I am a first-time owner of a used RX350 and am really enjoying the experience. This forum has been a great resource for me and I've done a lot of searches to find answers to my questions.

So, I'm hoping that someone can tell me what it means when my navigation system message reads "TempLo" as I adjust temps up/down. Thanks very much!

 

It will only adjust the temperature within a certain range. You have set as low as it will go when it says "TempLo".

I think the range is 61 degrees to 86 degrees. It will say lo or hi if you try to set the temperature above or below the range.

 

^^ what he said!

 

I used to set my temp to HI or Lo instead of a numerical number.
Your car will get cool or warm pretty fast, but you will touch the dial again to adjust it.
Try playing with the temp and once you get that comfy number, you won't have to bother with the thermostat again.
Mine is 74 during summer and 76 during winter.

 

Thanks All! I really appreciate your help.
