Oh, I should add for the very young drivers who may not realize the obvious solution: Just wiggle the steering wheel WHILE pushing the START button, which will free up the steering wheel lock and allow the car to start. That's all one need do.
Note, too, that unlike the conventional key in the ignition lock routine where one turns the key and HOLDS it turned until the engine starts, this push start system does not require one to HOLD the START button down. Just give the button a brief press and the computer will start the car, engaging the starter for as long as necessary.
Think kindly of elderly Porsche as you DRIVE home, rather than walk. We Old Farts can still be useful from time to time.
