WARNING Risk of injury from adjusting
th eve hicle settings while theve hicle is in
motion
Yo u could lose cont rol of theve hicle in the
fo llowing situations:
Rifyo u adjust the driver's seat, the head
re stra int, thesteering wheel or the mir ror
while theve hicle is in motion
Rifyo ufa sten your seat belt while theve hi‐
cle is in motion
#Before starting the engine: adjust the
driver's seat, the head restra int, the
st eering wheel or the mir ror and fasten
yo ur seat belt.
&
WARNING Risk of accident due tomis‐
judgment of dis tances when using the
passenger mir ror
The outside mir ror on the front passenger
side reflects objects on a smaller scale. The
objects in view are in fact closer than they
appear.
As a result, you may mis judgethe dis tance
between you and thero ad user driving
behind you, forex ample, when changing
lanes.
#Therefore, alw ays look over your shoul‐
der in order toensure that you are
aw are of the actual dis tance between
yo u and thero ad users driving behind
yo u.

WARNING Risk of burn s and poisoning
due tothe anti- glare mir ror electrolyte
Electrolyte may escape if theglass in an
automatic anti-glare mir ror breaks.
The electrolyte is harmful and causes ir rita ‐
tion. It must not come into contact wi thyour
skin, eyes,respiratory organs or clo thing or
be swallo wed.
#Ifyo u come into contact with electro‐
ly te , obser vethefo llowing:
RRinse the electrolyte from your skin
and seek medical attention immedi‐
atel y.
RIf electrolyte comes into contact
with your eyes, rinse them thor‐
oughly with clean water and seek
medical attention immediately.
RIf th e electrolyte is swallo wed,
immediately rinse your mouth out
th oroughly. Do not induce vomiting.
Seek medical attention immediately.
RImmediate lych ange out of clo thing

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

If BA S is malfunctioning, the braking dis tance
in an eme rgency braking situation is
increased.

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.

WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry

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

#ESP®should only be deactivated in the
fo llowing situations.
Mercedes‑AMG vehicles: observeth e no tes in

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

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.

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

RImpr oved driving stability when braking,
especially on bends.

Fu nction of Active Brake Assi st
Active Brake Assi stconsist s of:
RDistance warning function
RAu tonomous braking function
RSituation-dependent braking assist ance
RVehicles with Driving Assistance Pack‐
age: Evasi veSteering Assist
Ac tive Brake Assi stcan help youto minimize the
ri sk of a collision with vehicles or pedestrians or
to reduce the ef fects of such a collision. If
Ac tive Brake Assi sthas de tected a risk of colli‐
sion, youwill bewarned visually and acousti‐
cally.
If yo udo not react tothe visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal situations.
In especially critical situations, Active Brake
Assi stcan initiate autonomous braking direct ly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion.
If yo uappl yth e brake yourself in a critical situa‐
tion or applyth e brake during autonomous brak‐
ing, situation-dependent braking assis tance
occurs . This increases the brake pressure up to
maximum full-s top braking if necessar y.
If th e autonomous braking function or the situa‐
tion-dependent braking assis tance is trig gered,
additional pr eventive measure sfo r occupant
pr otection (PRE-SAFE®) may also be initiated, if
th eve hicle is equipped with these.

In such cases,Active Brake Assi stmight:
RGive a warning or brake without reason
RNo t give a warning or not brake
#Alw ays pay careful attention tothe traf‐

WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐

In addition, thesteering support of Evasive
St eering Assist is generally not suff icientto

In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide

Rnot give awa rning or not pr ovide assis‐
ta nce
#Alw ays pay careful attention tothe traf‐

St eering Assist alone.
#Be ready tobrake and take evasive
action if necessar y.
#Preve ntthe assis tance byactively steer‐
ing in non-critical driving situations.
#Drive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐
cle.
Also obser vethe sy stem limitations of Evasive
