Charging System Light; Malfunction Indicator Lamp; (Check Engine Light) - Cadillac CT6 2017 Owner's Manual

When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If 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 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

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
