4MATIC ensu resth at all four wheels are driven.
To ge ther with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsu1cient traction.
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

ARNI NGRisk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced

The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi-
cle is not adap tedto suit the conditions. #
Thus, you should regula rly ch eck the
