I expect you all know this but today I discovered the 10 mph steps in the cruise control setting. I was slowing down using the CC and held the down button for about a second, it works in 10 mph steps both up and down. Very useful for speed limit changes.
-
It is surprising the things you find out about your car during your ownership. I just realised there is driver's seat height adjustment. Never really noticed the huge big wheel before!
My brother sold me the Carlton I used to have. He had owned it for about 3 years, but only found it had kick-down a week before he sold it to me.

Had driven my Civic for a couple of years before I discovered that intermittent wipers (with adjustable wipe intervals, would be nice to have that on Jazz) are speed sensitive, and go into slow mode when car is stopped at traffic lights etc. I was trying to adjust speed while car was stationary and speed adjustment did not seem to make them go any faster than 1 wipe every couple of seconds, but as soon as I drove off they started going faster.
I did know about tapping speed control to go up or down in 1mph steps but not about 10 mph steps.

Both speed limiters do the same.

You have that on the EX. Unfortunately the auto wipers aren't as good as they were on the Mk2. With those I found a setting that worked pretty much all the time so they were truly automatic. With the Mk3 I'm forever having to adjust the speed to suit the varying conditions :(
-
The cruise control on the Mk2 has the availability of stepping up or down the set speed but in my case it is in 2 mile an hour ( or 1 mile an hour the old fool can't remember) increments or downwards ( can't think of the right word) Very useful in traffic that keeps speeding up and slowing down.
One advantage the Mk3 has over the Mk2 Cruise control is it is adaptive that is it will slow you as well as accelerate OR SO I AM TOLD.
The wipers on our EX I found the adjustment in the fully minus end stopped mine altogether I have it set in the centre. I have noticed that in rain the wipers are very sensitive to amounts and that they react pretty swiftly. Unfortunately they do not respond to West Country misty drizzle until the windscreen is soaked. Can't have it all.
-
The MK3 cruise control can be stepped up or down in 1 or 10 mph steps by the driver. It is not adaptive and does not automatically match the vehicle aheads speed.
-
I thought adaptive cruise control only slows you down if the speed goes above the set point, such as when going down a steep hill?
-
On our way to Straford-on-avon we have to go down Liverage Hill, which in the days of Austin 7s & Morris 8s you had to change down to get up it.
The road has a 50Mph limit and I find that the speed going down in my Mk3 EX CVT will rise above the limit if I let it.
The cruise control does not hold it back, even using the paddles to change down a 'gear' has little effect.
The plus side of all this is, in normal driving, you seem to able to run for 'miles' without using the throttle, which of course augers well for fuel consumption.

I think adaptive cruise control is when the system adjusts your speed to suit traffic conditions. When descending hills most CC systems just lift off the throttle. The Mk3 is no different to the Mk2 in that respect as far as I can tell. I drive the A55 in North Wales now and again and at the bottom of Rhaullt hill I'll be doing over 70mph even though CC is usually set at 60mph.
One of the golf courses I visit has a very steep drive and whilst I wouldn't be using CC there if I lift off at 10mph at the top I'd be doing 30mph at the bottom (probably - no way I'd want to test that). I usually use the paddles to drop the CVT into 1st but it does the same thing the Mk2 did. It'll hold the speed for a while then it will 'release' then it will go back to trying to hold the speed. It seems like the Honda CVT doesn't like continuous hard engine braking.
-
It is Dynamic Cruise Control I am thinking about. I had a hire car in the States that had that system. If the car went above the set speed it would gently apply the brakes, to bring your speed back to the set point.
-

Well if you do use the accelerator it will cancel cruise control anyway, but the car is still using the throttle (you used to be able to feel accelerator pedal moving on older cars with CC). There is plenty on internet that a good driver can get better mpg with a manual car without CC, but you have to be savvy and for most CVT and CC May do better.
-
My automatic Volvo S40 had CC but only the brake pedal or the switch itself deactivated it. If I came up behind a slower vehicle I could accelerate past, and once I took my foot of the accelerator the car would return to the previously set speed.
CC is great on an automatic, but not so much so on a manual.

Hi
I’m sorry as I don’t fully understand cruise control. However on our manual jazz si, I use CC an awful lot, even speeds of 30mph or just below upto my normal speed on motorways
I control speed from the button on steering wheel
The CC will turn off if clutch or brake pedal is touched (does not need depressing) and accelerator pedal, I can use that to go faster then release accelerator pedal, and speed returns to CC set speed (accelerator does not turn off CC)
Where I have used the brake/clutch pedal and CC has turned off, if I press the up button, the CC returns back to last set speed (useful when say coming across roundabouts etc, where you slow down/change gear, then just let CC take you steadily back to last speed)
The only strange thing I have noticed, is at 30mph in 5th gear, driving without CC on, a hill will cause it to labour but on CC, there is not the same labouring, and it cannot change gear
Many thanks
John

Hi all
The only time I've ever used cruise control is in hire cars in France, all of them manual cars like a Renault Laguna for instance. What I did find hard to come to terms with was when I activated the cruise control in top gear from say 45 mph (i know speedo was in Kms) with the CC set to 70 mph equivalent it was like I was accelerating flat out until it got to 70 then stayed there. No gentle build up like I'm used to (my driving style), it was a bit of a shock I must admit. A 2.0L from a 1.2L I know is a jump but was a very strange feeling for me.
-
I am sorry if my suggestion that the cruise control was adaptive on the Mk3. This was put to me as fact. I spent considerable time and effort trying to get Honda to answer the question I put to them. At 70mph in cruise control going down hill on one occasion a lower gear was selected. At no other speed did the cruise control slow me down, the car would run away.
The hill in question is quite steep. The cruise control keeping the speed constant at 70 mph downhill occurred on three occasions. My Wife even remarked on it and she is certainly not mechanically minded.
I put this to Honda, well about six letters telling to go to my local dealer for the fault to be analysed and rectified I finally got them to admit they didn't know. Well I think thats what the letter meant. I found Honda most unhelpful.
Where the adaptive bit came from I know not but it was said in good faith.
I now know the Mk3 Cruise control is NOT adaptive. But my Mk 2 with I shift still slows me down if I start to go over 70 downhill in cruise control
-
My Volvo accelerated smoothly with CC, pretty much as I would have done myself. But what it would do, that explains why mpg is not so good with CC, is it would change down on a hill to maintain speed. I, on the other hand. would back off slightly as I approached the crest, happy to slow by 5 mph or so and not make the change. I have never ever driven a manual with CC (I have driven them, I just never used CC), so I am not able to speak on their foibles.
Driving an automatic, with CC, is mind sappingly dull, and I could well see how drivers nod off. The more driver "aids" we have, the worse it will get.
-
Well if you do use the accelerator it will cancel cruise control anyway
Not on the Jazz it won't. Only the brake pedal cancels the CC. Pushing the accelerator pedal overrides the CC temporarily but it remains in force. Useful for overtaking manoeuvres supposedly but personally I prefer to cancel the CC when I take control. I rely on engine braking to slow so when I take control of the accelerator I'd rather do so completely. Engine braking is less effective when you have CC set at 60mph :)

Never a problem for me as I have the CVT version :P
I use my CC quite a lot on motorways. I prefer to sit in lane one along with the HGVs so I set it to 55mph with the occasional tweak. But I also use it going home from work. There's a stretch of the A422 around Middleton Cheney which is fairly straight and fairly flat so I set it to 50mph (the speed limit).
I don't like using it on bendy roads because it interferes with engine braking nor on hilly roads because it so often under- or over- shoots at the top or bottom.
I found Honda most unhelpful.
My experience too. I once asked them why Idle Stop restarted the engine when I took my foot off the brake pedal and the gear selector was in 'N'. They respond by telling me that if I take my foot of the brake pedal when the gear selector is in 'N' the engine will restart ::)

I now know the Mk3 Cruise control is NOT adaptive. But my Mk 2 with I shift still slows me down if I start to go over 70 downhill in cruise control
Ah well there's a lot of things that iShift did that pretty much everyone is grateful the CVT doesn't do. You might actually have found something where iShift actually behaved in an appropriate way.
CVT boxes (I've used both versions) will hold the current ratio somewhat but as I mentioned in another post they don't seem keen on engine braking. Presumably there's some aspect of their design that means Honda would rather have the engine pushing through the box rather than being pushed. It's never really been an issue for me. I only know of that one hill where CC won't hold the speed and it doesn't cause any issues because everyone accelerates going down there.

Thank you andruec, for your input. The matter of the accelerator overcoming the CC when accelerating is a double edged sword, as I found one day. After slowing in traffic without braking after a distance in CC, the CC suddenly woke up and accelerated. Bit disconcerting BUT then I hadn't used the brake and as you say that does over ride the CC. My own fault for not using the brake. As to the maintaining 70 mph downhill, Honda would not or maybe could not answer my query.
I even asked them if it was a positive of I shift.
