There you go, that's a really good tip! The wipers are set to wipe automatically, most likely a saftey issue/feature. You wouldn't want a bunch of fluid being dumped on a windshield, and not have the wipers activate while you are driving. (or perhaps they could have a setting where you could choose "no wipe" while in Park, that could work). But this advice of putting the wipers up, while parked is about the best way to get around your concern. We have the heated fluid and almost never use it, seems that when the vehicle is warmed up, the standard washers work just fine. But we haven't had the scenario of ice and/or freezing rain/snow...and our vehicle sits in a garage....so as of now, just haven't had that much use for the feature. However, I do believe it would be very helpful if the vehicle was parked and had heavy frost, or freezing rain on the window. We also have the remote start, so I would assume that the defrost would take care of some of the ice in those conditions anyway. For those rare times when driving, and the windshield starts freezing up, the heated fluid would be a great life saver.medicrxdoc said:I have a friend with a Lexus that has rain sensing wipers. In the snow/ice season, he puts his wiper arms up so the wipers don't wiper over the icy windshield. If you are concerned about that, you could do the same. Our parking lot is full of cars that do this in the winter.
