2007 GMC CANYON ECU

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
and the airbag is 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.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
CAUTION: (Continued)
CAUTION: (Continued)
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
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.

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’s frontal airbag has been
turned off by the passenger sensing system, 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
on page 71.
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 in the vehicle if
one is available and check with your dealer.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides 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 the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure
on page 456.
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,
instrument panel, ceiling headliner, ceiling
and pillar garnish trim, roof-mounted airbag
modules, or airbag wiring can affect the
operation of the airbag system. If you
have questions, call Customer Assistance.

Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in

Procedure on page 456.

it is programmed from the factory to lock all doors
automatically when the shift lever is moved out
of PARK (P). All the doors will unlock when
the shift lever is moved back into PARK (P).
If your vehicle has a manual transmission, it is
programmed from the factory to lock all the
doors when the vehicle speed is greater than
15 mph (24 km/h). The doors will unlock when
the key is removed from the ignition.
To change the automatic door lock and unlock
settings, see “Automatic Door Locks” under
DIC Controls and Displays on page 194.
