GMC 2007 Sierra - Manual (Page 252)

If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that
the passenger sensing system has turned off
the right front passenger’s airbag. See Passenger
Sensing System on page 103 or Airbag Off
Switch on page 100 for more on this, including
important safety information.
{ CAUTION:
If the right front passenger’s airbag is
turned off for a person who is not in a risk
group identified by the national
government, that person will not have the
extra protection of an airbag. In a crash,
the airbag will not be able to inflate and
help protect the person sitting there.
Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group. See Airbag Off Switch on page 100
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 airbag 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 airbag. See Airbag
Readiness Light on page 247.
