Dynamic Radar Cruise Control (ACC) on RX450h 2012 onwards

[DC369]

Hi

I currently own a 2009 Lexus RX450h SE-L Premier which includes Adaptive/Dynamic (Radar) Cruise Control. I have been looking at the newer (2012 onwards) versions and none of them seem to have this feature. The owners manual I downloaded suggests that this is an option now, and indicated by a fourth button at the bottom of the right hand group of controls on the steering wheel (below the voice control button?).

Can anyone confirm this, or is there another way to check if this feature is installed?

Was this a very expensive option? (as I can't see any cars on eBay or autotrader showing that button or mentioning ACC).

I assume that this isn't available (or is very costly) as a retro-upgrade?

Thanks.

Yep. That's the button. Super rare option - along with the pano roof on sport models I must have only seen either 2 or 3 times.

Retro upgrade i'm presuming would be many thousands - parts + coding/calibration might make it not really a viable option.
