Hi
Just found this on the Lexus manual, it appears your car has a foreign ECU in it as the feature you are missing is fitted for the UK market but not for some other markets, if your car has a full Lexus history I think I would go back to Lexus and ask for their comments because as can be seen it should have this feature... or is your car an import, if it is it should say something like "Used and/or registered in a foreign country prior to the UK" on the V5 registration document.
Good Luck, let us know what happens.

Hi Cheers for that.I have been doing some research on this & this is what I have found.In August 2004 they brought out new features which included Pre Crash Safety System only avaliable for Europe models ONLY & Dynamic Radar Cruise Control System which my car has.As for customising parameters on the full closure side of things.I believe this is not possible,all you can do is door/key-linked p/w up default is On contents of this setting is Function that raises all windows & roof with ignition switched OFF,key is used to hold driver door key cylinder to lock position for more than 1.5 seconds.This setting can be turned on or off in diagnostic menu & as for opening the windows & roof door/key-linked p/w down default is On contents of this setting is Function that lowers all windows & roof with ignition switched OFF,key is used to hold driver door key cylinder to unlock position for more than 1.5 seconds.Keyfob unlock button held will also open roof & sunroof.Nothing available for keyfob lock button when held.Not yet anyway.It will though watch this space
