so the passenger air bag light keeps coming on when my girlfriends seats in the passenger seat? why does this happen??? should i bring the car in to get it checked out?

 

Mine does that too when my girlfriend leans over or moves. I think it's because they are too light to activate the airbag

 

It happens when my son sits. He weighs about 105.
Is weight a factor?

 

the airbag is weight activated for the passenger side because a person weighing under a certain weight (such as your son at 105 pounds) is most likely either not tall enough or too fragile to handle the impact with an air bag and will be better off in an accident without the air bag. most cars have this now.

 

it is but its supposed to be 60lbs and under it turns off i thought

 

when i put small stuff on my seat it will make the light go on....when i put my math book on my seat goin to school it stays off...i hate math.....being serious now, if you dont sit right in the seat it will go on too.

 

8cd03gro is right.
If you're too light, it wont activate the airbag.

 

I've noticed that. If I'm sitting in the passengers seat and lean over, to say reach something in the back seat, the light comes on. If your girlfriend is leaning towards you or towards the door it may cause the same thing to happen so experiment around next time she is riding with you.

 

Yup it's all about the weight. Most sensors these are rated to activate when is calculates that it has at least 80lbs if weight. When it can't detect that amount but detects that the seat is being used it deactivates the Airbag. It's a safety measure as stated above. My girlfriend causes the same thing both in my mustang and her corolla. i got used to it after a while and we joke about it. You could always go with someone with more cushion for the pushin', lol!

 

Don't worry, if you marry your girlfriend, she'll have no problem keeping the airbag light from coming on.
