If th eve hicle is tr avelling at speeds of more than

can also switch off the hazard warning lights
using the hazard warning button. Cruise control and limiter
Fu
nction of cruise control
Cruise cont rolre 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 accelera tor pedal af terov ertaking,
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.

speed are shown in the multifunction displa y. Driving and pa

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 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 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.
