    I'm getting the 14 blink code on my Hymotion LED indicating that my 12v battery is needing replacement. My question is that the car seems to run fine with the exception of my mileage is low. I'm ordering the Optima replacement. Can I still drive around for another week without worry?

    Thanks!

    I've always used http://priuschat.com/forums/newbie-forum/73400-weird-stuff-happening-mpgs-dropping-test-battery.html but just flipped between off and parking lights. No need to turn the headlights on/off and place unnecessary wear on HIDs (if equipped). I would only do either 12 volt test after the car has sat many hours/overnight.

    Your mileage will drop due to the colder weather and the illusion at high baseline mileage figures (http://priuschat.com/forums/gen-iii...mileage-gets-worse-in-winter.html#post1411488).
