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 vehicle 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) i
Observe the "Important safety notes" sec-
tion (Y page 78).
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 trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.
Off-road 4ETS (Electronic Traction Sys-
tem) A 4ETS system specifically suited to off-road
terrain is activated automatically once the off- road program is activated (Y page 250).
Off-road ESP ® An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Y page 250).
The off-road ESP ®
intervenes with a delay if
there is oversteering or understeering, thus
improving traction.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 78). 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.
If the å ESP®
OFF warning lamp lights up
continuously, ESP ®
is deactivated.
If the ÷ ESP®
warning lamp lights up con-
tinuously, ESP ®
is not available due to a mal-
function.
Observe the information on warning lamps
(Y page 381) and display messages which
may be shown in the instrument cluster
(Y page 336).
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 accel-
erator pedal as far as is necessary.
X Adapt your driving style to suit the prevail-
ing 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 pre-
viously selected status. Example:if ESP®
was deactivated before the engine was
switched off, ESP ®
remains deactivated when
the engine is switched on again. Driving safety systems

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 fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
R when driving off-road (vehicles without off-
road program)
Activate ESP ®

engine is switched on. If the display is
approaching limit ;and you remove your
foot from the accelerator pedal, the display
empties again. The combustion engine is
not switched on. At low speeds, you can
thereby control the electric operation
usage so that you only drive in electric
mode.
Driving with the combustion engine: the
electric motor supports the combustion
engine by providing additional torque
(boost mode) until the display reaches

Driving using the internal combustion
engine and energy recuperation The internal combustion engine powers the
vehicle. The electric motor is being operated
as an alternator, e.g. in overrun mode and
when braking (Y page 299). The kinetic
energy of the vehicle is converted into elec-
trical energy. The high-voltage battery is
charging.

engine by providing additional torque when
the accelerator is depressed rapidly.
Overrun mode or braking
There are three possible operating modes
when the hybrid vehicle is decelerating:
R When coasting and decelerating, energy
recuperation is already taking place
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R When braking gently, the electric motor
increases the deceleration of the vehicle.
Energy recuperation is increased
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R During heavy braking, the service brake is
also used to slow down the vehicle. Both
systems work together.
Driving in the city
Energy is recuperated during frequent decel-
eration and stopping in city traffic.
The vehicle can be driven by the electric
motor alone up to a speed of approximately
140 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 298).
Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads:
R rapid acceleration (boost mode)
R constant energy consumption
R energy recuperation
R electric operation mode
Depending on the characteristics of the
route, there may be a lot of recuperated
energy available. This reduces consumption
and emissions. Driving on the motorway
When driving on a motorway, the decrease in
wasted power has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his foot from the accel-
erator pedal in drive program Eand a speed of
160 km/h is not exceeded, the combustion
engine is automatically switched off.
Further information on the automatic engine
switch-off (Y page 298).
ECO start/stop function General notes
The ECO start/stop function switches the
internal combustion engine off automatically
when the vehicle stops moving and at high
speeds (Y page 299).
All vehicle systems remain active, e.g. the
automatic climate control.
The ECO start/stop function is only available in drive programs Cand E. Electric-only oper-
ation is only possible in drive programs Cand
E. Additional information for drive programs
(Y page 295).
Automatic engine switch-off
The internal combustion engine is switched
off automatically if:
R the driver removes his foot from the accel-
erator in drive program Eand a speed of
160 km/h is not exceeded (Y page 299)
R the internal combustion engine has
reached its operating temperature
R the driver's seat belt is fastened and the
driver's door is closed
R the driver only slightly depresses the accel-
erator pedal in order to, for example, main- tain the current speed for a limited distance
R the bonnet is closed and engaged properly
R the high-voltage battery is charged suffi-
ciently
R no malfunctions are present in the hybrid

General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres) Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow- ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended tyre pressures for various
operating conditions can be found in the tyre pressure table on the fuel filler flap. Further
