There are three different audio system in the CT. Standard 6 speaker system with the amp integrated into the headunit. 10 speaker system with separate amp and sub, provided on vehicles with Nav. 13 speaker ML system with separate amp and sub. If you have a standard 6 speaker system then you would need the amp, headunit, sub, sub housing and wiring to upgrade to the 10 speaker OEM system.

You should get 5 years out of the battery provided it isn't repeatedly discharged heavily or left in a semi-discharged state. I swapped out my factory fitted battery when it was around 7.5 years old - I had flattened it a couple of times during the 5 years I had the vehicle and it was definitely down on capacity so I replaced it before it let me down. Covid has certainly helped kill a few batteries in the last 18 months due to people using their vehicles less and batteries not being kept charged up.

They would be illegal here so even if we got the IS500 it wouldn't look like that. I just find the new IS to be too outdated - the interior hasn't changed in 8 years.

I have no issue with the ride, although it may be better with normal tyres. I just find the ones fitted my mine to be extremely noisy.

I've mentioned this before but standards have dropped over the years. When they had the independent RAC inspection it wouldn't pass if there was a single untouched stone chip, tyres needed at least 4 mm tread, unmarked glass etc. Back in 2005: Now it is:

Grades with 18" wheels. I don't really understand why there is a difference; 17" with goo and 18" with runflats. I can only think that Lexus load up the more expensive 18" models with more expensive runflats - personally I'd want 18" with goo.

I wouldn't say you need Yellow ones. Red is suitable for your GS, Green is definitely for smaller vehicles. I used Red on my GS F with stock discs no problem, and whilst the brakes are much bigger than on your vehicle I'm sure Red would be find on the GS300 too. The main reason I changed was to get rid of the squeal that you get with the OEM track pads, which won't be an issue for you, but the dust and price reduction is also nice.

Ethanol has about 30% less energy for the same volume as compared to normal unleaded fuel, and fuel economy is directly related. E10 therefore has 3% less energy than unleaded. The fact that we are already using E5 means there will only be a 1.5% change moving to E10, which for most will be unnoticeable but will be there all the same.

I agree it isn't great but the frequency of update is somewhat determined by the settings on the vehicle - you can set it to connect more frequently with the disadvantage of using more mobile data so the owner has the choice.

I'm quite shocked by this admission John 😉 Firstly your owners manual instructs you to set the parking brake when parking and secondly, it is a legal requirement to do so in the UK if you park on a public road as stated in the Highway Code rule 239:

Personally I use it every time as I don't like the vehicle rocking about when I get in/out of it. If you don't use it then you could fail the MOT because it has seized up.

I've never had a big problem with the interface but there are certainly better systems out there, and I find it is getting worse. The system in my wife's 2020 UX is certainly less intuitive than my 2016 GS and the trackpad is worse than the mouse for me. I don't find them slow, but certainly some of the older generation Lexus systems were. AA/CP gives you choice; if you don't like the in-built system then you aren't stuck with it. Personally I find Apple Maps or Waze better than the Lexus system, and I like the ability to set a route whilst in the house on my phone and just connect up rather than fiddling around entering an address on the Lexus system using the poor trackpad. The real-time updates on google/apple are more real-time than the Lexus system, plus with Waze you get alerts to cameras, broken down cars etc. With CP I'm able to select my source of audio (e.g. Music, Audible, Spotify). Without CP all I can do is select iPhone my the source and then I have to touch the phone to switch between the apps. With Webex I'm able to launch the app in CP and ask Siri to join my next meeting. Lack of integration with HUD is Lexus' fault - they added AA/CP functionality later than most, and BMW and VAG for example provide this functionality now.

After you entered UT, you had 29 matches - if you clicked on 29 it would have listed all of matches for you to narrow down your search. It's a shame it doesn't do that automatically as you type on the same screen.

Ceramic Coatings don't offer any protection against stone chips, they provide UV and stain protection, plus make it easier to clean and provide a high gloss finish. This is all similar to wax but it lasts much longer. They may offer slight protection against swirl marks but this is often overstated. If you want chip protection you need a PPF.

I'd say the reminder software feature is generic and applies across multiple vehicles, some which require ATF changes. Fluid change is part of the maintenance schedule if you are on the severe schedule so is applicable to the IS250. Most dealers don't set/reset those schedule reminders - they are more for the owner's use if they DIY. Dealers use their service schedule, not what the calendar function of the nav system states.

No, they both have perforated leather seats. You can't always see it in low quality jpeg web images, the compression smooths out the detail.

Given you are having problems after a service you are best to return it for them to check their work. I wonder if they just triggered the errors when they did the work and forgot to clear it. However it is unlikely to be an air leak as that would produce lean engine errors rather than rich, and getting both banks at the same time means something common to both. The following are the suggested fault areas associated with those error codes but I'd rule out specific injectors or O2 sensors as you have an issue with both banks. Do you have the freeze frame data associated with the error codes? Mass air flow meter Engine coolant temperature sensor Fuel injector assembly for port injection Fuel injector assembly for direct injection Ignition system Fuel pressure Gas leaks from exhaust system Open or short in air fuel ratio sensor (bank 1, 2 sensor 1) circuit Air fuel ratio sensor (bank 1, 2 sensor 1) ECM Wire harness or connector

Welcome Andy 🙂

That's because that is what it has 😉 Some people post misinformation either through ignorance, making things up to suit their own narrative or to wind people up however the facts are for a Toyota hybrid vehicle, engine power and electric power are combined but with the total system power being less than simply adding the two power sources together at their peak power because they don't produce peak power at the same time and the hybrid transmission and control system limits total power. Numbers slightly vary year to year as tweaks are made for emissions etc. but for a UK supplied IS300h in 2018: max engine power output: 178 bhp max motor power output: 141 bhp max system power output: 220 bhp

I averaged about 47 mpg over 3 years and 20k miles. This was an F Sport which had the 18" wheels, which do impact the mpg, as does the less aerodynamic front bumper of the F Sport. My journeys to/from work were very consistent from one journey to another - if I had a loan vehicle, which was typically a grade with 17" wheels, then I would see about 5 mpg improvement over my own vehicle. You can click on the IS300 pic on my signature to see the fuelly stats (make sure you set the units to UK). You need to adapt your driving to get the best economy out of a hybrid - an obviously statement for any type of vehicle but especially so for a hybrid, so your economy improves over time as your adapt. Winter has a bigger impact than you would expect to see with a normal petrol vehicle.

It does look like a loom rather than just an individual wire or sensor, but the loom shouldn't be thick there as it is and the end of the run just to the left of the L grille badge - unfortunately the photo lacks enough detail to be sure. Maybe it is part of the loom that runs along the bottom of the bumper (82113) that has been pulled up ?

If it is actually blocked then typically you would need to replace it - certainly that is the case if it has broken down, or parts of it damaged by unburnt fuel, igniting in the cat and melting it. Proper confirmation needs a camera inserted into the exhaust to look at the honeycomb, or the cat removed and inspected, to confirm. You would also want to make sure the reason why it failed is understood and resolved.

It means air cannot efficiently pass through the cat because the honeycomb is blocked up, either by carbon deposits or because pieces of the catalytic material have broken off and blocked it. It isn't something that is common on Lexus vehicles, especially if the engine is running correctly. The IS200 could suffer from this but normally only when fitted with a supercharger which raised the exhaust gas temperatures, damaging the cat and causing it to break up.

No, the tilt detection of the alarm actually uses the existing ABS/VSC yaw rate/acceleration sensor which is located inside the cabin. Normally when cats are being stolen the wiring to the horns are cut to stop the alarm sounding. The horn on the RHS of the vehicle has a blue wire, the one of the left uses a black one.
