Driving safety systems61
Safety
Z

ETS traction control is part of ESP®. On vehicles
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 transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
Important safety notes
GWARNING
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.
If the 00BB ESP
®OFF warning lamp lights up
continuously, then ESP®is deactivated.
If the 00E5 ESP®warning lamp lights up contin-
uously, ESP®is not available due to a malfunc-
tion.
Observe the information on warning lamps
(
Ypage 234) and display messages which may
be shown in the instrument cluster
(
Ypage 204).
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Characteristics of ESP®
General information
If the 00E5 ESP warning lamp goes out before
beginning the journey, ESP®is automatically
active.
If ESP
®intervenes, the 00E5ESP®warning lamp
flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving. The engine starts automatically when
the driver wants to pull away again. ESP
®
remains in its previously selected status, e.g. if
ESP®was deactivated before the engine was
automatically switched off.
Deactivating/activating ESP®
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
You can select between the following states of
ESP
®:
RESP®is activated.
RESP®is deactivated.
GWARNING
If you deactivate ESP
®, ESP®no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP
®in the situations descri-
bed in the following.
It may be best to deactivate ESP
®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
Spinning the wheels results in a cutting action
which provides better grip.
iActivate 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 (Ypage 197).
ESP®deactivated:
The 00BB ESP®OFF warning lamp in the instru-
ment cluster lights up.

If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use the cruise con-
trol or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
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 freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
For more information on driving with snow
chains, see (
Ypage 305).
For more information on driving with summer
tires, see (
Ypage 305).
Observe the notes in the "Winter operation" sec-
tion (
Ypage 305).
Driving systems
Mercedes-Benz Intelligent Drive
Mercedes-Benz Intelligent Drive stands for inno-
vative driver assistance and safety systems
which enhance comfort and support the driver in
critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set a mile-
stone 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 vehi-
cle occupants and that of other road users. Further information on driving safety systems
(
Ypage 61).
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 important 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 overheating and wearing too
quickly.
You can use cruise control if you want to drive at
a steady speed for a prolonged period of time.
You can store any road speed above 20 mph
(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
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 maintaining a safe
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen 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 systems145
Driving and parking
Z

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be shif-
ted into position Pautomatically.
MAGIC BODY CONTROL
General notes
MAGIC BODY CONTROL consists of Active Body
Control (ABC), ROAD SURFACE SCAN, the
CURVE cornering function as well as automatic
vehicle stabilization in the event of a crosswind.
Your vehicle automatically adjusts its ride height
to reduce fuel consumption. The suspension
mode is adjusted according to your selection
(SPORT, COMFORT or CURVE), the road surface conditions and the vehicle load. A multifunction
camera detects bumps in the road surface
before the vehicle drives over them. This
reduces chassis movements.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
!The vehicle is lowered when the engine is
switched off. When parking, position your
vehicle so that it does not make contact with
the curb as the vehicle is lowered. Your vehi-
cle could otherwise be damaged.
Crosswind Assist
The crosswind stabilization operates by chang-
ing wheel loads through distortion of the ABC
spring struts. It reduces impairments in handling
when driving in a straight line and assists during
countersteering. Crosswind Assist is active in the speed range
between 50 mph (80 km/h)
and
130 mph (210 km/h) when driving straight
ahead or cornering gently.
Active Body Control ABC
Vehicle level
Mercedes-AMG vehicles: depending on the
vehicle level that has been selected, the vehicle
automatically adjusts its height dependent on
the current speed. The vehicle is lowered by up
to 0.4 in (10 mm) below the normal level as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
All other models: depending on the vehicle
level that has been set, the vehicle automatically
adjusts its height dependent on the current
speed. The vehicle is lowered by up to 0.6 in
(15 mm) as the speed increases. As the speed is
reduced, the vehicle is raised up to the set vehi-
cle height.
In the event of poor road surface conditions, the
vehicle automatically raises by up to 0.4 in
(10 mm) and harder damping is selected.
Select the "Normal" setting for normal road con- ditions and "Raised" for driving with snow chains
or in particularly poor road conditions.
The "Raised level" setting is canceled if you:
Rare driving faster than approximately 75 mph
(12 0km/ h).
Rdrive for approximately three minutes at a
speed above 50 mph (80 km/ h)
While driving, the raised level can only be selec-
ted at speeds of under 75 mph (120 km/h).

ROAD SURFACE SCAN
iThis function isnot availab le inall countries.
If you have selected the CURVE driving mode,
the ROAD SURFA CE SCA N function isavaila-
ble up to speeds of 60 km/h.
The ROADSURFA CE SCA N function monitors
the road infront of the veh icleusing multifunc-
tion camera 0043at the top of the windshield. This
function isautomatically active ifyou select
comfort suspension tuning. The system is
operational at speeds of up to 81 mph
(130 km/h).
This function allowsbumps inthe road surface
to be detected before the veh icle drives over
them. The spring struts are then actuate d, with
the result that chassis movements are signifi-
cantly reduced when driving over bumps.
The system isdeactivated when you select the
raised veh icleleve l,sports mode or the dynam ic
cornering function.
The system may be impaired or may not function
if:
Rthe road surface isinsuff iciently lit
Rthere ispoor vis ibility, e.g. snow, rain, fog or
spray
Rthere isglare, e.g. from the sun or from

AIRMATIC
General notes
AIRMATIC isan air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automatically to improve driving safety
and to reduce fuel consumption. There is also
the option to manually adjust the vehicle leve l.
AIRMATIC consists of level setting, level control
and the Adaptive Damping System ADS PLU S.

Comfort tuning
In comfort mode, 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.
XIf indicator lamp0044is not lit:press but-
ton 0043.
Indicator lamp 0044lights up. Comfort tuning is
selected.
Mercedes-AMG vehicles: theAMG Suspen‐
sion System COMFORTmessage appears in
the multifunction display.
All other models: theAIRMATIC COMFORT
message appears on the multifunction dis-
play.
If the driving speed is higher than 75 mph
(12 0km/ h), the vehicle is automatically low-
ered by another 0.4 in (10 mm) compared to the
normal level in comfort mode.
All vehicles except Mercedes-AMG vehicles:
if the driving speed is higher than 100 mph
(160 km/h) and "Comfort" mode is activated,
the vehicle is automatically lowered by 0.4 in
(20 mm).
Load compensation
The vehicle can compensate differences in the
vehicle level by raising or lowering the axles.
4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP®, it improves
the traction of your vehicle whenever 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 conditions.
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:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate 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 vehi-
cle with all wheels in full contact with the
ground.
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 sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
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.
