The installer said my controller may have a speed limiter function, pressing the On/Off button for a few seconds but I have not tried it as I never found that function useful, next time out I'll give it a try.
Where I find the limiter most useful is when travelling through average speed cameras on road works. If you use cruise control, invariably you have to touch the brakes now and again due to other road users and so are constantly resetting. Whereas with the limiter, you set it on the required maximum speed limit and can be confident that you will not breach the limits and can brake at will or change gear, without touching a reset button. It’s also very handy in 20mph limits which are now becoming prolific, as I find it extremely difficult to keep speed down to that level, without full attention on the speedo rather than the more important road ahead...it feels like walking pace.But the limiter takes care of it.
My Volvo even has the ability to recognise speed limit signs and automatically sets the limit and slows down accordingly.
