Anyone know the volume of windshield washer fluid needed to fill the reservoir from empty (low washer fluid level light is on) to full? I checked the Owners Manual, Maintainence Manual, and searched this site to no avail. Also, I assume the process to measure the level with the clear plastic tube attached to the cap would be to put your finger over the little vent hole in the cap and then pull out the tube to locate the liquid level now showing in the tubing? After trying to buy washer fluid in my county (Gwinnett) in GA I was told by 3 seperate Auto Part stores that it is illegal to sell fluid capable of below freezing temperatures! I assume it is due to the alcohol in the fluid or some other chemical contained in that washer fluid to keep it from freezing. I wonder what people do here when it gets below freezing (which it does, was 22F a week ago)
