
protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.

Once the seatbacks are folded down, the rear seat
footwell area will be exposed and will have to be
covered by the loadfloor panel. To create a loadfloor,
do the following:
1. Release the panels from the seatbacks by pushing
forward on the latches.
2. Then fold the panels back to cover the rear seat
footwell area.
If you have removed the head restraints to fold the rear
bucket seat, be sure to reinstall them on the seatback
after it has been returned to the normal seating position.Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don’t let anyone ride where he or she can’t
wear a safety belt properly. If you are in a
crash and you’re not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers’ belts are
fastened properly too.

2003 - Yukon/Yukon XL

{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allowpeople to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-39.In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why:They work.
You never know if you’ll be in a crash. If you do have a
crash, you don’t know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person wouldn’t survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter... a lot!

Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it’s just a seat on
wheels.Put someone on it.

or the instrument panel...
or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.

Questions and Answers About
Safety Belts
Q:Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A:Youcouldbe–whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re upside down. And your chance
of being conscious during and after an accident,
so youcanunbuckle and get out, ismuchgreater if
you are belted.
Q:If my vehicle has air bags, why should I have to
wear safety belts?
A:Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they workwith
safety belts–not instead of them. Every air bag
system ever offered for sale has required the
use of safety belts. Even if you’re in a vehicle that
has air bags, you still have to buckle up to get
the most protection. That’s true not only in frontal
collisions, but especially in side and other
collisions.
Q:If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you’re in an
accident–even one that isn’t your fault–you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
Howto Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-44
orInfants and Young Children on page 1-46. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
