It is the auto hold feature that keeps the parking brake on as you release the brakes until you push on the accelerator (up to a maximum of about 5 seconds). This way, you can start on slopes without backing up when you release the brakes. I tried it on the X6 and I found I could not get used to it: I like releasing the brakes myself. But I have not tried in on the X3 yet... Here's hoping it is as much improved as everything else.

To each their own. I've used it a couple of times and liked it each time.

Didn't realize it's only good for about 5 seconds. Good to know before I tried it at a red light while reaching into the back for something!

I think I made a mistake: I read the X5/X6 manual again and there is no mention of the 5-second rule. I definitely waited for longer than 5 seconds while driving with no ill effects. I remember reading about the 5-second delay somewhere, but it must have been for another feature, and I confused it for Auto Hold.

Apologies!

Used it during a test drive and it held seemingly indefinitely. The dealer described it as a "hill hold" function (though I thought BMW steptronics did that automatically, so confused a bit there) but also more as a function for stop and go traffic. Need only use accelerator for short moves and the Auto H function stops and holds you between moves. Don't know if I can get used to that, but it worked on the lot . . .

Tried it. No time limit. It's great. Don't have to put your foot on the brake at stop lights. Just touch the throttle and it instantly releases.

+1 re acer's comments; wasn't sure at first, but after 3 days I think I like the feature. Was a bit apprehensive at first sitting a stop lights and such, but the system held consistently and I realized that if it let go (no reason to think it would) it would be a simple thing to get my foot to the brake. Once I became confident in the system, it produced even smoother take-away from stop (for passenger comfort) than switching foot from break and onto gas and pressing down.
