Hi I have noticed sometimes try to set adaptive cruise control it does not work. I press the button on steering wheel which switches it on and green light appears but then won’t allow me to set a speed. I’m sure I’m not getting confused with the speed limiter , any idea what I am doing wrong? Secondly I have set my car up so it won’t start unless I place the key fob next to start/stop - will this prevent keyless theft or not?   thanks
