In trailer operation, normal mode must
always be selected and care must be
taken that the system is switched to
manual mode (e.g. no automatic
switching to manual mode if trailer
operation signal fails).
In difficult driving conditions, high
level 1 or high level 2 can be selected,
however, normal level must be selected
before a driving speed of 35 km/h is
exceeded.
Driving at low level or in automatic
mode is not permitted.
Trailer operation
The correct position of the tow bar on the
trailer attachment during trailer operation is
indicated in normal mode.
Contact switch F216 in the 13 pin trailer
socket is used to signal that the trailer plug is
inserted, i.e. indicates trailer operation (see
description “Trailer operation signal”.
If trailer operation is recognised, the manual
mode is automatically activated (LED “man”
lights up) whereby the automatic raising
process is stopped.
Normal level is set by the driver via control
unit E281.
