GMC 2007 Acadia Owner's Manual page 86

The passenger sensing system will turn off the
right front passenger's frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver's airbags are not part of the
passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger's
seat. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger's frontal
airbag and seat-mounted side impact airbag
should be enabled (may inflate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the
front seat.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a
rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large
enough, using safety belts.
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 inflates. This is
because the back of the rear-facing child
restraint would be very close to the
inflating airbag.
Even though the passenger sensing
system is designed to turn off the right
front passenger's frontal and
seat-mounted side impact 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 the rear seat,
even if the airbags are off.
