GMC Chevrolet SSR 2003 Owner's Manual page 57

The airbag off light, located on the roof panel above
the rearview mirror, will come on and stay on to let you
know that the passenger's frontal airbag is off. See
Airbag Off Light on page 3-26. The passenger's frontal
airbag will remain off until you turn it back on again.
CAUTION:
{
If the airbag readiness light ever comes on
when you have turned off the passenger's
frontal airbag, it means that something may be
wrong with the airbag system. The passenger's
frontal 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 passenger's position (for
example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced.
United States
To turn the passenger's frontal airbag on again, insert
your ignition key into the switch, push in, and move
the switch to the on position.
