Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

specialist workshops (Y page 28).Exterior lighting
Important safety notes
Fo rreasons of safety, Mercedes-Benzr ecom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Notes on driving abroad
Convert to symmetrical dipped beam
when driving abroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is reg-
istered. This prevents glare to oncoming traf-
fic. Symmetrical lights do not illuminate as
large an area of the edge of the carriageway.
Convert the headlamps as close to the border
as possible before driving in these countries
(Y page 240).
Convert to asymmetrical dipped beam
after returning: convert the headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 240). If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions (Intelli-
gent Light System) are not available. Light switch

The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R if you are driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steering wheel being turned.
R if you are driving at speeds between
40 km/h and 70 km/h ,the cornering light
function is activated by the steering wheel
being turned.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes.
Motorway mode Motorway mode increases the range of the
beam.
Active:
R
if you are driving at speeds above
110 km/h and do not make any large steer-
ing movements for 1000 m
R if you are driving at speeds above
130 km/h
Not active: if you are driving at speeds below
80 km/h following activation. Extended range foglamps
The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active:
if you are driving at speeds below
70 km/h and you switch on the rear foglamp
Not active: if you are driving at speeds above
100 km/h or if you switch off the rear foglamp
following activation Adaptive Highbeam Assist
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically .The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. 122

pressure point in the direction of
arrow :(Ypage 120).
If it is dark and the light sensor activates
the dipped-beam headlamps, the _
indicator lamp in the instrument cluster
lights up.
If you are driving at speeds above
45 km/h:
the headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
55 km/h and no other road users are rec-
ognised:
the main-beam headlamps are switched on
automatically. The Kindicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
45 km/h or other road users are recog-
nised or the roads are adequately lit:
the main-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrument cluster goes out. The _indicator lamp in the instrument cluster
stays on.
X To deactivate: move the combination
switch back to its normal position.

cluster goes out. G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourselfa nd others. Alway sobserve traffic
conditions and, if necessary, dip the lights
manually. Headlamps misted up inside
The headlamps may mist up on the inside if
there is high atmospheric humidity. Exterior lighting

High-performance brake system for
AMG vehicles The high-performance brake system is
designed for heavy loads. This may lead to
noise when braking. This willd epend on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain further informa-
tion about this from your Mercedes-Benz
Service Centre. Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R
you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully.
Driving on flooded roads If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R
the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans-
mission. Winter driving
General notes G
WARNING
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as
long as the engine is running. Otherwise, poi-
sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficien tfresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind. Driving tips

DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy .The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 389).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 242) and operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in front of you, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4 m/s 2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detects a risk of collision
with avehicle in front, an intermittent warning
tone sounds. In addition, the ·distance warning lamp in the instrument cluster lights
up. Brake to avoid a collision.

Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others.
ATTENTIO NASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R driving conditions, e.g. time, driving time
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong sid ewind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND Online
or making a telephone call with it Driving systems
