INSTRUMENTS AND CONTROLS 121
Passenger Seat Belt Reminder
Light
There is a passenger seat belt
reminder light near the passenger
airbag status indicator. SeePassenger
Sensing System 071.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their seat
belt. Then the light stays on solid
until the belt is buckled. This cycle
continues several times if the
passenger remains or becomes
unbuckled while the vehicle is moving.
If the passenger seat belt is buckled,
neither the chime nor the light
comes on.
The front passenger seat belt reminder
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 reminder light and/or
chime, remove the object from the
seat or buckle the seat belt.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the passenger
sensing system, the pretensioners, the
airbag modules, the wiring, and the
crash sensing and diagnostic module.
For more information on the airbag
system, see
Airbag System 065.
The airbag readiness light comes on
for several seconds when the vehicle is
started. If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in the
vehicle might not inflate in a crash,
or they could even inflate without a
crash. To help avoid injury, have
the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 71. The overhead console has a
passenger airbag status indicator.

122 INSTRUMENTS AND CONTROLS
United States
Canada
When the vehicle is started, the
passenger airbag status indicator will
light ON and OFF, or the symbol for
on and off, for several seconds as a
system check. Then, after several more
seconds, the status indicator will light
either ON or OFF, or either the on or
off symbol, to let you know the status
of the front outboard passenger
frontal airbag and knee airbag. If the word ON or the on symbol is lit
on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag and
knee airbag are allowed to inflate.
If the word OFF or the off symbol is lit
on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag and
knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See your
dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
(Continued)
Warning (Continued)
the vehicle serviced right away. See
Airbag Readiness Light0121 for
more information, including
important safety information.
Charging System Light
On some vehicles the charging system
light comes on briefly when the
ignition is turned on, but the engine is
not running, as a check to show the
light is working. It should go out when
the engine is started. For vehicles with
a reconfigurable cluster, this light may
not come on when the ignition is
turned on.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.
