TIC
The 0exible all-wheel distribution of the 4MATIC
means the drive is alw ays ideal lydist ributed
between bo thaxles. Depending on the situation,
only the front axle or only there ar axle can be
driven, or the drive can be distributed continu-
ously between bo thaxles.
This means that recuperation can be used even
more e.ectively and thera nge of theve hicle can
be increased (/ page 155).
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.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor override
th e la wsof ph ysics. It cannot take into account
ro ad, weather or tra1c conditions. 4MATIC is only
an aid. You are responsible especially for main-
ta ining a safe distance from theve hicle in front, fo
rve hicle speed, for braking in good time and for
st ay ing in lane.
% In wintry road conditions, the maximum e.ect
of the 0exible all-wheel distribution can be
achie ved only if you use winter tyres (M+S
tyres), with snow chains if necessar y. Char

If th eve hicle should ne verex ceed a speci/c
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
Yo u do this by limiting the speed between
160 km/h and 240 km/h in the multimedia sys-
te m (/ page 199).
If yo u limit the speed toava lue abo vetheve hi-
cle's maximum speed which can be driven or

has no e.ect.
Shortly before the set speed is reached, it
appears in the Instrument Displa y.When you con-

appear until you switch o. theve hicle. The speed
will only be displ ayed again once theve hicle has
been restar ted or if the set speed is changed.

The speed (from 20 km/h) and the distance to

insu1cient tyre tread
Insu1cient tyre tread will result in reduced

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

ARNING Risk of accident with high per-
fo rm ance tyres
The special tyre tread in combination with the
optimised tyre compound means that therisk of skidding and
hydroplaning on wetro ads is
increased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your driv-
ing style accordingl y. #
Use i M+S tyres at outside temp era-
tures of less than 10 °C. #

R Furthermore, the use of cer tain tyre types in
