SRS-0025 Passenger air bag, stage 1
 

what does this mean stage 1

Most likely there's a fault in the passenger airbag.
It's triggered by a self-check. If the resistance of the circuit is too low for more than 10 seconds - that code (SRS-0025) is displayed.

It usually means that the igniter is is knackered.

You'll need an avanced code reader to clear this.
Most likely one that's specific to Volvo or a special CANbus code reader.
