4-wheel steering (2008 Infiniti M45 Sport)

[obleft]

At what speed does the 4-wheel steering (rear wheels) take effect? '08 M45 Sport

[RipplingHurst]

According to the user manual (p.5.52), it does nothing at low speeds, but doesn't say at which speed. At higher speeds, depending also on the steering wheel angle, it turns first to the oposite direction, then to the same direction as the front wheels.

I just bought my 06 Sport (over a G35 coupe w/o this feature) pretty much because of this very feature, and I'm still testing it. Just waiting for some warmer weather to get some conclusions with my current summer tyres.
