on if: R
an air bag is deployed or R
the vehicle decelerates rapidly from a speed
of above 45 mph (70 km/h) and comes to a
standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
i The hazard warning lamps still operate 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, cornering
light function, highway mode and extended
range fog lamps. The system is only active when
it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
( Y
page 238).
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 driving. This
allows you to recognize pedestrians, cyclists
and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in
which you are driving and adjusts the light in
advance.
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 only be
activated when the low-beam headlamps are
switched on.
Active: R
if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel R
if you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Cornering light function with traffic circle
function:112
Exterior lighting
Lights and windshield wipers

The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Highway mode Highway 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 fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the road.
Active: if you are driving at speeds below
40 mph (70 km/ h) and you switch on the rear
fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 60 mph (10 0 km/ h) or if you
switch off the rear fog lamp
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 low-beam headlamps.
Active: when driving at speeds no faster than
30 mph (50 km/h) and the off-road program
selector wheel is in position 1 or 2.
Not active: when driving at speeds above
30 mph (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. Adaptive Highbeam Assist
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 head-
lamps 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
detects any other vehicles, it reactivates the
high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
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 a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is
a risk 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 con-
ditions.
In particular, the detection of obstacles can be
impaired if: R
poor visibility, e.g. due to fog, heavy rain or
snow R
dirt on the sensors or the sensors are
obscuredExterior lighting 113
