That one should only illuminate when weight is preset, but the seatbelt is not latched.

i have modeified my initial question to be more clear. I am not concerned about the passanger seat belt light. so i correted the error. excluding the passanger seat belt light there are 3 other lights:

1) airbag, 2) on and 3) off - for instance when passanger is sitting 2 lights are on : Airbag and On which makes it 'airbag on' etc. But the airbag light (Light number 1) is always on whether passanger is sitting or no. Thats the part thats confusing me - shld thatlight always stay on.
