Does anyone know what the algorithm used for the 'time to take a rest break' warning is that appears on the dash? I just did a 2800 km road trip and received this warning twice. I have seen it several other times when just driving around town here. I can't figure out what causes it to appear - it seems to happen for no apparent reason. I also reset the trip 1 and 2 meters after filling with gas which resets the timer but that doesn't seem to influence the warning. On this last trip, I drove for almost 5 hours, stopped and refueled (reset the trip 1 meter) and then had lunch so 1 hour rest in total. I got back on the road and 1 hour later I got the message 'time for a rest break'?

Good question..My wife gets it a lot, I always freak. She blames it on the car going over the lines when she has the lane departure thing on and the lines aren't clear..
I think she's swerving too much :grin

I don't swerve or cross the lines except when I intentionally want to change lanes and then I always use the turn signal so that definitely is not what triggers the message.

I believe it reads your eye movement like glancin down or dozing off
first turn the lane change off, easy to hit the button accidentally
second..DONT TEXT AND DRIVE
third.. turn the lane change warning on at all times

I turned mine off, it was always going off, I don't know how the one in the Ford works, but i know some of them are based on seat posture.

No if the steering senses a lot of corrections and the cameras pickup a lot of movement near the stripes you get the warning.. The vehicle will also sense if you don't have your hands on the wheel.

I'm not sure that we are talking about the same thing. It seems like you are referring to the lane departure warning system that causes the steering wheel to vibrate when you cross the lines. I am talking about the warning that comes up on the left display with the symbol of a coffee cup and the warning to take a rest break. I thought it would be based on the trip1/2 timers but I can reset the timers, drive only a couple of hours and I will get the warning message and I know that I am not weaving all over the place or taking my hands off the wheel. There seems to be no rhyme or reason as to why the message displays.

I think the rest warning IS tied to the lane departure warning system. Have you noticed how often the lane departure system shows a yellow line? i.e., you have drifted into a lane marking, but the car corrects itself. The steering wheel does not shake when that happens - it only shakes when you keep crossing a land marking and the indicator turns from yellow to red.

But I believe that if the lane departure indicator is only turning yellow and successfully guiding the car back into your lane with some degree of frequency, then you will see the rest break suggestion. It assumes you are drowsy if the car is wandering that much.

I know for a fact that I do not venture outside of my lane when driving unless I do it intentionally. I'm not sure what yellow line you are referring to. There is always a yellow line on each side of the car on the right hand display provided that the sensors can detect the lane markings on the road which is not always the case when the markings have faded a lot. I also always use my signals when changing lanes so that can't be a factor either. The steering always shakes as soon as the car begins to cross into a marking without using the signal and at the same time then corrects itself. I've never noticed any kind of indicator turning from yellow to red.

The lane markings in the right instrument cluster are what I am referring to. They are green when you are in your lane, yellow when you drift either left or right to the edge of your lane or red when cross into another lane. The wheel only shakes when you reach the red zone (you have continued to cross into another lane even though the lane indicator is showing yellow). And yes, the use of turn signal temporarily turns off the lane departure system.

If you are, as you said above, always seeing a yellow line in the display and not a green line, then either sonething is wrong or you are riding on the edge of your lane; either one I imagine could trigger the rest alert.

When I am driving and especially when changing lanes , I am not usually looking at the dash :) Also I am colour blind so depending on the ambient lighting, etc., green and yellow look very much the same to me so perhaps the markings in the dash are always green rather than yellow....I just know that I drive in the middle of my lane and very, very rarely ever come close to the lane markings unless I intentionally do so. I still don't think that this is related to the rest warnings.

Countryguy.......I know what you are talking about. When I got my MKC, I had the same thing. I disabled it in the settings. I don't recall just where in the settings, but the next time I am in the car I will try to find them for you. Trust me.....It is in the settings.

Oh I know how to disable it in the settings....I just want to know the parameters for how the thing works! Working in software design, programming, etc. for 35 years...the logic in me just wants to know the reasoning behind everything :)

The vehicle senses steering input from the driver so a pattern that could be attributed to drowsy driving may set it off. I'm sure there is some white paper out there like so many steering corrections per mile may trigger a warning or erratic input etc.

When it went off, were you on grooved highway? Mine went off when I took delivery, and was making the 180-mi trip home. It was because the highway was grooved, and these lousy Latitude tires tramline worse than any other I've driven on. The grooved highway was causing the MKC to sway back and forth so bad, that it thought I needed a rest.

It has gone off many times and never when I was on a grooved highway....just driving down the road on smooth pavement. And sometimes I had only been driving a few minutes.
