Yes, discconnecting the battery would be the simpliest and safest way to take care of this issue. However, my dealer tells me not to do this as it will erase all my settings include the ones for the remote key. So, everything like seat adjustments, automoatic door locks, rear door, etc. would have be reprogrammed by a Lexus Dealer and they might charge for it.

What are others doing to keep their RX400H charged while on an extended vacation? The dealer says the car will not last more than one week and yet the manual says something different. Would you recommend a battery charge and if so, which one?
