4MATIC ensu resth at 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 instru- 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
th e la wsof ph ysics. 4MATIC cannot take account
of road, weather and tra1c conditions. 4MATIC is
only an aid. You are responsible especially for
maintaining a safe distance from theve hicle in
front, forve hicle speed, for braking in good time
and for st aying in lane.
% In wintry road conditions, the maximum e.ect
of 4MATIC can be achie ved only if you use
winter tyres (M+S tyres), with snow chains if
necessar y. R R

If yo u depress the brake pedal quickl y,BAS is
activated:
