First time Winterizing, one question

Hello All

I have a 2015 329BHT Lacrosse. I have just one question on step 6 of the manual and I know it maybe a stupid question but thought I should ask before I drive all the way out there. I'm not sure what tank they are referring to can anyone please help?
Thank you

I'm thinking it's the fresh water holding tank. But then I'm thinking that's way to much so it must be the antifreeze

Winterizing With Antifreeze Only
1. Purchase 4-6 gallons of RV approved, non-toxic antifreeze.
2. Drain all tanks (fresh water and sewage tanks).
3. Turn water heater bypass valve to bypass position.
4. Drain water heater.
5. If you have a water filter system installed, remove the filter from the assembly and discard. (You will need to purchase a new one and install it when de-winterizing your unit.)
6. Fill the tank above minimum water pump operation level with the RV antifreeze. (Use of a long funnel may be helpful.)
7. Turn the pump switch 'ON' and open the cold water side of all faucet fixtures. Leave the faucets open until the antifreeze (generally pink in color) flows out of the faucets. Repeat for the hot water side.
8. Flush toilet until antifreeze is visible inside the bowl and pour one gallon of antifreeze down the toilet to winterize the black holding tank.
9. Pour antifreeze down each shower/tub, lavatory sink and kitchen sink to fill p-traps.
10. To winterize gray tank(s), pour one gallon down each related sink drain.

Since it's a 2015 ... Does you unit not have a short hose valved off the fresh water supply for winterizing? That way you don't have to go thru the motions of pouring antifreeze down the fresh water tank ... you can just siphon antifreeze out of the jug directly. I've RV'd for years and don't put a gallon in each tank ... they're empty ... I just pour a quart or so down each sink and tub to take care of the PTraps

Hi Dieselguy

Thank you for your quick response.

Yes I do have a short hose valve that I'm suppose to hook the antifreeze in to. I guess they call it the the winter kit and that's where I got confused because the manual does not mention that from the steps given above.
