nction of ABS The Anti-lock Brake Sy
stem (ABS) regulates the
brake pressure in critical driving 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.

Off-road ABS is activated automatically when
you select theF drive program.
Off-road ABS is specially adap tedfo r driving off-
ro ad:
R The front wheels lock cyclically during brak‐
ing.
R The braking dis tance is sho rtened due tothe
digging-in ef fect.

R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting

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 ew ay. If
yo u select theF drive prog ram, a special
ETS sy stem specifically suited tooff-road terrain
is automatically activated.
ETS/4E TScan impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
th ey spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive prog rams enable ESP ®
to adapt todif‐
fe re nt we ather and road conditions as well as
th e driver's prefer red driving style. You can
select the drive prog rams using theDY NA MIC
SELECT switch (/ page190). Driving and parking

cruise control will
resume speed regulation back
to thestored speed.
Cruise contro l is operated using the cor respond‐
ing steering wheel buttons. You can store any
speed abo 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. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.
Mercedes‑AMG vehicles: cruise control is avail‐
able up toa maximum speed of 250 km/h.
Displ ays in the multifunction display
The status of cruise control and thestored
speed are shown in the multifunction displa y. 1

th e set winter tyre limit, light up in the
speedome ter.
Sy stem limits
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
Plug-in hybrid: obser vethe no tes in the Supple‐
ment. You could otherwise failto recognise dan‐

DSR (Downhill Speed
Regulation) Fu
nction of DSR (Downhill Speed Regulation)
DSR is an aid toassist you when driving down‐
hill. It keeps the speed of tr avel at the selected
ta rget speed. The steeper the downhill gradient,
th e greater the DSR braking ef fect on theve hi‐
cle. On flat stre tches of road and uphill gradi‐
ents, the DSR brakes theve hicle minimally or
not at all.
When DSR is activated and the transmission is in
position 005B,005Eor005C, DSR controls the driving
speed. The target speed can be set toava lue
between 2 km/h and 18km/h. By braking or
accele rating, you can drive at a higher or lo wer
speed than theta rget speed at any time.
DSR is deactivated automatically if you drive at
speeds greater than 45 km/h or select drive
program CorB. The îoffmessage
th en appears in the multifunction displa y.The
st atus indicator in the multifunction display dis‐
appears. You also hear a warning tone. In

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 negotiated. 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 also apply the brakes yourself if requ ired.
Ac tivating/deactivating DSR (vehicles with
E- Ac tive Body Control)
Re quirements:
R You are driving at 40 km/h or slo wer.

Fu nction of reco very mode &
WARNING Risk of inju rydue totheve hi‐
cle moving up and down
When free driving mode is activated, the
ve hicle bounces up and down. Body parts
could become trapped if they are between
th eve hicle body and the tyres or underneath
th eve hicle. #
Make sure that nobody is under or in
th e immediate vicinity of theve hicle

may be damaged if the underbody bottoms
out. #
Make sure that there is suf ficient
ground clearance when rocking free
mode is activated. Ro
cking free 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 reco very 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 259). Fu
nction of individual wheel control &
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
