Need help with John Deere 4520 Dash Symbols

[Papa Lar]

I am looking at purchasing a 2012 4520 with a cab. The seller sent me some pictures of the cab and controls. I am having trouble figuring out what options may be installed on this tractor. I can see the Automotive Cruise Control buttons. But I am not sure what some of the other buttons do. The layout is different from the standard one in the owners manual I looked at online. Can someone identify what these buttons do? i have attached a couple pictures with numbers calling out the different buttons. I really appreciate the help.

This is only a guess. 6 looks to me like the low beam on the head lights. I spent years learning to read and now they're using symbols.

I can't see the picture of the dash so well.

4 I think is the switch to activate the Electro Hydraulic third function. I can see the gray wire running down the shaft of the loader joystick for that.

6 I think is rear worklight.

Thanks. This tractor has 3 hydraulics out the back. It looks to me like they are all electro hydraulic with one on the joystick and 2 on the side center buttons. I'm not sure I like that since I am a little old school and used to levers.

6 is the rear work lights on the back of the cab - i tend to use that one more than the others...
5 is motion match
here is the manual: OMLVU19619_E9

Just some extra info. My dealer called the #1 switch "Load Match" It matches your ground speed with the load on the engine/ so you cannot stall out the tractor with this switch engaged. To much load on the motor and it slows up your ground speed. I always leave it engaged. There is no mid PTO because there is no lever, door side of control station. No 3rd SCV because there is no lever on seat side of control station, unless that is now electronic thru the loader joy stick. #6 is the rear work light. Somebody correct me if I am wrong.

Thanks for the input.
I ran across this video that actually helped me out quite a bit.

Not sure if this is the tractor for me because of the hours. But it seems to be outfitted well for my purposes.

It does have 3rd SCV, it is electric, it is on the joystick, and switch #4 is the enable for it to activate the joystick switch.
Switch 5 is the eThrottle like Morrisonsteel said.

Just an FYI. Make sure it is not leaking any engine coolant from around the forward end cover. It will show leakage on the left side of the engine above the water pump. It looks like it maybe coming from the upper radiator hose connection but it probably is not. There is an "L" gasket that face seals from the FEC to the cylinder head, just behind the upper radiator hose connection and that is where it leaks. It is expensive to fix. Repair cost is about 2K as noted by other members. Later
