It is meant to be lifetime but probably worth changing every 100k miles. I've not heard of IS300h transmission issues on these forums - the IS300h has been around for 5 years now so if there are long term issues we will probably start to hear about them around this time.

You can probably do it but it won't make any difference. The stock setup is fine, if you want the ultimate plug performance the use Denso IK20 plugs but it won't really make much difference on the IS200 engine other than placebo.

Only the SE doesn't, all other grades do. Lexus currently doesn't sell a new model without folding seats as the SE has been discontinued.

Which ones? Ones in the US where oil changes intervals are normally 6k at the most anyway. Europe has had change intervals of 10k to 20k for years now with no issues with engine wear, in fact engines are far more reliable now than 20+ years ago when intervals were 6k. Mobil 1 when it first launched stated you could increase your intervals to 20k miles with no issues but as it went against service schedules they had to stop saying it.

Replace the battery. You shouldn't really expect more that 6 years life out of it. Lexus improved this issue with the series III by using one that can handle being deeper discharged.

hmm, they are about the same size, the IS has foldable rear seats and the GS has been discontinued so not great advise

The DVD player under the seat can get damaged by being kicked etc and also the cables may become dislodged so worth taking a look. I think there is a secondary input on these systems, look for a cable inside the rear pocket of the drivers seat. If you can connect something to that and switch input it should confirm that the actual screens are working and the fault is with the player.

I'm not a fan either, makes the finishing look cheap. Unfortunately all the current Lexus SUVs are the same.

No it doesn't mention it because there is nothing to do - no adjustment is needed.

I believe all of the series IV GSs have Xenon and/or LED lights with a flat beam and hence you don't need to do anything. If you press and hold the DISP button on the steering wheel a menu will appear and Units is one of the options where you can select miles or km.

It's fine, although the 4l size is annoying as it isn't enough so you have to purchase two, or an additional expensive 1l.

I think it is still stainless but there are different grades, some of which will corrode well before 20 years.

If it is 10% cheaper than the GS in the UK then it will be under the IS pricing, starting around £32.5k.
