If you are urgent to use the car, please open the door and windows to let out the ozone inside, but if you are not so urgent, you can wait until the ozone changes into oxygen.

All these operation stated above is for disinfecting and sterilizing the carriage and air condition completely, but if you only want to kill the bad smell and sterilizing the carriage, you don’t have to start the engine if there is enough electric in the battery cell. Though the air cleaner will only consume little electric, it will still affect the restart of the engine if you use it for too long time.
