When the front interior light is on and one of the front doors is open, or when the rear interior light is on and one of the back doors is open, the door sill
lights for the open door will illuminate.
Headlight cleaning system (HCS)
Activating a separate switch causes the EAM to send a turn-on signal to the HCS pump relay.
EAM will send an additional turn-on signal to the HCS pump relay only after the cleaning operation is completed and a "rest period" of approximately
2.5 sec. has passed.
Auto-dimming mirror function
The auto-dimming mirror function is suppressed when the interior light is on or reverse gear is engaged.
Auto-dimming suppression for the outside rearview mirror (slave) is activated by the inside rearview mirror (master).
Heater booster/PTC air heater for diesel engines
EAM monitors system voltage and adjusts heater booster capacity to minimize load on battery.
Rear window defroster
EAM sets maximum ON time for rear window defroster depending on outdoor temperature and current vehicle speed.
-
Standard ON time:
10 min.
-
Outdoor temperature < 5 degrees C: Additional 5 min.
-
Speed >80 km/h:

Ignition authorization via CAN
The EAM issues ignition authorization to AAM2 via the engine compartment CAN depending on the requirements of the engine control unit in
connection with the FBM.
