Hi All

I have question I rarely drive my car maybe 100 miles a month. Ie most of the time its sitting outside. If I leave the panoramic sunroof shade open in the hot sun will it be bad for the leather and other interior fittings? I have 2016 RX with the semi-aline brown leather. I also read that automotive glass is UV reducing so not sure if i really need to remember to close the panoramic glass shade each time.

Thanks,
