Passenger Safety Belt Reminder Light; Airbag Readiness Light - Chevrolet 2007 TrailBlazer Owner's Manua

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, 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 80 for more information. The
passenger safety belt light will also come on
and stay on for several seconds, then it will
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
will be 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, 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 wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, see Airbag System on page 69.
Then the light should go out. This means the
system is ready.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
