Yes. In addition, the AIH is only activated if the glow plugs are off.

I was honestly not even looking for this, but here's what I came across last night while surfing the net.



With that being said, the parameters I found are here. Must set level to "genius." I'd say it was in the bottom 1/8th, and it took a long time to find.



I figure you could pretty effectively shut off the AIH by setting the the highlighted parameter to say -40.
