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 ®
.

i Observe the "Important safety notes" sec-
tion ( Y
page 65).
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 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.
i Activate ESP ®
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.

trailer stabilizationGeneral info rm ation
If your veh icle/t railer combination begins to
swerve, ESP ®
assists you in this situation.
ESP ®
slows the vehicle down by braking and
limit ing the engine output unt il the vehicle/
trailer co mbin ation has stabilized.
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.

Important safety notes
G WARNING
If children are left unsupervised in the vehicle,
they could: R
open the doors, thus endangering other
people or road users. R
get out and disrupt traffic. R
operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they: R
release the parking brake. R
shifting the automatic transmission out of
park position PR
Start the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
G WARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a
risk of an accident. Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the SmartKey: R
with electronic devices, e.g. a mobile
phone or another SmartKey. R
with metallic objects, e.g. coins or metal
foil. R
inside metallic objects, e.g. a metal case.
Vehicles with KEYLESS-GO start function:
do not keep the SmartKey in the cargo com-
partment. Otherwise, the SmartKey may not
be detected, e.g. when starting the engine
using the Start/Stop button.

The turn signals flash once when unlocking
and three times when locking.
When the locator lighting is activated in Audio
20/COMAND, it lights up when it is dark after
the vehicle is unlocked with the remote con-
trol (see separate operating instructions).
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using
the on-board computer ( Y

KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a
SmartKey in the vehicle.
Locking and unlocking
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a con-
ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the 7 button on the SmartKey.
The driver's door and the door at which the
handle is used, must both be closed. The
SmartKey must be outside the vehicle. When
locking or unlocking with KEYLESS-GO, the
distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m). A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example: R
when starting the engine R
whilst driving R
when the external door handles are
touched R
during convenience closing
X
To unlock the vehicle: touch the inner
surface of the door handle. X
To lock the vehicle: touch sensor sur-
face C or D .
Make sure that you do not touch the inner
surface of the door handle. X
Convenience closing feature: touch
recessed sensor surface D for an exten-
ded period.
