Hi how do i switch off the front passenger airbag as i need to put a children's car seat? thanks

You don't have that smart stuff for weight. You can't turn it off. If you don't think they should be in front, because of age or height. Put them in back. I haven't seen a van yet that had this option.

The passenger airbag is activated by a weight switch in the seat. It requires enough weight to activate in order to protect younger children when seated there. The is no external switch to turn it on.

on some cars there is a switch that you can turn the system off for the passenger side. however children should be put in the rear seat until old enough to not require a child seat.

I doesn't look like you can disable it. The manual says all children should be in the back seat and never in a rear facing child seat in the front seat. manual is here : https://duckduckgo.com/l/?kh=-1&uddg=http%3A%2F%2Fwww.dodge.com%2Fdownload%2Fpdf%2Fmanuals%2F2005_PL_Neon.pdf

You can check with the dealer to verify, but as far as I know the only time you can turn off a passenger airbag is in a truck.

If it says "airbag" on the stering wheel AND on the dash in front of the passenger,then it has a passengers side airbag.
Children are much safer in the back seat in the event of a collision.

The airbag system in this car is second generation smart airbags, there is no switch, if the weight in the passenger seat is not at least 50 pounds (there is a sensor in the seat cushion) the airbag is switched off to the paassenger seat, but small children should always be in a approved child seat in the back seat anyway.

lol sometimes check the car manual, its a security device for when children sits in front, when the weight is not high enough on the passenger seat (i.e. child) it turns off the airbag so the kid wouldnt be hurt by the airbag in case of an accident

Well, for one you not suppose to put a baby seat in the front of the car. But anyways with an older airbag control system like that you cannot just disable one airbag, if you unplug the passenger side airbag then in an accident neither airbags will deploy.

Children in car seats should never be put in the front seat.  In fact children under the age of 13 should never be in the front seat.  Their bodies are not large enough or strong enough to sustain the impact of a crash or an airbag.  For your baby's safety and your peace of mind it'd be best for you to keep your baby in the rear seat and get a mirror for the back seat to see what's going on.
