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 lock ing.
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. Fu
nction of BAS The Brake Assist Sy
stem (BAS) supports your
eme rgency braking situation with additional
brake forc e.
If yo u depress the brake pedal quickl y,BA S is
acti vated:

Cruise control and limiter
Fu
nction of cruise control
Cruise contro lre gulates the speed totheva lue
selec tedby the driver.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can store any speed abo ve20 km/h up to
th e maximum design speed or up tothe set win‐
te r tyre limit.
Obser vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 185).
Me rcedes‑AMG vehicles: cruise control is avail‐
able up toa maximum speed of 250 km/h.
Displ ays on the multifunction display
R h (gre y): cruise contro l is selected but
not yet acti vated.
R h (green): cruise control is active. A
stored speed appears along with theh dis‐
pla y.
% 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 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
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 a short-term speed restriction,
e.g. in built-up areas
R Perm anen t:for a longer-term speed restric‐
tion, e.g. in winter tyre mode
Yo u can store any speed abo ve20 km/h up to
th e maximum design speed or up tothe set win‐
te r tyre limit. You can also per form settings
while theve hicle is stationary if theve hicle has
been star ted.
Obser vethe no tes on driving sy stems and your

Information on the permanent 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 between
16 0 km/h and 240 km/h in the multimedia sys‐
te m (/ page197).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message, display messages no lon‐
ge r appear until you swit choff theve hicle. The
speed will only be displa yed again once theve hi‐
cle has been restar ted or if the set speed is
ch anged.
The permanent limiter does not swit chtopas‐
sive mode even du ring kickdown and the driven
speed remains below the set speed. 19 6
