TonyC Posted September 29, 2017 Share Posted September 29, 2017 I have a 2018 Legacy and when I use the rear window defroster the top part of the window does not defrost. I see where the top defroster elements are separate from the bottom ones, but I have not figured out how to activate the top part. Also, how do I change the tire pressure units to PSI? I've searched all the manuals and can't find how to do it. I found instructions for an Impreza but the same procedure doesn't seem to work on the 2018 Legacy. Any help is appreciated.

Jsmith Posted September 29, 2017 Share Posted September 29, 2017 I'm not sure about the tire pressure settings because that is new for the 2018. As far as the rear defrost, the top part you are referring to is the FM antenna, not the rear defrost element. Link to comment Share on other sites More sharing options...

ammcinnis Posted September 29, 2017 Share Posted September 29, 2017 ... how do I change the tire pressure units to PSI? 2018 Legacy/Outback Owners Manual, page 3-41 -> Screen Settings.

BigMonkey Posted October 6, 2017 Share Posted October 6, 2017 You're lucky - my 2016 Legacy can't display individual tire pressures, or ANY tire pressures at all. The 2016 model will display a warning light telling you to check your tires (because one of them is low) - it's up to you to manually determine which tire is low, however...

diesel4982 Posted January 9, 2018 Share Posted January 9, 2018 I tried searching for this answer but couldn't find anything. Is there any way, or is there an update to the 2016 limited head unit or ....(not sure what would need to be updated), to allow the tpms identify individual tires?

MrCobbs Posted January 9, 2018 Share Posted January 9, 2018 No there isn't. You will need to get a individual monitor installed on your car with the TPMS. That would be cheaper than trying to replace the entire head unit and deal with programming, etc. Link to comment Share on other sites More sharing options...
