Pull the airbag fuse, disconnect the CPA plugs from the driver/passenger side airbags, then remove the airbag as per the manual. Just remember to treat the airbags with utmost respect and care. And yes, the airbag controller module does store energy needed to deploy the airbags for quite some time. However if you disconnect the CPA plug then the system can't send the signal to the airbag even if something did go wrong.
However, if you're the least bit uncomfortable with this, then by all means take the car to someone who is.
