Start/Stop. Engine turns off when in neutral with the brakes on, starts when you drop the clutch again. This is always on by default - press the button to turn it off.

Read the manual

+1... when you do look in the book you will find it is the 'Ejector seat' but for safety reasons it only operates in vehicles fitted with a sun roof.

 

Its in the car, that would mean going out into the cold ! I thought I would try the lazy way first.

Cheers Sb, thanks Ben, will inform the missus.

Is it like the below?
If so it's the hill assist - turn this on and when the car is stationary it will hold the handbrake on. When you get to biting point on the clutch, it releases and you move forward. Designed for hill starts - especially helpful in the A5 where you don't have a handbrake lever!

I rarely use it though as it is very annoying in traffic.

How's that any different to just putting the electronic parking brake on?

It still auto-releases (assuming you have your seatbelt on) when you reach the biting point

Doesn't that make the "hill assist" rather pointless?

 

Apparently the only difference is that it stops the "hardship" of having to pull the e-brake button when you come to a stop. I find this so hard to do

So, all-in-all, it still makes the option an utterly pointless waste of money.

 

Hi Paradigital. I have this option and personally, the only problem with having it, is that I don't want to be without it in my next car (first world problem :music-smiley-019.
So i wouldn't consider it a pointless waste of my money but it depends on what you consider useful I suppose.

You could almost say, auto-dimming rear-view mirror is a pointless waste of money too, or auto-dim headlights, or anything that you could do yourself without much effort, but then that would be someone else's gripe.

 

Actually, I hate my auto dimming mirror (on a side note) because it doesn't block enough of the ******* pickup Junkers that shine through my rear glass. :yikes:

It's a uniquely US problem as ******** elsewhere can't afford Junkers that pull 8mpg.

 

I think it must be the start/stop button which IIBen mentioned earlier, its not the hill hold button as its not in that location. It is literally to the right of the strip of buttons behind the gearstick (non mmi)

JB:thumbsup:

 

Confirmed, that location is the stop start button as I have it in my car.

 

...and back on topic, this is the button in question:-

:thumbsup:

I quite like the brushed trim in her car

 

100% auto start stop.

Just in case you're still not sure.

 

I think the hha and electro brake are so close in function that its only a matter of time before the electro brake incorporates hha.

To be perfectly honest hha was designed as a useful feature on cars with traditional mechanical handbrakes.

I agree ssh that all the hha does is automate the electro brake which smacks of laziness but the reality is that hha is a remnant from traditional handbrakes and manufacturers can charge a little more for a feature that is almost redundant, I wager its not too long before electro brakes will self apply and that'll be the end for hha.

 

Ok thankyou guys, that answers that one.

JB:thumbsup:

The above link is to the manual and there is a section on start stop. I haven't read it but its there if you want to take a look.

 

Something to note re hha and the electro parking brake is that the hha operates on the hydraulic brake circuits, applying brake force to front wheels also. It therefore doesnt activate the noisy electric motors at the rear wheels. The hydraulic system is a more efficient way of applying brakes for stop go driving while the mechanical clamping force from the noisy electric motors is probably a better way to apply a parking brake given longer periods of parked up etc.
