No downsides. You just go back to‘ Build Mode’ and when you click on it again, you’ll leave build mode. The suspension reverts back to normal operation.
You can do the same if you have an EAS problem and need to manually raise the vehicle to get back home.

Actually you can self-level the vehicle. I don't have the time to UL pics right now, but I just used this feature last night on (albeit on my old L322 travel vehicle).
-You first need to disable the air suspension by going into build mode into 'Service Test > CHCM>Build Mode' (CHCM = Chassis Control Module - in older vehicles the RLM (Ride Level Module) or even older simply EAS and Transport Mode).
- Then you choose the 'Test Valves' function in the same menu. You have the option of leaving either front or rear or all 4 corners linked/unlinked. If you go with all 4 unlinked you can compensate for some pretty hefty holes or angles and still get the car level. I use a level app on my phone on my center console lid which is parallel to my RTT in both axes.
We are camped out on a beach in Albania (as I write) and last night was probably the most extreme angle I have ever used this function on: the LR was on the bump stop and the RF completely extended. Funny that this topic should come up now :-p
We just spent a week off-roading and camping on the beaches and in the mountains of Albania. Beautiful country and unbelievably friendly people. First time here for me and I am coming back!

Superb and unheralded feature.

Im a bit wary to start clicking on things.
Manual calibration gives the last image. I’m not sure what I’m looking at here. Parked on the flat I thought these values would be more similar.

While you can adjust the suspensions height by adding more or less air to each corner, there’s nothing to actually lift a wheel in the suspension. The air springs only press down so the only way possible to do something like this would be to raise the two corners adjacent to the wheel you want to lift and lower the corner diagonally across from the wheel you want to lift completely. If you then had more weight above the lowered corner than the corner you want to lift, and the suspension had more travel at the corner you lowered then you might get one wheel slightly up in the air . Not seeing it as a practical function though… :-p

There are more functions that would be really useful for serious off-roading or camping including a one button self-leveling feature. And we might be working on something that, if I told you about, I’d have to kill you 😜
