Buick 2007 Rainier Owner's Manual page 184

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 the unless passenger airbag
status indicator shows off. Never put a rear facing
child restraint in the right front passenger seat
unless the airbag is off. Here is why:
CAUTION:
{
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. 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 OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger
sensing system has turned off the right front
passenger's frontal airbag. See Passenger Sensing
System on page 78 for more on this, including
important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
CAUTION:
{
If the off indicator and the airbag
readiness light ever come on together,
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 seat
may not have the protection of the frontal
airbag. See Airbag Readiness Light on
page 181.
