GMC 2006 Sierra - Manual (Page 213)

Airbag Readiness Light
There is an airbag readiness light on the instrument panel
cluster, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the airbag sensors, the airbag
modules, the passenger sensing system (if equipped),
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, see Airbag
System on page 1-70.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds. This
means the system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your airbag
system may not work properly. Have your vehicle
serviced right away.
Airbag Off Light
If your vehicle has an airbag off switch, it also has an
airbag off light. See Airbag Off Switch on page 1-78 for
more on this, including important safety information.
