  1. It turns out I was wrong. Further investigation shows that on the IS you can rev the engine while in Park and in any mode (Eco, Normal, Sport). The accelerator pedal is misleading because it doesn't react as a conventional car would when you begin to press it. So although a fairly light touch will get the car moving in Drive, nothing happens for the same amount of pressure when you're in Park. But when you press it a bit further the engine will rev. I don't know if there's a limit to how fast you can rev the engine; I didn't press it very far. But I noticed something else that's interesting. With the car in Park and without touching the accelerator, the graphic displays show that the engine is charging the hybrid battery. But if you rev the engine, it stops charging the hybrid battery, according to the graphic displays. If this accurately represents what is going on, I imagine Motor Generator 1 (MG1) is allowed to spin freely without any load because with the car and MG2 stationary, it could damage MG1 if it was spinning faster than its generating capacity allowed. Or maybe there's some other reason. Either way, it looks as though on the IS the generation stops when you rev the engine and the car is in Park..
  2. It may work differently on different models. On the IS I have the impression that in Normal mode the accelerator is disabled in Park whether you have your foot on the brake or not. That's to say, you can't rev the engine while the car is stationary in Park. But just a couple of days ago I discovered that you can rev the engine in Park when you select Sport mode. Not really my area of expertise, but I imagine this is important for people who like racing the adjacent car away from the lights and you need to blip the engine menacingly while the lights are still red.
  3. Hadn't thought of doing this. Does it make a difference being in Drive rather than Park? If the engine is running, doesn't it charge the hybrid battery while it's in Park as well?
  4. And here he is 54 years ago. Hard to believe! Featuring the up and coming Eric Clapton.
  5. Here's a link to a pdf version of the SatNav manual for the IS from August 2015. I found this on the manuals section on the Lexus website at this address https://www.lexus.co.uk/owners/about-my-lexus/manuals/#hero
  6. Maybe that's what the police press office means when they talk about "key cloning". I understand how relaying the key signal works - I always turn off my key overnight so that my car can't be stolen like that. I thought "key cloning" was like in this video This allows you to actually make a new key from an original. That's what I thought cloning meant. Maybe the police mean "relaying" the signal, which isn't quite the same. The story also talks about using a "skeleton key" to start the car. What's that about? That sounds like the cloned transponder. A skeleton key is usually a universal kind of key that can be used in any lock. But I don't understand how you can have a skeleton universal transponder. I hope someone can explain this.
  7. There's a story here about key cloning gang members being arrested But I don't understand how the cars are stolen. Does anyone have any ideas? When they say "key cloning" I thought this could only be done if you actually have available the original key. But the number of thefts is so great that it seems unlikely that the thieves would have had access to the actual keys of the cars, made a transponder clone and then stolen the car later. Or maybe they did. Perhaps they took possession of the keys briefly in a car park, for example. Anyone have any ideas on how these thefts were done? The newspaper report doesn't explain it clearly.
  8. That sounds pretty good. If your car is 2014 then it looks like a lot of motorway miles - around 24,000 miles a year. So maybe there's something in the theory that there's less demand on the tpms batteries at sustained speeds. I had an early calculator from the 1970s whose battery was still working after over 40 years. So depending on the type of battery perhaps there's no reason to expect them to fail very quickly. Maybe there haven't been any failures on the current IS model as no-one has said they've needed to replace them yet. I suppose they're standard Toyota sensors.
  9. I've been trying to find out how long the batteries should last in the tyre valve sensors for the Tyre Pressure Monitoring System (TPMS). I've seen various suggestions on the internet; five to 10 years, up to around 100,000 miles. I've also read that motorway use at constant speeds makes less use of the sensors than stop-start town driving, so the batteries last longer with a lot of motorway driving. Has anyone had to replace the batteries and if so how old were they (the battery, not the driver) when they needed replacing?
  10. I don't often look at the Lexus "My Lexus" webpage but I did today to see if a recent service had been correctly entered. Not only was the recent service not listed but a lot of the previous service history had disappeared. Some of what remained looked as though it been made up by a panicking data operative. There's a minor service labelled as a major service. There's a service recorded one month, followed by a hybrid check recorded for the following month but bizarrely at about 10,000 miles earlier. Has anyone else noticed that their car's service record has disappeared from the My Lexus website? I did wonder if I was looking in the wrong place - it's not the easiest of websites to navigate. But the fact that some services are recorded suggests that I'm looking at the right page but all the earlier records have disappeared.
  11. The price also apparently varies according to how long before renewal you get a quote. Moneysavingexpert did a review and found that the cheapest quote was 24 days before renewal. The best range of quotes was between 26 and 20 days before renewal.Too close to renewal the price goes up, presumably because they think that the customer is less organised and therefore perhaps a worse risk. Or perhaps they just think they can charge more because the customer is in more of a hurry to take out insurance. Why they charge more for someone who gets a quote a month in advance I can't imagine.
  12. Are you thinking of the Cat Stevens song "The First Cut is the Deepest"?
  13. Yet another vote for Michelin Cross-Climate. They seem nice and quiet, though I haven't had any other tyres to compare. I've driven another, newer, IS300h with different tyres - possibly Bridgestone - and I think the Cross-Climate was more comfortable and quieter. The thing that has impressed me is how little they wear. They're down about 1-2mm in 15,000 miles. I think they've done around 30,000 miles so far, (though I can't be certain because they were on the car when I bought it) and they still have 4mm on the back and 5mm on the front. At that rate, they should last around another 10,000 on the back and maybe even 15-20,000 on the front before they need changing at around 3mm.
  14. Did changing the tyres have any effect? Was it better or worse with new tyres? Did you change the brand of tyre? Maybe some brands of tyre make the GS more stable than others.
  15. I expect most people know this but I'll just add that wiping the mist off the windscreen doesn't help. It's best if the glass is as clean as possible. Then the demister with aircon running should have no difficulty clearing the mist. But if you wipe it with your hand or a gloved hand it will transfer particles of grease and dust onto the screen. This gives the mist something to stick to, making it harder for the demister to clear the screen. I've always found that keeping the screen as clean as possible and then avoiding touching it is best for keeping the screen clear.
