ACC

[ColinB]

... In most of my previous cars it was easier/faster to just tap the brakes to disengage the cruise control.

It does the same in the Jazz but the car slammed the brakes on before I could do anything.

The MK3 has two buttons positioned very close to your right thumb, each of which will disengage the CC without undue drama. Much easier than flashing the brake lights and causing concern behind you. Does the MK4 not have similar?

Yes it does. My problem was that the Adaptive Cruise Control decided to apply hard braking when it thought the vehicle in the lane to my left presented a risk. There was no time to cancel CC.

[Kremmen]

In my case it wasn't 'hard' braking but it felt like it was slowing more so than just lifting off the throttle in D mode.

Very disconcerting when it happens. As posted, drivers behind must wonder what you're up to.

Get to roughly the speed you want and press the LIM button. Then use the Res + /  - to fine tune.

Then when the speed limit changes just use the Res + & - again to increase/decrease


If it's as I understand then it's like the old plain CC but you need to keep your foot on the loud pedal.

Yes, in the Mk4 Jazz I don't have to use the brake to disengage ACC as the button is right there on the steering wheel in easy reach.

I use it all the time when approaching traffic as I know the system is about to get into a situation it can't cope with.

You disable it when approaching traffic? This is a bit crazy, and a condemnation of the system, isn't it? Adaptive Cruise Control is all about keeping your vehicle a safe distance from those ahead of you.

Just chucking this into the mix. I have to say I've always thought that CC or, indeed, ACC were unsuitable to use in heavy traffic - indeed the owners manual says as much. I have never used CC when the motorway is busy.

For me the great advantage of CC is to give your right leg a rest. In the MK4 I will use it quite rarely as I did with my Mk3 and any other car I've had. Light traffic on the motorway or an A road.

Yes - the system just doesn't work for me. Just like they say in the specs it has 'low speed follow' and then tell you in the owners manual NOT to use it in heavy traffic at low speeds!

For me, lane keep assist is completely useless too and I never use that either. It has wobbled the car badly before at high speed, upsetting the balance like a learner driver on the motorway for the first time.

Yet, some people get on ok with both of these systems.

I love the car, I just avoid using some of the features as they don't work for me.

When the lane departure system turned itself off recently due to condensation from being parked outside overnight, the car was much more relaxing to drive as I am in the country with winding narrow roads.

I've done my regular Heathrow(ish) to Reading journey.

What I can now say is LIM is the boy for the job and I can't see me using ACC again.

LIM does what it says and you can switch lanes on the motorway with no deceleration interference. I can now go back to waiting for a passing car for example before pulling out behind it to overtake at what I consider to be a safe distance and not have ACC try and keep me in the previous county.

From my garage I turned on LIM which displayed the min 18mph. I then pressed and held RES+ that made LIM go 20 -30 - 40 - 50 then a quick press took it to 51, which is 49/50 on my Garmin DS61.
Once on the motorway just accelerated normally and at 51, no more acceleration,  perfect.

Then when I got to M4 J8/9 where the limit rises to 60, a series of quick presses whilst accelerating got LIM to 61, which is 59/60 on the Garmin.

Proper Job

[Neil Ives]

I use speed limiter a lot.
In my area, (rural Warwickshire) typical 'A' roads are limited to 50mph with frequent villages restricted to 30. I adjust the speed limits as I go. I begin to slow down, (using 'B') before the limit so that without braking I can match it as I pass the sign. I'm happy to report that this causes annoyance to following traffic who tend to drive the same speed regardless of the signage!

[Neil Ives]

I would like to use Adaptive Cruise Control in motorway situations.

[Kremmen]

So would I but the auto braking that ACC performs, well before I would consider slowing down, was irritating.

We all have our preferences and LIM will do me just fine. It's performing just like plain old CC but you need your foot on the accelerator.

That in itself can be an advantage because CC had to be temporarily turned off if you couldn't overtake but with LIM you can just ease off till the coast is clear.

While the idea of plain old CC was NO need for your foot on the accelerator...

Which I said in the final paragraph

[Hicardo]

there's not much more I can add. 

however - if anyone's interested,

I have performed several 500 mile round trips now to Yorkshire from East Sussex.  ive made extensive use of ACC and LKAS. Have not a bad thing to say about LKAS - delighted with it.

With ACC - I guess I think its a little crude compared to the similar system in our Golf.  But tbh I've found myself making good use of it.  I was in a queue on the M25 for 30 mins recently, when people were glued to the road, and it was great or the LSF was - if a tad jerky,  but still more restful than driving stop / start normally. 

im aware its not perfect system yet - but im still a fan overall.
