I would like to get some more info. on the auto height control feature on the lx470.
when the 'low' mode is selected, as per the manual the height goes back to normal after 19mph.
however, should the lx return to low mode once the speed is lower than 19mph again ?
on mine, once the mode goes to normal, it stays in normal even after I park the car... not sure if this is correct behavior.

 

Yes, it is normal. You only need the low mode in certain condition.
