I also turn it off when parking since when I am parking I often let the car move without pressing the accelerator. |

Auto Hold is a awesome function in conjunction with auto stop start on tragic lights

Overall, for some reasons, I think it is probably safer to not use it and only use it on hills since your car can slide backwards without Auto Hold. |

Hill-start assist will not hold your car permanently like auto-hold does though, it holds for just a few seconds, but more than enough time to move your feet on brake pedal to the accelerator. |

I think it's a great feature and I use it every day. I do turn it off when parking, as I often move slowly to adjust position precisely in narrow spots and the Auto Hold will sometimes grab to bring the car to a stop.

ive been reading quite a few threads on rear brake pads not lasting as long as the fronts...could this be attributed to the auto hold? Id imagine it will accelerate brake pad wear....

I always use AH, the trick when using it on the city is that you have to break early and slowly/gently when in incoming to a stop light.

Autohold shouldn't increase break wear. Brakes don't wear when stopped and autohold doesn't apply when travelling at any speed.
I would guess the biggiest contributer to brake wear is the brake function on cruise which only works on the rear. I know I'm off track with this one, so to get back on, I love Autohold |

I rarely use auto hold as I rarely see stop-and-go traffic. Used it a few times when traffic was backed up for an accident and a few times at drive-in restaurants. I have never used the cruise control. My brakes appear to be holding up better than most.

Auto hold is useful when you stop your car for a while on up slopes where there is a tendency for the car to roll back if brakes are released. It makes no sense to use on a flat or down hill roads.

After 12 months of ownership I would say the auto-hold is probably the most appreciated unexpected feature of our X3. We both have it on the whole time and only complaint is the need to put it on every time we start the car. Wish we could set it on by default (yes I know it probably can with re-coding). Never had an issue with it. Even with the admittidly very rare reverse parking I have done have left it on. Not concerned about possible increased brake pad because pad changes are covered under the service agreement I have on the car.

I love sitting at a stoplight or wherever without having the hold the brake. It's going to be difficult to go to another car that doesn't have it. Guess I'll just have to get another BMW next. |

The button with the car, slope, and speedo is the Hill Descent Control that helps you descend very steep terrain. Hill-start assist is continuously on, no need to do anything.

It can be useful but it's also annoying when combined with start/stop because you lose your brake pedal control of start/stop and it can end up stopping a lot for <5 seconds at a time, which doesn't actually save you any fuel (or so I've read) but does add unnecessary wear and tear

Now maybe if AH tried to engage at 30 MPH you might see some wear and tear but since it only engages at less than .5 mph there is not enough friction or heat generated to permit brake pad wear. I also like the function. It definitely comes in handy at times. |

Maybe in your case, the inclination was not steep enough to trigger the hill-start assist sensor? You can tell if hillstart assist is activated if you lift off the brake pedal on an incline (with auto hold feature turned off) and press it again, the pedal will be stiff as if the auto hold is on. |
