Evening all, picked up the Kuga in the week but can't get the start stop to work. I'm used to the system on my BMW so not a novice with it. On the display when the u come to a stand the @ comes up with a line through and it's out of gear foot off the clutch but the engine doesn't cut out, the question is do u need the brake pedal depressed or should it work without? In the BMW u don't need the brake pressed.
also if during the journey I've pressed the @ button and turned it off do I need to turn the engine off again to cancel it, I've pressed the button so it's turned back on but I'm clutching at straws for the reason.
thanks in advance.

If the symbol appears crossed out when the feature is activated it usually means the Battery is not charged enough for the system to allow the engine to stop.

Charge the battery with a charger or a good run

Out of gear handbrake on it should stop

Manual i think is also stationary with clutch down

Automatic Stationary with brake pedal pressed

Doesn't need clutch down or you'd never start it, but there should be plenty of charge in the battery, still not doing it today on way home from work

Apologies my car was an automatic so i knew it worked with the brake.(Stops down starts up)

I had heard that with a manual it works with the clutch pedal so made an incorrect assumption

For a manual it stops in neutral with the clutch up and starts when you push the clutch down

How old is the car and battery?

Plenty of charge may not be enough though, the battery voltage needs to be fairly

high for it to work.

Charge the battery with an external charger and see if it works for a few days after

charging. This appeared to be the dealers answer for KA/500 owners where it seems

the stop start was a gimmick.

Dealer would charge the battery and it would work for a short while. If teh owner had the

car long enough they would replace the battery but mostly it moved onto 2nd owners by

that point.

The car is 2019 and has done 17500 miles so nothing at all really. Be surprised if the battery has worn from that but of course that doesn't mean the battery isn't knackered.
Yesterday temp was 14 degrees so not cold or hot and had a good 40 minute drive to work so plenty of time to put a complete full charge in, and a car working correctly puts a full charge back in in 15 minutes.
Thanks for your input

There can be other reasons apart from the battery.
I have no knowledge/experience of Kuga problems but on the Mk5 Mondeo we have even had cases where a fault on the central fuse box causes the problem - new fusebox required.
If I leave a Mk5 Mondeo, or my BMW, standing for 4 weeks it takes far more than a 15 minute drive to get stop start to commence working again.
How can you say a car working correctly puts a full charge back in in 15 minutes - it will depend on what level.of charge is in the battery in the first place

Because as long as the alternator is working correctly and the battery is ok, no cells gone it only takes 15 minutes to put a full charge back in. Far more effective that way than charging.

Stands to reason that starting the car takes charge out of the battery and that’s why the ASS doesn’t work until charge has been out back.

Guess we will have to agree to disagree then Michael

Also many people on different forums are reporting that their SS have not been working each time they go out for days and reporting that once charged fully with a correct charger things are back to normal

I've been told before by mechanics, albeit RAC and in garages that the car charges more efficiently and quicker than taking the battery off and charging it. Of course if the battery was completely flat maybe 15 minutes is a bit optimistic but most batteries never get completely flat. If you start stop start stop it's drawing the charge out but it's not taking loads out. Don't forget as soon as the cars started it's being charged. I drove to work last night and it was a good 40-45 minute run on the A12, that's more than enough time to get a full charge in the battery IMO and it didn't do what it was supposed to do. I'm happy to listen to what you say as you seem to have experience in the matter. A car though of 2 years does seem a bit early to have a knackered battery although not unheard of but I'd be surprised if it was all down to the battery. But I'll be speaking to the dealer tomorrow and sure they'll do their to fob us off.

It was your quote of a straight 15 minutes that raised my concern. It just has to depend on how low the battery is to start with

My car is just 27 months since since it's build date and 24 months since registration.

After standing for 4 weeks it took an hours driving of mostly main road driving at approx 60mph before the SS started working.

I would have thought your 45 minute drive on the A12 should have been adequate to make the SS work

It would be appreciated if you let us know the outcome of the problem on your vehicle - hope things go well

This charger is well recommended by many people, plus approved by BMW, Porsche etc
