Pontiac 2006 Vibe Owner's Manual page 142

Your vehicle has a rear seat that will accommodate a
rear-facing child restraint. 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:
{
Even though the passenger sensing system is
designed to turn off the right front passenger's
frontal airbag and seat-mounted side impact
airbag (if equipped) 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
transported in vehicles with a rear seat that
will accommodate a rear-facing child restraint,
whenever possible.
If the word ON is lit on the passenger airbag status
indicator, it means that the right front passenger's frontal
and seat-mounted side impact airbag (if equipped)
are enabled (may inflate).
3-30
CAUTION:
{
If the on indicator comes on when you have a
rear-facing child restraint installed in the right
front passenger's seat, it means that the
passenger sensing system has not turned
off the passenger's frontal airbag and
seat-mounted side impact airbag (if equipped).
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. Do not use a
rear-facing child restraint in the right front
passenger's seat if the airbag is turned on.
