Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 66)
R BAS (Brake AssistSystem) (Y page 67)
R BAS PLUS with Cross-Traffic Assist ( Brake

R ADAPTIVE BRAKE (Y page 74)
R PRE-SAFE ®
Brake (Y page 74)
R STEER CONTROL (Y page 76)Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt
your driving style to suit the prevailing road,
weather and traffic conditions and maintain a safe distance from the vehicle in front. Drive
carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tires and the
road surface. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. (Y page 358).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains. Only in this way will the driving safety systems described in this section work as
effectively as possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
The 0025 ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 286) and
display messages which may be shown in the
instrument cluster (Y page 251).66
Driving safety systemsSafety

Only deactivate ESP
®
in the situations descri-
bed in the following.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
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 ®
You can deactivate or activate ESP ®
via the
on-board computer.
X To deactivate: (Ypage 72).
The 00BB ESP®
OFF warning lamp in the
instrument cluster lights up.
X To activate: (Ypage 72).
The 00BB 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 00E5ESP®
warning lamp in
the instrument cluster does not flash. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the driven wheels can spin.
The spinning of the wheels results in a cut-
ting action for better traction on loose sur-faces.
R traction control is still activated.
R PRE-SAFE ®
is no longer available, nor is it
activated if you brake firmly and ESP ®
intervenes. R
PRE-SAFE ®
Brake is no longer available, it
is also not activated if you brake firmly and
ESP ®
intervenes.
R ESP ®
still provides support when you brake
firmly.
Crosswind Assist General information
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP ®
significantly reduces these effects.
ESP ®
intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
ESP intervenes with stabilizing braking to
assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 50 mph (80 km/h) when driving
straight ahead or cornering gently.
Important safety notes
Crosswind Assist does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake force distribu-
tion)
General information EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
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 Driving safety systems

Z

The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. The vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
For more information on driving with snow
chains, see (Y page 361).
For more information on driving with summer tires, see (Y page 360).
Observe the notes in the "Winter operation"
section (Y page 360). Driving systems
Mercedes-Benz Intelligent Drive
Mercedes-Benz Intelligent Drive stands for
innovative driver assistance and safety sys-
tems which enhance comfort and support the
driver in critical situations. With these intelli-
gent co-ordinated systems Mercedes-Benz
has set a milestone on the path towards
autonomous driving.
Mercedes-Benz Intelligent Drive embraces all elements of active and passive safety in one
well thought out system – for the safety of the
vehicle occupants and that of other road
users.
Further information on driving safety systems (Y page 66). Cruise control
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into
a lower gear in good time on long and steep
downhill gradients. This is especially impor-
tant if the vehicle is laden. By doing so, you
will make use of the braking effect of the
engine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con- ditions make it appropriate to maintain a
steady speed for a prolonged period. You canstore any road speed above 20 mph
(30 km/h).
Important safety notes If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
your lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new driver of the speed stored. Driving systems
183Driving and parking Z

i
If one of the doors is open, the vehicle is
not lowered.
Vehicle level Setting the raised vehicle level
It is possible to choose between the "Normal"
and "Raised" vehicle levels below a speed
50 mph (80 km/h). Select the "Normal" set-
ting for normal road surfaces and "Raised" for
driving with snow chains or on particularly
poor road surfaces. Your selection remains
stored even if you remove the SmartKey from
the ignition lock.
X Start the engine.
If indicator lamp 0044is not lit:
X Press button 0043.
Indicator lamp 0044lights up. The vehicle is
raised by 0.6 in (15 mm) compared to the
normal level.
The Vehicle Rising
Vehicle Rising message appears in
the multifunction display.
i The message disappears after ten sec-
onds, irrespective of the level reached. If
necessary, the vehicle is raised further.
The "Raised level" setting is canceled if you:
R drive faster than 75 mph (120 km/h).
R drive for approximately three minutes at a
speed over 50 mph (80 km/h).
The "Raised level" remains active when you
are not driving within these speed ranges. Setting the normal vehicle level
X Start the engine.
If indicator lamp 0044is lit:
X Press button 0043.
Indicator lamp 0044goes out. The vehicle is
adjusted to the height of the currently
selected drive program (Y page 167).
Suspension tuning General notes
The Adaptive Damping System automatically
controls the calibration of the dampers.
The damping is tuned individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sports or com-
fort
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
Sports tuning
In the "Sport" and "Sport Plus" drive pro-
grams, the firmer suspension setting ensures
even better contact with the road. Select this mode when employing a sporty driving style,
e.g. on winding country roads.
X Select the Sor S+ drive program with the
AGILITY SELECT switch (Y page 167).
The vehicle is lowered by 0.6 in (15 mm)
compared to the normal level.
Comfort tuning
In the "Eco" and "Comfort" drive programs,
the driving characteristics of your vehicle are
more comfortable. Therefore, select this
mode if you favor a more comfortable driving
style. Select comfort mode also when driving
fast on straight roads, e.g. on straight
stretches of highway.
X Select the Eor Cdrive program with the
AGILITY SELECT switch (Y page 167).
The vehicle is raised to the normal level. 198
Driving systemsDriving and parking

When driving at speeds above 80 mph
(125 km/h) , the vehicle is automatically low-
ered by 0.6 in (15 mm) in the Eand Cdrive
programs. When driving at speeds below
50 mph (80 km/h) the vehicle is raised again. 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con- ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far as
necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park- ing space. When maneuvering, parking or
pulling out of a parking space, make sure that
there are no persons, animals or objects in
the area in which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R shift the transmission to position D,Ror N
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors General notes
PARKTRONIC does not take objects into con-
sideration that are:
R below the detection range, e.g. people, ani-
mals or objects.
R above the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps. Driving systems
