It's just a P and it stands for Park. Some laws haven't caught up to reality and the requirement for parking lights for vehicles is still on the books.
There can be enough juice to run the fuel pump but not enough to crank. That's when a push start can work.
I could have sworn I saw "PE" but ok. So its some legal/manufacturing parking light requirement. I think I'm getting out the wire cutters...
As for push-starting, good to know - so what did you have to do? Get it up to 5? 10? (mph) Did you roll down a hill and engage the clutch? Run with it? I'm really curious how that actually works since I've tried many times and failed every time (I'm pretty sure the pump came on from my recollection).
One last comment - why the heck is the key removable in that mode? Few cars allow that, and if it were not removable, it would be much harder to do by accident. The only thing I can think of is you are supposed to be able to walk away and leave it in that mode and you don't want your bike stolen. (I'm thinking breakdown situation- where you want flashers on - but then why would you want the headlights on?)
BTW, thanks mod for the super-fast reply. I figured I'd have to wait weeks considering how old the thread was. Still, it appears many people have this issue.
As for me, today I came in to work at 8 am, nearly new battery, fully charged. by 11:30 of leaving it in P(E) mode, it was totally dead, no fuel pump movement even, no LCD.
As for the person who got 3 hours out of it, I suspect they had LED headlights or something, or was crazy lucky. I've seen it die after 1-1.5h of being in that stupid mode.
