ESP
®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
4ETS (Electronic Traction System) 4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Only operate the vehicle for a maximum of
ten seconds on a brake dynamometer. Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! A function or performance test should only
be carried out on a twin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
When ESP ®
is deactivated, the åESP®
OFF
warning lamp lights up continuously. If the
÷ warning lamp and the åwarning
lamp are lit continuously, ESP ®
is not available
due to a malfunction.
Observe the information on warning lamps
(Y page 291) and display messages which may
be shown in the instrument cluster
(Y page 254).
i Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly.
Characteristics of ESP ® General notes
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the acceler-
ator pedal as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its previ-
ously selected status. Example:if ESP®
was
deactivated before the engine was switched off,
ESP ®
remains deactivated when the engine is
switched on again.

WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
It may be best to deactivate ESP ®
in the follow-
ing situations:
R when using snow chains
R in deep snow
R on sand or gravel
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle

R Engine torque is no longer limited and the
drive wheels are able to spin
The spinning of the wheels results in a cutting
action for better traction on loose surfaces.
R Traction control is still activated
R COLLISION PREVENTION ASSIST is no longer
available; nor is it activated if you brake firmly
with assistance from ESP ®
R PRE-SAFE ®
is no longer available; it is also not
activated if you brake firmly with assistance

ESP ®
trailer stabilisation General notes
ESP ®
trailer stabilisation is not available in
Mercedes-AMG vehicles.
If your vehicle/trailer combination begins to
lurch, ESP ®
assists you in this situation. ESP ®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com-
bination has stabilised.
Important safety notes G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident. Driving safety systems

Important safety notes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account road, weather or traffic
conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time, and for staying in lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g. in
heavy traffic or on winding roads)
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.

179Driving and parking Z

On steep uphill or downhill inclines or if there is
a malfunction, the transmission may also be
automatically shifted into position P.4MATIC
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
and 4ETS, it
improves the traction of your vehicle whenever
a drive wheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor over-
ride the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
! A function or performance test should only
be carried out on a twin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tyres (M+S tyres), with snow
chains if necessary. DSR (Downhill Speed Regulation)
General notes DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak-
ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or non-existent.
DSR controls the vehicle’s speed when it is acti- vated and the transmission is in position D,Ror
N. By accelerating or braking, you can always drive at a higher or a lower speed than that set
on the on-board computer.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account ofroad, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tyre conditions. Select a set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.

Observe here the "MOExtended tyres (tyres
with run-flat characteristics)" section
(Y
page 333).
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They only reach their full per-
formance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 367). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi- cle even if there is a total loss of pressure in one
or more tyres.
MOExtended tyres may only be used in conjunc- tion with an activated tyre pressure loss warning
system or with an activated tyre pressure mon- itor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (Y page 333).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you fit
tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 356). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the maximum
design speed of the vehicle, affix a correspond- ing warning label in the driver's field of vision.
This can be obtained at a qualified specialist
workshop. 350
