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.

BTW I use 'Octopus GO' via a simple 13 amp socket. This gives me a tariff of 9p per Kwh between the hours of 0030 and 0430. This 3 Kw max charge rate gives me about 80% charge in one 4 hour night's session. If I don't use the car the next day it will set the next charge period for one week's time, thus prolonging battery life by not fully charging. If I do use it the next day, it will top up the next night. All clever stuff!

When you unlock the car to retrieve something, are you pushing the 'Start' button? If so, when you stop the engine you will be invited to 'Charge Now?' You push the top, left hand steering wheel button to do so. Maybe that's the simplest routine.

In the light of all the worries about Lexus RX theft, has any bright spark on this forum come up with any ideas on fitting a hidden switch to disable the car starting? Bit like the switch I fitted to my Ford Thames 100E van about 63 years ago, which cut the supply to the distributor contacts. Yes, I know my RX450h+ is a slightly different beast! Tom

I have to say that the Lexus dealer in Exeter, Snows, treated me very differently from John's experience. Second key handed over along with locking wheel bolts fitted, coffee and biscuits for me the missus and the dog and a nice chat with the charming receptionist! Made arrangement to have the CANBUS theft protection plate fitted, but in the event it transpired that this was already taken care of during manufacture.

I have just collected a spare key and locking wheel bolts for my 5 month old RX450h+, at last! Also I was told that my car does not need anti-theft CANBUS protection plates fitted as this has been taken care of during manufacture. Let's hope the insurance companys take account of this.

I'm going into my dealer next week to pick up my spare key (at last!). I will ask about this weird speed limit behaviour. Tom

Mine showed 2.8 m/kWh when I first got the car back in October. This has gradually dropped and now shows 2.2m/kWh which I put down to the winter use of lights, heaters etc. I would like to know how to reset this display. I get an indicated 40/41 miles range in EV mode. My mostly short journeys are always in EV mode with the occasional longer one in hybrid, so the indicated fuel economy is 99.9mpg which doesn't really help.

On a half mile section of country road my RX450h+ always bleeps and shows 20mph limit. This always happens in exactly the same place and reverts back to 60mph after about half a mile in exactly the same place. This is a country road with no speed limit signs or road signs of any description, just lots of trees. The only explanation I can think of is that the sat nav is telling the car to show 20mph at that location. Does anyone have any ideas? Tom

My Lexus app allows me to remotely set up the heating in the car, which is rather nice in this cold weather, but it won't let me remotely start the vehicle. Why would you want to do this?

I haven't managed to turn off the 9 'beeps' either. But to be honest it doesn't bother me. The 'Deep Dive' tutorials by the lady in Texas are really good but there is a helluva lot of information to absorb!

I won't comment on the dashcam because mine is an old one and this is the third RX it's been fitted to. It's a single forward facing one and was dead easy to fit. The thin 12v wire can easily be concealed behind the windscreen edge rubbers with the aid of a wooden ruler, round behind the inners of the glove box and the plug goes nicely into the cigar lighter socket under the sliding lid compartment. As regards Air Tags,I have fitted one to my single key that Lexus have provided me with as I am paranoid about losing it. Regardless of the non-availability of integrated circuits, I do not think Lexus should be supplying cars with just one key.

Thanks Kevin. Yes, someone else mentioned that it is a warning that you might have left something or someone in passenger seat. I've seen that prompt when I stop the car and wondered what it was! The beeping is not a problem anyway. Cheers, Tom

Strangely and for no apparent reason, it is now working and I didn't do anything!

Well it was there when I collected the vehicle and working fine. Now all I get is a blank screen. I must have dis-connected it or something in the car.

The Lexus App, which was set up when I bought the vehicle and have found most useful, has disappeared from my iPhone 6S. Does anyone have any ideas?
