In the Ãposition, the main-beam head-
lamps are only switched on when it is dark

Vehicles with Adaptive Highbeam Assist
Plus: when Adaptive Highbeam Assist Plus is
activated, it automatically controls activation and deactivation of the main-beam head-
lamps (Y page 143).
Headlamp flasher X
To switch on: turn the key in the ignition
lock to position 1or 2, or start the engine.
X Pull the combination switch in the direction
of arrow =. Hazard warning lamps X
To switch on the hazard warning lamps:
press button :.
All turn signals flash. If you now switch on a turn signal using the combination switch,
only the turn signal lamp on the corre-
sponding side of the vehicle will flash.
X To switch off the hazard warning lamps:
press button :.
The hazard warning lamps switch on auto-
matically 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 auto-
matically if the vehicle reaches a speed of
above 10 km/h again after a full brake appli- cation.
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 illu-
mination 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,
extended range foglamps and off-road lights.
The system is only active when it is dark.
You can activate or deactivate the "Intelligent Light System" function using the on-board
computer (Y page 331). Exterior lighting
141Lights and windscreen wipers Z
Extended range foglamps
The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
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
driving at speeds above 100 km/h or if you
switch off the rear foglamp.
Off-road lights The off-road lights facilitate the early recog-
nition of objects/obstacles when driving off-
road thanks to a symmetrical, wider and
brighter distribution of light from the dipped- beam headlamps.
Active: at speeds below 50 km/h.
The off-road lights are only active with the
following off-road programs:
R Slippery
R Off-road
R Travelling uphill
R Rocking free
Not active: at speeds above 50 km/h.
When the off-road lights are switched on, the cornering light function is permanently acti-
vated, the active light function is deactivated
and the headlamp range control is set to
static mode. Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam head-
lamps.
Partial main-beam illumination is a form of
illumination whereby the main beam is direc-
ted 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 head-
lamps.
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
traffic signs, the lights are automatically dim-
med 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. Exterior lighting

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 condi-
tions. Adaptive Highbeam Assist Plus is only
an aid. You are responsible for adjusting the
vehicle's lighting to the prevailing light, visi-
bility 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 if the sensors are
obscured
Switching Adaptive Highbeam Assist
Plus on/off X
To switch on: turn the light switch to the
à position.
X Press the combination switch beyond the
pressure point in the direction of arrow :.
The _ indicator lamp in the multifunc-
tion display lights up when it is dark and the
light sensor switches on the dipped-beam
headlamps.
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 par-
tial main-beam headlamps are automat-
ically switched on.
The K indicator lamp in the instrument
cluster also lights up.
At speeds below approx. 25 km/h or
when there is sufficient street lighting:
R The partial main-beam headlamps are
switched off automatically.
R The main-beam headlamps are switched
off automatically.
The K indicator lamp in the instrument
cluster goes out. The _indicator lamp
in the multifunction display remains lit.
X To switch off: move the combination
switch back to its normal position or move the light switch to another position.
The _ indicator lamp in the multifunc-
tion display goes out. Headlamps misted up on the inside
Certain climatic and physical conditions may
cause moisture to form in the headlamp. This
