Collision alert & active emergency braking?

I realise these functions can be turned off from your steering wheel controls. However once you've turned the collision alert off, does it come back onto the medium setting on restart? If so, can it be turned off until I want to turn it back on again?
I'm not really sure this is a great safety feature on balance anyway. I've had two occasions when the active braking system has broke for me, even when a collision wasn't imminent (close though). First one was when it was on the most sensitive setting, second on it's least sensitive setting. The second one was caused by a car cutting me up at around 60mph, coming over from my right hand side, came close to my front end. A collision wasn't imminent, even though it came close, as I was watching it. Then my active braking system kindly slammed my anchors on :shock: :lol: Just pleased there wasn't a car close to the back of me.
Anyone else had similar experiences? :?

Must have been a pretty scary experience! Did it brake you to a complete stop? Does it give you faith in the system providing its actually needed?

I've had the collision alert LED indicator warning in the dash flash a few times but not actually brake on my behalf.. (yet!)

It was a scarry moment. Went from 60 straight to around 30, emergency brake. Acted before me unnecceserly. Although in that moment of time I realised why. I always turn it off now. Would rather have it off all the time, as you don't always remember to deactivate it. I can see the reasoning behind it, but don't think the technology is quite there yet. It was on the minimum setting too.
I've been driving for over 30 years, managed not to have a serious crash yet. This nearly caused one. Whom would be to blame then? As my car acted by it's self. As the car came over I took my foot off the gas. Then the emergency braking system activated it's self. Due to the car coming close. As I'd said a crash was not imminent though.

You can set it, in the main display setting, to alert only and not brake. I did until I found mine was set on most sensitive, kicking off over anything, even postboxes and cars on driveways. I asked on here how to reset it to least sensitive and did, not had any problems since

Great. Not so much the elert the issue, more the self braking :lol: I shall have a look & def take off the the self brake setting.
Where about in the settings menu on my main display?
Not through my vehicle settings.
Cheers.

Some cars only have the collision alert and some have the active braking too.

Mine just has the collision alert. Where just flashes up on dash. So thankfully I don't have the active braking.

I suppose it's also possible you could have active braking for months without realising you have it. When it does brake there's no forgetting that moment :shock: :lol:
I'm just wanting to know if I can turn it off permanently or at least until I want to turn it on again? Not everytine I turn my ignition in.

For me the lane assist prevented me once to leave my lane easily when a big truck suddenly came onto my lane without using indicators. I saw the truck coming right in front of me and steered to the left for the second lane but the system wasnt too keen on letting me leave the lane. The same thing happend with narrower lanes due to road works. Those safety systems can make situations more dangerous from time to time

If this is true, then i didn't know this!
Makes me wonder if my car has it.
Yeah..i never knew but in the handbook it says collision alert easily disabled then also mentions braking assist (optional)

I had a chat with the service manager and a vaux tec today whilst my car was having a price to get the front wing/bumper clips sorted under warranty. Basically they said this function couldn't be programmed out. So it's a case of switching it off manually everytime you start the car or living with it on the minimum setting. No doubt a new technology we have to live with.
The photo attached is worth a read where basically vaux state within the owners manual that AEB does not always work as it should, in the event of it braking you should firmly press your accelerator pedal down to deactivate it :lol: nice one vaux :lol:

On mine, in the maIn settings, you can tick one of 3 boxes, off, which I thought might cause insurance problems, alert only, which mine is on, or alert and brake. I got that from my handbook, then someone on here told me how to take it off most sensitive at the steering wheel, had no trouble since.
Mine's a 2017 1.4T sports tourer automatic, SRi trim. Can't see why they's make that bit any different on other spec, unless they don't have front assist, but then you wouldn't have the problem. I'll have another look at mine when I can.

Hello all

I want to know if I have emergency braking. I don't have any red LEDS on the dashboard but I have the beeps. I deliberately activated it a couple of times and I know it works. There is also a collision warning that pops up on dashboard. I have also enabled the braking feature. It did not brake on the two occasion I deliberately got it triggered. I got the beeps and the warning on the dash, and that's it. I do not have any radar under the front bumper, only the camera on top of the windscreen. Do I have emergency braking?

My previous Astra only ever self broke twice, I felt the brake pedal go down whilst my foot was on it, along with the dash elert, not something I'd want to experience again. As I've found both the alert and self braking system unreliable.
