NOTESSpecial notes:
If the opening element motors are supplied too quickly and it is too difficult to test
using a multimeter, the measurements must be made using an oscilloscope.
No faults should be present or stored.
IMPORTANT
The door motors can perform 15 successive activations; beyond this there is a risk of the motors overheating and
being damaged.
NOTESNo faults should be present or stored.
Status ET463 “Door(s) or tailgate” must be “Open” when at least one of the
doors or tailgate is open and must be “Closed” when all of the doors and
tailgate are closed.
Note:
The tailgate lock (electric central door locking) must only be used to open the
luggage compartment and not to close it.
