Using ACC for the first time

[Deleted member 131219]

Having not had ACC before, and having read people's posts of occasional random reactions to other vehicles, I decided I needed to trial it in relatively undemanding conditions; so this morning, I got up at 5am (I was awake anyway due to the heat) and did a full two-hour tour of the M25, with the ACC on the while time. I found it worked well; the road was fairly quiet the first hour or so, allowing me to to acclimatise myself gradually to the ACC's operation. In the second hour, it was gradually busier, so the system was more active and I got to observe it reacting and intervening more and more. All round, a useful exercise. One thing I noticed was that pressing the + and - buttons always increased (or decreased) the speed in increments of 5mph at a time. I couldn;t figure out a way to increase or decrease in 1mph increments. I checked the manual when I got home; am I right in thinking that when cruise is set and running, the SET and RES buttons make 1mph incremental adjustments?

I believe so from reading the manual. I take delivery in a week and was wondering whether the ACC also does the thing where it keeps you in the right lane? Thanks

Yes thats correct

 

[TheUkWizard]

Acc is just cruise control, so will only adjust speed relative to car in front and u can also enable the road sign reading as well. (Which is awesome as adjusts to the max speed as u change zone limits). Travel assist is optional to also turn in in addition to acc. That will literally drive and steer for you as basic autonomous driving

Yes, the SET and RES buttons adjust speed +/- 1 mph, you can also set the distance that car follows the vehicle in front in the main menu. If you watch your graphic in the instrument cluster, you'll see the ACC sense a car in front and start to feel the speed decrease, which you can override with the accelerator if you want. Try it on a normal road and you'll experience it bringing you to a smooth stop behind traffic, you just need to press the accelerator as the traffic moves and it re-engages and follows the traffic at an appropriate speed.

Initially, it was weird having the car control things, but as I've got used to it, I think it's a brilliant system that takes the load off driving in traffic, although do watch for sudden braking if a vehicle turns off in front, it has to be completely clear of the lane for the system to release the brakes, but again, you can simply override with a press of the accelerator.

ACC is one of the most useful things going. My wife's Golf has it and it has been superb for long motorway journeys. I'd spec it in a heart beat these days.

Did your S4 have ACC, @Scotty76 ? I can’t remember.

No I refused to pay the money for it as an option which was about £1400 from memory and always regretted it having tried it as my S4 was a commuting machine and did 250 miles a week on a very clogged M4!

Quite a few people still waiting on their delivery or considering ordering, so just wanted to give my thoughts so far having read some concerining experiences from others prior to me taking delivery in August.
Lane assist :
1. For me personally this hasn't been as aggressive as I'd read/thought. It's just a very suttle pull in a given direction. On most occasions its been due to be being lazy and not indication and expecting it and on the odd occasion its been due to road markings but again nothing to cause a panic
2. On very narrow lanes where motorway road work taking place or due to the markings I've had an audible warning to drive in the middle off the lane. Yes the very first time it came on I went WTF.. But after that it was fine and at most slightly annoying.

3. I did experience the car slowing down twice as I was approaching to overtake cars over a 150 miles drive, but this wasn't aggressive (was in comfort mode) and as I detected I simple accelerated.

The only other thing to mention is the distance setting, I had setting it to the opposite of what I wanted and then was faulting it for keeping such a long distance, once I corrected that it was such a breeze driving on motorway that my 19 year old currently taking driving lessons commented a toddler could drive the car

So in summary, yes I've experienced the reported issues but for me it's not been as frequent and at best a minor inconvenience.

It all depends where you drive. If you have a lot of narrow roads in your area, lane assist might be dangerous.

Do you indicate when avoiding pothole or overtaking cyclist? You certainly don't want to be pulled to the left in such situations.

To be fair it's not difficult to apply enough pressure to the steering wheel to override it, if you are paying attention

 

[Agnes.Surrey]

Or you can just drive without Lane Assist and pay attention to the road, without fighting with the car.

It's hardly fighting the car, it's a mild pressure on the wheel

+1
I was also pleasently suprised how subtle and blended-in it is.

 

[bigcarpchaser]

Not in mine it’s not, practically wrenches the wheel out out of my hands on occasion. Now it’s done it to me me couple of times I’m ready for the b’stard to try and launch me into oncoming traffic.

My Lane assist tried to throw me into the pothole I was avoiding. It's wasn't subtle at all.

 

[Gregums]

My experience to date is as per yak00, it's a subtle pull, nothing drastic and certainly nothing that's difficult to overcome. Narrow lanes in Motorway roadworks are annoying, but apart from an odd 'bleep' and yellow warning, I haven't yet felt sufficiently annoyed to switch the system off. I am aware of the sudden braking as vehicles pull off, but this is easily corrected by pressing the accelerator, and the car responds without issue.

One word of caution though, from a recent A road experience, using ACC and following traffic approaching a roundabout, there was a significant dip in the road and my car started to accelerate, which I presume was the car ahead 'dipping out of radar range'. All easily corrected, and as an assistance system, I was maintaining attention, but had I not, it could have been a messy outcome. That said, these are all 'driver assistance systems', which shows quite how far off autonomous vehicles really are.

Cupra Formentor has its first recall due to the Front Assist system - Car-Recalls

✅ The Seat subbrand's first independent model already has its first recall. The Cupra Formentor must undergo additional configuration of some safety

Yes, it's still a computer that works based on algorithm and with available data. When I see stopped traffic, I start to slow down earlier, by simply removing my foot from pedal. ACC doesn't see stopped traffic until it gets to certain distance and then has to brake much harder. Sometimes it feels like it won't brake on time. That's the difference between driver and computer. Human can see everything in front of him and can take action and computer only sees what's programmed.
