Reconnecting The Battery

rufels · January 9, 2011

I have had a Lexus 400h for 7 years, and 2 years ago changed to a 2008 model. In the old car I had problems with the small Battery going flat when the car stood for more than 10 days (all discussed on the Forum). All efforts including solar trickle charger and re-starting via the cigarette lighter did not work. Eventually I decided the only way to deal with my frequent trips away was it disconnect the Battery. This is very easily done (even for an old lady), but when I reconnect it on my return many things have to be reset - e.g. the automatic windows, roof window, etc etc.

Now I have one additional problem which I cannot fix - and need help:

WHEN DRIVING WITHOUT SEAT BELT CONNECTED (DRIVER AND /OR PASSENGER), THE RED LIGHT APPEARS ON THE DASHBOARD, BUT THE BLEEP DOES NOT COME ON AS A REMINDER.

Can anyone tell me how to re-instate the bleeping??

Hi - there are some other forums which talk about how to DISABLE the seatbelt bleep (which is usually the default), the instructions cover how to turn it on OR off. Here's one link, there are others.

Actually I'm surprised changing the Battery has switched it off (I'd have thought it would default back to having the warnings on if they'd been previously disabled).

Thanks Neil, In my previous RX400h disconnecting and reconnecting the Battery terminals did not affect it. But this model seems different.
