i have the dimming side mirrors but the dimming effect is so tuttle you can't really tell they are dimmed at all. my corvette and my new sierra have driver only dimming side mirror and the mirror actually turns nearly black!

It seems that my car has this feature without BSM .

The reason why I thought I didn't have it is because I was on the Lexus site and the build your own features for the IS has BSM with rear cross-traffic alert for the Luxury package and BSM for the F-Sport. Maybe the new F-Sport builds now only have BSM?

My paperwork does say I have rear cross-traffic, but I'm not incline to believe everything on it. It also claims I have auto-dimming, auto-tilting side mirrors... which I don't.

If I could, I would load everything onto my IS: memory seats, ventilated seats, heated steering wheel, windshield wiper defroster, auto-sensing wipers, fog lights, park assist, lane departure, adaptive cruise control, rear power sunshade, auto-folding/auto-tilting/auto-dimming side mirrors, power windows up from key fob, power trunk. I'm really lazy apparently... a lot of these features are power or auto.

They are tied to the same option package. You get one, you get the other.

One of the few options that I spec'ed, trying to keep my IS350 around $40k.

There's a green light on the rear view mirror? I only see the red light which is an indicator that the homelink garage system is on. I have BSM as well. I don't think it's an option to turn the auto dimming off and on for the 3rd gen IS, I had a green light for my 2nd gen IS.
