I'm planning to factory-order the new Mk4.5 Octavia SE L 1.5TSI Petrol Manual. I see Front Assist now comes as standard. My questions are:

1. Does Autonomous Emergency Braking (AEB) work on Manual facelifted Octavias? If yes, does it actually stop the car completely and stall the engine?

2. Have you personally experienced it?

3. I saw one in the dealership showroom and can't see an option on infotainment screen to adjust the sensitivity of front assist. How close to a collision before AEB kicks in and stops the car autonomously?

Thanks.

Do you have experience with a pre-facelift one? If not, I guess the systems are not that different between the versions.

Info for pre-facelift MK4.

1. Yes, AEB works on manuals. It does stop the car completely except if you intervene - input throttle, or the danger disappears. Stalling the engine is the last thing to worry about in those circumstances I think.

2. I have had only one erroneous activation of the AEB in 2 years owning and I didn't let the car stop fully. Otherwise, the system is pretty forgiving and doesn't alert you too often.

3. I've had experience with Suzuki, Hyundai and VW & Skoda AEB cars. The VW & Skoda are the least panicky and alert you later than the others.

I hope this helps!

Similarly, my experience is of pre-FL Octavia mk4 manual car.

Yes, AEB does work with a manual 'box and as @386ka mentions, stalling is the last thing to worry about in such circumstances. Mine has activated a few times in over 4 years and 65k miles and was pleasantly surprised at its effectiveness though I have never had to let it bring the car to a stop as the danger disappeared. Only in the first few months did I get erroneous AEB activation, was fixed in one of the many s/w updates.

As for sensitivity, it is speed aware; by that I mean the faster I am travelling to greater the distance before it kicks in - as I found out at 70mph on the A34. On pre-FL cars there is a setting to adjust the sensitivity - or at least there was when I first got my car. Maybe it is deeply buried in the menus now, but equally I can see the removing that option. Two reasons - reduces the likelihood of us numpty drivers interfering with the safety systems 🙄, or, more likely, reduce development/maintenance costs for the s/w systems.

It can also be disabled if you object to software engineers driving your car by proxy.

One day you may be pleased that the distracted driver behind you has not disabled it in their car...

I have only had my AEB activate at 2nd stage a couple of times (the quick, sharp stab of ABS) when the system thought I wasn't reacting quickly enough.

Never had the system go into 3rd stage (full brake to halt)

Oh, so that’s why you keep yours enabled.
