Engine Standby When Stopped…?

[Dual Grenny Guy]

I switch it off but the other option when you stop is just don't press your foot as hard on the brakes. Then it won't operate.
If you want it to operate at the lights then just press all the way down.
Only time it is a problem for me is if at an intersection waiting to pull out into traffic.
I definitely don't want it to operate then.

I’ve been driving mine for months now and never knew the brake thing. Gonna test it out tomorrow. But in all honesty, I’m just like most on here, it’s simple & quick to just push one button each time you drive.

Forcing it to be pressed and closed constantly will inevitably lead to premature failure and no doubt an extremely expensive fix.

Hotwire?

Hotwire?

I assume it either switches a relay or just sends a signal to the processor.
Obviously it resets every time it powers off so it isn't a physical switch like a light switch.
Whatever solution needs to be momentary only.

I use the finger on my left hand each time I start the car. Occasionally I forget until the first restart.

I used to do that.

I seem to recall this exact same conversation about 2-3 years ago.
I said at the time that when I climbed into my Mercedes I had a standard sequence of selections I did without thinking.

• Foot on the brake
• Insert the key and turn it
• Transmission into sport mode
• Suspension into dynamic
• Auto stop start off.

Now with the Grenadier

• Foot on the brake
• Insert the key and turn it
• Auto stop start off.

Ineos is far more advanced than Mercedes.
Two less steps

Well was it the start/stop function? You said you bet that was it so assumed you didn’t check yet. I also agree with others that’s probably the issue, but you never know……..

Yes it was! I must’ve hit it inadvertently. It really freaked me out because something had obviously changed but had no idea what.

So then is the whole point of this function to save fuel? Bc isn’t it rather… infinitesimal?

What would I do without this place?! So much I don’t know.

Ann there are no odd questions whatsoever.

I have had Stop Start in our Porsches and have had ZERO issues with the stop/start functions. It takes a bit to get used to in our Grenadier but works as advertised.

Does it save fuel? I suppose so. I personally do not have an issue with it at all. We have just learned that is NOT quite as responsive to our other cars. With that being said, after 2000 miles in 6 weeks I understand when it engages and if I know the light will turn I simply lift off the brake pedal and the engine starts. REMEMBER: The Stop/Start works within parameters (what they are I do not know) such as engine temp, HVAC settings, etc.....

I will say that if I am on a dirt road or off roading without "offroad mode" etc...I do turn it off.

I am not concerned about the Start/Stop functionality at all or its potential wear and tear on items in the vehicle.

I will put my "FLAME HAT" on for the responses.....LOL

I have worn that same hat before my friend…..luckily it extinguishes itself in time!! We all aren’t to agree with everything on here……

Euro govts are obsessed with emissions targets. Every gram counts, and when you add up all the cities and towns and the millions of vehicles sitting at traffic lights and in traffic jams for hours , it adds up.
Sitting stationery in traffic is one reason I suspect some countries obsess over cupholders.
I never use them because I don't get stuck in traffic. And I "hydrate" before and after I drive

It also leads to more wear on the starter motor and shorter life for the battery or batteries. As most wear occurs when a motor is started, more wear there as well. Plus start/stop batteries cost more to buy. I would rather use a little more diesel instead, not much fuel is used at idle.

Not enough oil settles during a stop for the "start" wear to occur on a motor, The zinc is coating the surfaces, and the 0w mitigates even more when the engine oil isn't quite up to temp yet. As to how much is saved, one needs to consider the total number of cars running the planet, and where the driver is located. This system just needs a tad more sitting time to activate so it's not such an intrusive nuisance in a traffic jam.

As @ANNML says, it's more of an emissions feature rather than fuel savings... millions of cars sitting at traffic lights really do add up. I think it's a useful feature, but it can be annoying. The most annoying is when it shuts off during a three point turn, stop sign, or a brief pause for any reason. The other is that it's a pretty quick to restart the engine if you ease up on the brake... So if I hit the brake hard to stop at a light, the engine shuts off, I then relax my foot a little and the engine starts back up, though I'm still waiting for the light. Does this when I park sometimes as well, when I pull into a parking spot, engine stops, relax on break, engine starts, turn ignition off, engine stops. Gets a little ridiculous, especially if I used a three point turn into the spot I think I'd rather have the feature off by default, then turn it on when I want it. By the way, putting the car into manual shift mode automatically disables the feature.. this is my current preferred solution.

It also works as this. You brake, the Start/Stop shuts down the engine. You push P on the Lever. Now you can leave your brake free. The car will stay still with the engine shut off. If it turns green, push the brake, shift in drive and off you go.
This gives you less stress on your legs muscles because you don't have to keep pushing the brake pedal all the time. And it is just more relaxed in my opinion.

I sometimes shift into neutral... if you shift into neutral as you brake for the light, then you can coast up to the light for a smoother stop, take your foot off the brake, etc. Engine stays on. Shift back into forward or manual before, or when, it turns green. Almost all my previous vehicles have been manual and I don't like fighting the vehicle to get it to stop, just feels weird. Still wish they'd make a manual, but making do

 

[Tom109]

All these crazy options are like inverted manual start/stop. They make zero sense, just like auto start/stop. It’s a fool’s system. Disable it every chance you get!

 

[Dual Grenny Guy]

So I figured out the trick to stop it…turn the ignition key all the way on & start the vehicle, immediately turn back off, then on again, turn the A/C fan speed to #3 then #1 then off, press the brakes 3 times in fast succession, left turn signal on, then right then left once more, push the driver’s seat all the way back then all the way forward, put the radio on specifically 107.5fm let it play the first song, then mute it, driver’s sun visor up and down 4 times while song is playing, then finally look at yourself in the mirror and ask “wtf am I doing?!”!!

I honestly don’t get it, it is literally one button to push to turn off (yes every time you start it up) but ONE button. Literally 3 seconds maybe 2. Every single time I get into one of mine, I have the following 15 second start up routine…..auto start/stop off, A/C recirculation on, fav button to get the speed warning to slide to off….it doesn’t matter if I get into the vehicle once or 7-9 times in a day running errands, it’s literally 12-15 seconds each time to drive…..if the auto start/stop doesn’t bother you, then sorry you already read this mentally captivating post….

True, but you need also to get out, open the rear door and close it with a big slam. I don’t remember exactly where in the process, but I am sure people will find that out.

Kidding, but I like the start/stop. Having zero issues with it. As I have an early build, this feature wasn’t working and it was on my “Ineos fix this things for me” list. Now after more dan 1 year, it’s finally working.
Maybe it’s because I am European and we have a different drive style or traffic situation. I only shut it off in a traffic jam. There it has no sense to start up the engine each time to drive 2 meters.
