The air bag warning light on my Kia Sportage XS year 2006 is now permanently on.

Looking at the internet forums this seems to be quite a common issue and not just with the Sportage.

Kia seem to decline the need for a recall.

Does anybody have any suggestions as to what to check/re-set before I book it in to my local Kia dealer for what might turn out to be an expensive repair?

Thanks.

Frank Hayward.
