4MATIC ensures that all four wheels are driven.
To get her with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsu1cient traction. Yo
u can display the cur rent distribution of drive
to rque s on all four wheels in the head-up display
and in theright-hand display range of the inst ru-
ment display . The higher there specti vescale is
/lled, the higher the cor responding drive torque
is.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor override

Spinning the wheels results in a cutting
