Chevrolet Silverado Classic 2007 Owner's Manual page 96

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 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 the right front passenger's
seat) until you have your vehicle serviced.
See Airbag Readiness Light on page 245
for additional information.
