Question type: Maintenance & Repair

I have a 2003 toyota prius, there is a
fluid container located next to hybrid
battery area under hood, trying to
figure out what it is for. It is below the
LOW level. The cap says DENSO on
it

Ok, it's just seems weird for it to be an overflow tank since it had a FULL line and LOW line marked on the side... The engine coolant container is over on the left hand side under hood.

That's why I took if off, had second thoughts. But does it say anything else on cap. Like ":use only XXX fluid "?

Its called INVERTER COOLANT FLUID!! Must be changed every 120K miles. It has to do with your car's A/C and heating and is related to the water pump.
