WARNING
If ESP ®
is mal functioning, ESP ®
is unable to
stabilis ethe vehicle. In addition, othe rdriving
safety systems are switche doff. This increa-
se st he risk of skiddi ngand an accident.
Driv eonc arefully. Have ESP ®
checked at a
qualified specialis tworkshop.
! Only operat ethe vehicle for amaximum
of ten seconds on abrake dynamometer.
Switch off th eignition.
Application of the brakes by ESP ®
ma yoth-
erwise destroy the brake system.
! Afunction or performanc etest should
only be carried out on atwin-axle dyna-
mometer .Before you operate th evehicle
on such adynamometer, pleas econsult a
qualified workshop. You coul dotherwise
damage the drive train or the brake system.
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ousl ywhen the engin eisrunning.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to amalfunction.
Observe the information on warning lamps
(Y page 329 )and display message swhich
ma ybes hown in the inst rument cluster
(Y page 291).
If ESP ®
detects that th evehicle is deviating
from the direction desired by the driver, one
or mor ewheels ar ebrake dtos tabilise the
vehicle .The engin eoutput 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.
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 condi tions.
i Only use wheels with the recommended
tyr es izes. Only then will ESP ®
func tion
properly.
4ETS (Electronic Traction System) Traction con
trol is par tofESP®
.
Tractio ncontrol brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slipper ysurfaces, for
example if the road surface is slippery on one
side .Ina ddition, mor edrive torqu eistrans-
ferre dtot he wheel or wheels with traction.
Traction con trol remains active if you deacti-
vate ESP ®

Deactivating/activating ESP
®G
WARNING
If you deactivat eESP®
,E SP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivat eESP®
in th esituation sdescri-
bed in th efollowing. X
To switch off: press button:.
The å ESP®
OF Fw arnin glamp in the
instrumen tcluster lights up.
X To switch on: press button:.
The å ESP®
OFF warnin glamp in the
instrumen tcluster goes out.
ESP ®
is activated automatically when the
engin eisstarted.
The ECO start/stop fun ction switches the
engin eoff automaticall yifthe vehi cles tops

start sautomatically. ESP ®
remain sinits pre-
viousl yselected status. Example: if ESP ®
was
deactiva tedb efor ethe engine was switched
off ,ESP ®
remains deactivated when the
engine is switched on again.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
th ei nstrumen tcluster flashes. In such situa-
tions, ESP ®
will not stabilise th evehicle. It may be best to deact
ivateESP®
in the fol-
lowing situations:
R when using sno wchains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longe rimproves driving stab ility.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R engine torque is not limited and the drive
wheels are abl etospin. The spinnin gofthe

trailer stabilisation G
WARNING
If roa dand weather conditions are poor,
trailer stabilis ation will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with ahigh centre of gravit ycan
tip over before ESP ®
can detect this. There is
ar isk of an accident.
Always adap tyour driving style to the prevail-
ing road and weather conditions.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/
trailer combination by depressin gthe brake
firmly. Driving safety systems
67Safety Z

In this situation, ESP
®
assist syou and can
detec tifthe vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by brakin gand limiting the engine outp ut until
the vehicle/trailer combinatio nhas stabi-
lised.
Trailer stabilisation is active above speeds of
about 60 km/h.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of amal-
function.
Crosswin dAssist Strong crosswinds can cause your vehicle to
deviate from astraight course. The crosswind
driving assistance function integrated into
ESP ®
significantly reduces thes eeffects.
ESP ®
intervene sautomatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
When driving on straight roads or gentle
bends ,your vehicle is kept safel yonc ourse
by astabilising brake intervention.
Crosswind driving assistance is active above
av ehicle speed of 80 km /h.
Crosswind driving assistance does not work
if ESP ®
is deactivated or disabled because of
am alfunction. EBD (electronic brake force distribu-
tion)
i Observe the "Importan tsafety notes" sec-
tion (Y page 61). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses the risk of skidding and an accident.
You should therefor eadapt your driving style
to the different handling characteristics. Have
the brak esystem checked at aqualified spe-
cialist workshop. Observe information regarding indicator and
warning lamps (Y
page 327) as well as dis-
play messages (Y page 293).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 211) and
hill start assist (Y page 162). PRE-SAFE

Brake
i Observe the "Important safety notes" sec-
tion (Y page 61).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimise
the risk of acollision with avehicle in front or

SAFE ®
Brake has detected arisk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE ®
Brake cannot prevent acollision withou tyour

This func tion will issue awarning if:
R at speeds of around 30 km/ horm ore over
several seconds, the distance maintained
to the vehicle travellin ginfront is insuffi-
cient.
The · distance warning lamp then lights
up in th einstrument cluster.
R at as peed of approximately 7km/h or
