Tom,

Alex, 4 hours of cheap elecricity charges my car to about 80%. I don't do long journeys every day any more, so that suits me fine as 2 nights of charging takes me up to 100% even with daily trips to the local shops. Interestingly, I did a longer journey today and now the weather has warmed up I achieved 48.2 miles on EV alone, up from 39 or 40 miles in the cooler weather.

Alex - thanks for that. The £1,000 odd cost of an Ohme charger would take a long time to recover at a saving of 1.5p per Kwh! I think I'll stick with the good old 13 amp socket. One issue I do have is that the Lexus charging programme cannot be set for both start and stop times, which is needed to make full use of the low cost period. I have overcome this by fitting an external 60 amp timer to the 13 amp supply, which I needed to do anyway because I have a heated pool. The pool does not have its own timer and I needed to heat it during the low cost period as well as charge the car. Tom

Interesting John & Chris. I know that Octopus have a somewhat cheaper tariff than 'Octopus GO' which I am on and gives me 9p per unit from 0030 to 0430. However, my understanding is that the 7.5p tariff is only available for those cars whose manufacturers have signed up to Octopus' clever smart arrangement, which Lexus have not. Chris, I also export excess solar, but am paid 70.71p per Kwh. We were lucky enough to get on original 'feed-in' tariff.

Is that what they charge at public charge stations? A big difference from the 9p per Kwh I'm paying for 'Octopus Go' each night. At my indicated 2.4 mile/Kwh I calculate that 33 miles is costing £1.24. At £1.49/litre for petrol, 33 miles of pure ICE only is costing £6.77, which is 5.5 times more. Even the Octopus daytime rate of 26.778 p/Kwh, it is 1.8 times cheaper than petrol.

David, Mine is in 'ECO' mode and now showing 2.4 mile/Kwh. Note that when in EV mode the car will sometimes make up its own mind to change to HV mode for a short time. I think this may be to keep the 12v battery charged, or perhaps some other reason, but it gives you a false idea of the range you think you are getting in EV mode. I tried a longer motorway trip recently in HV mode, but the car stayed the whole journey with the ICE engine doing the driving and the fully charged EV battery stayed fully charged. So I put it into EV mode for the return journey! Electricity is cheaper than petrol! Tom

p.s. Make sure the dealer properly sets up your second key. Mine did not.

I was given one complete key and one metal key at time of purchase. I was subsequently given one spare key remote only, along with locking wheel bolts.

Does anyone know how to re-set the m/Kwh display? I don't really want to know the overall average, but more interested in how the figure might improve now I'm no using heaters and lights as much.

Bob, Holding the trip button resets whichever trip meter is selected, A or B, but doesn't reset the Miles/Kwh indicator on my car.

Back on the original subject of miles per Kwh - does anyone know how to reset the Miles/Kwh indicator? Mine started at 2.9 when new but gradually dropped back to the current 2.3. Now the winter is over (??) I would like to get an idea what it's doing without heaters, lights etc. Tom

Agreed - but 804 pages is a lot to print out! Perhaps I'll just print the relevant pages.

Thanks again Kevin. I see the owner's manuals are available on-line thus saving £49.80! at https://www.lexus.co.uk/owners/about-my-lexus/manuals The number you gave me looks like it's for the 2022 version of the 450h+. There is a 2023 version : PZ471-9AA96-EN.

Thanks Kevin for explaining that. Now to see if I can obtain the full manual!

Thanks for that Kevin. It does show that my handbook is entirely different to yours though. There does not appear to be any such section in my handbook! Mine has the ID: PZ471-U0142-EN V1 on the back cover. Cheers, Tom

Does anyone know the reason why, when running my RX450h+ on EV only with a full charge, the petrol engine will start and run for a few miles? The Lexus service manager says it's to cool the battery, which I don't believe.
