General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with lights switched on
even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and voluntary recommendations. Driving abroad
Vehicles with halogen headlamps It is not necessary to switch your headlamps to
symmetrical dipped beam when driving in coun- tries where vehicles are driven on the opposite
side of the road to the country in which the vehi-
cle is registered. Legal requirements are fulfilled
without switching the headlamps to symmetri-
cal dipped beam.
Vehicles with Intelligent Light System It is necessary to switch your headlamps to sym-
metrical dipped beam before crossing the bor-
der into countries where vehicles are driven on
the opposite side of the road. This prevents
oncoming traffic from being dazzled.
You can switch the headlamps to symmetrical or
asymmetrical dipped beam using the "dipped-
beam headlamps for driving on the right/left"
function via the on-board computer
(Y page 244). This must be switched back to
asymmetrical dipped beam upon your return.
Symmetrical lights do not illuminate as large an
area of the edge of the carriageway. In this case,
"highway mode" and "extended-range fog
lamps" are not available. Setting the exterior lighting

off: press the :button.
All the indicator lamps will flash when the
hazard warning lamps are switched on. If you
now switch on an indicator lamp using the
combination switch, only the indicator lamp
on the corresponding side of the vehicle will
flash.
The hazard warning lamps switch on automati-
cally if:
R an airbag has been triggered or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps to suit the prevailing
driving and weather conditions. It offers
advanced functions for improved illumination of the road surface, e.g. depending on the vehicle
speed or weather conditions. The system
includes the active light function, cornering light
function, motorway mode and extended-range
fog lamps. The system is active only when it is
dark.
You can activate/deactivate the Intelligent
Intelligent
Light System Light System function using the on-board
computer (Y page 243).
Active light function The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can be acti-
vated only when the dipped-beam headlamps
are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both
sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Motorway mode Motorway mode increases the range of the
beam.
Active:if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended-range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear fog lamp. 118

Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps 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 switches on
the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditionsand switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions. In particular, the detection of obstacles can be
impaired in the case of:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or obscured sensors

General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed Exterior lighting
119Lights and windscreen wipers Z
Page 123 of 389

past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main- beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by the dipped-beam headlamps.
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 switches on
the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.

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
(Y page 68). Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Shift to a lower gear in
good time on long and steep downhill gradients.
Take particular note of this when driving a laden vehicle and when towing a trailer. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady speed for a prolonged period. You can store anyroad speed above 30 km/h. If you have set a
permanent limit speed, you cannot set the
speed any higher than the fixed limit speed
(Y page 177).
Important safety notes Cruise control can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. Cruise control can- not take into account road, weather or traffic
conditions. Cruise control is only an aid. You are
responsible for maintaining a safe distance from the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane. Do not use cruise control:
R in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on smooth or slippery roads. Braking or accel-
erating can 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.

DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front. Vehicles are detected with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. 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 overheat- ing and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of
collision with the vehicle in front, you will be
warned visually and audibly. Without your inter- vention, DISTRONIC PLUS cannot prevent a col-
lision. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately to increase the distance to the vehicle in front,
or take evasive action, provided it is safe to do
so.
DISTRONIC PLUS operates in the speed range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions. In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes your vehicle with up to 50 %of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
DISTRONIC PLUS can neither reduce the risk of
an accident if you fail to adapt your driving style
nor override the laws of physics. DISTRONIC
PLUS cannot take into account road, weather or traffic conditions. DISTRONIC PLUS is only an
aid. You are responsible for maintaining a safe
distance, for vehicle speed, for braking in good
time and for staying in lane.
Do not use DISTRONIC PLUS:
R in traffic conditions that do not allow you to
maintain a constant speed, e.g. in heavy traf-
fic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can 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
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. 178
Driving systemsDriving and parking
Page 188 of 389

towards the edge of the carriageway, your vehi-
cle could come into contact with the kerb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
you have intentionally driven over a lane mark-
ing, can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not
leave the lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow

The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering Assist and Stop&Go Pilot are automatically
active again. Steering Assist and Stop&Go Pilot cannot pro-
vide assistance in the following situations:
R on very sharp corners
R when a loss of tyre pressure or a defective
tyre has been detected and displayed
Also observe the important safety notes for
DISTRONIC PLUS (Y page 178).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears on the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Assist
and Stop&Go Pilot switch to passive mode.
DISTRONIC PLUS remains activated.
