I have a 2015 manual.
Battery was completely dead this morning.

Old skool said turn on the ignition, engage clutch, 1st gear, let go of clutch & she'd start. I've done this a number of times on older cars.

Anybody ever do it with the push-button start? Without power, how do you get it into "ignition on" ???



(as it happens, jumper cables solved this situation short term)

with how complex and electrically-dependent the ignition system is on this car, I don't think there's even a chance it will start with a clutch pop. Ignition, timing, valve lift, cam timing, even the AC compressor is ECU controlled on these cars. ECU can't think without a steady 12v, so the car won't even think about starting until it has some battery power.
