GMC SIERRA 2007 Owner's Guide

Rear Seat Operation (Split Bench)
Folding Rear Seat
On a vehicle with a second row 60/40 split seat
either side of the rear seat may be folded for
added cargo space.
Notice:Folding a rear seat with the safety
belts still fastened may cause damage to the
seat or the safety belts. Always unbuckle
the safety belts and return them to their normal
stowed position before folding a rear seat.
Make sure that nothing is on the seat.
To fold the seat, slowly pull the seat cushion up.
To return the seat to the normal seating position,
slowly pull the seat cushion down.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not
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.
Make sure that the safety belt buckles on the
driver’s side seatback are accessible to the
outboard and center occupant and are not under
the seat cushions.

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:
Do not let anyone ride where he or she
cannot wear a safety belt properly. If you
are in a crash and you are 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.
{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 allow people 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.

Reminder Light on
page 249.

In most states and in all Canadian provinces,
the law says to wear safety belts. Here is
why:They work.
You never know if you will be in a crash. If you
do have a crash, you do not 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
would not 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 40 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 is just a
seat on wheels.
23

Put someone on it. Get it up to speed. Then stop the vehicle. The
rider does not stop.
24

The person keeps going until stopped by
something. In a real vehicle, it could be the
windshield...or the instrument panel...
25

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 is why safety belts
make such good sense.
Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after an
accident if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a
safety belt or not. But you can unbuckle a
safety belt, even if you are 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 airbags, why should I
have to wear safety belts?
A:Airbags are supplemental systems only; so
they workwithsafety belts — not instead of
them. Every airbag system ever offered
for sale has required the use of safety belts.
Even if you are in a vehicle that has airbags,
you still have to buckle up to get the most
protection. That is true not only in frontal
collisions, but especially in side and other
collisions.
26

Q:If I am 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 are
in an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not 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.
How to 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, see
Older Children on page 45orInfants and Young
Children on page 48. Follow those rules for
everyone’s protection.
First, you will want to know which restraint
systems your vehicle has.
We will start with the driver position.

Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To
see how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across
you. Do not let it get twisted.The lap-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.
4. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough,
seeSafety Belt Extender on page 44.
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. Move the shoulder belt height adjuster to the
height that is right for you. Improper shoulder
belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
Shoulder Belt Height Adjustment on page 35.
28

6. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully
tighten the lap belt on smaller occupants.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 would 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 is a sudden stop
or crash.
29

Q:What is wrong with this?
A:The shoulder belt is too loose. It will not 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
t against your body.
