Hi all, newbie here. Just purchased a certified pre-owned Rogue 2015 with low mileage from Nissan dealership. I’ve noticed that there is no beeping sound in reverse to warn you if too close to an obstruction. Does anyone know how to switch on the sound? Also, they replaced the windshield wipers for me, but the bottom one is still bumping and noisily scraping the window. Anyone have a solution? One other question - how do I turn on the Blind Spot Warning System others are talking about here? Not sure my model has it. Thank you!
