When the vehicle is started, the
passenger airbag status indicator
will light the words ON and OFF for
several seconds as a system check.
If you are using remote start,
if equipped, to start the vehicle from
a distance you may not see the
system check. Then, after several
more seconds, the status indicator
will light either the word ON or OFF
to let you know the status of the
right front passenger frontal airbag.
If the word ON is lit on the
passenger airbag status indicator, it
means that the right front passenger
frontal airbag is enabled (may
inflate).
If the word OFF is lit on the airbag
status indicator, it means that the
passenger sensing system has
turned off the right front passenger
frontal 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/retailer for service.
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 the vehicle serviced right
away. See
for more
information, including important
safety information.
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.
The light turns off when the engine
is started. If it does not, have
the vehicle serviced by your
dealer/retailer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer/retailer. Driving while this
light is on could drain the battery.
This light and a Transport On
message display when the vehicle
is in Transport Mode. For more
