As far a the phone, Verizon Wireless works great (with the Bluetooth) but you cannot load all of your contacts. Seems to me that Lexus could have done a better job which would have included all of the major wireless carriers.
 
This is a current limitation of Verizon, not Lexus. Verizon bluetooth support only allows one contact download at a time. Verizon is "thinking" of opening up the software to multiple transfers, but who knows when that will materialize.

Most of teh information on Bluetooth phones for the 400h indicate that all the numbers in your contact list will have to be entered one by one. Of course, I am swithcing carriers from Nextel to Cingular, so I have to enter all my contacts one by one into the phone, so the Samsung T-809 looks good. I will look into the Cingular?Att offering that phone. If anyone out there knows of a great PDA or phone by Cingular that is compatable, let me know........

Real mileage with over 16K miles by hilandr05

Yesterday was the first anniversary of owning an RX400h and I took it in for an oil change with over 16,000 miles.
I have been tracking mileage carefully and have an Excel spreadsheet to show both total and by tank mileage. My total mileage is 27.65 MPG. The by tank mileage varies from a low of 22 to a high of 30. The mileage readout in the car is almost always overly optimistic, by as much as 2 MPG. Of course all this data is not statistically significant without a few facts on conditions.
- Primary location is South Florida, so a lot of flat ground
- Air conditioner running almost all the time
- 2 wheel drive
- Regular gas only
- Combination of stop-and-go, regular street, and highway driving
- A lot of driving too fast, 80+ MPH
- Driving conditions around Miami do not encourage slow starts and moderate speeds.
 
Bottom line is that I know I could do better if I drove slower, started slower, and did not run the A/C ALL the time. But if I just wanted to save gas I would have bought a Prius. I enjoy the comfort, luxury features, and power too much. And I really like driving in the HOV lane!
 
My biggest concern is future maintenance support and trade-in value. I don't see any advertising by Lexus about the 400h but a deluge of advertising for the other cars. I think that is a very bad sign for us owners.

I actually feel like Lexus doesn't have to advertise the hybrids. They don't need the extra promotion. They are popular enough already. That's probably why you are not seeing a lot of hype on them.

For my '07 400h that was purchased in early January, I now have 1,700 miles and mileage is as follows:
 
1. During the cold month of February, I was averaging about 24 with regular gas. With premium or midgrade I was getting 26.4.
 
2. Since temps have risen above 60 F, I am now averaging 29.5 with midgrade gas.
 
I'm very happy with the MPG.

Quick question - do you do most of your driving using the cruise control feature? I had around 22 (at the most) during the colder months, and now that the temp is around 50 I am back up to 25. One thing I have noticed is that the cruise control really makes the difference (aside from the temperature).

Cruise control by kaperino

My 2006 400 h has over 35,000 miles, averages 28 MPG over all with little cruise control. Most driving is around the city, with frequent stops and that decreases the MPG.

I thought that with a hybrid city mpg is higher because the batteries get charged more.

MPG? by ravlegend

2 questions related to MPG:
 
-Mine 2007 manual is recommending premium gasoline (91 octane or above). I've been reading the 2006 suggested regular gas.
Since I assumed they are the same engine - does it matter?
 
-is there a "master" button to show the overall MPG since new?
 
Thanks in advance.

Bought my 2006 in 2005. Have 35,000 miles. Specs recommended 91 or higher. I used the higher grade ( premium) for a year and switched to middle grade. Just a mile or so difference per gallon. Master button? Not sure of the question. I know of no other display of MPG other than on the trip information screen
