Wagon owners - how long before rear washer sprays?
08 E350 wagon here. Takes 3-4 seconds (counting in my head, so take with a grain of salt) if I haven't used it in a while. After that it is immediate.

It's actually probably a good idea, in case you still have some summer fluid in the line when the first frost of the year comes. I've never had a rear washer line freeze up on a Benz, but I have on the makes.
