2009 BMW 750i: Auto Hold
August 18, 2009
Our long-term BMW 750 has an Auto Hold parking brake feature. This system automatically sets the parking brake, then releases it when the accel pedal is depressed. The system could be useful when the vehicle is stopped on an incline. But the navi-display owner's manual states that this feature is also a benefit in stop-and-go traffic (?).
In any event, I can understand how an Auto Hold feature can be helpful in a 3-pedal car, but...
I'm not sure if it is much of a benefit with an automatic transmission.
Perhaps it's useful on steep hills at stoplights, even with the automatic.
There are several ways to deactivate the Auto Hold (per the onboard owner's manual):
1. Engine is switched off
2. Door is opened and driver's seat belt is unbuckled
3. Vehicle is braked to a standstill with the parking brake while driving (parking brake is set)
I tried the feature and it works fine on level roads, but you do have to overcome a bit of resistance when you try to accelerate.
I didn't try on this feature on any hills and certainly not in stop-and-go traffic.
Has anyone experienced a similar feature in stop-and-go traffic?
Wouldn't you just keep your foot on the brake and transition to throttle?
If you're that inconvenienced you might as well pop for the ACC (adaptive cruise control).
Perhaps I will evaluate the Auto Hold feature on a future road trip to San Francisco.
But probably not while on the 405.
