Safety Belt Reminder Light; Airbag Readiness Light - GMC Sierra 2005 Owner's Manual

Safety Belt Reminder Light

When the key is turned to RUN or START, a chime will
be provided for several seconds to remind people to
buckle their safety belts. The driver safety belt light will
also be provided and stay on for several seconds,
then it will flash for several more. You should buckle
your seat belt.
See Passenger Sensing System on page 1-74 for more
information.
If the driver's belt is buckled, neither the chime nor the
light will come on.
If your vehicle is not
equipped with the
passenger sensing system,
this chime and light will be
repeated if the driver
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
sensors, the airbag modules, the passenger sensing
system (if equipped), the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, see Airbag System on page 1-63.
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.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
This means the system
is ready.
