Got a chance to drive Shadowfax on some winter roads. Quoting myself from another thread when it comes to thoughts on the tires and slippery mode:
Two other features that stood out, though in a bad way: rain sensing wipers and lane departure warning.
The rain sensing wipers were terrible in the messy, wet spray from winter roads. Sometimes they wouldn't detect the windshield was being plastered with muddy water, causing me to have to manually trigger them. Other times they would run incessantly despite the mud on the windshield being bone dry. The mud wasn't impacting my vision in any way, so spraying washer fluid was unnecessary other than getting the wipers to stop. Changing the sensitivity won't work because those are opposing situations.
Rain sensing windshield wipers are now permanently disabled, as if I can't trust them in winter I don't want to get used to them in summer.
Lane departure warning was a mess because often in winter the tire tracks wander outside of the lane. This is a natural result of drivers guessing where the lanes are when the lines aren't visible. Then tire tracks wear down to pavement, exposing the lines, and frequently the tracks leave the lane.
Well, in those spots where the line was exposed, the lane departure warning was alerting that I was leaving the lane despite me following the tracks - despite following the tracks being the correct thing to do. This happened repeatedly.
Once again, if I can't trust it in winter I don't want to get used to it in the summer. Lane departure warning is now permanently disabled.
Lastly, I did have a warning come up in the gauge cluster stating "Front Camera Low Visibility Clean Screen". This error would show up seemingly 3 times each drive, about 5-10 mins apart. The warning consumes the gauge cluster display. It could be dismissed by hitting "OK".
This is a
terribly worded warning, especially for those of us with the 360 cameras. Most people don't think of the camera behind the rear-view mirror that handles lane departure warning and automatic high beams since we don't interact with that camera directly. On the other hand, the camera in the grill is one we
do interact with directly. So saying "front camera" and expecting users to understand it's the one behind the rear-view mirror is crazy.
Then they say "clean screen". What screen? I'm trying to figure out why the truck cares about the screen in the gauge cluster or center stack, which would make no sense. Then I'm thinking maybe they meant lens, which
would make sense if they're talking about the camera in the grill (see previous paragraph). But then why would they be monitoring how dirty that lens is? I'll know if it needs to be cleaned when the picture quality is impacted.
In this context, "screen" refers to the
windshield, which is naturally in front of the rear view mirror camera. Outside of North America, windshields are often referred to as "windscreens", so my best guess is this error message was originally written for a non-North American audience and then wound up in the Super Duty as a result of shared software. Otherwise it's bizarre since the Super Duty isn't sold by Ford outside of North America - folks need to go through import companies to get them.
The fix is simple: run washer fluid on the windshield and the wipers will wash in front of that camera, resolving the error. I didn't stumble into this fix because the dirt/mud wasn't impacting my vision, so there was no reason to use washer fluid.
This error is documented on pages 123 and 290 of the 22MY owner's manual (once for automatic high beams, once for lane departure warning):
