My Prius is notifing me a messege , when the car is switching off (ignition off). This messege does not appear in the short run. Main problem is that I dont know to understand this messege because it is in Japaneese Language. Pls. help me to understand this messege and what should I do for that problem. Thanks,
If you try an online translator, many characters when searching "key battery low" appear as your picture...
That's probably it. Other ppl have reported that the fob battery lasts about 3 years, and the OP has a 2009 Prius.
Just asked my coworker, who is from Japan, it says "key battery". So the key fob battery needs to be replaced.
