Removing the passenger airbag is easy and safe if done correctly. The previous instructions are correct, but you also need to disconnect the battery before unplugging the red connector in the footwell.

The airbag can be a bit fidgety to remove; it's in there quite tightly. But only the single 10mm bolt holds it in place. The two electrical connectors to the back of the airbag can be pulled off by hand. Be sure to set the airbag face up.

The vacuum valve is easily accessed once the airbag is removed. I doubt you could access it from below.
