Prius (2004-09) :: Speedometer Backlight Doesn't Dim When Headlights On Auto Setting
Feb 26, 2014
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.

When I turn on the headlights of my 2010 the dash backlight dims considerably. It becomes difficult to see/read when the sun hits it just right...especially wearing polarized sunglasses. I have the dimmer switch set all the way high. Is there a way to increase the backlighting or have it not dim as much with the headlights on?

My uncle just bought this used 2004 Prius for me (with my money) and I'm having some issues.
The car makes some weird noises and I've made a video. Also I think the battery is dying because sometimes the speedo doesn't display and I have to disconnect the battery to get it to come back. The Brake vsc and some other indicator lights also came on. I reset them but they came back in week or so.

My Display goes black when turning the headlights on. Works fine with the lights off. (2008)

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?

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.

Any way to disable the auto-dimming of my dashboard due to lack of light? It seems like when I go into tunnels, the dashboard dims so much that all I can see are the needles.
I suppose I could also turn on the lights, but that seems like overkill.

The backlighting of the steering wheel controls are getting very dim to non-existent.

I have an 04 5.4L SCREW Erratic Speedometer.
Most of the time it works, some of the time it bounces or doesn't read at all.

So my daughter's '04 Jetta SW 2.0 will not upshift and has the engine light on. After having it read by the local shop I have the following codes:
P0743 Torque Converter Clutch Circuit Electrical Malfunction
P0743 Torque Converter Clutch Circuit Electrical Malfunction
P0811 Excessive Clutch Slippage
So what to do? I read a lot about issues about the alleged poorly designed/manufactured stock "Auto Trans Valve Body" and how that seems to be a culprit of shifting issues above 150K.

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?

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).

Noticed a mismatch of 3-4kms between Cruise setting and speedometer? Example, when i set my cruise to 100km/h my speedometer needle actually indicates 103km/h. I took it to the dealer and they said it is normal because the cruise and speedo get their speed signals from different sources.

2004 f-150. When I put the light switch in "auto" position and it gets dark, only the parking lights come on. The headlights do not come on. The headlights work when I put the switch in the "on" position, however. This makes no sense to me.

05 screw with no electrical or lighting mods. The other morning when I left the house, turned on the lights, all of the marker lights, dash, fog, etc. come on normally but no headlights. Placed switch in auto and all works fine, including lights. Move switch back and forth between auto and manual a few times and lights finally come on in manual. Next few days they worked fine. Now again this weekend it did it again. Everything worked fine in auto but no headlights in manual. Run the lights in the auto position and after about 5 min on the road switched back to manual and lights came on. I'm thinking possibly a bad headlight switch or maybe a relay that's hanging up or has a bad contact. I've searched but most of the problems I see are when the lights don't work in auto not manual.

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?

As the title states I have a 2001 f250 with the 5.4 4x4 and lately the auto headlight / overdrive fuse keeps blowing. Both seem to function just fine but a couple of days later the fuse will be blown. I am not functioning the OD button when it blows so I'm guessing its something with the headlights. What else does that fuse protect?

I have a 2015 460LS and having trouble with setting the auto high beams. I have the lights set to auto , push the stalk forward and press the auto button; however, the brights do not go off when approaching oncoming vehicles at night. Am I doing something wrong, or is there something wrong with the car?

I just bought my car probably a month ago. I have a 2006. We checked the air before we bought it, but it was cold outside, so it could have just been blowing out cooler air. Now that it's almost 90 degrees outside, it's blowing out very warm air.
