For some reason, some persons were taught to return their heater/AC controls to OFF before shutting down the car. I have never done that and never had any problems.
On every <auto> climate control car I have owned including this one, I simply set it and forget it, likewise. Never have had a problem. Auto control is designed to maintain whatever temperature you want -- this one now has two such controls in front.
By leaving the system on, the compressor runs as needed, when needed, and heat is blended into the system likewise when needed. This also keeps the refrigerant circulating and the compressor seals functioning. This LX also provides the driver with either high or low auto air circulation; difference, accoring to the manual, is that the latter should be used normally with the former used primarly when carrying back seat passengers, also.
In the past 3 LH bodies, there was never climate failure; nor do I expect one on this LX car. It just never gets turned off; just adjust the temperature level as needed.
