Problems with the occupant classification system
WARNING 
If the 
indicator lamp
illuminates and remains illuminated when the weight of a
typical adult or someone larger than a small individual has been detected on the
passenger seat,
the system then determines the occupant cannot be a child. Do not allow any
occupant to use
the passenger seat until the system has been repaired.
WARNING
If the indicator lamp does
not illuminate or remains out with the weight of a
typical 12-month-old child in a standard child restraint or less, or is
unoccupied, on the frontpassenger
seat, do not transport a child on the front-passenger seat until the system has
been
repaired.
