Hi Ian – I saw you had posted last night – but couldn’t see actual text until this morning.
The speed limiter is the same button as for the smart cruise control, just press it twice or hold it in longer. The display in front of you changes from cruise to speed limit then set the speed you want – if you exceed it it should Bing at you as long as you are gentle with the acceleration. If you press hard you will easily over ride it in emergency situations where acceleration is more important than braking – you will still creep slightly over before it bongs at you – sometimes I find setting smart cruise to eg 20 mph works better – it is not meant for low speed so prob isn’t recommended, but I like to use it – it is so easy to exceed a 20 mph speed limit – also useful on A and motorways when a 50 mph limit is set for road works – I hope this helps ?
