2008 GMC SAVANA PASSENGER ECU

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag if the system detects a rear-facing
child restraint, no system is fail-safe, and
no one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We recommend
that rear-facing child restraints be secured
in a rear seat, even if the airbag is off.
If you secure a forward-facing child restraint
in the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.
SeePassenger Sensing System on page 1-69
for additional information.If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not be
transported in your vehicle, even if the airbag is off.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children (LATCH)
on page 1-39for how to install your child restraint using
LATCH. If you secure a child restraint using a safety
belt and it uses a top tether, seeLower Anchors
and Tethers for Children (LATCH) on page 1-39
for top tether anchor locations.
Do not secure a child seat in a position without a
top tether anchor if a national or local law requires
that the top tether be anchored, or if the instructions
that come with the child restraint say that the top strap
must be anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.

You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator in the passenger airbag status indicator
should light and stay lit when you start the vehicle.
SeePassenger Airbag Status Indicator on
page 3-30.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Push the latch plate into the buckle until it clicks.
Make sure the release button is positioned so
you would be able to unbuckle the safety belt
quickly if necessary.
1-50

7. If your vehicle does not have a rear seat and your
child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding the
use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-39for
more information.
8. Push and pull the child restraint in different
directions to be sure it is secure.
If the airbag is off, the off indicator in the passenger
airbag status indicator will come on and stay on when
the vehicle is started.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the
child restraint into the seat cushion. If this happens,
slightly recline the vehicle’s seatback and adjust the
seat cushion if possible. Also make sure the child
restraint is not trapped under the vehicle head
restraint. If this happens, adjust the head restraint.
Remove any additional material from the seat such
as blankets, cushions, seat covers, seat heaters or
seat massagers before reinstalling or securing the
child restraint.If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle
and check with your dealer/retailer. If no rear seat is
available, do not install a child restraint in this vehicle
and check with your dealer/retailer.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way. If the top
tether is attached to a top tether anchor, disconnect it.
Securing a Child Restraint in
the Right Front Seat Position
(With Airbag Off Switch)
Your vehicle has airbags. A rear seat is a safer place
to secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-38.
There is a switch on the instrument panel that you
can use to turn off the right front passenger’s frontal
airbag. SeeAirbag Off Switch on page 1-66for more
on this, including important safety information.
A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys.

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the airbag off switch is designed
to turn off the right front passenger’s frontal
airbag, no system is fail-safe, and no one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it
is turned off. We recommend that rear-facing
child restraints be secured in the rear seat,
even if the airbag is off.
If you secure a forward-facing child restraint
in the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front passenger’s
seat) until you have your vehicle serviced.
SeeAirbag Off Switch on page 1-66and
Airbag Readiness Light on page 3-27for more
on this, including important safety information.
If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not be
transported in your vehicle, even if the airbag is off.

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children (LATCH)
on page 1-39for how to install your child restraint using
LATCH. If you secure a child restraint using a safety
belt and it uses a top tether, seeLower Anchors
and Tethers for Children (LATCH) on page 1-39for
top tether anchor locations.
Do not secure a child seat in a position without a
top tether anchor if a national or local law requires
that the top tether be anchored, or if the instructions
that come with the child restraint say that the top
strap must be anchored.
In Canada, the law requires that forward-facing
child restraints have a top tether, and that the
tether be attached.You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
If you have no other choice but to install a
rear-facing child restraint in this seat, make
sure the airbag is off once the child restraint
has been installed.
When the airbag off switch has turned off the
right front passenger’s frontal airbag, the off
indicator in the airbag off light should light and
stay lit when you start the vehicle. SeeAirbag
Off Light on page 3-28.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
1-54

6. 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. If you are using a
forward-facing child restraint, you may find it
helpful to use your knee to push down on the
child restraint as you tighten the belt.7. If your vehicle does not have a rear seat and your
child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding
the use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-39for
more information.
8. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way. If the top
tether is attached to a top tether anchor, disconnect it.
If you had turned the airbag off with the switch,
remember to be sure to use the airbag off switch
to turn on the right front passenger’s airbag when
you remove the child restraint from the vehicle unless
the person who will be sitting there is a member of
a passenger airbag risk group. SeeAirbag Off Switch
on page 1-66.
1-56

{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.
1-59

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.
