Auto Hold

[rh71]

My problem with auto hold is I'd turn it on at a long stoplight... then I'd actually forget at the next light and just hold the brake like normal. This has happened on numerous occasions as I try and "learn" to use a "helpful" feature... this is a serious problem!

OTOH the Parking Brake is both hydraulic (when the engine on) and mechanical (with the engine off). The posts I've read about manual release involved the Parking Brake. But maybe I've missed something.

You are right, now that I think about it, those posts I read about could have been related to parking brake failure rather than Auto Hold in specific.

Thanks for info.

If the driver doesn't notice the change in transmission status, then it's freak-out city when the light turns green. Not a complete disaster, but just another reason that I rarely use this feature.

Funny! This happened to me 2 times! I have kids in the back seat, so I lift off seat and reach back to give them something, and when light turns green, the car doesn't move. Step on gas and it practically redlines......Takes a minute to figure out the parking brake is locked, and you have to step on the brake and release the parking brake.....I felt like an idiot sitting there trying to get me car to move forward with cars beeping for me to go and missing a whole green light cycle.......Well, After the second time, I practiced the "motion" of emergently having to release the parking brake, and hopefully this won't happen again......

I guess it's a good safety feature since I suppose there is a risk of using your foot to push yourself off the seat and inadvertantly stepping on gas and ramming car in front of you or running into cross-traffic.....

I use the Auto Hold feature a lot and find it quite handy. I use it primarily in stop and go traffic. I have also had it go into park once without realizing it but now I know how to react when that happens. Its also really useful navigating the San Francisco streets with this feature

On another note I am also enjoying the cruise control. I like the precise control of +- 1 mph or +- 5 mph, you don't even have to look at the speedometer to know your speed. On a recent 500+ mile trip, I practically drove the entire highway stretch using cruise in heavy traffic. My other car is a 2000 540 so I was not used to this type of a cruise control.

Going in for my first oil change tomorrow at 4300 miles, have had my 2010 35d for 2 1/2 months.

Ceck the Owner's Manual for details on the cruise usage. A light press changes the speed 1 MPH, a hard press (past the initial resistance) changes it 5 MPH. The new speed target is displayed as a number in the center display of the dash for a few seconds when you do this.

No offense, but don't know how you can safely operate your vehicle, especially one as complex as the X5 without even being aware of one of its most basic of functions.

God forbid you actually turned the cruise on, without being aware of it, which is incredibly easy to do on the X5 due the cruise control's proximity to the turn signal stalk.

Read your Manual Folks! Yesterday, someone asked what package the heated mirrors came on.

I'm floored. Who here knows when to turn off the DSC and when to keep it engaged. Hint: It's in the manual!

READ YOUR MANUAL for the safety of you, your passengers, and those around you!

If it did, such is life. If people want to honk, good for them. It will give me a better story to tell.

But, seriously, I do use autohold quite a bit. There are a few exceptions. If I'm first at a light and people start to walk across the walkway in front of my X5, I apply the brakes manually. In general, I'll also apply the brakes manually if the intersection in front of me is fast moving. That is, I'd not rely upon autohold to be the only piece of equipment keeping me and my X5 from being sideswiped by a large delivery truck. I'm quick, to be sure, but feet can slip, and attention can lapse.

It's simply unsafe, in my opinion to use autohold in many situations.

I think autohold is a great feature, but I'm not going to place my life or the life of someone else in the hands of BMW electronics (at least not in this regard).

You should sell it then. You are using BMW's electronics to control your fly by wire accelerator. It could just as easily open the throttle and keep it there while you try and shut the engine off with the start stop button that is also BMW computer controlled.

I think you're confusing BMW electronics with floor mats

Right, but time will tell whether Toyota's problems are indeed the floor mats or there is an electronic glitch which led to the run away car and trooper (+family's) deaths. It is hard to imagine a floor mat jamming so tightly that the driver can't kick it away and release the pedal, or in the case of a trained State Trooper, not have the presence of mind to shut off the engine. Who knows.

The point is, elecronics in vehicles (and airplanes) have taken over. I don't see how one system (autohold) is any less trustworthy than the other (e gas).
