Cadillac 2008 CTS - Manual (Page 172)

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag status
indicator.
When you start the vehicle, the passenger airbag status
indicator will light ON and OFF, or the symbol for on
and off, for several seconds as a system check. If you
use remote start to start your vehicle from a distance,
if equipped, you may not see the 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 right front passenger’s
frontal and seat-mounted side impact airbags.
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 and seat-mounted side impact
airbag are 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 and
seat-mounted side impact airbag (if equipped).
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.
