Adaptive functions of the DIGITAL LIGHT

qIntelligent Light System function
With this system, the headlamps adapt to the driv- ing and weather situation. It also provides exten-ded functions for improved illumination of theroad.
\bThe availability of the functions is dependenton the country.
The system comprises the following functions:
= Active headlamps (  page 124)
= Cornering light (  page 124)
= Highway mode (  page 125)
= Enhanced fog light function (  page 125)
= Bad weather light (  page 125)
= City lighting (  page 125)
= Topographical compensation (  page 125)
The system is active only when it is dark.

q Active headlamps function
=
The headlamps follow the steering move-
ments.
= Relevant areas are better illuminated during a
journey.
The functions are active when the low beam is
switched on.
Depending on the vehicle\bs equipment, the course of the lane in which you are driving will also beevaluated and the active headlamps function will
adjust the light in advance.

q Cornering light function
The cornering light improves the illumination of
the road over a wide angle in the turning direc-
tion, enabling better visibility on tight bends, for
example. The cornering light will be activated only when low beam is switched on.
The function will be active in the following cases:
= At speeds below 25 mph (40 km/h) when the
turn signal light is switched on or the steeringwheel is turned
= At speeds between 25 mph (40 km/h) and
43 mph (70 km/h) and when the steering
wheel is turned
124Light and visibility

TraPc circle and intersection function: the corner-
ing light will be activated on both sides based on an evaluation of the vehicle\bs current navigation
position. It will remain active until aser the vehicle
has les the traPc circle or intersection.

q Highway mode function (Canada)
Highway mode increases the range and bright-
ness of the cone of light, enabling better visibility.
The function will be active if a highway journey is
detected by means of:
= the vehicle\bs speed
= the multifunction camera
= the navigation system
The function is not active in the following cases:
= at speeds below 50 mph (80 km/h)

q Enhanced fog light function (Canada)
The enhanced fog light function reduces self-glare
and improves the illumination of the edge of the
road.
The function is automatically activated under the following conditions:
= At speeds below 43 mph (70 km/h) and when
the rear fog light is switched on.
The function is automatically deactivated underthe following conditions:
= When speeds greater than 62 mph
(100 km/h) are reached.
= When the rear fog light is switched oM.

q Function of the bad weather light (Canada)
The bad weather light reduces reOections in rainy
conditions by dimming individual areas of the
headlamps. The driver and other road users are dazzled less as a result.

q The city lighting function (Canada)
City lighting improves the illumination of roadsides in urban areas using a broad distribution of light.
The function is active in the following cases:
= At low speeds
= In illuminated parts of urban areas

q Function of the topographical compensation
Based on available map data, the lighting system
responds pre-emptively to diMerent road heights.
This means that the headlamp range remains vir-
tually constant when you are driving on uphill or downhill gradients.Light and visibility125

\bOnly vehicles with a multimedia system withnavigation have this function.

q Assistance functions of the DIGITAL LIGHT
DIGITAL LIGHT visually expands on the driver assistance systems by projecting the assistant
displays in front of the vehicle while it is in
motion. DIGITAL LIGHT can therefore help the
driver in critical situations.
\bThe availability of the functions is dependent on the country.\bThe assistance functions of the DIGITAL
LIGHT are available on-demand (  page 19).
The system will be active in the following cases:
= The light switch is in the X position.
= High beam is switched on.
\bDepending on the country in which you are
currently driving, certain functions may be
disabled due to diMerent legal requirements,
even if they are enabled in the multimedia
system. When you cross a border, the vehicle
will automatically adapt to the applicable requirements.Spotlight
The spotlight function runs in the background and
Oashes the headlamps in four short bursts at per-
sons detected within the lane markings. You will also be made aware of the position of the person by a projected symbol.
The function will be active in the following circum-
stances:
= You are driving outside illuminated areas.
= The system detects a lane marking.
Notes
If TraPc Sign Assist detects a roadworks zone,
the system will provide support as follows:
= A corresponding symbol will be projected onto
the road when you enter a roadworks zone.
Observe the system limitations of TraPc Sign
Assist (  page 207).

Assist (  page 202).
Lane change warning
During assisted lane changes at speeds of at least
19 mph (30 km/h), the course of the lane change
will Oash.
Observe the system limitations of Active Lane
Change Assist (  page 200).
Lane keeping and blind spot warning
At speeds of at least 19 mph (30 km/h), a trian-
gle that indicates a lane correction and its direc-
tion will be projected onto the road in the follow-
ing cases:
= You leave the lane unintentionally.
Observe the system limitations of Active Lane
Keeping Assist (  page 217).

Adaptive Highbeam Assist

qAdaptive Highbeam Assist function
&WARNING Risk of accident despite Adap-
tive Highbeam Assist
Adaptive Highbeam Assist does not react to:
= Road users without lights, e.g. pedestrians
= Road users with poor lighting, e.g. cyclists
= Road users whose lighting is obstructed,
e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users with their own lighting, or may recognize them
too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or will be
activated despite the presence of other road
users.Always observe the road and traPc con-
ditions carefully and switch oM the high
beam in good time.Adaptive Highbeam Assist cannot take into
account road, weather or traPc conditions.
Detection may be restricted in the following
cases:
= in poor visibility, e.g. fog, heavy rain or snow
= if there is dirt on the sensors or the sensors
are obscured
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle\bs lighting to the prevailing light, visibility and traPc conditions.\bAdaptive Highbeam Assist is available on
demand (  page 19).128Light and visibility
