Airbag Readiness Light - GMC 2008 Envoy Denali Owner's Manual

This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver's belt
is already buckled, neither the chime nor the light will
come on.
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 1-61 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.
If the passenger's safety belt is buckled, neither the
chime nor the light will come on.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.

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 1-53.
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.
