If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor over‐
ride the laws of physics. 4MATIC cannot take
®
and 4ETS,
account of road, weather and traffic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe distance from the
vehicle in front, for vehicle speed, for braking in
good time and for staying in lane.
