Front Window Question

[ThePair]

I've not yet had a chance to get the manual for my 2009.5 TM from the factory (didn't come with one, go figure), but DW asked an interesting question the last time we were out, this weekend: In the event of a fire, how do we get out? Now, for the back window, that's pretty straightforward, there's a lever/latch and you're good to get out. But, for the front window (over the slide couch on the SL), there's no obvious way to get it open, aside from the big "EXIT" sticker in front.

So, I put the question out there: How does one use the front emergency window, in the event of an emergency?
