notes for DISTRONIC PLUS (
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you
have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot are
switched to passive. DISTRONIC PLUS
remains active.
