2010 GMC SIERRA lock

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
Regular and Crew CabTo move the adjuster
down for the regular and
crew cabs, squeeze the
buttons (A) on the sides of
the height adjuster and
move the height adjuster
to the desired position.
Extended CabOn 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.

{WARNING:
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.
{WARNING:
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.Notice:
Do not let the LATCH attachments rub
against the vehicle’ s safety belts. This may damage
these parts. If necessary, move buckled safety belts
to avoid rubbing the LATCH attachments.
Do not fold the empty rear seat with a safety belt
buckled. This could damage the safety belt or the
seat. Unbuckle and return the safety belt to its
stowed position, before folding the seat.

Driver Side shown, Passenger Side similar
If the vehicle has roof-rail airbags for the driver, right
front passenger, and second row outboard passengers,
they are in the ceiling above the side windows.
{WARNING:
If something is between an occupant and an
airbag, the airbag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the steering
wheel hub or on or near any other airbag
covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side impact
airbag.
Never secure anything to the roof of a vehicle
with roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inflating roof-rail airbag will be
blocked.

The vehicle has a feature that may automatically unlock
the doors, turn on the interior lamps and hazard warning
flashers, and shut off the fuel system after the airbags
inflate. You can lock the doors, turn off the interior
lamps and hazard warning flashers by using the
controls for those features.
{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
.Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the
airbag system will not be there to help protect you
in another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and diagnostic
module which records information after a crash.
See
Vehicle Data Recording and Privacy
on
page 8‑18and Event Data Recorderson
page 8‑18.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
