Does the hybrid ICE have an electric oil pump?

That's why I always breathe through my nose when sitting in a defrosting car, seems to help ;)

Have you checked the cabin air filter?

Seconded, the Harmony remote is a great bit of kit, very versatile. I have it controlling all my AV kit. Even if your device isn't immediately compatible you can 'teach' the remote the basic functions, then send Logitech an email request, they can quickly update their database.

That's the science of it, a cool surface condensing water vapour. But if one operates the a/c there is very little water vapour in the incoming heated air and generally within the vehicle. Parking up overnight there will be a degree of condensation, depending on temperature differences and humidity levels but once the a/c starts up this clears quickly. If condensation is a major problem then one should look to making sure things like scuttle drains are free from blockages (leaves etc..), carpets aren't wet from leaks or overflowing drains. Check also the underneath of the carpets, the sound deadening layers as sometimes the carpet surface is dry but the underfelt is sodden.

I've always kept the a/c on in all my cars, summer and winter. This dehumidifies the incoming air and keeps the interior free of damp and the windows clear. Even says to do so in the owner's handbook. In some systems (not sure about Lexus) it's recommended as it keeps the system seals lubricated, preventing leaks. BTW - I've never seen a negative impact on mpg.

One could also fit this to facilitate oil draining. http://www.fumotousa.com/

You shouldn't have 'sludge' in the sump! Not sure draining would be anymore scavenging than suction, unless you also drop the sump pan? Draining via the sump plug, in many cars, requires the removal of under-trays etc.. The oil filter usually easily (in my Mercedes anyway) accessible from above? Some cars (AMG) need to be drained as they had saddle sumps, so couldn't reach both via the dip tube (which a few didn't have!) but does anyone know, do Lexus dealers drain or pump?

What's the panel's view on oil extraction using a pump as opposed to draining via the sump plug? I know many main dealerships now use suction rather than draining. Certainly makes the process easier for the home mechanic

Lexus simply state to use a mild detergent (as for woollens) and a damp cloth to clean the leather.

|Agree, regarding Gliptone cleaner. I had a full nappa retrim in my Mercedes and had to use the cleaner every week to maintain the finish, which wasn't PU coated. Not something I would have done again, too much upkeep....

Gliptone cleans well and the conditioner imparts a new leather smell, not sure it actually does any conditioning though...

No point as all automotive leathers are PU coated and the conditioner cannot penetrate the surface. You can do the water test, thoroughly clean the leather and place a drop of clean water on the flat surface of the leather. If it is absorbed, conditioning will work. If it simply sits on the surface, no point

My RC300h has been returning a steady 42mpg on my 8 mile urban/town drives

2005 Mercedes CLK 240 ... Rust, rust and more rust....

My experience precisely! I'm still baffled as to why, as you say, the ICE cuts in or not seemingly irrespective of battery level/throttle position. Possibly due to ambient and/or engine temp and a/c requirements? Agree, unless I see the EV indicator the switch between ICE and electric is undetectable. Toyota have refined their hybrid technology very well and Lexus have integrated it well into their cars. 😎

I imagine there is little in the way of extra expense put into the display of the data from a sensor that is pretty much standard in any car with some form of stability control. An amusing gimmick possibly only of interest to someone who uses the car on track.

DPF regenerating?

Handbook has the fuse boxes located in the engine compartment front right-hand side and in the cabin under the glove box

Internal Combustion Engine?

Could it be this? " Sport S mode includes a new G-sensor AI-shift control, which uses information from the vehicle’s G-sensors to select the best gear ratio for high-performance sports driving. The transmission will automatically downshift during hard braking for a corner, hold a lower gear through the corner for greater control, and then select a suitable low gear on corner exit to give the driver greater throttle response.

One has to give the lenses a coating of spray UV protection after polishing to remove the milky bloom, or it just comes back super-quick!

What do you like about the car?

On my Premium Nav equipped RC that icon allows me to change the layout and content of each section on the Home screen. Brightness etc. is a separate menu item in the Setup screen.

I have had my RC300h for just 2 weeks and am loving it 😎 many compliments Curiously the rear access function didn't work on the driver's side either, bit of a coincidence ! Only noticed it a couple of days in when getting the grandchildren loaded. Dealer sorted it very quickly. Apparently it just needed initialising again.
