Turning off the stop-start?
« on: February 20, 2019, 05:04:44 PM »
Hello all,

After driving about for a bit, I can't say I like the automatic stop-start function. Is there a way to disable it? I can see there is a button for traction control for example, but cannot see anything that will turn off the stop-start?

I think yours will be a Mk2 but you should be able to temporarily disable it. On my car this is a switch near the gear leaver (or automatic shifter in my case) and this cuts it out. It defaults to on again when you restart the engine however. I don't think you can permanently disable it.

Ah bugger. Yes, mine is a MKII. Is there a fuse I can pull somewhere or do something else?  :o

When I got our Mk3 I thought I would hate auto stop, but after a week or two it was a non event. Stopped thinking about it and barely noticed.

Why do you dis-like it so much? It is a fuel and emissions saving device, and since you bought a hybrid presumably these are more important to you than most people?

In the Hybrid I believe the petrol motor is started by the main electric motor so ought to be even smoother.

Wouldn't surprise me if it is not possible to turn off in the hybrid, since it is a whole different animal to the non hybrids.

Surely Stop/Start is a fundamental element of a hybrid system. I can't see why you would want to disable it and why Honda would offer that option. I expect if you attempt to disable it you will completely knacker your car, and if not, you will at least remove any value from the Hybrid system that you paid a premium for.

I've learnt to live with the stop/start system. I had reservations initially but you get used to it and the option to turn it off when it gets annoying is always there. It has become second nature to me to switch it off as I approach home. What was doing my head in was the engine stopping when you came to a halt in the drive and then immediately coming on again as you moved the shift through to Park.

On the CVT I don't like the fact that you can't go into neutral at the lights without the engine coming back on. At a longer stop I find the tension in the old right leg being kept on the brake is, quite literally, a pain. In a manual car, it's into neutral, handbrake on, feet off the pedals. Impossible to do this in a CVT with start/stop.

I did test drive a hybrid Yaris before I bought my current car. There the start stop system was hardly noticeable because when you take off you are in EV mode. Don't know how this works on the Jazz hybrid though.

Not that it helps you much, but on the 2019 HR-V they have changed it.  If you have "Brake Hold" switched on then you can gently brake to a stop to engage it, once engaged, you can take your foot off the brake.  Further pressure on the foot brake when you come to a stop will activate the auto-stop.  Again you can remove your foot from the peddle and it will stay activated.  Hopefully this will find it's way to the Jazz before too long.

The downside, as far as other motorists are concerned, is that the brake lights stay on.

The Hybrid Jazz's stop-start implementation is smoother than that on the Mk 3 Jazz because, when you want to move, the IMA motor starts to power the car so there's no delay due to the engine needing to start. Then fuel gets injected once the vehicle is moving and the engine is turning over so the engine can contribute to the acceleration so the period running as an EV is very short.

I recall that there are situations when the Hybrid's stop-start doesn't activate, one being too many stop-starts within some undefined period in a slowly moving traffic queue.
