2008 GMC Savana Owner ManualM 

To unlatch the belt, push the button on the buckle.
The belt should go back out of the way. When the
safety belt is not in use, slide the latch plate up
the safety belt webbing. The latch plate should rest
on the stitching on the safety belt, near the guide
loop on the side wall.
Before you close a door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
Shoulder Belt Height Adjuster
Your vehicle has a shoulder belt height adjuster for
the driver and right front passenger position.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should
be away from your face and neck, but not falling off
your shoulder. Improper shoulder belt height adjustment
could reduce the effectiveness of the safety belt in
a crash.
To move it down, pull on
the center adjuster control
labeled PULL. You can
move the height adjuster
up just by pushing up
on the shoulder belt guide.
After you move the height adjuster to where you want it,
try to move it down without pushing in to make sure it
has locked into position.

For passenger vans with a sliding door, on the
passenger’s side of the vehicle, you will have a separate
roof-rail airbag for the passenger seated directly behind
the right front passenger and the third row outboard
passenger position.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not in ate properly
or it might force the object into that person
causing severe injury or even death. The path
of an in ating 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.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your vehicle
by routing the rope or tie down through any
door or window opening. If you do, the path
of an in ating roof-rail airbag will be blocked.
When Should an Airbag In ate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce
the potential for severe injuries mainly to the driver’s
or right front passenger’s head and chest. However,
they are only designed to inflate if the impact exceeds
a predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash
is likely to be in time for the airbags to inflate and
help restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds.
For example:
•If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
1-62 

The parts of the airbag that come into contact with
you may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in
the deflated airbags. Airbag inflation does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people
from leaving the vehicle.
{CAUTION:
When an airbag in ates, there may be dust
in the air. This dust could cause breathing
problems for people with a history of asthma
or other breathing trouble. To avoid this,
everyone in the vehicle should get out as
soon as it is safe to do so. If you have
breathing problems but cannot get out of
the vehicle after an airbag in ates, then get
fresh air by opening a window or a door.
If you experience breathing problems
following an airbag deployment, you should
seek medical attention.Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning flashers on when the airbags inflate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning flashers off by using the
controls for those features.
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.
•Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 7-16andEvent Data Recorders on page 7-17.
•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.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.There are several ways to lock and unlock your vehicle.
If your vehicle is equipped with keyless entry, see
Remote Keyless Entry (RKE) System on page 2-3for
more information.
From the outside, use your key.
To lock the door from the
inside, slide the manual
lever on your door down.
To unlock the door, slide
the manual lever up.
Power Door Locks
On vehicles with power door locks, the switches are
located on the doors.
T:Press the bottom of the switch to lock all the doors
at once. Press the top of the switch to unlock all the
doors at once.
