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

ARNI NGRisk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced
tyre grip.
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
tread dep thand the condition of the
tread across the entire width of all tyres.
Minimum tread dep thfor:
R Summer ty res: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legall y-prescribed limit forthe
minimum tread dep thisreached. Car
ryout thefo llowing checks on all wheels regu-
lar ly, at least once a month or as required, for
ex ample, prior toa long jou rney or driving o.-
ro ad:
R Check the tyre pressure (/ page 350). R
Visually inspect wheels and tyres for damage.
R Check theva lve caps.
