instrument cluster lights up.
XTo activate: press button :.
The å ESP®OFF warning lamp in the
instrument cluster goes out.
Characteristics when ESP®is deactivated
If ESP®is deactivated and one or more wheels
start to spin, the ÷ESP®warning lamp in the
instrument cluster flashes. In such situations,
ESP
®will not stabilize the vehicle.
If you deactivate ESP®:
RESP®no longer improves driving stability.
REngine torque is no longer limited and the
drive wheels are able to spin.
RTraction control is still activated.
RESP®still provides support when you brake
firmly.
RMercedes-AMG vehicles: and are driving a
speed at above 62 mph (100 km/h), ESP®still
intervenes when one wheel reaches its grip
limit even though it is deactivated.
RAll other models: and are driving at a speed
above 37 mph (60 km/h), ESP®still inter-
venes when one wheel reaches its grip limit
even though it is deactivated.
Mercedes-AMG vehicles: if ESP
®is deactiva-
ted, it is reactivated automatically if you are
driving at a speed above 62 mph (100 km/h) or
you exceed a certain lateral acceleration.
All other models: if ESP
®is deactivated, it is
re
activated automatically if you are driving at a
speed above 37 mph (60 km/h) or you exceed a
certain lateral acceleration.
Trailer stabilization
General information
If your vehicle/trailer combination begins to
swerve, 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 stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle with trailer (vehicle/trailer com-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.
ESP
®trailer stabilization is active above speeds
of approximately 37 mph (60 km/h).
ESP
®trailer stabilization does not work if ESP®
is deactivated or malfunctioning.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 58).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 194) as well as display
messages (Ypage 176).
ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
(
Ypage 142) and hill start assist (Ypage 107).

SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart 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.
GWARNING
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 mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart- Key. A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving

Ypage 170).
You will receive visual and acoustic locking con-
firmation if all components were able to be
locked.
When the surround lighting is activated via the
on-board computer, it lights up when it is dark
after the vehicle is unlocked with the SmartKey (

environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
The SmartKey batteries contain perchlorate
material, which may require special handling
and regard for the environment. National guide-
lines must be observed during disposal. In Cal-
ifornia, see www.dtsc.ca.gov/

Sliding sunroof
Important safety notes
GWARNING
While opening and closing the sliding sunroof, body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity during the opening and closing pro-
cedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop- ped.
GWARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be
damaged.
!The weather can change abruptly. It could
start to rain or snow. Make sure that the slid- ing sunroof is closed when you leave the vehi-
cle. The vehicle electronics can be damaged if
water enters the vehicle interior.
Resonance noises can occur in addition to the
usual airflow noises when the sliding sunroof is
open. They are caused by minor pressure fluc-
tuations in the vehicle interior. Change the posi-
tion of the sliding sunroof or open a side window
slightly to reduce or eliminate these noises.

Steering wheel EASY-ENTRY/EXIT fea-
ture
Important safety notes
GWARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel and the driver's seat, you
and other vehicle occupants – particularly
children – could become trapped. There is a
risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the seat and
the steering wheel.
If somebody becomes trapped:
Rpress one of the memory function position
buttons, or
Rpress one of the memory function memory
buttons, or
Rmove the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving
The adjustment process is stopped.
GWARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off.
!Do not activate the EASY-ENTRY/EXIT fea-
ture, if the seat backrest is reclined too far
backwards. This can damage the front or rear
seats. You must first move the backrest to a
vertical position.
The EASY-ENTRY/EXIT feature makes getting in
and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board computer
(
Ypage 170).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active
The steering wheel moves upwards and towards
the dashboard if:
Ryou remove the SmartKey from the ignition
lock or
Ryou open the driver's door and the SmartKey
is in position 0or 1in the ignition lock
iThe steering wheel only moves upwards and
towards the dashboard if it has not already
reached the upper steering limiter.
Position of the steering wheel for driv-
ing
The steering wheel is moved to the last selected position when:
Rthe driver's door is closed
Ryou insert the SmartKey into the ignition lock
The last position of the steering column is stored
when you switch off the ignition or when you
store the setting with the memory function
