ESP ®
(Electronic Stability Program)
General notes
i Observe the "Important safety notes" sec-
tion ( Y
page 65).
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tires 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 stabilize 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 stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
i Observe the "Important safety notes" sec-
tion ( Y
page 65).
ETS traction control is part of ESP ®
. On vehi-
cles with 4MATIC, 4ETS 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, even if you
deactivate ESP ®
.

tion ( Y

G WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop. Vehicles without 4MATIC: when towing
your vehicle with the front axle raised, it is
important that you observe the notes on ESP ®
( Y
page 323).

on sand or gravel R
on specially designated roads when the
vehicle's own oversteering and understeer-
ing characteristics are desired
Driving in SPORT handling mode or without
ESP ®
requires an extremely qualified and
experienced driver.

as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilize the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.

Import ant safety notes
G WARNIN G
If road and weather condition s are poor ,
trailer stabilization will no t be able to preven t
th e vehicle/traile r combination from swerv-
ing . Trailers wit h a high cente r of gravity can
tip ove r before ES P ®
can detect this. Ther e is
a ris k of an accident.
Always adapt your driving style to th e prevail-
ing road and weather conditions.
If your veh icle wit h trailer (vehicle/trailer
co mbin ation) begins to lurch, you can only
st abiliz e the vehicle /t railer combination by
depr essing the brake firmly.
ESP ®
trailer st abiliz ation is active above
spee ds of about 65 km/h.
ESP ®
trailer stabilization does not work if
ESP ®
is deactivated or disabled because of a
malfunction.
EBD (electronic brake force distribu-
tion)
General information
EBD mon it ors and controls the brake pres-
sure on the rear wheels to improve driving
st abilit y while braking. Important safety notes
i Observe the "Im portant safety notes" sec-
tion ( Y
page 65).
G WARNIN G
If EB D is malfunctioning, th e rear wheels can
lock, e.g. under full braking . This increases th e
ris k of skiddin g and an accident.
You should therefor e adapt your driving style
to th e different handlin g characteristics. Hav e
th e brak e system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps ( Y
page 261) as well as dis-
play messages ( Y
page 230).
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 187) and
hill start assist ( Y
page 151).
STEER CONTROL
General information
ST EER CONTROL helps you by transmitting a
noticea ble steering force to the steering
wheel in the direction required for vehicle
st abiliz ation.
This steering assistance is pro vide d in partic-
ular if: R
both right wheels or both left wheels are on
a wet or slippery road surface when you
brake. R
the veh icle starts to skid.

Centrally locking and unlocking the
vehicle from the insideYou can centrally lock or unlock the vehicle
from the inside. This can be useful if you wish
to lock the vehicle before pulling away, for
example.
X
To unlock: press button C .X
To lock: press button D .
If all the doors and the trunk lid are closed,
the vehicle locks.
Meanwhile, the fuel filler flap will not be
locked or unlocked.
You cannot unlock the vehicle centrally from
the inside if the vehicle has been locked with
the SmartKey or KEYLESS-GO.
You can open a door from inside the vehicle
even if it has been locked. You can open the
rear doors from inside the vehicle unless they
are secured by the child-proof lock
( Y
page 64).
If the vehicle has previously been locked with
the SmartKey from the outside, opening a
door from the inside will trigger the anti-theft
alarm system. Switch off the alarm
( Y
page 73). If a locked door is opened from the inside, the
previous unlock status of the vehicle will be
taken into consideration if: R
the vehicle was locked using the locking
button for the central locking, or R
if the vehicle was locked automatically
The vehicle will be fully unlocked if it had pre-
viously been fully unlocked. If only the driver's
door had been previously unlocked, only the
door which has been opened from the inside
is unlocked.
