2014 MERCEDES-BENZ M-Class esp

It may be best to deactivate ESP
®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilize the
vehicle 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.
Deactivating/activating ESP ®X
To switch off: press button0002.
The 0017 ESP®
OFF warning lamp in the
instrument cluster lights up.
X To switch on: press button0002.
The 0017 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 000FESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning of the wheels results in a
cutting action for better traction on loose
surfaces.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
Off-road ESP ® An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Y page 248).
Off-road ESP ®
intervenes with a delayift here
is oversteering or understeering, thus
improving traction.
ESP ®
trailer stabilization G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from
swerving. 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
prevailing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction. Driving safety systems
73Safety Z

EBD (electronic brake force
distribution)
General information EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
Important safety notes
i
Observe the "Important safety notes"
sectio nfor driving safety systems
(Y page 66). G
WARNING
If EBD has malfunctioned, the rear wheels can
still 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
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 319) as well as
display messages (Y page 285).ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Y page 206) and hill start assist
(Y page 161). PRE-SAFE
®
Brake
General information i
Observe the "Important safety notes"
section (Y page 66).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
For PRE-SAFE ®
Brake to assist you when
driving, the radar sensor system must be
operational. With the help of the radar sensor system,
PRE-SAFE
®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead, and
reduce the effects of such a collision. If PRE-
SAFE ®
Brake has detected a risk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
Important safety notes G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergenc ybraking cannot prevent
a collision. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintai nthe appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself. 74
Driving safety systemsSafety

If you have activated DSR (Y
page 246), PRE-
SAFE ®
Brake is deactivated. STEER CONTROL
General information STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in
particular if:
R both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
R the vehicle starts to skid.
Important safety notes i
Observe the "Important safety notes"
section (Y page 66).
If ESP ®
is malfunctioning, you will not receive
steering support from STEER CONTROL.
Powers teering will, however, continue to
function. Theft deterrent locking system

General notes Bear in mind that the engine can be started
by any of the vehicle occupants if there is a
KEYLESS-GO key in the vehicle.
Locking/unlocking centrally 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
conventional SmartKey. Unlock the vehicle
by using KEYLESS-GO, for instance, and lock
it using the 000Bbutton on the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the key and the
corresponding door handle must not be
greater than 3 ft (1 m). KEYLESS-GO checks whether a valid
SmartKey is in the vehicle by periodically
establishing a radio connection between the
vehicle and the SmartKey. This happens:

touched
R when starting the engine
R while the vehicle is in motion X

Important safety notes
Your vehicle may be equipped with a sliding
sunroof or a panorama roof with power tilt/
sliding panel. In this section, the term "sliding
sunroof" refers to both types of sliding
sunroof. G
WARNING
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
procedures. If somebody becomes trapped:
R
release the switch immediately, or
R during automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be
stopped. G
WARNING
