Safety Belt Reminder Light - GMC 2001 Denali Owner's Manual

When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a message center that works along
with the warning lights and gages. See "Message
Center" in the Index.

Safety Belt Reminder Light

When the key is turned to RUN or START, a chime
will come on for about six seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
If the driver's belt is already buckled, neither the chime
nor the light will come on.

The safety belt light will
also come on and stay
on for about 20 seconds,
then it will flash for

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see "Air Bag" in the Index.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
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. Then the light
should go out. This means
the system is ready.
