I have the same tank in my 2008. I have no idea what it is and tried to trace the input lines but it was getting dark and I closed the hood. I'll look it over again this weekend to try and prove/disprove the water collection theory.

That makes no sense. The water vapor collected in an engine is burned off immediately--it doesn't "go into the engine".....or if your engine runs very cold (like marine engines) it combines with oil to form sludge. And besides all that, this white tank would look like the bottom of a cesspool in about 2 weeks if it was collecting water and oil vapor. And besides that, it would defeat the PCV system, which is designed to re-burn crankcase vapors.
 
But I'm curious, too, as to what it is. Could be vacuum reservoir?

I looked at the white jug again this afternoon and I'm not sure what its purpose is.
I traced the air intake from the top of the grille where it decends at a 90' angle about 12" straight down into a U shape where it then rises 90' and connects to the filter box. At the very bottom of the U there is a female flange on the under side of the intake that fits into a male flange on the side of the white jug. I could see no other lines or any type of drain plug on the base of that jug. It is located directly under the battery on the driver's side. It's either is a water collection bottle or some type of a vacuum bottle.

My Camrys both have this bottle. With no drain visible, it can't serve as a water collector. Could it be a resonator for the air intake? (Seems too large for this purpose.) I've never really given it much thought because it's largely hidden below the battery.

Okay. we have good mystery on our hands. We all agree it's THERE. Now what exactly does ir DO? The air intake pipe is connected to it. Water? Sound?

Allright, so after seeing a number of posts on this mystery bottle, I decide to go out and actually look at my 2007 LE 4 cylinder to see what you guys are talking about.
 
The plot thickens.......I have no mystery bottle under the battery. For that matter, I have no unexplained plastic mystery containers anywhere.

I'm the guy who raised the question...
 
I have a California edition of the 2004 Camry LE 4 cyl. Could the white tank be a California add-on to the antipollution system?
 
The tank in question is large, larger than the coolant recovery tank and seemingly made out of the same material but hidden away under the battery. I owned the car for years before paying any attention to it. There doesn't appear to be any liquid in it. If you have access to a Haynes book, it shows up in the photo of the engine compartment. But without further explanation.

Again, I'm the guy that started the ruckus over the white tank under the battery in my 2004 4 cyl Camry LE.
 
Moving on... I'll join the eternal fray over when to change your automatic tranny fluid (ATF). Possibly never. And the authority for this is Toyota itself. On my tranny dipstick, at the top, there is a little message printed:
 
"Notice: No need to replace ATF under normal driving condition. See Owner's Manual when replacing."
 
Perfectly muddy. It's like sin. Don't do it, but if you do, follow the instructions.
 
Now every dealer on earth will tell you that you live and drive in a not-normal environment. If you live in San Diego, like I do, they will say 'the heat, the heat...' If you live in Fargo, like I definitely don't, they will say 'the cold, the cold...' And so it goes: heat, cold, rain, dust, multiple marriages, etc. Nobody lives under normal driving conditions according to the service writers. One dealer convinced me to drain and refill (this process leaves some fluid in the works) at 15k. Then I read the dipstick. That was the last I've done and now I have 72k. Am I headed for transmission perdition? Perhaps. Toyota leaves us gently hanging in the wind on this one. I think perhaps it will be responsible to drain and refill every 60 or 70k. In other words, 'never' to me means about 60k.
 
No matter where you get this done (ATF change, not sin) make sure they put Toyota Genuine ATF Type T-IV fluid back into it--that's what Toyota meant by reading the manual.
 
Bigger issue: it seems there are all kinds of things you have to do every once in a while even when they don't tell you to. For example, I routinely hold on to a car for 10 to 15 years, 170 to 200k. Every 5-6 years I change out all the rubber hoses and belts because rubber ages badly and if you don't replace it, a hose will pop at 3 am when you're 47 miles from the next service area...
 
So what do you change on your own initiative?

Brake fluid. It absorbs moisture, so it should be changed periodically (at a minimum every 5 years or 50K miles).
 
My Camrys (2004 and 2005) are not California models, and they still have the mystery bottle.
