So you are referring to CarPlay? No, you cannot have a mixture of CarPlay and the Lexus system on the screen at the same time. As you have found you can have the CarPlay Home Screen which will show maps and music controls rather than maps being the full screen.

What size screen do you have? I cannot find a way not to have the map on the Home Screen, which is annoying when I'm not using navigation, so I'm surprised you don't have it.

Definitely worth doing IMO.

The UX doesn't seem to like being put in EV drive mode, unlike older Toyota/Lexus hybrids, as it seems to nearly always be unavailable. What I have found though it that the vehicle doesn't just automatically start the petrol engine after a few seconds after it is put in Ready mode like older hybrids so there isn't a real need for EV drive mode anyway when all it is really meant for is to allow you do move the vehicle out of a garage without causing exhaust fumes which the UX will do anyway. Seems to be by design but maybe there will be a firmware update at some point. Worth mentioning it to your dealer at next service - the more feedback Lexus get the more they may improve it.

Michelin Pilot Sport 4S would be the best but completely overkill for an RC300h - better suited for the RC F. The RC300h rolls off the factory floor with the following wheel options (depending on grade and destination country): 225/50R17 with 17 X 7 1/2J inset 45mm rims 235/45R18 with 18 X 8J inset 45mm rims 235/40R19 / 265/35R19 with 19 X 8J inset 45mm / 19 X 9J inset 60mm rims any of those will keep the speedo within tolerance. For winter tyres you normally want a narrower width so the 17" would be the way to go. If you wanted all-season tyres then the 18" would be a good compromise, although you could just use 235/40R19 front and back.

They have to use super unleaded. Probably ok but no official data to confirm 😞

No and no but it might just be brakes rubbing a little due to lack of use. Just do three or four hard brakes from 50 to 10 mph to clean them up and if it still occurs then ask your dealer to investigate.

But they aren't an all-season tyre. They may be good in the wet but they will lose performance as temperatures get into lower single digits.

Michelin Cross Climate+ are great all season tyres but I don't think they do them in the size needed for the rear of the RC F-Sport. I think you may need to go with summer tyres and a set of winter wheels/tyres.

But the point is it isn't lower - the front /40 and rear /35 are the same (or as close as you can get with the limited tyre size options).

It has had some serious money spent on quality items. Not sure they will get £23k for it though - very limited market so could take some time to sell. The series II/III GS chassis isn't great so it is good to see a lot of effort spent on bracing the hell out of it.

Definitely the high pressure fuel rails. Not sure about the injectors. Also there was a change to the fuel pump in the tank.

You have to remember that the person who came up with the tyre measurement standard was an idiot and made the width figure an absolute measurement but the profile figure a percentage. On the front you have 235/40 tyres and the 235 means 235 mm width which makes perfect sense. The /40 however, which is the height (profile) figure, doesn't mean 40 mm as most people think; it is 40% of the width of the tyre. So for a 235/40 tyres the profile is actually 94 mm. Lexus wanted a wider tyre on the rear so went with 265 mm. This is mainly looks, and to match the RC350 (the RC300h doesn't produce enough power to really need that extra width). If they went with 265/40 the profile would be 106 mm and the wheel/tyre would be noticeably larger. So to keep it the same the matching size is 265/35 which has a profile of approx 93 mm.

That's the cut over year. The series II RX300 looks almost the same as the RX400h. You don't see too many series I vehicles on the road these days:

The problem is that Toyota/Lexus have only issued guidance for European sold vehicles built in 1998 or newer. I've seen lists in other parts of the world that go back further and suggest the LS is fine, but I've also seen vehicles that aren't fine in other parts of the world but are ok on the European list so difficult to have true confidence. I'd make an educated guess that you would be fine with E10. You shouldn't get burnt valves as the closed loop fuel injection system should compensate - that is an issue for cars with carbs. You shouldn't have an issue with extra moisture causing corrosion as the suppliers are meant to be controlling that. You shouldn't have an issue with specific grade aluminium corrosion that affects early direct injection engines as you don't have that. so the risk is possibly just seals (which are very likely to be fine) or longer term damage. E85 is probably something to avoid though. That is much more likely to react to the fuel system and due to the lack of energy compared to normal petrol you would probably need to have the vehicle modified to compensate and maybe even have to fit larger injectors.

Possibly this: 67765A COVER, BACK DOOR SERVICE HOLE, NO.1 67765-76010-C0 BLACK, TRIM0* https://lexus.7zap.com/en/eu/lexus+ct/232510/zwa10r-ahxbbw/3/6708/676688/#67765A

It uses a Toyota Europe backend so all European countries should use it - whether they all do, or if all dealers do, I don't know but I would have thought that Toyota would require all warranty work is logged on their central tool so dealers must have access.

They normally will do a service if it is due within 3 months. What is the date/mileage of the last service in the service book/My Lexus online state? It's possible they just forgot to reset the on-vehicle reminder.

There are normally two; one for the vehicle and another for the sat nav/infotainment system. Sometimes there are multiple car manuals as you may find one for some engine types and another one for the others - and you don't know until you download and look as the model on the bottom left of the first page. You shouldn't really see multiple vehicle ones for the UX as they only sell a single engine hybrid variant in the UK but you will unfortunately - one for the UX200 and the other for the UX250h (the one you want).

Normally no, but it depends on the case and how thick it is, which may make the charging slow, intermittent or just not work.

eHybrid are good. Toyota themselves often discount some of their products on eBay. Snows group are also on eBay and some of their listed items have a discount from list price. You may find getting parts from different suppliers on eBay actually cheaper than a kit. The last time I purchased some items for my son's Yaris I got the air filter/gearbox oil/coolant/pollen filter from eHybrid and plugs/oil filter from Snows

Unfortunately yes. The first few Toyota direct injection engines were direct only (D4), they then moved over to port & direct (D4-S). The IS250 and series III GS300 are both D4 direct only engines.

The IS250 only has direct injection. Therefore it doesn't matter what fuel you use, none of it will wash over the intake valves to stop carbon build-up.

In a word, yes. BHP produced is different according to engine speed. The following from a modern F engine for example shows a peak around 7k rpm. You rev just beyond that before changing gear so that you don't drop too far back. The beauty of the CVT on a hybrid is that it can hold the engine at the peak power rpm so you continuously have maximum power. Most of the time however you don't need all the power the engine can provide so you can just sit at a lower rpm. Put your foot to the floor in an IS300h and it will hold the rpm at 6,000 rpm which is the peak power point for that engine.

The IS is lighter, although not that much. The GS figure you have is wrong because that is the kerb weight, the gross is 2,265 Kg.
