Airbag Light (No SRS Urgent Message)
 

On my 2000 S80 T6 the red airbag light comes on slowly after it's started. The "SRS - Airbag Service Urgent" message does not display on the message center (the display does work).

So, when the car is started all of the message lights are off, and just the red airbag light fades on after 30 - 45 seconds.
