Ye Phil, if you see radar ready when you engage cruise, top spec had keyless entry and go, soft closing doors, rear screen and side window blinds, a fridge, and power seats in the rear. William
Yes. Has everything but don't recall anything coming up on dash apart from cruise.
hi
phil only the facelift 430s came ACC Adaptive Cruise Control or Radar Cruise Control - in tends to be limited to 55 and 06 plate cars.
The easiest way to tell is to look at the grill - the ones which have have a clear rectangle around the logo like this overpriced example at Lexus coventry:
http://www.raccars.co.uk/used-lexus/ls/details-12279809/lexus-ls-430-4-3-v8-4dr-auto-acc-pcs
if you then lift the bonnet you will see a square box behind the grill which contains the electrical gubbins for the ACC
then as someone mentioned above when you press cruise a picture of a car with road markings comes up and says cruise ready.
hope this helps
