I just leased a 2010 Rx-450h. The saleman stated it come with the auto dimming high beam, but it was not listed on the sticker. The manual states, the regular light icon, has auto underneath. Is the auto dimming high beams an option or is it standard.
Thanks for any help

The auto dimming lights are not available on the 450h. They are part of the comfort package on the 350.

Don't tell my 450, it thinks it's got'em.

Nothing worse than a pretentious 450, I tell ya'...

it was removed from the bi xenons and is only available for the LEDs

I think people were complaining about how they were too sensitive to reflective road signs and road lights, so it was removed mid cycle.

Thanks for the responses

They are part of a package and are on the majority of RX450h models built prior to March or April of 2010. Then the 'auto dim' feature was removed for some reason. I have them, they work great and I love them. I think they are back in the package for 2011 but not positive.

Take a look on the back side of your rear view mirror. (the side with no mirror) If you have the option there will be a small camera window. This little camera senses the light as it approaches the car. This technology is over 60 years old.
Cadillac is the first to use it. It was in all my cars in the 70's & 80' on the high end cars Cadillac made.

Another pretentious 450h here

thedon, here is a picture of what bluesurf is talking about. You can see the camera lens through the front windshield. I have mine off because high beams are a bit too bright since I changed out the DRL/high beam bulbs. Now they turn off quickly enough but I don't want to blind anyone. It's also congested by me.

Looking at my reaview mirror from the outside, there is a small square lens on the right side of the mirrior looking in. Is that waht you are talking about. Also, the car was bulit in 1/10
Thanks

Sounds like you have the intelligent high beams. You'll need to push the headlight stalk forward to activate it if you haven't already. Do you have the LEDs?

MEP7557

I was referring to the 2011's didn't realize there were tired 2010's still floating around.

2011 450h with the LED headlights does have the auto dimming. The Lexus website is not consistent with it's info.

hmm--drove my wifes car the other evening and the auto bright/dims kept flashing on and then off-first time it happened-drove me nuts.

How do I turn them off (the auto part?)

Johnny

Rotate your headlight switch upward as far as it will go. That is the conventional (or manual) position and the headlights will operate as you are probably more familiar with.

I used this system for a 4-hour night highway drive yesterday, and kept the Auto system active the whole way. The system worked flawlessly, and reacted instantly to either oncoming headlights, or when it spotted the red lights of cars in front.

A poster above mentioned this technology has been around for 60 years. I drove a Lincoln in the Seventies, and remember cars in the Sixties, like Caddies, Olds Toronado & Lincolns equipped with this feature. However, the Lexus implementation which uses a CMOS camera, is much more advanced and much more responsive than the old electric eyes. Back then, you were given a dial-type switch to adjust the sensitivity to-and-fro. The old version did not react to red tail lights, and was fickle overall at best, but it was innovative for its time.

I've tried to use it in and around town, but it flashes on and off much too often (as it should), so I would only recommend using it in rural areas or highways.

The system works very well for me.I do get the shutoff and back on with reflection off street signs at times but it's no big deal.Still a nice feature.
