WARNING
When th eligh tswitc hiss et to 000C,t helow-
beam headlamp smay not be switche don

causes of poor visibility due to th eweather
conditions such as spray. Ther eisarisk of an

In such situations, tur nthe light switch to
0005.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
000C is the favored light switch setting. The
light settingisa utomatically selected
according to the brightness of the ambient
light (exception: poor visibility due to weather
conditionss uch as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
R With the engine running: if you have
activated the daytime running lamps
function via the on-board computer, the
daytime running lamps or the low-beam
headlamps and parking lamps are switched
on or off automatically depending on the
brightness of the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to 000C.
The daytime running lamps improve the
visibility of your vehicle during the day. The
daytime running lamps function is required by
law in Canada.
When the engine is running and the vehicle is
stationary: if you move the selector lever from
ad rive position to P,the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to 000F,the daytime
running lamps and parking lamps switch on. If the engine is running and you turn the light
switch to
0005,the manual settings take
precedence over the daytime running lamps.
Low-beam headlamps
Even if the light sensor does not detect that
it is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the
0005 position. This is aparticularly useful
function in the event of rain and fog.
X To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
X Turn the light switch to 0005.

instrumentc luster lightsup.
Front fog lamps
In conditions where visibilit yispoor due to
fog, sno worrain, the fog lamps improve
visibilit yaswell as making it easier for other
road users to see you. They can be operated
together with the parking lamps or together
with the parking lamps and low-beam
headlamps.
X To switch on th efront fog lamps: turn
the SmartKey in the ignition lock to position
2 or start the engine.
X Turn the light switc hto0005or000C.

Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognize
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 abarrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognizet hem too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or activated regardless. There is arisk of an
accident.
Always carefully observe the traffic conditions
and switch off the high-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 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 the sensors are
obscured
General notes You can use this function to set the
headlamps to change between low beam and
high beam automatically
.The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detectsa ny other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel. 108

General notes DISTRONIC PLUS regulates the speed and
automatically 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
alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevent sthe brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detect sthat there is arisk
of ac ollision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot
prevent acollision without your intervention. 162
Driving systemsDriving and parking

An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster .Brake immediatel yin
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONI CPLUStoa ssist you, the radar
sensor system must be operational.
DISTRONIC PLUS is automatically
deactivated if:
R you are driving slower than 15 mph
(25 km/h) and there is no longer avehicle
in front or
R the vehicle in front is no longer detected
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h) .Ifa
vehicle is driving in front of you, it operates in
the speed range between 0mph (0 km/h) and
120 mph (200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detector softhe
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
question sare asked about this.

WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g.
stopped or parked vehicles
R oncominga nd crossing traffic
As aresult, DISTRONIC PLUS may neither give
warnings nor interveneins uch situations.
There is arisk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly
identify other road users and complex traffic
situations.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
R accelerate unexpectedly
There is arisk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS. G
WARNING
DISTRONIC PLUS brakes your vehicle with up
to 40% of the maximum braking force. If this
braking force is insufficient, DISTRONIC PLUS
warns you visuallya nd audibly. There is arisk
of an accident.
In such cases, apply the brakes yourself and
try to take evasive action. Driving systems

Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Brakin gor
accelerating could 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
vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else

R snow or heavy rain
R interferenc ebyother radar sources
R strongr adar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detect sa

Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting
aparking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
