Bf Cruise Control Dropping Out Of Set

[Paradoxx]

Has your service department mentioned anything about it?

Hi XXXR6T,

I have not taken it in to check yet. I do mostly city driving with cruise control totally off, so I'll mention it when I take the car next in for something critically wrong or the next scheduled service, whichever comes first.

if the car can not easily maintain speed while on CC it will disengage as a safety feature (something may be wrong). ive never had it happen in a BA though because the torque normally pulls the car up any hill without fuss.

on a down hill though I wanst a wear of the CC cutting off for any reason. on a recent long trip my 110km/h CC set ended up at over 135km/h on a long downhill section. it only cut the CC when I hit the brakes after seeing the speed I was going

Its probably the the car rolling faster down the hill. Just push the gear into manual mode and try 5th gear if you want it to stay at the speed rolling down the hill, and reactivate cruise (I'd use the Set - (minus)), try a lower gear again if your still accelerating. pretty annoying though.

All cars with cruise control do this - except for those __REALLY__ expensive ones which can use the break to maintain speed.

Unless you have the foot on the brake, the 6sp auto will not kick down a gear to slow you down. Either way though, that would de-activate the cruise control because you've got your foot on the break.

Hi mattyc,

Sounds like you know what you are talking about. This sort of lines up with some of what I read earlier, that the car going faster than it could regulate the speed (and not being able to use the brake - though I thought it did) drops out of cruise control set as a safety precaution. Problem with this is that there is no warning chime to make the driver check the dash alarms nor would a driver normally have their foot on any of the foot pedals at the time the cruise control set goes OFF which is a bit of a safety hazard (I.e. it actually creates a safety hazard ).

Wonder if Ford is taking note of this thread?

Exactly - a chime would be usefull even slightly before it drops out.

Mine does if the cruise control is on ...

I don't think cruise control ever applies the brakes   It will however deactivate if the vehicle goes over or under speed.

Correct - BA/BF cruise control systems use 'Engine braking' rather than using the brakes to slow the car down. Not really the best of systems out there, due to the fact that any (decent) decline WILL result in the car gaining speed. The Ford engineers have worked on that theory, that when driving a deep decline/incline ... you should not be using cruise control in the first place.

Exactly - a chime would be usefull even slightly before it drops out.

Would be good, But these cars have too many chimes as it is. Seems each day I figure out a new chime on this bloody car!

Fair point....would turn the bloody thing into an orchestra
