Hi everybody.
I just purchased a Phantom 2 Vision +. I've used it a few times but I have yet to know the functions of the buttons S1 ​​and S2 buttons. Can you guide me? Thank you so much!

The best advice I can give is to read the manual, then keep reading it until you understand all the functions.
S1 and S2 don't really do anything interesting if you are flying in Phantom mode.
If you get into a Return to Home mode S1 will allow you to regain control.
But for normal GPS flying both switches should be up.

True. I have a new PV2+ too. I much prefer watching youtube to reading instructions, but in this case, I've decided I really HAVE to sit down and read the instructions. I'm not going to fly it until I understand every function. Then I'll crash it...

LOL well at least after reading all the manuals you will know why you crashed.....
The DJI videos on YouTube are good, and knowing the start up routine and confirming GPS lock before take-off should help to keep you out of trouble.
The phantom really is very good at flying itself, you have to try quite hard to crash it....

This is the best thing I have learned about the switches and is great for newbie:

You can enter S1 search for it in the PDF user manual

User Manual V1.4 page18:
The S1 switch is used for compass calibration. Toggle the S1 from position 1 to position 3 and back approximately 5 times to enter into compass calibration mode.
In Naza-M mode, the S1 switch is used to switch between control modes and enter compass calibration.

S2 is used to record a Home point manually. After a Home point has been recorded automatically, flipping S2 from position 1 to position 3 and back 5 times (or more) rapidly will move the Home point to the Phantom’s current location.
In Naza-M working mode, S2 is be used for IOC.

Calibration Procedures


User Manual V1.4 page28:
4.3 Regaining Control During Failsafe Procedures
When the S1 switch is switched to Position-1, toggle the S1 switch to any other position once to regain control. If the Remote Control signal is recovered, control is returned to the pilot.


User Manual V1.4 page44:
If you wish to regain control of the aircraft, toggle the S1 switch on remote control from (Position-1) to either (Position-2) or (Position-3) to discontinue the current mission.

Dude...you know this is a Zombie Thread from 6 months ago...it is quite possible that some of the folks, including the OP, are not even following this forum for now or possibly ever.  In either case they stopped following this thread a long time ago.
