depending on the weight applied to the front passenger seat. Front
passenger air bag status (Enabled or Disabled) is indicated by the
front passenger air bag status lamp pictured here
 When the front passenger seat is empty, the passenger air bag status lamp should be
ON (illuminated) which means the passenger air bag is Disabled.
 When the front passenger seat is occupied by an adult, the passenger air bag status
lamp should be OFF (dark) which means the passenger air bag is Enabled.
 When the front passenger seat is occupied by a child, a child restraint, or a small adult,
the passenger air bag status lamp should be ON (illuminated) which means the
passenger air bag is Disabled.
