Introduction
For increased user convenience, an automatic
tailgate is optional in the new Audi A6 Avant ´05. The
automatic opening and closing function is
implemented by two electric motors mounted on
the tailgate hinges. Each electric motor has a step-
up gear, a magnetic coupling, measuring sensors
and an electronic control unit. The tailgate drive on
the driver side (left-hand side) is the system master;
it is connected to the convenience CAN bus. The
tailgate drive on the front passenger side is the
slave.
Automatic opening
Opening of the automatic tailgate can be initiated
by pressing the centre button on the remote control
key, or by pulling the release button on the driver's
door, or by pressing the handle on the tailgate. The
opening cycle can be interrupted by repeating the
initiating operation. Pressing again the centre
button on the remote control key or the tailgate
release button in the driver's door continues the
interrupted opening cycle.
