3.6.3. Semi-Automatic Alignment System
The most distinctive feature of the Semi-Automatic Alignment system is that it automatically
performs the alignment for only one angle value. For this reason, the Automatic Alignment
function only works when the angle between the truck and the trailer is 0°. It is controlled by
the yellow position lamp that the angle between the truck and the trailer is 0°. The yellow po-
sition lamp illuminates only when the angle between the truck and the trailer is 0°. In cases
where the yellow position lamp is not lit, the Auto Alignment function will not work even if the
“Auto” button of the Remote Control is pressed. To activate the Auto Align function, it is nec-
essary to press the Auto button of the Remote Control by placing the truck in a level position
with respect to the trailer.
3.6.3.1. Signaling of Steering Warning Lights
There are two lamps on the left front of the gooseneck, on the remote control receiver unit,
and on the control panel on the left side of the gooseneck. These lamps are yellow and red
colored LED lamps. The yellow lamp flashes according to the fifth wheel movements and
the red lamp flashes according to the steering axle movements.
Tasks of lamp signaling:
