I have left my 2009 model RX450H unattended for 3 weeks and will expect to find the 12V battery flat when I return to it. If the battery is flat how do I unlock and open the tailgate to access the 12V battery in the boot area for re-charging or jump starting the car? Also if I start the car and want to run the engine to boost the 12V battery charge, or demist the front windscreen before driving off, do I need to select the Neutral gear or will it run whilst still in park?
Please help!
Regards Richard.
