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. 112

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

! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratch the wind-
screen.
For this reason, you shoul dalways switch
off the windscreen wipers in dry weather.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wiper to wipe more frequently. Replacing the wiper blades
Important safety notes G
WARNING
The wiper arms could star tmoving and cause
an injury if you leave the windscreen wipers
switched on.
Remove the key from the ignition lock before
replacing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by aqualified
specialist workshop, e.g. at a Mercedes-
Benz Service Centre.

On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain a preset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC doe snot
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way
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.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. You will find further
information under "Radar sensor system"
