Passenger Safety Belt Reminder Light; Airbag Readiness Light - GMC Yukon 2007 Owner's Manual

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. 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 93.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
