if it has fitted, push the brake(not the one for parking) firmly to the end, then you can hear beeps and see a sign on the dash. My ct is 2015 made and fitted with that funtion,which is quite useful in the UK(Hiiiiiiilllls!) But I got a replaced car from the dealer last year (16Reg), and I was suprised it did not have that function......So maybe Lexus has removed from the car...possiblely...
