On current Chrysler vehicles (since at least 1997) the auto tranny will
downshift to a lower gear if speed increases 2-3MPH above the setpoint of
the Cruise Control. RPM's jump way up when in a downhill "run-away"
situation. That tends to keep downhill speed in check fairly well.
You can't set it to 40 or whatever round town then drive 'normally' in
traffic and rely on it to stop you exceeding the limit.
You'll be doing 40 all the time - could get exciting!
A limiter will stop you doiing over the limit even if you press your foot
down (to a point).
Cruise keeps you at a set speed regardless of required throttle changes. Two
totally different things but closely related in their sensing/control
If one would be better served by reading their owners manual to discover how
CC actually works, rather than listing to all the disinformation that is
being posted on the subject in this NG.

It was on some Renault (Megane?) I had the other day. Choice of cruise control
- which almost does the same thing - and a limiter, which allows you to drive
about normally but not above the set speed.
Be warned, though, cruise control on my other car does not alter the speed you
set, but when going downhill, it only gives engine braking. So you can set 30
mph as a cruise speed, and the fancy computer will only be able to keep to this
speed if, in the gear you have selected, engine braking can keep it.
