2008 GMC Savana Owner ManualM

The passenger’s side pin has a black cap with a
white “R” marked on it.
On a four passenger seat, each half of the seat has
a set of pins. The driver’s side has a set marked “L”,
and the passenger’s side has a set marked “R”.
If the vehicle has floor mats, the pins will be located
under a flap that has been cut into the mat.3. Pull the pin handle up to disengage the pin from
the retaining clip, then pull the pin out.
4. Repeat this procedure for the other pins.
5. Pull the seat rearward about 2 inches (5 cm)
and then lift the seat from the floor rails.
6. Remove the seat from the vehicle.
7. For the first row
rear seat, stow the
safety belt latch
by attaching the clip
on the safety belt
latch to the trim just
inside the side door.
For the remaining rear seats, stow the safety
belt latch plate on the clip at the window trim. Three Passenger Seat Shown

A booster seat (C-D) is a child restraint designed to
improve the fit of the vehicle’s safety belt system.
A booster seat can also help a child to see out
the window.
Securing an Add-On Child Restraint
in the Vehicle
{CAUTION:
A child can be seriously injured or killed in
a crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also the instructions
in this manual.
1-36

{CAUTION:
Airbags inate with great force, faster than
the blink of an eye. Anyone who is up against,
or very close to, any airbag when it inates
can be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts
help keep you in position before and during
a crash. Always wear your safety belt, even
with airbags. The driver should sit as far back
as possible while still maintaining control
of the vehicle.
Occupants should not lean on or sleep
against the door or side windows in seating
positions with roof-rail airbags.
{CAUTION:
Airbags plus lap-shoulder belts offer the
best protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and infants
need the protection that a child restraint
system can provide. Always secure children
properly in your vehicle. To read how, see
Older Children on page 1-29orInfants and
Young Children on page 1-32.
There is an airbag
readiness light on
the instrument panel,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-27
for more information.

If your vehicle is a cargo or passenger van with
a sliding door and it has a roof-rail airbag for the
driver and right front passenger position, the roof-rail
airbags are in the ceiling above the side window.If your vehicle has roof-rail airbags for the driver,
right front passenger, passengers behind the driver
and right front passenger, and the third row outboard
passengers, the roof-rail airbags are in the ceiling
above the side windows. On the driver’s side of the
vehicle, there is one single roof-rail airbag for either
vehicles with a hinged door or a sliding door. Driver Side shown, Passenger Side similar

1-61

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 inate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inating 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 inating roof-rail airbag will be blocked.
When Should an Airbag Inate?
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

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing
the bag to break out of the cover and deploy. The
inflator, the airbag, and related hardware are all part
of the airbag module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with roof-rail airbags, there are airbag modules in the
ceiling of the vehicle, near the side windows for the first,
second, and third rows (if equipped). SeeWhere Are
the Airbags? on page 1-60for more information.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants in the
outboard seating positions in the first, second, and
third rows, if equipped. The rollover capable roof-rail
airbags are designed to help reduce the risk of full
or partial ejection in rollover events, although no system
can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-62for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an
Airbag Inates?
After the frontal airbags inflate, they quickly deflate,
so quickly that some people may not even realize
an airbag inflated. Roof-rail airbags may still be at
least partially inflated for some time after they deploy.
Some components of the airbag module may be hot for
several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-64.
1-64

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 inates, 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 inates, 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.
