As some of you may have discovered, that even if you set the opening height of the trunk, it will almost always open to its default height when opened in a car park where clearance is low. Problem is that the default height is relatively low and I've bumped my head a few times and it's not a good feeling. Here's a fix I discovered: 1) First off, set your desired height by manually moving the trunk to your desired height and "HOLD" the close trunk button until a beep is heard. 2) Now try opening the trunk in a car park and it should open lower than your pre-set height due to obstructions detected above. Once the trunk is opened, press the open trunk button once again, this should open to your preferred height. 3) Try this at your own risk because I think it overrides sensors.
