In my Ignis I have only one speed limiter - my right foot. I don't know about another speed limiter.
Or do you mean the speed limiter when going downhill?

 

No. Active Speed Limit Assist. Provided in most new cars. Most people try to turn it off!

 

I’m not sure exactly what you mean by “ Speed Limit Assist”. If it’s the car “knowing” what the speed limit is on any particular road I’d say my 2023 “top of the range” (lol) doesn’t have it. If it’s cruise control then mine does have it (never used it though, big scaredy-cat here). If it’s cruise control I’ll try and fish out the pages from the manual that tell you how to do it. M

 

If you know how to drive, then just keep doing the same and don't expect miracles, just turn on the unsolicited help experience and then you decide if it works for you.
