Thanks for response. If not depending on temperature conditions external and internal,probably does not work.These questions were put and the representative Lexus Romania but did not receive response(in my country are very few cars of this typ,and not all have this function).If you would be better for me to check if it works at any temperature outside(if you do not,expect winter) Thanks again,Liviu

Hello, sorry for bad english. I have a Lexus IS 220d for which we did not know how works additional heating. I found in user manual only that the additional heating system was activated after 30sec. after pressing the button and in time of 55 sec. heating the inside of the car. I kindly ask you if there are some conditions (external temperature, internal temperature, fan speed) We hope in a fast answer Thank you for your help, Best Regards
