General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and self-imposed obligations. Driving abroad
General notes If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam as soon as possible
after crossing the border. This prevents oncom-
ing traffic from being dazzled. Symmetrical
lights do not illuminate as large an area of the
edge of the carriageway.
Vehicles with halogen headlamps X
Turn cap :anti-clockwise and remove it.
X Push switchover lever ;down.
X Replace cap :and turn it clockwise.
Convert the headlamps back to asymmetrical
dipped beam as soon as possible after returning across the border.
Vehicles with Intelligent Light System X
Before crossing the border, set the head-
lamps to symmetrical dipped beam and after
returning back to asymmetrical dipped beam via the "Dipped-beam headlamps for driving
on the right/left" function in the on-board
computer (Y page 252). If the headlamps are converted to symmetrical
dipped beam, the "motorway mode" and "exten-
ded range foglamps" functions are not available. Setting the exterior lighting
Setting options Exterior lighting can be set using:
R the light switch
R headlamp range control (vehicles with halo-
gen headlamps only) (Y page 122)
R the combination switch (Y page 122)

The hazard warning lamps switch on automati-
cally if:
R an airbag is deployed 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.
i The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, corneringlight function, motorway mode and extended
range foglamps. The system is only active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com-
puter (Y page 252).
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.
Active: when the lights are switched on.
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.
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 1,000 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 foglamps 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 foglamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear foglamp.
Off-road lights The off-road lights facilitate the early recogni-
tion of objects/obstacles when driving off-road
thanks to a symmetrical, wider and brighter dis-
tribution of light from the dipped-beam head-
lamps.
Active: when driving at speeds no faster than
50 km/h and the off-road program selector
wheel is in position 1 or 2.
Not active: when driving at speeds above
50 km/h.
When the off-road lights are switched on, the
cornering light function is permanently activa-
ted, the active light function is deactivated and
the headlamp range control is set to static
mode. Exterior lighting

Adaptive Highbeam Assist Plus
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
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 reflections
is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Vehicles with drive program S+(Sport Plus): the
speed at which Adaptive Highbeam Assist Plus
switches between full beam and dipped beam is
increased when the drive program is switched
on.
Important safety notes G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent. Always carefully observe the traffic conditions
and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
In particular, the detection of obstacles can be
restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

lamps.
At speeds above approx.25 km/h: the
headlamp range is automatically controlled
according to the distance to other road users.
At speeds above approx.30 km/h:
R if no other road users are detected, the
main-beam headlamps are automatically
switched on
R if other road users are detected, the partial
main-beam headlamps are automatically
switched on
The K indicator lamp in the instrument
cluster also lights up.

Do not use cruise control:
R in road and traffic conditions which 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.

Distance Pilot DISTRONIC with Steering
Pilot General notes
Distance Pilot DISTRONIC with Steering Pilot
aids you in keeping the vehicle in the centre of
the driving lane by means of moderate steering
interventions in a speed range from
0 - 200 km/h.
It monitors the area in front of your vehicle by
means of camera system :at the top of the
windscreen.
In a speed range from 0 - 60 km/h, the advanced automatic pulling away function focuses on thevehicle in front, taking into account lane mark-
ings, e.g. when following vehicles in a traffic jam.
At speeds of more than 60 km/h, Steering Pilot
focuses on detected lane markings (left and
right), only focusing on the vehicle in front if
detected lane markings are not present.
If these conditions are not present, Steering
Pilot cannot provide assistance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes If you fail to adapt your driving style, Distance
Pilot DISTRONIC and Steering Pilot can neither
reduce the risk of an accident nor override the
laws of physics. It cannot take into account
road, weather or traffic conditions. Distance
Pilot DISTRONIC with Steering Pilot 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 lane.
Distance Pilot DISTRONIC with Steering Pilot
does not detect road and traffic conditions and
does not detect all road users. If you are follow-
ing a vehicle that is driving towards the edge of the carriageway, your vehicle 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 Pilot cannot
continuously keep your vehicle in lane. In somecases, the steering intervention is not sufficientto 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 support offered by the system may be
impaired if:
R visibility is poor, e.g. due to insufficient illu-
mination of the road, or due to snow, rain, fog
or spray
R there is 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
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the road
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
i After you have finished changing lanes,
Steering Pilot is automatically active once
more. Driving syste
