The heated rear windshield and door mirrors are activated by pressing the switch on the climate control module (CCM) (3/112). The climate control module (CCM) transmits information via the controller area network (CAN) indicating the status of the electrical heating to the following:

• central electronic module (CEM) (4/56)
• driver door module (DDM) (3/126)
• passenger door module (PCM) (3/127).

By starting the rear demist, together with other actions, the vehicle's alternator is loaded and the engine coolant temperature rises.
