● When the light switch is in position or
. WARNING
The side lights or daytime running lights are
not bright
enough to illuminate the road
ahead and to ensure that other road users are
able to see you.
● Always use your dipped beam head lights if
it i
s raining or if visibility is poor. WARNING
If the headlights are set too high and not
u sed c
orrectly, there is a risk of dazzling or
distracting other road users. This could result
in a serious accident.
● Always make sure that the headlights are
corr
ectly adjusted. Daytime running lights
The daytime running lights consist of individ-
ual
lights, int
egrated in the front headlights.
By connecting the daytime running lights,
these lights are switched on 1)

The d a
ytime running lights switch on every
time the ignition is switched on, if the switch
is in positions or , according to the level
of exterior lighting. When the light switch is in position
, a
light
sensor automatically switches dipped
beam on and off (including the control and
instrument lighting) or the daytime running
lights depending on the level of exterior
lighting. WARNING
● Nev er driv
e with daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● On vehicles with rear lights with bulbs,
when activatin
g the daytime running light
the rear lights are not switched on. A vehicle
which does not have the rear lights on may
not be visible to other drivers in the dark-
ness, in the case of heavy rain or in condi-
tions of poor visibility. Turn signal and main beam lever

Convenience turn signals
F or the c
onvenience turn signals, move the
lever as far as possible upwards or down-
wards and release the lever. The turn signal
will flash three times.
The convenience turn signals are activated
and deactivated in the Easy Connect system
via the key and the
Set
up function button
› ›
› page 108.
In vehicles that do not have the correspond-
ing menu, this function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
f or
getting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
ch
ange lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, o
vertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
c ident
s and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c
onvenience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is
switched on. The hazard warning
lights also work when the ignition is switch-
ed off.
● If a trailer turn signal malfunctions, the
contr
ol lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam he
adlights can only be
switched on if the dipped beam headlights
are already on.
● In cold or damp weather conditions, the
hea
dlights, tail lights and turn signals may
mist up inside temporarily. This is normal and
in no way effects the useful life of the vehicle
lighting system. Automatic dipped beam control

Lights and visibility
When the system is activated and the camera
det ects
other vehicles that may be dazzled,
the main beam is automatically switched off.
Otherwise, the main beam is automatically
switched on.
The main beam assist generally detects illu-
minated areas and deactivates the main
beam when passing through a town, for ex-
ample.
Switching the main beam assist on and off
Func-
tionUse
Activate:
– Switch the ignition on and turn the light
switch to position .
– From the base position, move the main
beam and turn signal lever forwards
››› page 131. When the warning lamp
is
displayed on the instrument panel display,
the main beam assist is switched on.
To switch system off:
– Switch off the ignition.
– OR: turn the light switch to a different po-
sition to
››› page 131.
– OR: with main beam on, move the main
beam and turn signal lever backwards.
– OR: move the main beam and turn the
signal lever forwards to manually switch
the main beam on. The main beam assist
will then be deactivated. Malfunctions
The f
o
llowing conditions may prevent the
main beam headlight control from turning off the headlights in time or from turning off al-
tog
ether:
● In poorly lit towns with highly reflective
sign
s.
● Other insufficiently lit road users (such as
pedes
trians or cyclists).
● On tight bends and steep slopes (bumps)
and when oncomin
g vehicles are partially ob-
scured.
● When the drivers of other oncoming vehi-
cl
es (such as a truck) can see over a guard
rail in the centre of the road.
● If the camera is damaged or the power sup-
ply
is cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of
the camer
a.
● When the field of vision of the camera is
mis
ted up, dirty or covered by stickers, snow,
ice, etc. WARNING
The convenience features of the main beam
a s
sist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam
and ad
apting it to the light, visibility and traf-
fic conditions. ●
It i
s possible that the main beam headlight
control does not recognise all driving situa-
tions and is limited under certain circumstan-
ces.
● When the field of vision of the camera is
dirty
, covered or damaged, operation of the
main beam control may be affected. This also
applies when changes are made to the vehi-
cle lighting system, for example, if additional
headlights are installed. CAUTION
To avoid affecting the operation of the sys-
t em, t
ake the following points into considera-
tion:
● Clean the field of vision of the camera regu-
larly
and make sure it is free of snow and ice.
● Do not cover the field of vision of the cam-
era.
● Chec
k that the windscreen is not damaged
in the are
a of the field of vision of the camera. Note
Main beam and headlight flasher can be
t urned on and off
manually at any time with

6. Use the warning triangle to draw the atten- tion of other r
oad users to your vehicle.
7. Always take the vehicle key with you when you l
eave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The ri sk
of an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic c
onverter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
a
l
s, for example dry grass or spilt petrol. This
could start a fire. Note
● The b att
ery will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
sc
ribed here is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right
or l
ef
t turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
sw
it
ch in position , when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially. Motorway light* The motorway light is available on vehicles
equip
ped w
ith full-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when goin
g above 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when r educ
ing the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”.
