sur face, the wheels may lose traction. #
Take into account thero ad sur face and
th e dif fere nce between the driving
speed and target speed before activat‐
ing DSR. If
yo ufa ilto adapt your driving style, DSR can
neither reduce therisk of an accident nor over‐

account road, weather or traf fic conditions. DSR
is only an aid. You are responsible for maintain‐
ing a safe dis tance totheve hicle in front, for

st ay ing in lane.
Yo u are alw aysre sponsible forke eping control of
