Important safety notes If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather 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 ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section ( Y
page 343).
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 vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently. 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 261) and dis-
play messages which may be shown in the
instrument cluster ( Y
page 228).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving.
BAS (Brake Assist System)
General information BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.

It may be best to deactivate ESP ®
in the follow-
ing situations: R
when using snow chains R
in deep snow R
on sand or gravel
Spinning the wheels results in a cutting action
which provides better grip.
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.

G DANGER
If th e exhaust pipe is blocke d or adequate
ventilation is no t possible, poisonous gase s
suc h as carbon monoxide (CO) may ente r th e
vehicle. This is th e case, e.g. if th e vehicl e
become s trapped in snow. There is a ris k of
fatal injury.
If you leav e th e engin e or th e auxiliary heating
running, mak e sur e th e exhaust pipe and area
around th e vehicl e are clear of snow. To
ensur e an adequate supply of fresh air, open a
window on th e side of th e vehicl e that is no t
facing int o th e wind.
Hav e your vehicl e winter-proofe d at a qualified
specialist workshop at th e onset of winter.
Drive particularly carefully on slipper y roa d sur -
faces. Avoid sudden acceleration , steering and
braking maneuvers . Do no t use th e cruise con-
trol or DISTRONI C PLUS.
If th e vehicl e threaten s to skid or canno t be
stoppe d when moving at low speed:X
Shift th e transmission to position N .
The outside temperature indicator is no t
designed to serve as an ice-warning device and
is therefor e unsuitable for that purpose .
Changes in th e outside temperature are dis-
played after a short delay.
Indicate d temperatures jus t abov e th e freezing
poin t do no t guarantee that th e roa d surfac e is
free of ice . The roa d may s till be icy, especially in
w ooded area s or on bridges .
You should pay special attention to roa d condi-
tion s when temperatures are around freezing
point.

Cruise cont rol
Gene ra l notesCruis e control maintains a constan t roa d speed
for you. It brakes automatically in order to avoid
exceedin g th e set speed. Change int o a lower
gear in goo d time on lon g and steep downhill
gradients . This is especially important if th e
vehicl e is laden . By doin g so, you will mak e use
of th e braking effec t of th e engine. This relieves
th e load on th e brak e system and prevents th e
brakes from overheating and wearing to o
quickly.
You can use cruise control if you wan t to drive at
a steady speed for a prolonged period of time.
You can store any roa d speed abov e 20 mph
(30 km/h).
Import ant safety notesIf you fail to adapt your drivin g style, cruise con-
trol can neither reduce th e ris k of an acciden t
no r override th e laws of physics . Cruis e control
canno t tak e int o accoun t th e road, traffic and
weather conditions. Cruis e control is only an
aid. You are responsibl e for maintainin g a saf e
distanc e to th e vehicl e in front, for vehicl e
speed, for braking in goo d time and for stayin g in
lane.
Do no t use cruise control :R
in roa d and traffic condition s whic h do no t
allow you to maintai n a constan t speed, e.g. in
heav y traffic or on windin g roadsR
on slipper y roa d surfaces. Braking or accel-
erating could caus e th e drive wheels to lose
traction and th e vehicl e could then skidR
when there is poor visibility, e.g. due to fog ,
heav y rain or snow
If there is a chang e of drivers, advise th e ne w
driver of th e speed stored.Driving systems 169
Driving and parking Z

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be shif-
ted into position P automatically.
MAGIC BODY CONTROL
General notes MAGIC BODY CONTROL consists of Active Body
Control (ABC), ROAD SURFACE SCAN as well as
automatic vehicle stabilization in the event of a
crosswind.
Your vehicle automatically adjusts its ride height
to improve driving safety and reduce fuel con-
sumption. The suspension mode is adjusted
according to your selection (sports or comfort),
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
G WARNING
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 adjusting 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.
Select the "Normal" setting for normal road con-
ditions and "Raised" for driving with snow chains
or in particularly poor road conditions.

AIRMATIC
General notes AIRMATIC is an 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 level.
AIRMATIC consists of level setting, level control
and the Adaptive Damping System ADS PLUS.

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.
Vehicle level
Setting the raised vehicle level
It is possible to choose between the "Normal"
and "Raised" vehicle levels. Select the "Normal"

Suspension tuning
General notes The Adaptive Damping System ADS PLUS auto-
matically controls the calibration of the damp-
ers.
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.
i You can choose between the sporty and
comfortable mode. One of the two modes is
always active.182

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.
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 , R or N
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
sp eeds. Range of the sensors 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. overhanging
loads, truck overhangs or loading ramps.
