2004 GMC SIERRA Owner's Manual

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
(Extended Cab and Crew Cab)
Lap-Shoulder Belt
Here's how to wear a lap-shoulder belt properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.

2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
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
Safety Belt
Extender on page 1-32.
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.
1-28

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.
The safety belt also locks if you pull the belt very
quickly out of the retractor.
{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 ®t against your body.

To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear seat comfort guides provide added safety belt
comfort for older children who have outgrown booster
seats and for small adults. When installed on a shoulder
belt, the comfort guide better positions the belt away
from the neck and head.
There is one guide for each outside passenger in the
rear seat. Here's how to install a comfort guide and use
the safety belt:
1. Remove the guide from its storage clip on the
interior body.
1-30

2. 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 ¯at.
The guide must be on top of the belt.
1-31

4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-27.
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 of the
guides. Slide the guide onto the storage clip.
Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt isn't long enough to fasten, your
dealer will order you an extender. It's free. When you go
in to order it, take the heaviest coat you will wear, so
the extender will be long enough for you. The extender
will be just for you, and just for the seat in your
vehicle that you choose. Don't let someone else use it,
and use it only for the seat it is made to ®t. To wear
it, just attach it to the regular safety belt.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A:If possible, an older child should wear a
lap-shoulder belt and get the additional restraint a
shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap belt
should ®t snugly below the hips, just touching the
top of the thighs. It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in a crash.
Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
1-33

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can't properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child's face or neck?
A:If the child is sitting in a rear outside seat position,
move the child toward the center of the vehicle. See
Rear Safety Belt Comfort Guides for Children and
Small Adults on page 1-30
. If the child is sitting in
the center rear seat position of a crew cab, move
the child toward the safety belt buckle. In either
case be sure that the shoulder belt still is on the
child's shoulder, so that in a crash the child's upper
body would have the restraint that belts provide.
If the child is so small that the shoulder belt is still
very close to the child's face or neck, you might want
to place the child a seat that has a lap belt, if your
vehicle has one.
