IAS = Integrated Active Steering

Meaning the rear wheels turn up to 3deg to make the turning circle smaller. Works incredibly well and makes the car turn a good 2 feet less than without it!

It's only available on non x-drive models though. I don't think you have it since you are running 315 in the back and I'm sure the tires would start to rub against the wheel wells at that point!?!
