2010 GMC SIERRA belt

Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the
safety belt assembly. They can help tighten the safety
belts during the early stages of a moderate to severe
frontal, near frontal, or rear crash if the threshold
conditions for pretensioner activation are met. And,
if your vehicle has side impact airbags, safety belt
pretensioners can help tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle's safety belt
system. SeeReplacing Restraint System Parts After a
Crash on page 2‑94.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your
dealer/retailer. The guides may provide added safety
belt comfort for older children who have outgrown
booster seats and for some adults. When installed and
properly adjusted, the comfort guide positions the belt
away from the neck and head.

Here is how to install a comfort guide to the
shoulder belt:1. Remove the guide from its storage clip on the interior body.
2. Place the guide over the belt and insert thetwo edges of the belt into the slots of the guide.
3. Be sure that the belt is not twisted and it lies flat.The elastic cord must be under the belt and the
guide on top.
2-35

{WARNING:
A safety belt that is not properly worn may not
provide the protection needed in a crash.
The person wearing the belt could be seriously
injured. 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.
4. Buckle, position, and release the safety belt asdescribed previously in this section. Make sure that
the shoulder belt crosses the shoulder.
To remove and store the comfort guide, squeeze the
belt edges together so that the safety belt can be
removed from the guide. Slide the guide onto the
storage clip.

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 do not 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.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it is more
likely that the fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Lap Belt (Crew and Extended Cab)
This section is only for the lap belt. To learn how to
wear a lap-shoulder belt, seeLap-Shoulder Belton
page 2‑30.
Your vehicle may have a center seating position.
When you sit in the center front seating position,
you have a lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and pull it
along the belt.
Buckle, position, and release it the same way as the
lap part of a lap-shoulder belt.
2-37

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, seeSafety Belt Extender
on page 2‑38.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the safety
belt quickly if necessary.
Safety Belt Extender
If the vehicle's safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your dealer/
retailer will order you an extender. When you go in to
order it, take the heaviest coat you will wear, so the
extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and use
it only for the seat it is made to fit. The extender has
been designed for adults. Never use it for securing child
seats. To wear it, attach it to the regular safety belt.
For more information, see the instruction sheet that
comes with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.The manufacturer's instructions that come with the
booster seat state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below fit test:
.Sit all the way back on the seat. Do the knees
bend at the seat edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt. Does the shoulder
belt rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See
“Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt
on page 2‑30for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
.Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
.Can proper safety belt fit be maintained for the
length of the trip? If yes, continue. If no, return to
the booster seat.
.If you have the choice, a child should sit in a
position with a lap-shoulder belt and get the
additional restraint a shoulder belt can provide.

Q: What is the proper way to wear safety belts?
A: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 fit snugly below the
hips, just touching the top of the thighs. This applies
belt force to the child's pelvic bones in a crash.
It should never be worn over the abdomen, which
could cause severe or even fatal internal injuries in
a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 2‑30.
According to accident statistics, children and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
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.
{WARNING:
Never do this.
Never allow two children to wear the same safety
belt. The safety belt can not properly spread the
impact forces. In a crash, the two children can be
crushed together and seriously injured. A safety
belt must be used by only one person at a time.
2-40

{WARNING:
Never do this.
Never allow a child to wear the safety belt with the
shoulder belt behind their back. A child can be
seriously injured by not wearing the lap-shoulder
belt properly. In a crash, the child would not be
restrained by the shoulder belt. The child could
move too far forward increasing the chance of
head and neck injury. The child might also slide
under the lap belt. The belt force would then be
applied right on the abdomen. That could cause
serious or fatal injuries. The shoulder belt should
go over the shoulder and across the chest.
