I had a discussion earlier today regarding the emergency brake feature of my X5 45e.

The other person (BMW specialist) claimed that the emergency brake feature does NO autonomous braking; it is merely an assistant to help you brake.

I starting to doubt myself.

I have the full security pack on my X5 45e, self driving pack and it shows in iDrive the options for it. I have set it to early and all enabled.

In 3 situations I had to apply the brakes myself (emergency brake) because the car did not stop. I was inches away from the car in front of me.

In another situation the car did not detect a pedestrian crossing the street and if I had not applied the brakes, then I don't know what would have happened.

Maybe I rely too much on technology but one of the reasons I got this car is because of its self driving capabilities (traffic jams, highways, ...). I know that as a driver I am responsible. However I'd expect safety features to operate.

I hope that someone can clarify how it is supposed to work (when set to early) and if indeed autonomous braking by the vehicle is supported; rather than just brake assist as that BMW specialist told me.

If you have all the options it will autobrake. You're first warned and if you don't brake the car will initiate braking itself.

There is a city braking function but also a highway braking function.

If you react on the first alarm and start braking yourself . The car will brake with the correct braking power. Is needed full brake. If you don't it will brake autonomously. On the highway this will lower the impact or lead to a full stop depending on your speed.

Already saved me 2 times in my previous car.

You can find info in the manual in botswaarschuwing met rem functie.

In the US spec G05 it works, and has several times in mine. Once with a deer in the road, twice with passing cars in the rear, and almost every time I back out of my garage (about 3" of clearance on either side, and I have the side sensors activated) - I've started using the Backup Assist so I don't get abruptly stopped backing out. Can't verify for a Belgian 45e, but I would assume the same safety systems.

It's also supposed to have evasion assistant where it will change lane if possible and necessary.

Anyone seen this behaviour in action on the G05?

Thanks. So it is clear that it should do self breaking and dealer is wrong.

I find it an important security feature and when now reading your post and that of others, it is a real life saver. Which I thought it to be and that you now have confirmed. Thanks

Bad luck for me, it simply doesn't work on my car.

Did you turn it on? There are different settings from early to late intervention.

Yes it's on early intervention. But it doesn't do anything.

No car without it would receive 5 star NCAP rating.

MystroX5 had his do it when there was an accident in front of him. He posted about the experience, it was about a year ago.

Edit: Here is the link to his post. https://g05.bimmerpost.com/forums/sh....php?t=1580609

If it is on it should work. Only thing is that you could to test is to drive into a traffic jam with 120 km/h without braking to see what happens. But I wouldn't advise that.

In my experience the alarms and interventions I had were really when I was not paying attention on a long trip and didn't see a traffic jam on the highway. I think you will only notice it working when is really necessary.

Or the opposite: not see it working when it is really necessary.

Reading all comments: the features are great so my frustration is growing by the post that it does not work on my car. And by the looks of it, this is not going to be a simple firmware update.

Yeah that's annoying.

Do you get the yellow car in the HUD to warn when your to close to the car in front? If you are really to close it will become bigger and red.

To test auto brake you have to drive fast at an high speed otherwise it will not see it as a dangerous situation. So it only happens when you are really to close and this is difficult to simulate. The car in front of you might do a sudden brake because it looks you are trying to push him out of the way.

Volvo tested city safety with a big cardboard box in the middle of the road ( make sure it's empty).
