56 OPERATION
WARNING
ACC cannot compensate for excess
speed differences
Risk of accident
ACC cannot perform emergency brak-
ing. The deceleration and buildup of de-
celeration are limited.
The system cannot compensate for sig-
nificant speed differences, e.g. when
quickly approaching a truck ahead or
when another vehicle moves into your
lane.
If the setting range of ACC is exceeded,
objects cannot be detected as quickly
due to the high speed. Therefore,
heightened caution is mandatory.
Observe the traffic and actively inter-
vene in the respective situations.
WARNING
ACC can lose track of detected objects
Risk of accident
When ACC deselects a detected object
erroneously, the motorcycle will accel-
erate to the set speed. This can be the
case when riding around curves, for in-
stance.
Observe the traffic and actively inter-
vene in the respective situations.
WARNING
ACC cannot sufficiently decelerate at
high speeds going around curves
Risk of accident
Curve control reduces the riding speed
if the distance control is active and the
leaning angle is too great. When a ve-
hicle has been detected, the motorcycle
decelerates more slowly when at a lean-
ing angle.
Select an appropriately low speed.
ATTENTION
ACC can misidentify certain objects and
traffic situations
Risk of injury due to unexpected brake
intervention
Certain objects and complex traffic sit-
uations can cause ACC to issue unnec-
essary warnings and decelerate. For in-
stance, a narrowed lane (construction
area) or flying objects (e.g. balls or plas-
tic bags) can result in a warning or a
deceleration being issued by ACC.
Observe the traffic and actively inter-
vene in the respective situations.
When riding in other countries, the
country-specific provisions for oper-
ating radar sensors must be observed. The
radar sensor must be disconnected if ACC
has no radar license for a particular country
and the country-specific provisions require it.

WARNING
Reduced support after switchover to
cruise control
Risk of accident
Unlike ACC, cruise control does not re-
spond to the traffic ahead but adjusts
the speed to the stored value.

vene in the respective situations.
