Have an '09 G37S with the "All Wheel Steering" option. Was wondering if anyone knows at what speed the "All Wheel Steering" starts working and if it's possible to tell that it is working?

Thanks for the help.

I thought it's supposed to be working at any speed so that it can not only increase the stability at high speed but also decrease turning radius at low speed.

 

well said.it also changes front ratios and turns the rears 1 degree.
