Why does your airbag warning light stay on all time on your 2002 Jeep Liberty?

The airbag warning light is indicating the airbag(s) may NOT be functionig. As it says in the manual, "Ignoring the AIRBAG warning light in your instrument panel could mean you won't have the airbags to protect you, (or your passangers), in a collision...have the airbag system checked RIGHT AWAY." Always wear your seatbelt!!! On my 2004 there is a light on the passanger grab bar that indicates the passanger airbag is off. This happens when a child is in the seat to protect the child from the sudden force of an airbag. It can also be fooled by a package or briefcase on the seat. This is normal. When an adult sits on the passanger side the light should go off. This information was an addition to the 2004 manual.
