Honda Jazz Mk3 2015 - / Re: Auto stop and battery indicator

Done a decent drive today - 80 mile return trip on mainly motorways and other dual carriageways. It is still showing the battery symbol - ie the battery is too flat for it to activate - seems a bit odd to me, I would have thought the 80 mile trip would have done the business.
You might have fallen foul of the battery condition check which is done at the start of the trip although, if your 80 miles was split as 2 x 40 miles, then I would have expected that the outgoing 40 miles would be sufficient to get the battery sufficiently charged to pass the check at the start of the return trip. However, I also suspect that temperature is a factor in the software's deliberations.What was the ambient temperature?

I'm also baffled by the characteristics of the batteries used for the stop-start systems. On Friday morning my HR-V's battery was 11.8V after standing for 3 weeks. The engine started fine followed by a 4 mile trip to the local Honda agent for the annual service which reported the battery as good at 12.32V.

It was about 7 degrees going out and about 10 degrees when I started the return leg. I'm not overly concerned (I'm agnostic on these systems) but I might do a voltage test.

Honest John has a horror story with a Nissan Cashcow ...
"Nervous brake-down
My son has a new Qashqai with manual transmission (3 weeks old) and on the motorway this week had a problem with the cruise control. It was set at 70mph and, as traffic slowed in front, he applied the brake but the cruise control did not disengage. He ended up causing damage to another car and some scrape damage to his own. The cruise control was still active on the hard shoulder. Can you help? Have you had any reports of problems with cruise control? Also, on the same journey, as he tried to join the motorway with the road completely clear in front, the car automatically did an emergency stop. The car is being repaired this week and then Nissan will test the cruise control. Any advice for him?

What price fully automated car reliability? :P

I would have been expecting a reading of 12.6 volts for a good battery. I was following a Merc in crawling traffic the other day and it obviously had stop-start, every time traffic moved the cars tail-lights dimmed and it gave a 'shudder' as it restarted - as an engineer it did not look good to me....   I saw an article on a guy with a Ford Mondeo who had a battery fail on his car, a new battery was fitted but he still had problems with battery charging, anyway after going to the Ford dealer and some investigation he was told that the wrong type of battery had been fitted and it was fooling the 'smart charge ' system that is designed to protect the battery from excess charging when battery temperature is low and also 'optimise' charging in normal driving to take load off alternator and improve MPG.  When correct type of battery ( AGM or calcium I think ) was fitted everything went back to normally.  So it seems that even the slight differences in charging voltage and chemistry between battery types can badly affect the operation of smart charging.  The heart of the smart charging is temperature sensor and a current flow sensor on battery positive terminal, and I think most modern cars have these, including Honda.

Hi Roddy,
You have2 cig lighter sockets on your car one in arm rest plus a USB socket.
And the same on lower dash area behind Gear lever,I use cig socket in Arm Rest for my Dash Cam no wiring showing,  and the other cig socket for Sat Nav with no worries.this arrangement leaves 2 USB sockets for other requirements.
I have just looked, appear to only have one cig lighter socket, usb and hdmi at bottom of dashboard and one usb socket in arm rest.....

That makes a difference. Mine is 42 litres.
A minimal difference though.

Just a little bit of info relating to my car and its Auto Idle Stop system. It hasn't operated for about 6 weeks now and shows the battery symbol when it doesn't activate.

I think car makers aim for a certain range from a tank so a more efficient car will get a smaller tank capacity. Carrying extra fuel is a weight penalty and makers try to squeeze last grams out of weight, even to the extent of not supplying a spare wheel....... and sometimes even skimping on sound deadening.

Honda Jazz Mk1 2002-2008 / Re: Which is top range Sport or Sport SE?

The later sport model has climate control, front fog lights, different alloys and some other detail differences
