2007 GMC SAVANA 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
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.
CAUTION: (Continued)
CAUTION: (Continued)
We recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbag is off.
If you need to 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.
91

If your vehicle does not have a rear seat that
will accommodate a rear-facing child restraint,
never put a child in a rear-facing child restraint
in the right front passenger seat unless the
passenger airbag status indicator shows off.
Here is why:
{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. Be sure the airbag is off
before using a rear-facing child restraint
in the right front seat position.

CAUTION: (Continued)
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
transported in vehicles with a rear seat
that will accommodate a rear-facing child
restraint, whenever possible.
If you need to 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.
92

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is
present in a rear-facing infant seat.
•The system determines that a small child is
present in a forward-facing child restraint.
•The system determines that a small child is
present in a booster seat.
•A right front passenger takes his/her weight off
of the seat for a period of time.
•The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s frontal airbag, the off indicator
on the instrument panel will light and stay lit to
remind you that the airbag is off.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 following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
(With Passenger Sensing System)in the Index.
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.
If the on indicator is still lit, secure the child in
the child restraint in a rear seat position if one
is available and check with your dealer.
93

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 169for
more on this, including important safety
information.A thick layer of additional material such as a
blanket, or aftermarket equipment such as seat
covers, seat heaters and seat massagers
can affect how well the passenger sensing system
operates. Remove any additional material from
the seat cushion before reinstalling or securing the
child restraint or small occupant. You may want
to consider not using seat covers or other
aftermarket equipment if your vehicle has the
passenger sensing system. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on page 97for
more information about modifications that can
affect how the system operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
of the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors.
If you have any questions about this,
you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer
Assistance are in Step Two of theCustomer
Satisfaction Procedure on page 418.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
the instrument panel, or airbag wiring can
affect the operation of the airbag system.
If you have questions, call Customer
Assistance. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 418.

Section 2 Features and Controls

Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The
transmitter does not send the same signal twice to
the receiver. The receiver will not respond to a
signal that has been sent previously. This prevents
anyone from recording and playing back the
signal from the transmitter.
To resynchronize your transmitter, stand close to
your vehicle and press and hold the lock and
unlock buttons on the transmitter at the same time
for seven seconds. The door locks should cycle
to confirm synchronization. If the locks do not
cycle, see your dealer for service.
Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
four years.
You can tell the battery is weak if the transmitter
won’t work at the normal range in any location.
If you have to get close to your vehicle before the
transmitter works, it’s probably time to change
the battery.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.
106

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 104for 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
Press the bottom side of
the power door lock
switch to lock all
the doors at once. Press
the top side of the
power door lock switch
to unlock all the
doors at once.
When a door is locked, the inside door handle will
not work.
Cargo Door Relocking
This feature protects against having an unsecured
side cargo door. If the side cargo door is open
when the lock button is pressed on the door or the
remote keyless entry transmitter, all doors will
lock and then relock again after the cargo door is
closed. If the cargo door is not closed within
several minutes, the relock will not occur.
