All purpose mode drops to low when cruise is set

[ebarke]

Anyone else notice this, but if I turn on cruise control in all purpose mode, after a certain amount of time, the car will drop to low ride height. At first I thought I was having suspension issues, but it seems to happen regularly only if I have cruise set. As soon as the speed drops to < 40 mph or so, then it will raise back to standard height. This is with auto setting on all purpose.

If you have the ride height set to "Auto," it is supposed to do this. Has nothing to do with cruise. It's sustained speed over 45mph.

Continuous speeds at lower height reduces drag. So this is a feature.

Efficiency feature, yes, love it on the highway. Why I get 2.4-2.6 m/kw going 70 mph in my r1T.

Feature? Yes... HATE IT. Makes the truck bounce around like one of those old Lincoln's with the blown air suspension. It also aggravates my back injury. I cant imagine its good for the suspension stops either.

Turn off Auto, and just run is Standard Mode, with Kneel is what I do.

You have the ride height set to Auto mode. It'll drop to low when you're sustaining speeds above 50 mph or so, regardless of cruise control in my experience. If you don't want it to drop ride height at highway speeds, just turn off Auto mode.

I used to feel the same way. Have you tried it lately? After a software update at one point i looked down and noticed the “A” and realized i had been in auto and wasn’t experiencing the bouncing around at stoplights and such that i was getting on earlier software iterations. I now roll in auto with no complaints.

Been on the same software since I bought the truck. When I did a hard reset a week ago, it went back to auto, and I noticed it within a couple miles. Back to standard now.

Looks like you're driving an R1T and TollKeeper has an R1S. The R1T is generally understood to have better ride quality than the R1S, so it's possible you're both right!

I now keep mine at standard height. Lowering your suspension also affect your tire life. You get better suspension and tire life by keeping at standard height. It may affect your range but, not by much. The R1S won't spend significant energy raising and lowering the vehicle while driving. That was also the advice from my service technician.

I love that I can set this and forget it, and get the best efficiency. I don't notice any difference in ride quality in the R1T.
