So the question is this: Can you shift from D to S whilst in motion and, if you can, do you need to depress the button on the shifter? Is it advisable, can it do any damage?
(tried S mode from rest this morning - it certainly improves acceleration).

Can you use the manual gearchange paddles in both D and S modes, and how do you get back to auto?If you are accelerating and tug the left paddle the car will drop a gear (or give two tugs for even more performance) and stay at the higher revs until you ease off on the accelerator whereupon full auto will resume. Be aware that S mode isn't good for the mpg - I was wondering one day why the trip mpg was about 15% down on normal and then noticed that the gear lever was in S.

For the most part I'll be "wafting" in D mode but I can see S being useful for increasing engine braking, hill climbing etc.

Glad I've got this sorted out because I intend to use S from time to time.
From 'D' to 'S' you need to use the button but not from 'S' to 'D', just push the lever forward.You do not need to close the throttle while going in either direction.
'S' is very useful, obviously for overtaking, but also for joining a road from a side road and navigating roundabouts for instance.
When you select 'S' the revs will rise by about 1000 and the car will become more responsive. When you open the throttle the revs will rise more readily with a corresponding increase in engine noise. Don't worry the engine will not blow up, the red line on the rev counter doesn't start until 6500.
I use 'S' regularly and still return 48mpg.
Vic.

Indeed. I think I will be using it when joining fast moving traffic on a motorway. Another use might be bendy country roads?

Another use might be bendy country roads?It adds a bit of fun and control on bendy country roads but I haven't needed to use it very much. I find that simply pressing the accelerator right to the bottom is enough. In case you haven't found it yet the CVT version at least has a 'click' at the bottom of the pedal travel. No-one is sure quite what it's supposed to do but it seems to open up the very best the engine can give. I don't know if it's on the face-lifted version but if you haven't noticed it you might want to check that you aren't somehow catching your shoe on the carpet and not getting the full pedal travel.

I think you will find the Button as you call it is a kick down switch, when you press it it drops into a lower gear giving you an extra boost.

I think the button Andurec is referring to is the interlock on the gear shift lever, it only stops unintended changes that could damage the transmission. There is a detent near the bottom of the accelerator pedal, this is not a kickdown, by the time you get the accelerator to the stop the CVT has done its ratio change, it just gives full power from the engine. I would call it an economy stop.No, I'm referring to a click at the end of the travel of the accelerator pedal. That's why I wrote:
'the CVT version at least has a 'click' at the bottom of the pedal travel'.
I don't think it's a kick-down button because the manual makes no mention of that and the gearbox will kick down quite readily without pressing past that click. Like you I think it seems more likely to be some kind of 'turbo' (or as you suggest 'eco protect') notch. A way to tell the car 'I really mean it, this time' :)

The manual also has this at the bottom of the pedal travel. It is used to override the speed limiter.

When I want to really move, say overtaking a long artic on a normal road I change to sport, hit the throttle hard then when the revs build, lift off slightly then hit the throttle hard again. The seems to get the max power from the engine.
Most days I'm just drifting down the road at low revs in Atkinson engine mode. I really like this dual mode of driving, it reminds me of half race cams in the old days without the disadvantage of being off the cam and the engine feeling rough.

Now over time i hope to re educate myself to this car as i needed it for carrying my mobility scooter which i have a hoist in the boot and it fits in very good so im well happy.
The thing is in the turbo cars i had when you touch the throttle its like a rocket taking off so if you had the jazz in manual or cvt side by side and came from the turbo into the jazz you would feel like its so sluggish.

Hi my new honda jazz sport cvt i have not driven much yet due to my disability but what i did notice which i will have to get used to was how sluggish it was in d mode holy moly and had to go straight to sport mode which is better but i think its due to cars i had before which were turbo the abarth 145 mta and a skoda fabia vrs estate dsg so i may have been spoiled now that maybe why so many car tests give the jazz a hard time.

To Ad not everyone wants or needs to get to 0-60 in 7 sec or less and with the roads as they are the honda i think will be so relaxing to drive. mind you the 1.5 honda civic turbo would have been good in the jazz.

Try 0 -60 in 3.1 seconds on my Suzuki ( and 0-100 in 8.5 sec) :o the only thing to worry about is a Tesla :-X (unless driver already has range anxiety and does not want to risk flattening the battery).
Post by: andruec on July 07, 2018, 02:24:39 PM
how sluggish it was in d mode holy molyYou just need to be a bit more aggressive with the accelerator. The car is designed to be efficient by default and being efficient means not very powerful. If you want to accelerate like a 'normal car' you need to kick the revs above 2,500 rpm. That will cause the engine to operate in the power mode rather than the efficiency mode. That doesn't mean you have to floor the accelerator but you will have to move it quite sharply downward about 50% of the way. If you barely tickle the accelerator the engine will assume you're happy to dribble along and will leave the engine in 'dribbling along' mode.
Tell the car what you want and it will do it.

That will cause the engine to operate in the power mode rather than the efficiency mode.I recall that the engine has only four of the inlet valves open below around 3,000 rpm. This provides better fuel mixing and efficiency but is a bottlenect to performance and hence the other four inlet valves open at around 3,000 rpm and the engine wakes up (I might be wrong about the threshold revs). The Atkinson cycle mode (which doesn't apply to the Jazz Sport) is a further constraint on the low end power to further increase cruising fuel economy.

IIRC in Atkinson ( as opposed to VTEC 12/16 valve operation on non-Atkinson / older VTEC) all the inlet valves open at lower revs but do not close until piston halfway back up stroke ( to lower compression ratio) when in normal mode the inlets close at bottom dead centre, and maybe at higher revs the inlet valves have larger opening gap and remain open longer on intake downstroke to allow easier breathing at high revs.

If you use the paddles in D mode, the drive soon reverts to auto. I sometimes use them to drop down when going downhill, and it stays in the selected ratio until I touch the accelerator again. Engine braking is minimal, but old habits die hard. I expect something similar happens in S, but I don't use it.
Just to finish the sentence...but in S mode it does not revert to auto when you touch the accelerator. It behaves more like a manual change, but will not let you do silly things. Also in S it never reaches the high gearing available in D mode, so never get the lowest revs possible at 70. I think also the paddles only have 5 "ratios" in S mode compared to 7 in D.

I cant check at the moment, but I don't think you need to press the button in either direction.

Hi i tried in s mode it does go up to 7 but that would be more on motorway its no good around town although i did try that and you soon have to change down.

[I cant check at the moment, but I don't think you need to press the button in either direction.You don't on the Mk1 CVT but when CVT was reintroduced in the 2011 facelift you then had to operate the button to go from 'D' to 'S'.

I'm wrong! As Vic says, D to S needs button, S to D doesn't. I think I do it without realising.
Post by: guest7675 on July 13, 2018, 04:36:44 PM
I think some modern turbo cars are way better less lag and instant throttle at low revs whereas the honda jazz is a in sport mode a car you have to rev higher up the band which to a newbie having gone from an abarth 195 turbo would need to adjust to more revs.
Post by: andruec on July 13, 2018, 04:52:56 PM
The facelifted 1.3 CVT I drove in February appeared not to have the problem so it's possible that Honda reprogrammed the ECU/CVT to remove the issue. It's a pity they can't back port that to us since it's probably just a firmware upgrade.

I was on a deserted motorway early this morning, cruise control, 70 mph. I shifted to sport and call that happened was the engine revs instantly increased by about 1,500. On returning to drive thy slowly dropped back to 2,100 ish rpm. I just wondered what would happen at a steady road speed.This is a useful feature when following a 50 mph truck on a twisty A road, waiting for an opportunity to pass. The response would be quicker than in D.
Post by: JazzyJJ on July 16, 2018, 09:06:22 PM
If you are in S mode and use the paddle shifters the car will go into manual shift mode and an “M” will appear on the display - it won’t revert back to auto like it does in D mode - so you are free to gear up and down using paddles. If you want to get back to auto/cvt mode you just hold the + paddle shifter for a few seconds and the “M” will disappear from the display and you are back in auto mode but still in S.
Read it in the manual and tried it whilst utilising S mode frequently recently.
