Lighting139The following lighting functions are
available with light switch in position
AUTO or 9.
Town light
Activated automatically at a speed up to approx. 55 km/h and in situations
with exterior ambient light. The light is
wide and symmetrical. A special
beam pattern is designed to avoid
glare for other road users.
Country light
Activated automatically at a speed
above approx. 55 km/h when driving
in rural areas. The illumination of the
current lane and the side of the road is improved. Oncoming and
preceding vehicles are not dazzled.
Curve light
Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 40 km/h to 70 km/h and
reacts to steering angle.
Corner light
When turning off, depending on the
steering angle and the turn signal light, particular LEDs are triggered
which illuminate the direction of
travel. It is activated up to a speed of
40 km/h.
Reverse parking function To assist driver's orientation when
parking, both corner lights and
reversing light illuminate when
headlights are on and reverse gear is
engaged. They remain illuminated for
a short time after disengaging reverse gear or until driving faster than
7 km/h in a forward gear.
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 particulary according to the
traffic situation. This gives the best
light distribution without glaring other
road users. Once activated, high
beam assist remains active and
switches high beam on and off
depending on surrounding
140Lightingconditions. 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 115 km/h on motorways, the light
beam becomes smaller to avoid
glaring of oncoming traffic. When
following vehicles ahead or passing,
mirror glaring for these vehicles is
reduced.
