Adaptive Cruise Control

**jimgironde** · 22-09-2016,08:55 AM

Trying to get used to ACC, only had straight forward cruise control in the past.

Is there any way of switching off the "adaptive" bit? If there is I cannot figure it out.

In the past, if I was cruising on the motorway with cruise control, I could overtake a slower car in front at the moment of my choosing, sometimes this would be at the last moment if I was hemmed in. But with ACC it takes my judgement away by slowing me down!

In my car (with the multifunctional steering wheel) there is a "Mode" button for the left thumb where I can toggle between regular cruise control and ACC. There should be something similar also in cars without the multi steering wheel.

big swede

which mode button is that? I have GT trim and the buttons on multi steering wheel are

o/I for on and off
mode for switching between ACC and speed limiter
plus/minus buttons for incremental speed change
set button
res button
and the centre button with image of a car that sets distance for ACC

none of these switch between regular cruise control and ACC as far as I can see.

Do you have a different button?

Isn't the "mode for switching between ACC and speed limiter" the one you're looking for? "Speed limiter" being old fashioned cruise control?

The speed limiter stops you going over a maximum speed rather than fixes you at a set speed which is what the old fashioned cruise control is.

You either have ACC which will vary your speed automatically up to the limit set by you depending on traffic or you have a speed limiter that requires you to use the accelerator and which will stop you going over the set speed ( unless you engage kick down by flooring the throttle which will disable it).

Only way to get standard Cruise is to get a car without the ACC.

No speed limiter mode acts as just that - it won't let you accelerate past a set speed, but it doesn't maintain you at that speed - that is down to you to do that.

Okay guys, thanks, I have my answer!

I guess I will need to set "distance" to a minimum and overtake in time.

I prefer to travel at my speed and not the speed of the car in front who wants to go slower. Having said that I can see there will be advantages to ACC on occasions.

To be honest I have had similar reservations about ACC as you, but I do think it's just something you have to get used to and adapt your driving to suit the way it works. Once you get used to it, then it works really well. I find the speed limiter function of little use, as it dumbs down the acceleration and responsiveness of the car as it prepares to not let you go past a limit about 10mph before the limit, which can be really frustrating.

Completely agree with you. When I first had speed limiter some years back I thought it would be good for the 50mph average speed cameras, but when you get people travelling at 45mph, at which they are entitled to do, it renders it useless!

For me this is the shortcoming with ACC. Even setting it to very close does not allow it to deal effectively with potential hemming in by slow overtakers.

However, if you apply your hoof gently to the accelerator just sufficiently to overcome the slight resistance you will see the ACC symbol greys out indicating it has been overidden. Lift off and the ACC symbol regains brightness indicating ACC has taken back control. By applying more force to the accelerator to overcome increased resistance you can get as much acceleration as you want at the cost of temporary loss of the ACC safety net (but AEB is still functional, I think). As soon as you lift off ACC takes back control. If you brake instead of lifting off you will have to resume ACC.
