Chevrolet Silverado Classic 2007 Owner's Manual page 250

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 97 or Airbag Off
Switch on page 93 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 93
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 245.
