  1. When my dad drives the car I get seasick from the "lurching", I am of the assumption that it's his foot & the sensitive gas pedal that are the culprits because in cruise control I dont need gravol when he is driving.
  2. I just noticed that the RX400h on the back is blue. Its actullly crhome with blue in the middle. Subtle.
  3. Ya, I haven't had it long enough to tell. Its been below 50 since I picked it up and it will not get above 50 degrees for another 6 months :cries: I am not getting very good mileage averaging 22mpg on the highway (going 75) on 200 mile trips. I am averaging about the same in the city with the short trips. Once it is warmed up I can reset the mpg and average around 35 in the city. When I take it in for its 5k checkup I will ask them to run that ICS or whatever it is to recalibrate the system.
  4. NOTE: The only thing powering the back axel is the rear electric motor. The gas engine will not touch the rear wheels.
  5. :P You can figure about 1 lb air pressure for every 10 degree F change, given a cold tire and sitting overnight. It should be noted that the recommended tire pressures are for COLD tires. That means they have been sitting overnight, but it assumes standard day conditions (i.e. sea level and 75 deg F). If you are going to adjust your tire pressure, it is best to fill them up at local air source (unless you have your own) the night before and then "drain" them to the proper setting the next morning. If your morning is 65F or 55F then you can subtract a pound or two from your target setting based on the above formula. NEVER SET THE TIRE PRESSURE AT THE FILLING STATION! They will be severly underinflated. I have a digital pressure guage and just use the air at my local filling station to fill them up. I am pretty sure COLD means something completely different up here than most other places :P
  6. Uhh, where would one be able to fill up their tires with Nitrogen?
  7. I just checked my tires again and they are now at 36psi. The temperature is dropping :cries: I didnt think temperature would have such a drastic effect on the tires psi.
  8. Thanks for the replies! I do have a set of michelins. 30psi sounds so low. I think I will try out 34psi. If i risk premature and uneven wearing of the tire I would just assume preserve the tire and have a more comfortable ride than save any mpg.
  9. Yes, I thought the same thing. The 2007 RX 400h says HYBRID on the door but its a plain looking silver. I really like the colorful hybrid Camry badge, they should put something similar on the Lexus. :)
  10. Michelin 235/55R18 on my RX 400h. Max PSI is 44, recommended psi is 30 and I currently have them at 38, which is what they were at when I brought the car home from the dealership. I wouldnt mind increasing the psi by 2 or so in an effort to maximize gas mileage.
  11. What is your tire pressure and what tires are you using? Michelin P235/55R18 99V I drove my 400h home from the dealership on friday and checked the pressure, my front tires were 37 & 37.5 psi and my back tires were both at 38. I filled them all up to 38psi. I noticed the max tire pressure on the wall of the tire is 44 and the recommended tire pressure inside the drivers door is 30. Just curious what tires and psi other people are using and how they think it is affecting their mileage. I drove 300 highway miles home and was getting around 22mpg @ 75mph.
