roll-start the Mustang with manual transmission in 2025?

[Dxm]

So there were a few times I had to start my old Mustang when the battery was almost dead. If you're on a hill, you can easily do it yourself:
1. Release to hand brake, while holding the brake pedal and clutch
2. Put the car into gear
3. Release the brake
4. Let the car get some speed ~ 5 mph
5. Press gas
5. Release the clutch for a moment
6. Depress the clutch

Car is now running.

If not, stop with the handbrake and try again.


So this new Mustang has no key. Does anybody know what the proper procedure is to put it into ignition? Is it pressing it twice?
Also with this new parking brake button, how does it work? It needs a battery to be full to work? How do you stop.... the brake pedal will require a lot of force to do anything.

Or should I just forget about this maneuver?

thanks!

Brake is electric, would need power. What year was your old one?

I think forget about the maneuver, 2007 models are very different then current. Back in 2007 many systems were independent and an alternator could power the car, in the years past many/all the electronics rely on each other to function and alternators are very much more limited (controlled) output so steady voltage can be maintained in the electrical system.

With my experience with my golf gti manual with electric parking break is when you have no battery it is done, mine died with start stop one time on a MCDonald’s drive thru and I can’t activate it on a hill, someone helped me with a brick to stop the car because I couldn’t stop breaking, so I guess you can’t release it too without battery

All this stuff nobody asked for, re: parking brake button. I guess It is convenient to have the parking brake auto-disengage. Or auto-engage if you have the the "auto-hold" feature enabled and turn off your car.

But I always have to double-check if I activated it or not. Sometimes it doesn't engage right away. So you may be in a situation where you thought you engaged it, but actually did not. The conventional cable-operated parking brake really became second nature to me after so many years of driving manuals.

So this is kind of still possible but only in a really REALLY niche situation. If your battery is low or dead but you have some kind of power 12 volt power source that is enough to get the computer(s) to power on but not enough to have the starter turn over the engine, with the car in "accessary mode" (which can be entered by pressing the Start/Stop button without your foot on the clutch) you can disengage the electronic parking brake and from "accessary mode" you can perform a standard rolling clutch start. The big issue is that you need to get the computer(s) started up and the parking brake off, but in theory you could do this with a jump pack that is big enough to get things to turn on but not big enough to turn over the engine.
I tested all this on an older 2016 GT so it didn't have an electronic parking brake but so long as the car has enough power to release the brake you should be good.
This was also several years ago and I could have ignition modes mixed up and you may need to be in "start mode" which is accessed in a manual by pressing only the brake when pressing the Start/Stop button and you should get a message about needing to press the clutch to start, just ignore that and pop-start it.
