WARNING Risk of accident when the low
beam is switched off in poor visibility
When the light switch is set toÃ, the low
beam may not be switched on automatically
if th ere is fog, snow or other causes of poor
visibility such as spr ay.
#In such cases, turn the light switch to
L.
The automatic driving lights are only an aid. You

Cornering light
Cornering light function
Cornering light improvesth e illumination of the
ro adw ayove r a wide angle in the turning direc‐
tion, enabling better visibility on tight bends, for
ex ample. It can only be activated whenthe low
beam is switched on.
The function is active:
RAt speeds below 25 mph (40 km/h) when
th e turn signal light is switched on or the
st eering wheel is turned.
RAt speeds between 25 mph (40 km/h) and
45 mph (70 km/h) when thesteering wheel
is turned.
Ad aptive Highbeam Assist
Function of Adaptive Highbeam Assist
&
WARNING Risk of accident despite
Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recog‐
nize thefo llowing road users:
RRo ad users without lights, e.g. pedes‐
trians
RRo ad users with poor lighting, e.g.
cyclists
RRo ad users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist may failto recognize other road users
with their own lighting, or may recognize
th em too late.
In these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users.
#Alw ays obser vethe tra ffic carefully and
switch off the high beam in good time.
Sy stem limitations
Ad aptive Highbeam Assist cannot take into
account road, weather or traf fic conditions.
De tection may be restricted if:
RVi sibility is impaired, forex ample in fog,
heavy rain or sno w.
RThere is dirt on the sensors or the sensors
are obscured.
Ad aptive Highbeam Assist is only an aid.You are
re sponsible for adju sting theve hicle's lighting to
th e pr evailing light, visibility and traf fic condi‐
tions.

Fu nctions of ABS (Anti-lock Brake Sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, youwill 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
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐

WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an eme rgency braking situation is
increased.
#Depress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.

If yo udepr essthe brake pedal quickl y,BA S is
acti vated:
RBA S au tomatical lyboosts the brake pres‐
sure.
RBA S can short enthe braking dis tance.
RABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated.
Functions of ESP®(Electronic Stability Pro‐
gr am)
&
WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry
out vehicle stabilization. In addition, other
driving saf etysy stems are switched off.
#Drive on carefull y.
#Have ESP®checked at a qualified spe‐
cialist workshop.
&
WARNING Risk of skidding if ESP®is
deactivated
If yo u deactivate ESP
®, ESP®cannot car ry
out vehicle stabilization.
#ESP®should only be deactivated in the
fo llowing situations.
Mercedes‑AMG vehicles: observeth e no tes in
th e Supplement. Otherwise, you may failto rec‐
ognize dangers.
ESP
®can monito r and improvedriving stability
and traction in thefo llowing situations, within
ph ysical limits:
RWhen pulling away on wet or slippe ryroads.
RWhen braking.
RIn stro ng side winds when you are driving
fast erthan 50 mph (80 km/h). If
th eve hicle deviates from the direction desired
by the driver, ESP
®can stabilize theve hicle by
inter vening in thefo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP
®is deactivated if theå ESP®OFFwarn‐
ing lamp lights up continuously in the instrument
clus ter:
RDriving stability will no longe r be improved.
RCrosswind Assist is no longer active.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.
% When ESP
®is deactivated, you are still assis‐
te dby ESP®when braking.
ESP
®is inter vening if the÷ ESP®warning
lamp flashes in the instrument clus ter:
RDo not deacti vate ESP®.
ROnly depress the accelera tor pedal as far as
is necessar y.

Driving and pa rking

RAdapt your drivin gst yle to suit the cur rent
ro ad and weather conditions.
It can make sense todeactivate ESP
®inthefo l‐
lowing situations toimpr ovetraction:
RWhen using snow chains.
RIn deep snow .
ROn sand or gr avel.
% Spinning the wheels results in a cutting
action which pr ovides better grip.
If th e÷ ESP

ousl y,ESP®is not available due toa malfunction. Observ

ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP
®and
makes it possible topull away or accelerate on a
slippery sur face.
ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
RThe drive wheels are braked individually if
they spin.
RMore 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 (
