How do you upgrade my prius v to have automatic day time driving lights?

i know the prius goes nuts when the start battery is weak . i have repplaced the start battery tewice on my Prius.both times the car wad raelly weird. one the new battery is properly istalled the car returns to normal.

Try putting key into key slot. Next try replacing key's battery. Good luck.

i have a 2010 Prius that we bought new. It has had no problems, but I can tell you from my study of the Prius that pretty much nothing is simple. The easiest way to reset stuff is to disconnect the a start battery connection. You can look on the net how to start a Prius with jumper cables to the engine compartment, and disconnect the start battery there. If you are not comfortable with that, the start battery is in the rear near the spare tire. Disconnect the negative cable only, wait 15 minutes and reconnect. You may have to reprogram your radio push buttons, but so what. If this doesn't work, take it to a shop (maybe toyota dealership) that can read and interpret the trouble codes for a 2010 Prius. Enjoy the car, we do.

Yes you can slowly charge the battery in the truck,but make sure the battery is disconnected first,make sure you unhook the neg first then the positive,and when reinstalling it hook the positive back up first the the negative you want absolutely no sparks.I have also had to jump start these vehicles at that battery and had the owners drive them 50+ miles and they were fine after that.For those cars it is recommended that they have to be driven or started for a length of time every day or two.I would call your local Toyota dealer and find out for sure.

Yes the screen dims automatically when the lights are on to suit night driving. I am not specifically familiar with the 01 model, however on my 08 model, the display brightness is also manually adjustable via a button located below and to the right of the display. The button is marked with a series of short lines assembled in an arc. Hope this helps.

could be as simple as you need power steering fluid, which intels you may have a leak, or it could be a bad pump. add fluid, see how long it stays in there, check every day andmore. if it doesnt last a week of driving then you have a leak somewhere. if it does but the problem persits, its the pump

Your car is perfectly fine. Your dash dimmer is turned all the way down. Your dash dimmer automatically turns on with your headlights. You need to locate your dash dimmer and turn it up.( will be easy to locate with owners manual).

are mechanically inclined at all often time when i see a prius come in with the same problem the wire is starting to slide out the back of the harness or bulb socket just push it back in some times it clicks sometimes it doesnt but still pushing it back in resolves either way at 9 times out of ten
