  1. On a gen3 450h the tyre pressure monitor is displayed as a row of four figures. Does anyone know which figure relates to which wheel? I don't really want to pump up/let down each tyre in turn to find out which is which!!! Any thoughts? JBP

    Alarm problem

    Hi Barrie Does it do it only when parked in certain places as it could be someone else's interference? Ours only did it when parked on our drive - behaved itself everywhere else! JBP

    Alarm problem

    Had a problem with car's remote locking/alarm once that turned out to be a button stuck down on the house alarm remote control. This caused it to continuously transmit which in turn interfered with both our cars parked on the drive. Just a thought! JBP
  4. Hi John It's absolutely sod's law with punctures. It reminds me of when we had a Reliant Scimitar GTE (great car, but that's another story). We had had it for several years with no punctures but then drove down to Les Arcs for a skiing holiday. Halfway down through France the driver of a car behind began flashing his lights and gesticulating pointing to the back of our car. I pulled over to find that one of our rear tyres was half flat and was rapidly deflating. Changed the wheel for the spare tyre. (A great feature of the Scimitar was that the spare was kept under the bonnet in front of the engine so no need to unload all the luggage just to change the wheel!) Carried on to Les Arcs with no further problems and parked in a multi storey carpark. A couple of days later I found a garage in the village that said they could repair the puncture so went to fetch the car only to find the other rear wheel had picked up a nail and was as flat as a pancake! Luckily I had a foot pump so inflated the tyre and drove round to the garage where they repaired both punctures. At the end of the week on the drive home the car's handling started to feel a bit strange. Would you believe a THIRD puncture!!! Not one for years then three in one week!!!!! I do miss that car, though. JBP
  5. Here are some musings I did when we had an RX400h. Just take care as I cannot guarantee the accuracy of the figures and each car is different! JBP
  6. Not only AA cover but cover for travelling abroad as well. JBP
  7. Just got back from a short holiday in and around the Cotswolds with a calculated brim to brim consumption of 34.5 MPG over a distance of 406 miles. As we were nearing home the low fuel light came on with the cruising range showing 26 miles left til empty. Wasn't worried as it was only a few miles to where I was going to fill up. At the filling station the cruising range showed 16 miles to go. It took 53 litres to fill the tank to the brim so there would have been 7 litres left in the tank which would equate to about another 50 miles meaning that when the low fuel light came on there was probably about 60 miles left in the tank. However, as I always say, don't rely on those figures for your own car! JBP
  8. Hi J These were the chains I bought for the 400h. As I said I tried them on the 450h on our driveway at home just to see if they would fit (which they did) but I didn't drive anywhere with them on as there was no snow back in the summer! So please don't take my word as gospel that they will function properly on a 450h. When you get your chains I strongly advise you to practice fitting them at home on a dry, sunny, warm day as I can assure you that on a freezing cold snowy night in pitch black darkness with your fingers numb with cold is not the best time to try to fit them for the first time! Good luck and let us know how you get on. JBP
  9. Hi When we had an RX400h a few years ago we bought a pair of snow chains from Cooks Motor Spares in Chesham. They were very good and served us well on a couple of skiing trips. The chains should be fitted to the front wheels. I have tried Googling Cooks Motor Spares and it appears that the shop is now closed but they seem to be trading through Amazon. You could try this link... https://www.amazon.co.uk/s/ref=nb_sb_noss?url=me%3DA1IK8RDYSZD34I&field-keywords=snow+chains The RX copes very well in the snow generally without chains but don't forget that Newton's laws of motion still apply when driving 2.5 tons of car downhill on a slippery surface!!! See my old post at Good luck! JBP PS We now have an RX450h and the old chains seem to fit this OK (despite the 450h's wheels being 19" diameter but different width/tyre wall height) but I only quickly tried them on on the driveway as a matter of interest to see if they were worth keeping.
  10. Glad it worked for you. Happy New Year! JBP
  11. Although, with a hybrid, low mileage about town probably wouldn't be a problem as the engine management would make sure the engine warms up quickly, even on short journeys. Also, the engine wouldn't necessarily be running all the time anyway and rarely over revved racing away from traffic lights like "ordinary" cars! JBP
  12. Wind direction can make a considerable difference as well. We have noticed driving down through France on a regular 400 mile journey different fuel consumption when outside temperature, speed etc have all been similar but with a north or south wind. JBP
  13. Glad to see you weren't breaking the speed limit, but how did you manage to take the photo? JBP
  14. Hi Chris It might be worth trying the ISC (idle speed control) learning procedure. It certainly worked when we had an RX400h. http://us.lexusownersclub.com/forums/topic/58930-isc-learning-procedure-without-lexus-diagnostic-tester/#comment-379201 Good luck JBP
