GMC 2008 Canyon - Manual (Page 159)

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 sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, see Airbag
System on page 1-60.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. The light
should go out and 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.
{ CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should flash for a few seconds
when you start the engine. If the light does not come on
then, have it fixed immediately. If there is a problem
with the airbag system, an airbag Driver Information
Center (DIC) message may also come on. See DIC
Warnings and Messages on page 3-42 for more
information.
