GMC 2007 Sierra - Manual (Page 102)

To turn off the right front passenger’s airbag,
insert your ignition key into the switch, push in, and
move the switch to the off position.
The airbag off light will come on to let you know
that the right front passenger’s airbag is off.
The light will stay on to remind you that the airbag
is off. The right front passenger’s airbag will
remain off until you turn it back on.
{ CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inflate even
though the switch is off.
If your vehicle is a regular cab pickup or
an extended cab pickup and this ever
happens, do not let anyone whom the
national government has identified as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in your vehicle) until you
have your vehicle serviced. See Airbag
Readiness Light on page 247 for
additional information.
