GMC 2008 Acadia - Manual (Page 184)

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
will sound for several seconds to remind the front
passenger to buckle their safety belt. This would only
occur if the passenger airbag is enabled. See Passenger
Sensing System on page 1-70 for more information.
The passenger safety belt light, located on the
instrument panel, will come on and stay on for
several seconds and then flash for several more.
This chime and light
are repeated if the
passenger remains
unbuckled and the
vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
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 1-61.
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.
