LED headlights
LED headlight system contains a
variety of particular LEDs in each
headlight which enables the control of the adaptive forward lighting
functions.
Light distribution and intensity of light
are variably triggered depending on
the lighting conditions, road type and
driving situation. The vehicle adapts
the headlights automatically to the
situation to enable optimal light
performance for the driver.
Some adaptive forward lighting
functions of the LED headlights can
be deactivated or activated in thevehicle personalisation menu. Select
the relevant setting in Settings, I
Vehicle in the Info Display.
Vehicle personalisation 3 105.
The lighting functions are only
available with light switch in position
AUTO .
Country light
Activated automatically at a speed
between 34 mph and 71 mph when
driving in rural areas. The illumination of the current lane and the side of theroad is improved. Oncoming and
preceding vehicles are not dazzled.
Page 118 of 271

116LightingMotorway light
Activated automatically at a speed
above 71 mph. Illumination is
adapted to the higher speed driven on
motorways. If there is no oncoming
traffic, the visibility on the side of the
vehicle is increased. The visibility
range raises from 70 m to 140 m
allowing distant objects to be
recognised across the entire width of
the road.
Town light
Activated automatically at a speed up to approx. 34 mph and in situations
with exterior ambient light. The light is
wide and symmetrical. If the speed is
below 19 mph, the headlamps are
slightly swiveled to the outside to
allow an earlier recognition of
pedestrians and objects on each side
of the road. A special beam pattern is
designed to avoid glare for other road users.
Corner light
Activated at a speed of up to 25 mph
when turning off. The light consists of particular LEDs which illuminate the
direction of travel. These LEDs are
triggered depending on the steering
angle or the activation of the turn lights.
Adverse weather light
Controlled by wiper or rain sensor.
The wide light distribution – slightly
swiveled to the outside – enables
improved orientation at the edge of
the road. The intensity of the light in
the far distance is increased in order
to recognise objects and markings on
the right road side and obstacles on
the lane despite the weather
condition. By lowering the reflection
on wet roads the oncoming traffic is less dazzled. Adverse weather light is activated up to a speed to 43 mph.
Curve light
Page 119 of 271

Lighting117Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 25 mph to 43 mph.
High beam assist This feature allows the high beam to
function as main driving light at night.
The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Each LED on
right or left side can be triggered or
faded out particularly according to the traffic situation. This gives the best
light distribution without dazzling
other road users. Once activated,
high beam assist remains active and
switches high beam on and off
depending on surrounding
conditions. The latest setting of the
high beam assist will remain after the ignition is switched on again.High beam assist includes a special
motorway mode. When driving faster
than 71 mph on motorways, the light
beam becomes smaller to avoid
dazzling of oncoming traffic. When
following vehicles ahead or passing,
dazzling for these vehicles is
reduced.
Activation
Activate the high beam assist by
pressing f. The LED of the button
illuminates if the high beam assist is
activated. High beam is switched on automatically at a speed above
15 mph . High beam is switched off at
a speed below 9 mph, but high beam
assist remains active.
The green control indicator f
illuminates continuously when the
high beam assist is activated, the blue 7 illuminates when high beam is on.
Control indicator f 3 98, 7 3 98.
Pushing left steering wheel stalk once
switches on manual high beam
without high beam assist.
High beam assist switches
automatically to low beam when:
● Driving in urban areas.
● Camera detects heavy fog.
● Front or rear fog lights are switched on.
If there are no restrictions detected, the system switches back to high
beam.
Deactivation
Deactivate the high beam assist by
pressing f.

the high beam assist is activated and
low beam is on, the high beam assist will be deactivated. The system
changes to high beam.
If a headlight flash is activated when
the high beam assist is activated and
high beam is on, the high beam assist will be deactivated. The system
changes to low beam.
To reactivate the high beam assist,
flash the headlights again.
Fault in LED headlight system
When the system detects a failure in
the LED headlight system, it selects a preset position to avoid dazzling of
oncoming traffic. A warning is
displayed in the Driver Information
Centre.Hazard warning flashers
Operated by pressing ¨.
When braking in an emergency, the
hazard warning flashers are switched
on automatically depending on the
force of deceleration. They are

manually moved back to its neutral
position.
