Your vehicle also has a message center that works along
with warning lights and gages. See “Message Center” in
the Index.

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.

The safety belt light will
also come on and stay on
for about 20 seconds, 
then it will flash for 
about 55 seconds.

If the driver’s belt is already buckled, neither the chime
nor the light will come on.

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, the passenger air bag suppression
circuit and the crash sensing and diagnostic module. For
more information on the air bag system, see “Air Bag”
in the Index.

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.
