Honda Jazz Mk4 2020 - / Re: Best driving technique for long, steep highway climbs (5–8% gradient)?
« Last post by sebastiand on Today at 11:07:09 AM »Personally I use the mash the pedal approach and turn up the music.Me too, wanna try to feel the 253 Nm torque!
However yeah for a long road uphill, I would definitely go softer.

Honda Jazz Mk4 2020 - / Brake pads still good at 40k!
« Last post by Neil Ives on Today at 10:47:42 AM »My car is currently being serviced. The mechanic always sends me a video of his visual checks. The brake pads are showing only about 20% wear. The car is 5 years old. Mileage is 42k. The brake pads are the original ones. I use B when I'm in town and try to minimise braking.

Honda Jazz Mk3 2015-2020 / Re: bit of a lift
« Last post by TnTkr on Today at 09:40:50 AM »I use next higher profile tyre size in my winter tyres. 185/65R15 instead of 185/60R15. That gives in theory about 9 mm more ground clearance and speedometer shows still more than actual speed, as required.

« Last post by Lord Voltermore on Today at 09:26:57 AM »Make sure your tyres are at the correct pressure. Back in the 'last century' recommended pressures were often in the 20's (with perhaps an option to raise them for heavier loads or high speeds) . A few drivers still cling to the old familiar lower pressures as it gives a slightly more comfortable ride - but uses more fuel.
Also compare your pressure gauge with one or two others. Some are not very accurate.
Check nothing is hanging too low underneath. Maybe an under tray is partly unclipped or an aftermarket exhaust/cat is not 'tucked away' as well as the original.
I'm dont think you will have much success improving ground clearance significantly with diffrent tyres or different sized wheels. The combination of wheel and tyre generally need approximately the same rolling circumference so that the cars overall gearing and speedometer accuracy is not affected .Thus a 15" wheel will have tyres higher side walls than a 16" wheel , with overall size roughly equal. It might be possible to gain a bit of ground clearance by fitting a non standard tyre size but any significant gain may e affect the cars gearing and driveability , and would need to be declared to insurers.
If you are due for a tyre change anyway All season tyres sometimes have about 1mm more tyre tread depth than standard (and of course a new tyre with maybe 7mm tread depth gives a slightly higher ride hight than tyres worn down to say 2mm) Its also possible that an 'XL' (extra load" version of a tyre may have slightly stiffer side walls.
If you do wish to explore options for different wheel and tyre sizes the following site includes data on any ride height gain . But i'd be wary of changing specifications.

No offence intended here. Although some situations are unavoidable (eg grass down the centre of the road' ) you might be able to minimise grounding by upping your hazard perception of the risk.
Cars will often ground when reaching the bottom of a dip, when the weight of the car still pointing down hill when the road rises. This can be worse if you spot the danger a bit too late and add braking to the mix. The front of the car dips even lower under braking. If you can brake and slow earlier you can actually reverse the process by accelerating just prior to crossing the hazard . The car will settle back on its springs raising front ground clearance slightly, which may be enough to avoid grounding. Time this correctly you will not have gained any significant speed when you 'hit' the hazard.

Honda Jazz Mk1 2002-2008 / Re: Powerflex Performance Bushes – Rear Trailing Arm
« Last post by CRC on Today at 07:35:41 AM »Thanks for that, I would say you did very well to do that job in 4 hours especially as I assume you were working on your knees removing and replacing the bushes.
Any problems with the big bush bolts being seized?

Honda Jazz Mk1 2002-2008 / Demister and AC buttons not working Jazz 2005
« Last post by Huntsman on Today at 04:18:33 AM »Hey everyone,
I’ve got a 2005 Honda Jazz, and both the rear demister and A/C buttons have stopped working.
I’ve checked all the fuses and relays, and everything seems to be in the correct place with nothing blown. I’m starting to think it could be an issue with the switches themselves, although it seems a bit unlikely that both would fail at exactly the same time.
I’m wondering if there could be some grime or dirt behind the switches that’s stopping them from making contact. I’m thinking of trying some WD-40 Contact Cleaner to see if that helps. If it works, great — I’ll let you know!
If that doesn’t work, does anyone know if it’s possible to remove the buttons/switches without taking the whole fascia off?
Any advice or suggestions would be greatly appreciated. Thanks!

« Last post by paulhipw on August 11, 2026, 05:31:17 PM »Are you sure the AC clutch is not clicking in.
If you look at the compressor is the clutch plate static or rotating when you turn on the AC?
Also The AC cooling fan should come on when the AC is turned on.

« Last post by TnTkr on August 11, 2026, 04:26:41 PM »Probably Honda has considered relay replacement as workshop level repair task. 
That would be in line with the non-availability of a workshop manual for GK Jazz. Honda wants to keep all repair and maintenance information strictly within Honda dealer network and to prevent users to get that information.

Honda Jazz Mk4 2020 - / Re: Jazz vs bigger cars
« Last post by stefan on August 11, 2026, 04:02:13 PM »Thanks for replies, and back to my original question. We've just got back from a 4,000 km camping trip to Norway in the Jazz, and we've decided to keep it.
A few more test drives since my OP (plus sitting in a Model Y at a campsite) convinced me the step up to an SUV buys almost nothing inside. The HR-V makes the point best with its 319 litres of boot against the Jazz's 304 on the same platform. When I sat in one it felt like a lifted Jazz. Whatever the extra exterior width is doing it isn't reaching the occupants.
Sometime last month after the dealer I also became fixated on centre consoles. Front seats are pretty much the same width in every car, so console width works as a good proxy I reckon for how much of the exterior width actually makes it into the cabin. I peered into many parked cars and eyeballed interiors, which I suspect looked like I was about to steal them. It's a rabbit hole, most of what's down there turns out to be door thickness.
On ride comfort, I'd agree with what was said above, it's suspension tuning (materials, geometry, etc.) rather than size. Anybody who has ridden aluminium and steel frames will know what I mean. The Jazz seems to have been tuned to feel more "sporty".
The gap in my reasoning in the OP is the roof box: it's less about boot litres and more about not wanting a box up there. That's what will eventually push us to a proper MPV rather than to anything in between. We saw a lot of Kia PV5s in Norway and liked how they looked. It's a shame we don't get something like an Odyssey or Stepwgn here in EU...
We'd need only one car either way, since the metro is a minute away and neither of our commutes needs driving.
sebastiand, that's roughly our experience too, though the chassis we have behaves differently. Worth its own thread maybe?

In the jazz boot I managed to fit a huge stroller chassis (Graco evo XT, just the chassis) + a small one (yoyo babyzen) + backpacks etc. All in the boot. I could also have a lot of space for putting a changing mat + kid for changing, in the Jazz boot lol. The boot is amazing.
