It was not clear to me, but the Delay and OFF Timers get turned OFF every time you drive the car.
The settings are still STORED and still available, but they don't automagically get used when you plug in to charrge--you must still use the remote everytime that you desire to have delayed and limited timing. This was the missing part for me that is not clearly defined in the manual.
But thankfully found this nugget buried in a post by PV1:
The i-MiEV has no capability for per-day timed charge. The only programming available are one-time start and stop timers. This means that if you get home at 5, plug the car in, and use the remote to set the ON timer to 7 hours, the car will wait until Midnight before starting to charge. Once you start the car and get READY on the dash, all timers are cleared and future plug-ins will immediately charge, unless you set the timer again.
The only "smart" capability the timers have is that they remember the previously set time. So, the 7 hour timer you set at 5 tells the car to start charging at midnight. If you plug in the following night at 8 PM, when you go to set the timer, the remote will come up with 4 hours so that the car will start charging at midnight. The i-MiEV has a non-accessible 24-hour clock that is used just for this purpose so setting a charge timer each night doesn't require math, just turn the remote on, tap right, and tap send.
Not exactly sure, but i think it is necessary to set it twice in order to get the Delay and ON->OFF timers to work--first for the delay, then again for the off? Maybe an expert on this can explain how they use the timers to control charging to less than full.
