4MATIC ensures that all four wheels are driven
when needed. Toget her with ESP ®

4MATIC impr ovesth e traction of your vehicle

neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. 4MATIC cannot take
account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane. 0009
In wint ryroad conditions, the maximum
