5-20 Instruments and Controls
Passenger Safety Belt
Reminder Light
For vehicles equipped with the
passenger safety belt reminder
light, several seconds after the
engine is started, a chime sounds
for several seconds to remind the
front passenger to buckle their
safety belt. The passenger safety
belt light, located on the overhead
console, comes on and stays on for
several seconds, flashes for several
more seconds and then comes on
solid for several more.
This chime and light sequence is
repeated if the passenger remains
unbuckled and the vehicle is in
motion.
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
warning light and chime may turn
on if an object is put on the seat
such as a briefcase, handbag,
grocery bag, laptop or other
electronic device. To turn off the
warning light and or chime, remove
the object from the seat or buckle
the safety belt.
Airbag Readiness Light
The system checks the airbag's
electrical system for possible
malfunctions. If the light stays
on it indicates there is an electrical
problem. The system check
includes the airbag sensor, the
pretensioners, the airbag modules,
the wiring, and the crash sensing
and diagnostic module. For more
information on the airbag system,
see Airbag System on page 3‑29.
The airbag readiness light comes
on solid for a few seconds when the
engine is started. If the light does
not come on then, have it fixed
immediately.
