nction of ABS (Anti-lock Braking Sy stem) ABS
regulates the brake pressure in critical driv‐
ing situations:
R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr eve nted from lo cking.
R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
Sy stem limitations
R ABS is active from speeds of appr ox.
8 km/h.

R Onlydepress the accelera tor pedal as far as
is necessar y. Deactivate ESP

in thefo llowing situations to
impr ove traction:
R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting
action which pr ovides better grip.

ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP ®
and
makes it possible topull away and accelerate on
a slippe rycar riag ewa y. If
yo u select drive program ForG, a spe‐
cial ETS sy stem specifically suited tooff-road
te rrain is automatically activated.
ETS/4E TScan impr oveth eve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive programs enable ESP ®
to adapt todif‐
fe re nt we ather and road conditions as well as

ve20 km/h up tothe maximum speed
or up tothe set winter tyre limit.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo r maintaining a safe dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.
Displa yson the multifunction display
The status of cruise control and thestored
speed are shown in the multifunction displa y. 1
Cruise cont rol is selec ted
2 Speed is sa ved, cruise control is deactivated
3 Speed is sa ved, cruise control is activated
% The segments extending from the cur rent
st ored speed tothe end of the scale, or to
th e set winter tyre limit, light up in the
speedome ter.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular no
te ofthis when driving a laden vehicle. By
doing so, you will make use of the engine's brak‐
ing ef fect. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode. 228

Information on DSR
&
WARNING Risk of skidding and having
an accident when DSR is acti vated on
slippery road sur faces
If th e speed driven and theta rget speed dif‐
fe r, and you activate DSR on a slippery road
sur face, the wheels may lose traction. #
Take into account thero ad sur face and
th e dif fere nce between the driving
speed and target speed before activat‐
ing DSR. If
yo ufa ilto adapt your driving style, DSR can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. DSR
is only an aid. You are responsible for maintain‐
ing a safe dis tance totheve hicle in front, for
ve hicle speed, for braking in good time and for
st ay ing in lane.
Yo u are alw aysre sponsible forke eping control of
th eve hicle and for assessing whe ther the down‐
hill gradient can be managed. Depending on
ro ad sur face and tyres, DSR may not al ways be able
tokeep totheta rget speed. Select a target
speed suitable forth e environmen tal conditions
and when necessar y,also apply the brakes.
Ac tivating/deactivating DSR
Re quirements:
R You are driving at 40 km/h or slo wer.
If th e cur rent vehicle speed is too high, the
Max. speed 40 km/h message appears in
th e multifunction displa y.
R Active Dis tance Assi stDISTRONIC is deacti‐
va ted. #
Toactivate: pullrock er switch 1.

The DSR symbol will appear on the multifunc‐
tion displa y. #

#
Make sure that there is suf ficient
ground clearance when free driving
mode is acti vated. Fr
ee driving mode is a function of the suspen‐
sion which can assist the driver on loose sur fa‐
ces (e.g. sand, snow) when freeing a vehicle
which has become stuc k.
The vehicle body rock s in slo w,vertical motions
when free driving mode has been activated. This
te mp orarily puts the wheels under greater load,
which means they have inc reased traction and
th eve hicle is freed.
Yo u can activate free driving mode via Off- road
Assist (→ page 262).
Individual wheel cont rol&
WARNING Risk of becoming trapped
due totheve hicle lo wering
The vehicle can be lo wered when the individ‐
ual wheel control function has been activa‐
te d. Body parts could become trapped if they
are between theve hicle body and the tyres
or underneath theve hicle. #
Make sure that nobody is under the
ve hicle or in the immediate vicinity of
th e wheel ar ches when individual wheel
control is activated. *
NO
TERisk of dama gedue totheve hicle
moving up and down The
vehicle can be lo wered or raised on one
or more wheels when the individual wheel
control function has been activated. Vehicle
parts could be damaged due tocontact wi th
objects. #
Make sure that theve hicle has suf fi‐
cient room tomo vewhen the individual
wheel control function has been activa‐
te d. Individual wheel control is a function of
the sus‐
pension which can be used toset theve hicle
le ve lfo r each wheel individually. This can help to
impr ove alignment of the body when driving off-
ro ad.
Yo u can activate individual wheel cont rol via Off-
ro ad Assist (→ page 262). Setting
theve hicle le vel &
WARNING Risk of accident because
ve hicle le vel is too high
If yo u drive at a higher vehicle le vel,th e driv‐
ing characteristics may be impaired due to
th e higher vehicle centre of gravity.
The vehicle can drift outwards, forex ample,
when steering or cornering. #
Alw aysch oose a vehicle le vel which is
suited tothe driving style and thero ad
sur face conditions. &
WARNING Risk of entrapment from vehi‐
cle lo wering
When lo wering theve hicle, other people
could become trapped if their limbs are
between theve hicle body and the tyres or
underneath theve hicle. #
Make sure no one is underneath the
ve hicle or in the immediate vicinity of
th e wheel ar ches when you lo werthe
