There are (at least?) three ways to pre-warm the car, at least in my 2011:
1) Timers, set to the time you leave
2) Smart phone (I don't know how since I don't have one)
3) Web through Carwings I think: https://www.nissanusa.com/owners/login
4) Super secret way. Start car charging (I hit the timer override), press start button twice without foot on the brake (I think this also works if you have your foot on the brake and only push button once), then hit "Auto" on the climate control, then adjust temp as needed, then check your work by selecting the blue emissions button and viewing the energy screen. You should see the CC consuming up to 1.2 kW if charging on L1 and up to 3.x kW if charging on L2. I think this also works on DCQC, but don't remember if it exceeds 3 kW. FYI, I didn't come up with this, someone else on MNL posted it a long time ago, otherwise I would post a link.
