Cruise control self cancels while towing

[Bennyd04_87]

Hi guys, as the subject line says, today the triton self cancelled cruise control while towing. Both times were while going uphill. Car didn't seem to need to knock back a gear and I was approaching the crest both times. Sitting on 100/110 kph in 5th gear. Car details are 2010 mn triton glxr dual cab 2.5d 5 speed manual. Reasonably stock besides canopy and drawers etc which I wouldn't think would make a difference. Towing a camper trailer around 800-1000kg.
Any ideas? Is it a feature built in to it? Could there be a problem? No codes were thrown. Cheers

Probably need a bit more information but similar problems have been reported before.

Have a look in this thread and also this one.

When playing with the boost on my ml, over lost would kick out the cruise.

I'd say you've reached some threshold parameter and the ecu is just protecting the driveline.

Thanks for the reply guys. I did try a search but couldnt find anything directly related. Both times it happened I was going up hill. I didn't take note of the speed drop as it happened unexpectedly but it may have been that. Thrown no codes. Reset cruise as soon as I cleared the hill and worked fine. Never had it happen before but never really used cruise on it while towing like this. Guess I'll just live with it for now. Cheers

I would say it is a load setting built in somewhere. My 2012 MN does it as well but when it happens I really don't blame it. Same scenario as you. Towing up hill with my camper trailer. I probably had cruise set to 100 in 5th (manual) and the car will drop down to about 85 then cruise kicks off.

Because I know it will happen now, I just drop into 4th and give it some berries. Resume cruise control over the hill.

I imagine Auto's would have extra protection engineered in to avoid overheating.
