Operator's Manual
This Supplement provides information on all the
important functions of your AMG vehicle that are
either not described or differ from the descrip‐
tions in thevehicle Operator's Manual. This
information supplements or replaces the corre‐
sponding sections in thevehicle Operator's Man‐
ual. Under no circumstances does the Supple‐
ment replace the Operator's Manual.
This Supplement describes all models, and
standard and optional equipment foryour vehi‐
cle, as available at the time of going to press.
Country-specific differences are possible. Bear
in mind that your vehicle may not feature all
functions described here. This is also the case
for systems and functions relevant to safety.
Therefore, the equipment on your vehicle may
differ from that in the descriptions and illustra‐
tions.
The original purchase contract documentation
foryour vehicle contains a list of all of the sys‐
tems in your vehicle.
Should you have any questions concerning

maintenance work or any required repairs
carried out, this could result in malfunctions
or system failures.
#Always have the prescribed service/
maintenance work as well any required
repairs carried out at a qualified spe‐
cialist workshop.
&WARNING Risk of accident and injury as
aresult of incorrect modifications to
electronic component parts
Modification to electronic components, their
software or wiring could impair their function
and/or the function of other networked com‐
ponent parts. In particular, systems relevant
to safety could also be affected.
As a result, they may no longer function as
intended and/or endanger the operating
safety of thevehicle.
#Nevertamper with the wiring and elec‐
tronic component parts or their soft‐
ware.

Driving and driving safety systems
Functions of ESP®(Electronic Stability Pro‐
gram)
&WARNING Risk of skidding if ESP®is
malfunctioning
If ESP®is malfunctioning, ESP®cannot carry
out vehicle stabilization. In addition, other
driving safety systems are switched off.
#Drive on carefully.
#Have ESP®checked at a qualified spe‐
cialist workshop.
You can select between thefollowing modes of
ESP®:
RESP®ON
RESP®SPORT
RESP®OFF
Characteristics when ESP®is activated
ESP®monitors and improves driving stability and
traction, particularly in thefollowing situations:
RWhen pulling away on wet or slippery road‐
ways.
RWhen braking.
RIn strong side winds when you are driving
faster than 47 mph (75 km/h).
ESP®can stabilize thevehicle by intervening in
thefollowing ways:
ROne or more wheels are braked.
RThe engine output is adapted according to
the situation.
ESP®is activated every time the engine is star‐
tedregardless of whether ESP®was in ESP®
16 Driving and parking

SPORT or deactivated before the engine was
switched off.
If the÷ESP®warning lamp flashes in the
instrument cluster, one or severalvehicle wheels
has reached its grip limit:
RAdapt the driving styleto suit the prevailing
road and weather conditions.
RDo not deactivate ESP®under any circum‐
stances.
ROnly depress the accelerator pedal as far as
is necessary.
Characteristics when ESP®SPORT is activa‐
ted
&WARNING Risk of skidding if ESP®
SPORT is used incorrectly
When you activate ESP®SPORT, there is an
increased risk of skidding and having an acci‐
dent.
#Activate ESP®SPORT only in the cir‐
cumstances described below.
Select ESP®SPORT when thevehicle's own
oversteering and understeering characteristics
are desired, e.g. on designated roads.
Driving with ESP®SPORT or with ESP®deactiva‐
tedrequires an extremely qualified and experi‐
enced driver.
If ESP®SPORT is activated and one or more
wheels start to spin, the÷ESP®warning
lamp on the instrument clusterflashes. ESP®
then only stabilizes thevehicle to a limited
degree.
ESP®SPORT also has thefollowing characteris‐
tics:
RESP®only improves driving stability to a limi‐
ted degree.
RETS/4ETS traction control is still active.
RThe engine's torque is only restricted to a
limited degree and the drive wheels can spin.
The spinning of the wheels results in a cut‐
ting action for better traction on loose surfa‐
ces.
RESP®continues to provide assistance when
the brakes are firmly applied.
RCrosswind Assist is no longer active.
Characteristics when ESP®is deactivated
&WARNING Risk of skidding if ESP®is
deactivated
If you deactivate ESP®, ESP®cannot carry
out vehicle stabilization.
#ESP®should only be deactivated in the
following situations.
When ESP®is deactivated, theåESP®OFF
warning lamp and theESP OFF message light up
continuously in the instrument cluster.
Deactivating ESP®has thefollowing effects:
RDriving stability will no longer be improved.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.
RCrosswind Assist is no longer active.
Driving and parking 17

%Even when ESP®is deactivated, you are still
assistedby ESP®when braking hard.
It may be best to activate ESP®SPORT or deacti‐
vate ESP®in thefollowing situations:
RWhen using snow chains.
RIn deep snow.
ROn sand or gravel.
%Spinning the wheels results in a cutting
action, which enhances traction.
%Activate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize thevehicle
if thevehicle starts to skid or a wheel starts
to spin.
If the÷ESP®warning lamp lights up continu‐
ously even when ESP®is activated, ESP®is not
available due to a malfunction.
Observe any information which may be displayed
in the instrument cluster:
RWarning and indicator lamps
RDisplay messages
ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP®.
ETS/4ETS can improve thevehicle's traction by
intervening in thefollowing ways:
RThe drive wheels are braked individually if
they spin.
RMore drive torque is transferred to the wheel
or wheels with traction.
