Re: cruise control shutting off
Up hill the CC tries to maintain the chosen speed but if the hill is too steep or you're towing something it will slow down and if the speed drops below a certain % of the chosen speed it will shut off. I think to protect your tranny...
I've experienced this already several times when going uphill with a caravan (1,5 ton) behind it. I've also noticed that when the "ground" of the trailer plug has a bad connection (corrosion) the CC shuts off when you use the left signal to overtake someone on the highway. Why? don't know but it does. Before I changed the plug, it was a great way to know if my lights on the back worked.
