W211 Climate

[Adamki83]

Quick question,

As i was cleaning my car i knocked the "rest" button on my climate control and also found i can turn on "auto" while my key is out of the ignition.
Even when i lock the car it will continue to blow a gentle breeze of air through the cabin.
Can anyone tell me what this feature is usually for?
I can only assume its to ventilate the car???

Rest is there to give you basic heating/ventilation whilst sat waiting for the management to come back from whatever errand they’re on.

It will run for ~ 1 hour
