2014 Altima 3.5 SL (loaded). I'm still learning all the various nuances and functions available. As a for instance, when the correct psi is achieved [if one finds the need for additional air - or nitrogen in this case], the horn will beep. Go figure. I turned in the 2011 Altima after 3 years with only 25K on it...someone in the used car lot is gonna get a real "peach". I doubt I'll ever use the heated steering wheel, though. LOL
