Honda City CVT Start-Up Clutch Position Memory
For Honda City owners who might have experienced bad fuel consumption after installing grounding cables onto the car, taking out your car battery for extended periods of time or anything that might have caused the ECU memory to be reset, go back to your Honda service center to rectify the problem.
This is an issue with the CVT gearbox, where there is a start-up clutch activated via hydraulics when you shift into D from N or P gear positions. When the ECU memory is reset, start-up clutch calibration information is lost and sometimes the ECU detects the clutch full engage/release positions wrongly.
Please refer to this thread on Temple of VTEC Asia forum where a very experienced Honda driver WongKN has posted his thoughts on the matter.
I believe this information should also apply to Honda Jazz drivers as the engine and CVT gearbox is the same.

its not even failure or a problem. its just a characteristic of certain technology to reset the memory if among the actions eg the batt is replaced for extended period. even computer is needed to restart to when certain thgs is made on. tis is wht u call technology dude. i guess u toyota ppl dont understand since theres hardly any tech in ur cars.
i hv a hi tech watch above rm 1k which need to reset once batt is chged. its a superb watch btw.
dont simply state thgs as u think and sound like a smart aleck. u might get sued for it. u know there are many honda lovers out there.

toyota is using the fool proof technology.. (or so called the older ones)
thus no big problem
and CVT is more advanced compared to the normal autobox
thus there might be some technology flaw in it..
