mystery switches/ holding tank question

I am a complete neophyte at this so please excuse my ignorance.
I have just moved into a borrowed 2002 cedar creek for a long term stay. Some things are pretty straight forward others...not so much.
I see on the control panel in the kitchen that there is a galley holding tank, but can find no dump valve.
Additionally there are two red lit switches, one in the bathroom and one in the kitchen, what in the world is their function should they be left on or off? I am parked in an RV park and fully hooked up. I have the original owners manual which I have found to be pretty much useless except perhaps to find out if the wheels are supposed to be on the ground.
I would appreciate any useful information, tricks and tips that y'all can offer.
Thanks In advance,
H Houghton

Pics are always helpful, especially when you don't include model number of RV.

I can't say with certainty, but if you only see one gray water dump valve, then it's pretty likely the two gray water tanks flow to the one valve. Many online posts refer to multiple gray water tanks with multiple valves, but if there were a second valve you would see it. There's one way to find out. Drain the gray water using the valve. Empty some water into the kitchen tank and then open the gray dump valve again.

I think the switches in the kitchen and the bathroom are for your water pump. If you are hooked up to water, and it appears you are, then the switches should both be off.

Hope this helps.
