I recently imported an immaculate 2015 Mini-Cab from Japan to Australia being ignorant that all papers, manuals, GPS, Dashcam etc would be only in Japanese! It only had 21000k's on the clock but I would like to know what maintenance is required and how to do it. Thanks Ron from sunny Aus.

I bought this little fellow to play with and found it fun to drive, left parked unplugged at my office and the 12 volt battery went dead, recharged the 12 volt battery, and can not get the hybrid battery to charge or get the car to go into drive mode, eventhou I have 5 bars left on the gas (smile) gauge... is there anything I need to reset if the 12 volt died...??? Help please... Thanks Jim

i suspect that your 12V battery is old, weak or worn out. Even with a recharge it may not have sufficient capacity to start to READY anymore. Recharge fully and perform a capacity check to determine if it is up to the task.

A lead acid battery must be kept fully charged all the time or else it will be damaged by sulfation of the plates.
 
I thought the same thing went out and purchased a new one today, but it did not work, , so have it on the charger all night, but I did check voltage and it was over 12 volt... Crazy thing was, my 12 volt died after sitting parked for about a month, I put my 12 volt charger on it, next day got it started and drove around doing several projects. when I pulled it back in my shop to charge the main battery it just would not go up, hence my thoughts on a new battery, I am going to try it again tomorrow and see if it will charge my main battery.. Sort of scary, its not good for more than 40-45 miles now as it is, but if I can not get her charged... Not going to be worth much at all..ratt finks... (smile)

Thank you sooo much for responding I am at a loss on what to do about this dilemma

It could well be that the 12V battery isn’t the main issue here and the OBC is faulty also. One of its jobs (DC/DC section) is to supply low voltage power all the systems (and charge the aux battery) when in Ready (driving) or charging.

If that’s not working, all the power is coming from the small battery and wears it down quickly, therefore best to check the voltage across the battery terminals in READY (should be >14VDC)
