TIC
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.
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

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 222).
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.

Ac tive Distance Assist DISTRONIC maintains the
set speed on free-0owing roads. If vehicles in
front are de tected, the set distance is maintained,
if necessar y,until theve hicle comes toa halt. The
ve hicle accelerates or brakes depending on the
distance totheve hicle in front and the set speed.
The speed (in thera nge between 20 km/h and
210 km/h) and the distance totheve hicle in front
are set and sa ved on the steering wheel.
Other features of Active Distance Assist
DISTRONIC:
R Adjusts the driving style depending on the
selected drive prog ram (fuel-saving, comfor ta-
ble or dynamic) (/ page 181) R
Reacts tostationa ryvehicles de tected in
urban speed ranges (e xcept bicycles and

R Initiates acceleration tothe stored speed if the

R Take s one-sided overtaking restrictions into
account on mo torw ays or on multi-lane roads
with separate car riag ewa ys(countr y-depend-
ent)
If th eve hicle has been braked toa standstill on
multi-lane, separate car riag ewa ysby Active Dis-
ta nce Assist DISTRONIC, it can automatically fol-
low theve hicle in front when driving o. again
within 30 seconds. If a critical situation is de tec-
te d when driving o., a visual and acoustic warning
is given indicating that the driver must now take
cont rol of theve hicle. The vehicle is not acceler-
ated any fu rther.

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

WARNING
ARNING Risk of accident with high per-

There is an increased risk of skidding and
aquaplaning when using sport tyres on wet
ro ads. In addition,
the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
