This helps, but---first off the instructions say to disable the SIR System but will not let me have answer as how to do this----also, cannot get access to more detailed reference's that is offered with the magnifying glass insert
Expert:  Davo replied 8 years ago.
All you need to do is let the car sit for a full minute after the key has been turned off and removed from the ignition.Then disconnect the air bag connector and you will be fine.The magnifying glass will not work for you and I can't do anything about it.If you need it blown up copy the picture and resize it on your end.When you are done just reconnect the air bag connection.
