what he should have said by katzjamr

it is true that you do not want to run out of gas with this vehicle. what will happen is you have three chances to start the car after running out of gas. if it does not start after the third time, it will electronically shut down to protect the main battery. it then will have to be towed to the dealer to be reset and started. the reason for this is to prevent people from operating the car on electric only when there is no gas in the tank and the engine cannot run to support the battery. toyota is preventing you from possibly ruining the main battery and needing expensive replacement. also for most cars the fuel pump is in the gas tank and fuel surrounding the pump keeps it cool. when you run very low consistently in can cause you to need to replace that pump sooner. when the low fuel light on the dash lights up, you have about three gallons left. i used to be one of those who ran low on fuel before filling up. i dont do that with this vehicle.

Thanks for the detailed explanation. I have to tell the family to WATCH the gas gage.

RX400 slight noise problem by hilandr05
Mar 15, 2006 (5:51 pm)
Only 500 miles on my 400 so I have not gone back to the dealer yet. Before I do, I wanted to check if anyone else has experienced this.
 
At speeds over 30 MPH there is s noise coming from the back that sounds a little like a metallic fluttering. I thought it might be a tag or something loose underneath, but nothing found. With someone in the back seat to help listen, it seems to be narrowed down to coming from under the seat, which would mean possibly something in the battery area. Could it be something with the battery ventilation operation?
Anyone else have a similar experience?
At speeds above 60 the road noise takes over and most of the time I cannot hear it. So I know, the solution is to drive fast!

On our Highlander the license plate was fluttering. On the RX400 the latches for the self retracting cover were rattling. Took a while to find both. For the latches, just push them down into the latched position when the cover is not installed.

It took my more flexible son contorted in the luggage area of my 400h to find this same rattle. It's exactly what you found and repositioning the latches stopped a noise that drove me nuts for an entire 4 mo vacation trip!! Told my dealer, but they seemed amazed like no one else had ever complained about it.

The dealer installed some little adhesive sound insulators on my latches. It seems to be working. They heard the sound, too.

Just got my RX back from the dealer yesterday. I brought it in for (among other things) the same issue. Mine turned out to be an exhaust system heat shield under the vehicle, which I suspected originally. That's why you hear it from the battery vents: the soundproofing probably isn't as thick there. They "made an adjustment" and now the sound is gone!
