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 235).
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.
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 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. 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. Exterior lighting

! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid. !
If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. 1

Driving with DISTRONIC PLUS
Pulling away and driving
X To pull away with DISTRONIC PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X Accelerate briefly.
The vehicle pulls away and adapts its speed to
that of the vehicle in front. If no vehicle is
detected in front, the vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If DISTRONIC PLUS does not detect a vehicle in
front, the system operates like cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes the vehicle. In
this way, the specified minimum distance you
have selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it accelerates the vehicle to the
set speed.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style when you have selected the Sor S+ drive pro-
gram (Y page 148). Acceleration behind the
vehicle in front or to the set speed is then notice- ably more dynamic. If you have selected the Cor
E drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you in the following situations:
R You are driving at a speed greater than
70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang- ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small. Vehicles with COMAND Online multimedia
system: when you change lanes, DISTRONIC
PLUS monitors the right lane in the case of left-
side traffic or the left lane in the case of right-
side traffic.
Vehicles with Audio 20 multimedia system:
when you change lanes, DISTRONIC PLUS mon- itors the left lane on left-hand-drive vehicles or
the right lane on right-hand-drive vehicles.
Road and traffic conditions The following function is available only in vehi-
cles with the Driving Assistance Plus package.
The function is not operational in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations.
This is the case if, while you are following a vehi-
cle, DISTRONIC PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
R approach a tollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler-
ate. This is based on the current map data in the navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
of more than 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles in
the adjacent lane to the left.
Prevention of overtaking on the right applies to
countries where traffic drives on the right. In
countries where traffic drives on the left, over-
taking on the left is prevented accordingly. 174

DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle in
the centre of the driving lane by means of mod-
erate steering interventions in a speed range
from 0–200 km/h.
It monitors the area in front of your vehicle by
means of multifunction camera :, at the top of
the windscreen.
In a speed range from 0–60 km/h, Stop&Go
Pilot focuses on the vehicle in front, taking into
account lane markings, e.g. when you are fol-
lowing vehicles in a traffic jam.
At speeds of more than 60 km/h, Steering
Assist 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
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notesDISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. It cannot take into account road, weather or traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay- ing in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you are following a vehicle that is driving 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
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 roadway
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. 178
Driving syste
msDriving and parking

Active Parking Assist will detect only parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle
i Note that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You will need to judge whether your vehicle will fit in
the parking space.
When driving at speeds below 30 km/h, you will
see parking symbol ;as a status indicator in
the instrument cluster. When a parking space
has been detected, an arrow towards the right or the left also appears. Active Parking Assist dis-
plays only parking spaces on the front-
passenger side as standard. Parking spaces on
the driver's side are displayed as soon as the
turn signal on the driver's side is activated.
When parking on the driver's side, this must
remain activated until you confirm the use of
Active Parking Assist by pressing the abut-
ton on the multifunction steering wheel. The
system automatically determines whether the
parking space is parallel or at right angles to the
direction of travel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 m
away from it.
