My cruise control is not much chop at keeping to the set speed when going downhill, with a grade of any more than 2 or 3 degrees.

It will close the throttle most of the way but not all the way, and the car will pick up speed unless I hold the CC wand all the way down. Same as you do to reduce your set speed.

AFAICT holding the wand down does fully close the throttle.

It's bloody annoying having to hold the wand down when going downhill.

So why won't the CC automatically do this (fully close the throttle)?

Is this normal/standard operation for 380 CC?

Does it work the same way for you auto punters, or is it just a quirk of the manual?

Can the CC be adjusted or reset so that it will fully close the throttle?

If so, how?
