So there's this button...

[Bobt]

Hi. I'm new to this forum and new to my 2015 jayco precept 35un. There's this little button on the very lower left part of the dash board. Almost parallel to the emergency break. It's a simple on/off button with no labeling whatsoever. Can't find any reference in the owner's manual. What the heck does it do? Eject the wife when she talks too much? Dispense water in the dog's bowl? Yes...I've turned it on and off and nothing seems to change. Thoughts?

In my 35UN it launches the side winders to clear the road ahead! I am not sure of what button you speak of, I will look at my 2015 35UN when I get home. Although mine is listed as a 36UN, I have the prototype for the 35UN!

If you hear a little "click" when pressed, it may connect the house battery to the starting circuit, in case the starting battery is dead. Just a thought.

I have a 35 un 2015 just looked at mine no switch except a switch to dim dash lights. Could that be what you are seeing?

It's the seat EJECT button to launch your spouse out of the RV when they're nagging you.

It's probably the Unicorn fuel fill button. Push it when you're below 1/4 and the tank fills by itself��

It is incase your chassis battery goes dead while camping.. it adds the house battery to the starting circuit. (at least that is what it did on my GF's Redhawk )

I checked mine, I do not have a mystery button, I have a blank filled spot where if I had power shades the control would be, other then that there is nothing, The battery boost button is labeled, it's near the Leveler controller.

I have a 35S and will look at mine when I get home. You should post this question on the Jayco Precept forum for more responses.

Can you please tell me how to add this button to my TV and TT?
I would pay extra for it, give blood, etc!

Google it, there are many types depending on your vehicle like the links:

Good luck, I've heard you usually only get one shot at it.
