Some cars can have the passenger airbag de-activated for purposes of using a child seat in the front - but I do not believe this applies to Saabs.
When I bought my 98 CSE from St George Saab (Bristol) the Sales Director gave me just one piece of duff advice: When asked if the passenger airbag could be deactivated he told me, 'Yes', and that their workshop could do it via by adjusting the car computor!
According to the Service Manager of a Saab Maindealers, diactivating passenger airbag cannot be done, and that both the passenger and drivers airbags are operated by the same system. Meddling with one could affect the other!
>>the passanger airbag will have no effect on passenger survivability if the passanger is secured by a three point belt ..
Apart from 'low impact' accidents, I must seriously disagree with this statement. Apart from the serious danger of injuring a child in a car seat, passenger airbags have proven to save lives in serious accidents on many occassions!
3 Point seatbelts are 'designed' to unravel in a serious impact, so that they do not cut the person up - and to 'absorb' some of the force! A seat belt will not stop drivers hitting the steering wheel (which often causes the worste head injuries in a car accidents) or stop front seat passengers hitting the window or dashboard. Airbags do, and they spread heavy the forces across a much wider area of a persons body, which significantly reduces serious damage.
