Prius (2010-12) :: Headlights And DRLs Always On, Even On Auto Settings
Jul 28, 2014
I have a 3rd gen Prius (registered in late 2009, but technically a 2010 model), with European "Premium" package including HID low beams and LED daytime running lights. The car has "auto" setting for lights, so I think it should be able to automatically turn on low beams in dark. At least dashboard lighting and the touch & go screen automatically dim, so there must be a sensor (the black dot in last photo, I think).
The problem is that low beams are always on (except in "parking lights only" mode). There is no difference between "auto" and "headlights on" setting. My guess is that this is because of the Nordic legislation requiring headlights being always turned on before 2010 (after 2010 daytime running lights were required/permitted in EU). Whether this behaviour can be changed through OBD programming? It really bothers me to run HIDs on daytime, because in the end all the extra energy is coming from fuel, and also because they have limited lifetime (and probably expensive to replace).

I have the 2012 Prius and wanted to know if there was a way to mod the DRL to stay on with the headlights?
Can I just run the DRL to the parking lights (tapping a wire from the DRL to the parking lights)? Will it pull too much volts?

I finally got my hands on tech stream cable and software and turned off DRL today. I also adjusted light sensitivity setting from normal to light 2. What i was trying to accomplish is to have faster respond of headlights coming on Auto and turning off quickly once it become light again if for example I am going through a tunnel.
I was in the mall today and headlights came on when i enter the garage. When i was leaving it was still light outside and yet even after 1 minute being outside of the cover garage the headlight would not turn off. I finally put it on DRL off and then back on auto and headlight stayed off.
Did i change the wrong setting? Is the result of me putting on light 2 means that while it will come on quicker in dark situation it will take longer to turn off?

I had read that the auto leveling only works when you first turn on the lights. But, I have caught mine doing it in traffic. When I come to a stop behind a car, a second after the front end bounces back, I notice the beams dip down half of an inch, on the car in front of me. I have seen this a few times. Seems the auto level feature is always at work. Is this new for 2012?

Just got a 2014 Prius Three. All my precious cars (non-Prius) had an automatic on headlight system, noticed the Prius doesn't. Can I just replace the turn signal lever with one that has the 'auto' feature? Could it possibly be that simple?

In vehicle settings, there is auto relock feature, i set it up to 60 seconds, the guy who did a walk through with us said, if we leave the car unlocked for 60 seconds it will automatically relock itself. Left the car in the garage for about 5 minutes and still didnt unlock. Is auto relock supposed to relock the car when we walk away?

I bought my 11 GX460 a few months a go and I went out yesterday morning and it wouldn't start.. Of course I left the interior lights on and I drained the battery. Is there a setting somewhere that can automatically turns the interior light turn off after a set amount of time.

I'd like to run my DRL's and Fogs at the same time in auto mode. Currently if you have the headlights set to auto and turn on fogs it enables the regular headlights as well. Id like only the U shaped DRLs and the fogs.

My 2012 Prius has a DRL out. When you turn the DRL's on it flashes for a second but won't stay on. I also appears there is water in the housing.

Is there a way to run the LED DRL's while headlights are on? Vagcom code? euroswitch? Not really too sure just figured I would throw this out there.. Somewhere in the options on the MFD??
I think if your parking brake is engaged they are on but if its just headlights on they turn off. Also I'll just whore this pic of my R ....

Ok here is my situation:
After removing my bumper cover and reinstalling it, my DRLs are dead. The harness is reconnected and the turn signals distress signals work.
I unplugged the left DRL, turn signal to see if the right would work and vice versa and I still cannot get either to come on.
I checked the fuse and that isn't popped.
I turned the car to the DRL marker mode and auto mode and everything works except the DRLs.
I even took the bumper cover off again and inspected the harness.

Since a couple of days whenever I turn the T-reg on even in bright sunshine the lights come on (for night driving and the DRL goes off) when the light switch is in the "AUTO" position. I can turn the lights off by placing the light switch in the "OFF" position and then the DRL lights up (correctly).

I had a new windshield installed and the first time it rained, my auto unlock,the tire pressure monitor and the auto headlights stopped working. The dealer said that the fuse box got wet. I have since fixed the leak but can't find a fuse or reset any where.

New owner of a 2011 Prius II. I have put 600 miles on it so far.
1. Is there a way to make the car automatically lock when I get out of it without having to dig my key out of my purse and hit the lock button or run my finger over the door sensor? It seems to me that once you get out of key range, it should have an option to auto lock - or maybe after a certain amount of time autolock.
2. On a Prius II (no auto setting on headlights) - is there any problem at all with just leaving the headlights in the on position all the time? They turn off automatically 30 seconds after I leave the car, so is there a downside to doing this?

We've use the Auto position for he headlights most of the time since our 2008 was new. Not every time, but too often, the speedometer cluster lighting doesn't switch to dimmed setting when the headlights come on. It seems to happen most frequently when we are in a parade at night. The backlight for the radio dims properly with the Rheostat, but not the Speedometer Cluster. To get it to work properly, you simply need to turn he headlights off and back on again. (or today, open the door)
Sometimes the dim after a 5 second delay (after covering the sensor), and other times, they don't dim after a 20 minute drive in the pitch black.

I recently purchased an 05 prius pack 4, it has an Auto mode on the headlight switch that does not work. as in the headlights do not turn on in pitch black night... From the searches I have done it appears that the car should not have auto headlights and yet it has the switch... I dont think its canadian because it does not have DRLs... if some models DO have auto headlights then what would cause them to not work.

Is it true that on auto setting there is no air blowing out of the center vents? It happened to me this morning with my 2016 GTI.

So I replaced my big fan today. Everyone knows that the factory fans are notorious for going out. After replacing the fan, I turn the car on and noticed that both fans were on... and never turned off. So I turned the car off, and turned the car over again. and they still were constantly running. I messed with the climatronic controls and when I have the settings on auto the fans are constantly running, when I have it on econ, they don't run. And when its on neither, the fans are constantly on unless I turn it off. Before replacing the fan, I replaced both the FCM, CTS, and the fan switch. Its becoming pretty frustrating. I supposed it could act as my own switch for the fans, hahaha. I've searched and havent found anything like this. Hopefully its something small

In the dashboard settings, I set the miles to my previous vehicle. When I turn the vehicle off, it shows fuel cost. I could have swore that one of the vehicles we test drove showed an amount saved instead of pure cost, but for the life of me I can't locate this setting anywhere.

I know there are battery "thingies" that plug into the lighter, which supposedly preserve the settings, but since the lighter is not "hot" when the car is not running, I don't see this working. How to do?
