DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case in enclosed spaces or if
th eve hicle gets stuck in sn ow,fo rex ample. #
Alw ays switch thest ationary heater off
in enclosed spaces without an air
ex traction sy stems, e.g. in garage s. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐
ning. #
Open a window on the windward side of
th eve hicle toensure an adequate sup‐
ply of fresh air. &
WARNING Risk offire due tohot station‐
ary heater components
When thest ationary heater is swit ched on,
parts of theve hicle can become very hot,
e.g. thest ationary heater exhaust sy stem.
Flammable materials such as lea ves, grass or
twigs may ignite if they come into contact
wi th:
R hot parts of thest ationary heater exhaust
sy stem
R theex haust gas itself
There is a risk of fire. #
When thest ationary heater is swit ched
on, make sure that:
R hot vehicle parts do not come into
contact with flammable materials. R
theex haust gas can flow out of the
st ationary heater exhaust pipe
unhindered.
R theex haust gas does not come into
contact with flammable materials. *

ph ysical limits:
R When pulling away on wet or slippe rycar ria‐

R Instro ng side winds when you are driving
fa ster than 75 km/h.
If th eve hicle deviates from the direction desired
by the driver, ESP ®
can stabilise theve hicle by
inter vening in thefo llowing ways:
R One or more wheels are braked.
R The engine output is adap ted according to
th e situation.
ESP ®
is deactivated if theå ESP®

R Driving stability will no lon ger be impr oved. R

th eve hicle/trailer combination is no longer
active.
R Crosswind Assist is no longer active.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.

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.
ETS/4ETS can 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‐

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 limi ter
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 restrictions, e.g. in built-
up areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode. The
variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store
any speed abo ve20 km/h up tothe maximum
speed or up tothe set winter tyre limit. You can
also per form settings while theve hicle is station‐
ary if theve hicle has been star ted.
If yo ufa ilto adapt your driving style, the limiter
can neither reduce therisk of an accident nor
ov erride the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. The
limiter is only an aid. The driver is responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay‐
ing in lane.
Mercedes‑AMG vehicles: the limiter is available
up toa maximum speed of 250 km/h.

Pe rm anent limi ter
If th eve hicle should ne verexc eed a specific
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 toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (/ page 226).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you

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 h,kori, 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. The DSRsymbol appears in
the multifunction display with the
messa geoff. The status indicator in the multi‐
function display disappears. You also hear a
wa rning tone.

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
