Cindy, don't get too excited yet. I ordered a 2007 RX400h Owner's Manual (N/C since mine had defective binding), and received a 2006 RX350 Navigation Manual. Hopefully you will have better luck on your first try. Tom

Perhaps a Birkenstocks license plate frame would help? Tom

Huh? Where does this statistic come from?

Cindy, I gave up on the site and just called Lexus for a manual. Tom

We have two 2007 RX400h's in our family and both are getting around 23-24 mpg in a combination of short-trip and local freeway travel. Perhaps not up to EPA numbers but neither of our vehicles have had their first oil change yet. If the break-in theory is true, our mileages may increase slightly. And, we both enjoy the performance of our cars and do not intend to "baby" them to try and achieve EPA mileage estimates. We find them to be fun, luxurious cars with a decent amount of performance thrown in. Also the technology is just really cool. FYI, there have been many posts about Lexus's claimed mileage numbers. Neither Lexus nor any other manufacturer "creates" these numbers. They come from very specific testing based on a cycle dictated by the EPA. Blame the government's failure to simulate real-world conditions, or your specific driving conditions, not the manufacturers. Tom

Cindy, if you do some searching here, you will find a few Lexus dealers who discount parts considerably. Tom

As far as exhaust sound, I wouldn't be opposed to a deep, throaty sound from my RX400h, but I doubt that's likely, based on the overall design of the powertrain, and the lack of performance parts for a luxury hybrid vehicle. Just making it loud would be a travesty. Tom

I can only speak for my 2007...the manual specifies "premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required for optimum engine performance." Tom

Man I gotta wonder why you guys buy an expensive vehicle designed to run on premium fuel, then think you know more than the manufacturer and decide that regular's just fine. Do you think that Lexus gets a kickback from each tank of premium pumped?

If so, then why are fuel pumps inside fuel tanks where they are much more expensive to access?

DCFISH, can you show me the link to owner's manuals on the Lexus site? I'd like to look for a 2007 manual. Tom

I don't think that any work that resulted from collision damage is warrantied. Tom

If Mike Tyson drove you car it's probably cocaine. :) Tom

Yes, I would agree, the accessory plugs are probaby not designed to carry so much current (probably fused at 10 or 15 amps). You could always wire your own cigarette lighter plug directly to the 12 V battery (with an appropriate fuse) I guess, and I'd assume that the management system would start the engine as necessary to maintain the charge. Tom

Jim, funny stuff. LOL Yea, Scottsdale is probably not the rust capital of the world, but likely is the chrome wheel capital. Oddly thought, I don't know a single quality chrome shop in Arizona, although I do know several who have screwed up motorcycle parts for me. Tom

Four fuel pumps so far on my 1998 Yukon that my wife routinely runs on fumes before refueling. Could very well be overheated fuel pumps. Tom

I, too am sad, but an also not looking forward to days of non-stop coverage on all the major news channels. You'd think that when a president dies that there are no other newsworthy items. Tom

I have chrome wheels on my 90 LS400 and they look like new in spite of pretty lazy care on my part. They came from my Lexus dealer who I assume had them chromed by an aftermarket company. There is a huge difference in chrome quality, depending on who does the work. Tom

Exactly why I no longer waste my time with the BBB. They're lazy and incompetent. Tom

Ditto, get the new one. I made the mistake of taking a repaint once. Several years later the spot began to show up and it bugged me for the remaining life of the car. Tom

Robl45, the hybrid batteries operate at 650 volts so I doubt that they participate in any of the accessory jacks. And (don't ask me how I know this) if you leave an interior light on and discharge the 12 volt battery, the drive batteries do not contribute to engine starting. Tom

RX400h, unfortunately the actual pressures are not displayed, only a low pressure warning light. Hence my earlier question about the threshold for the warning. I may email Lexus at some point although I expect a politically correct (eg:, evasive) response. Tom

I read it somewhere when I was researching the car, could have been on the Lexus website. Also there was some early discussion here about why they did not include that fuction on the '06. Besides, to measure the pressure directly would require an electrical or pnematic line going to each wheel (like on the Hummer)... we do not have that. Skyfish, my 2007 RX400h the owner's manual states, "Your Lexus is equipped with a tire pressure warning system that uses tire pressure warning valve and TRANSMITTERS to detect low tire inflation pressure before serious problems arise. Before removing the tire from the wheel, remove the system's tire pressure warning valve and TRANSMITTERS. Be careful not to damage the tire pressure warning valve and TRANSMITTERS when removing and installing the tires." That sure sounds like a direct tire pressure monitoring system to me. Perhaps your 2006 and my 2007 are different. Tom

Skyfish, how do you know that the RX400h uses an indirect tire pressure monitoring system? I see nothing to support this in the owner's manual and seriously doubt that Lexus would cut such corners on a $50K vehicle. Tom

I agree, Stan. The 2006 manual must be completely different from the 2007 I have. Tom
