what happens if you shift the neutral at a stop light - does the engine still run?

 

1st question I asked when I test drove and the answer is yes. Where the option is though I have no clue. I presume spending a few minutes with the in dash options or manual should yield the answer.

 

Yes, start-stop disable switch is by the headlight switch.

 

Here is a picture - https://pictures.dealer.com/a/alfaromeoofmckinneytxfcaar/0858/d3b1169bca57997b673184c58fe92d40x.jpg

 

My only wish was it defaulted back to last setting after key start instead of having to push it off every time. I've never been a fan of the feature but I'm trying to get use to it.

 

From alfabb forum don't worry about temps, turbo and auto-stop

"Also you do not need to worry about turbocharger temperature when the engine is off. Giulia has the same turbo cooling system (after-run electric pump which can works up to 10 minutes after engine was off) as 4C and american 1.4 Turbo Multiair.

The 2.0 GME has two completely separate cooling circuits: the high temperature loop feeds the engine block and head, engine oil, low pressure EGR and cabin heater, and the low temperature one cools the intercooler and turbo. The HT circuit has a belt-driven pump, while the LT one has an electric pump. Both loops have electronic bypass valves rather than conventional thermostats"

 

My M3 has the same thing which is peace of mind after a spirited drive.

 

Thank you !

 

Start / stop - dangerous situation

I am driving Alfa Romeo Giulia Launch Edition, and I want to share with you a normal driving occasion, with a perfectly normal sequence of events:
Imagine that you are coming to a complete stop by the sidewalk at the end of a trip, and the Start-Stop shuts the engine off automatically. You normally press the Stop button to cut off the engine, but the engine is already off and nothing happens. You release the brake on your way out of the car, but all of a sudden the engine comes to life automatically, and the car jumps forwards.

I find this situation very dangerous and seek an advice.

1. What should I do to avoid this dangerous situation ?
2. Can the Start / Stop be deactivated as a default ?

This wouldn't happen if you put the car in park before pressing the start/stop button to turn off the engine. The car would not launch forward. This was a drivers error.

 

Do manual transmission Giulias have Start/Stop?

I have the same issue. Try to go really light on the brake so as not to activate stop/start before you turn off the car ( push the start button). Whenever I get this wrong it ends up that the car motor turns on an unnecessary additional time. I think this is terrible. We can learn around it but I would bet this ends up in a safety recall ( remember the killer Jeep Cherokee shift lever problems from a couple years back?). I can just see my father-in-law borrowing my car and then plowing it into something as he starts to get out...

 

Yeah, creeping seems to work. However, I wonder whether it stresses the brakes or anything else.

I thought that shifter recall was much ado about nothing. I had two cars with it and never had a problem. It was certainly simpler than the Giulia's shifter and that too is a piece of cake. Maybe fathers-in-law are the problem? My wife might agree.

 

You actually don't have to creep forward. The brakes can stop the car- just don't push harder to engage stop/start.

 

I honestly think the start/stop feature is not that useful, but I also think anyone who is afraid of it launching your car when you get out is a dangerous driver to begin with. If you base your decision to exit the car on the status of the engine being off, regardless of whether you remember turning it off, and regardless of position of the transmission and parking brake, I think you should stick with taxis.

 

I picked up my Giulia Ti about two weeks ago. The start/stop feature is annoying at first, but I can tell you after 2 weeks I hardly notice it. I had been driving an Audi A4 for two weeks (as a loaner) that also had the start/stop, and the Giulia's system is much better, smoother and quicker.


You do get used to it. If you really really continue to dislike it, there is a button on the dash that you just press to shut it off. It could not be easier. I read up about this "feature" and discovered that every new car will have it by 2020 to meet new federally mandated fuel efficiency requirements. It defaults back to the "on" position every time you restart the car, because if they did not do that, the manufacturer could not take credit for the 2-3% claimed improvement in the gas mileage.


I thought I was going to hate it, but I love driving my Giulia so much, this is a non-factor.

 

Auto Start/Stop On/Off Button

Turn off the Auto Stop/Start by pressing the bottom button on the far left of the dash with the "A" (below the button with the "P", the "P" is to turn off the parking assist system)... and yes, you must turn it off every time the car is started. I am a household with 3 new vehicles and all of them have this Auto Stop/Start feature -- I must say that the Giulia's is the best performing of the 3 (smooth/quick/quiet), that being said... whatever car I choose to take that day, I always turn that function off right after starting the vehicle!?!? A little tip to 'get around it', that I have found to work pretty well, is to not press too hard on the brake pedal when having to stop. You can press it down hard enough to stop and stay stopped (obviously) but just don't really press the brake pedal hard and the start/stop feature can be 'tricked' ? Drive it and experiment with it and get that 'feel' for it. Like the lane change blinker vs the blinker or the auto down window vs moving the window down just a bit... same kind of feel and just experience with get you perfect!! (or just shut it off every time you get in) Hope this helped, (at least) a little?!

PS - I just love the **** out of my new '17 Giulia Ti Q4!! (had to add that!)

 

If the driver leaves his/her seatbelt unbuckled Start/Stop won't function.

 

Uhm... save a few drops of gasoline or potentially kill yourself in a crash? decisions decisions.... >

 

Need to use data, not anecdotes. The data on seatbelts saving lives is overwhelming.


There have been isolated cases of pilots jumping of a plane in distress who were killed by being strangled by the parachute. Still, the odds of surviving are much greater if you jump of a plane with a parachute than without one.


Should not make decisions based on individual cases or anecdotes. Need data (science) and statistics.

 

Its 2017. There is absolutely no refuting the safety benefits of wearing a seat belt vs the negatives.

 

To each his own. Just stating that start stop is inactive if driver belt is unlatched.

 

you might as well push the on/off button at the start of a trip ....

 

That chime makes me want to cut the speaker wires....

 

As a safer alternative to not buckling your seat belts, you could always lower your AC to its lowest setting while keeping your windows down. Doing so will prevent the HVAC system from ever reaching the desired temperature and the system will not engage Auto Stop/Start.

 

How much is a starter for a Giulia?

 

I was chatting with @MacGeek a while ago on this subject. He suggested that perhaps a button press simulator circuit could be devised. This circuit would simulate pressing the s/s button when power is first provided to the circuit. He provided a link to a possible circuit that could be used which I'm giving below. I plan to try this when I get my car, but if there's an enterprising EE out there who wants to try first, go for it. Macgeek also provided the switch pin-out for the s/s button but now those pictures seem to have disappeared from my PM message list.
https://electronics.stackexchange.com/questions/245753/generating-a-delayed-pulse-with-one-555-timer-upon-powering-up-the-circuit

 

I ordered the part below and will try it out.
This must be what we need.
time delay timer (momentary, on/off cycle that could be set from .15 sec to many hours,...)
Will post instructions and video once I get it done.

If ever you find the pictures of the switch pin out and intructions to access the light switch in the meantime, it will be greatly appreciated.

Cool, that may work, but I think that the stop/start switch is a contact to ground when pressed, so the circuit would have to momentarily connect to ground and then release after power-on.
Here's a quote from @MacGeek.

It appears that pin 8 should be brought to ground to simulate a button press.

Maybe that together with a relay where the secondary relay circuit is connected pin 8 to ground. Connect the current switch in parallel to the secondary relay circuit so that either the button or the relay will make contact to ground.

Perhaps @MacGeek can post the switch pin-out here.

Looking forward to your results!

this with a relay might work, a momentary pulse- relay closes (connecting to ground)- pulse is over-relay opens

 

you could add this relay

to bring pin 8 to ground.

Hey MacGeek what if pin 8 is wired to ground or does it have to be momentary after car is booted up?

He told me that an error light will come on if the system detects that the button is "stuck".

DTC B1083-23: STOP AND START BUTTON SWITCH STUCK - SIGNAL STUCK LOW

So it needs a single pulse. I'm not sure whether a delay is really needed or not. And you'd have to define the length of the pulse, to make sure the simulated button press is correctly interpreted as a single press.

Also, I doubt it would work to have pin 8 at +12V when the pulse is inactive. That could damage the control module. That's why I'm thinking an extra relay is needed. The output of that timer seems to be either Vcc or ground. What we want is ground or open. I did not see a mode for that in the timer instruction book.
