Chevrolet Impala 2007 Impala Owner's Manual page 178

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger's frontal airbag is enabled
(may inflate).
CAUTION:
{
If the on indicator comes on when you
have a rear-facing child restraint installed
in the right front passenger's seat, it means
that the passenger sensing system has not
turned off the passenger's frontal airbag. A
child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's airbag inflates. This is
because the back of the rear-facing child
restraint would be very close to the
inflating airbag. Do not use a rear-facing
child restraint in the right front passenger's
seat if the airbag is turned on.

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 right
front passenger's frontal airbag. See Passenger
Sensing System on page 79 for more on this,
including important safety information.
If, after several seconds, all 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.
CAUTION:
{
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 176.
