Tyre pressure light when freezing outside

[CMO]

Hello, 

I got my new UX F sport in October last year, the last few times I’ve driven it when the conditions outside are freezing my tyre pressure light has come on. It goes off later on once it’s warmed up outside. Is this normal? Haven’t had this issue with any other of my Lexus.

Maybe you have one tyre pressure right on the lower limit which is then being reported to the controller . Check your pressures are in the middle of the range they should be

As Nick has said but remember that tyre pressures increase when warm and decreases when cold.

I’ll check my pressure again tomorrow, I’ve never had this issue before. Thank you

It is important that you check,and set the tyre pressures while they are cold, and  not when the car has been driven a distance to warm them up.

Never had the light come on however when ive looked at the reading on the TPMS on start up ive noticed one wheel may be giving a different reading. Then when looking again they all read the same. Temparature differentials will come into play.

I've had this issue regularly on more than one CT. As soon as it's warmed up it's fine
