2009 GMC SIERRA lock

Center Seat
Your vehicle may have a front center seat. The seatback
doubles as an armrest and cupholder/storage area for the
driver and passenger when the center seat is not used.
Do not use it as a seating position when the seatback is
folded down.
Rear Seats
Rear Seat Operation (Extended Cab)

the seat cushion while
pulling down on the
release strap, located
under the seat cushion.

Sit up straight and always keep your feet on the oor in
front of you. 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 on
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 shoulder belt locks if there is a sudden stop or
crash.

Lap-Shoulder Belt
If your vehicle is a regular cab, then all seating positions
in the vehicle have a lap-shoulder belt. If your vehicle is a
crew or extended cab, then all seating positions in the
vehicle have a lap-shoulder belt except for the center
front passenger position (if equipped), which has a lap
belt. SeeLap Belt (Crew and Extended Cab) on
page 1-36for more information.
The following instructions explain how to wear a
lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you
can sit up straight. To see how, see “Seats” in
the Index.
2. 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.
If the shoulder portion of a passenger belt is pulled
out all the way, the child restraint locking feature
may be engaged. If this happens, let the belt
go back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system. SeePassenger
Sensing System on page 1-84for more information.If the belt stops before it reaches the buckle, when
using the lap-shoulder belt in a rear center seating
position of a crew-cab, tilt the latch plate and keep
pulling the safety belt until it can be buckled.

On the extended cab,
push down on the release
button (A) and move
the height adjuster to
the desired position.
You can move the adjuster up just by pushing up on the
shoulder belt guide.
After you move the adjuster to where you want it, try
to move it down, without squeezing the buttons for the
regular and crew cabs, or without pushing the release
button for extended cabs, to make sure it has locked into
position.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 1-91. Extended Cab

Do not secure a child restraint in a position without a
top tether anchor if a national or local law requires that
the top tether be attached, or if the instructions that
come with the child restraint say that the top tether
must be attached.
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. SeeWhere to Put the Restraint
on page 1-48for additional information.
Securing a Child Restraint Designed for
the LATCH System
{CAUTION:
If a LATCH-type child restraint is not attached to
anchors, the child restraint will not be able to
protect the child correctly. In a crash, the child
could be seriously injured or killed. Install a
LATCH-type child restraint properly using the
anchors, or use the vehicle’s safety belts to secure
the restraint, following the instructions that came
with the child restraint and the instructions in this
manual.
{CAUTION:
Do not attach more than one child restraint to a
single anchor, except for the center top tether
anchors in the crew and extended cabs. Attaching
more than one child restraint to a single anchor
could cause the anchor or attachment to come
loose or even break during a crash. A child or
others could be injured. To reduce the risk of
serious or fatal injuries during a crash, attach only
one child restraint per anchor.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle any
unused safety belts behind the child restraint so
children cannot reach them. Pull the shoulder belt
all the way out of the retractor to set the lock, if
your vehicle has one, after the child restraint has
been installed.

4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.5. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. When installing a forward-facing
child restraint, it may be helpful to use your knee
to push down on the child restraint as you tighten
the belt.
