Sensitivity of Auto-On Headlights

[vbbuilt01]

How many have experienced this: Driving with your headlights set to the Auto position, you pass underneath overpasses, through that shadow. Headlights flash on briefly and then off, when back into sunlight. Happens a lot when driving on freeways around the city.

Too me, that's more aggravating that the seatbelt chime.

Problem solved. (dance)

Apparently, there's a lot you can do with that computer buried in the engine compartment. I had this problem fixed today. From the factory, CX-7s have their headlight sensitivity set to "standard". The dealer set mine to "low" today.

Just tell your dealer to set it for you. Doesn't even require PCM flash. There's a procedure found on their tech website called "AUTO LIGHT ILLUMINATION LEVEL SETTING". My tech gave me a copy of it, in case I want to set this back to normal.

Interesting....but I personally like this feature. To each their own.

or you could've searched and found the posts about it already

I have noticed it. Never thought to try to take it to the dealership. Thanks for the info. Maybe I'll have them do that along with the turbo lag PCM flash.

Did they charge you for it?

Oh, I like the feature too, it's just when you go through several successive underpasses, the headlights are constantly blinking. I've gotten some blinking headlights from oncoming cars, thinking I was trying to flash 'em.

(dunno)

Keep in mind, that the auto-on feature isn't disabled. The sensitivity is just tweaked down a bit. I noticed a huge difference in my commute home today.

Peace. Vince

What is the procedure if we wanted to do this our selves?

Thanks,

I did the search. i found the procedure and followed it. Worked exactly as it said it would. Haven't had a chance to try it out. That will have to wait till Monday's commute.

Vbbuilt01: Where can I find the "tech website" you mentioned? Thanks Ed Hayes

Thanks for the tip.

I did a search and so others don't need to search around here are some links.
Here is a PDF for making this change:

And here is the thread that I found the PDF on:

I'll probably give this a try tomorrow.

Well it still pops on and off under overpasses. But it takes longer to turn on when I go into my garage.

So I guess the solution is to drive faster.

Hmmm, interesting. Your experience is opposite of mine. Previously, before the "fix", my headlights popped on almost instantly underneath underpasses. Now, after the "fix", they don't behave that way. The headlights stay off, as I pass underneath overpasses, yet, when I go into a parking garage or night time, they pop on as expected.

Well it hasn't been sunny enough for there to be a difference between underpass and not lately so I'll have to look at it again more closely.

Is it bad for these types of headlights to turn on and off so quickly? Does it shorten their life or anything?
