Thanks for all the responses. I will make a thorough search tomorrow. If I find it I will take a photo and post it. I can't be the only one who needs a map to find this. I did check the manual but that was worse than useless.
Thanks for the response but I must be blind because I can't see any nipple. It's not the end of the world if it's not fitted but you would think Lexus would make something like this more obvious. I will search again, tomorrow.
I have a 65 plate f sport acquired in May. I assumed the car had TPMS because I understood it was "standard". I have searched everywhere underneath the steering wheel and down towards the pedals but can't see (or feel) any button to reset it (just checked tyre pressures and wanted to make sure the system was reset). Is it possible it is not fitted on my car?
