automatic light control is active.
Control indicator 8 3 99.
Lighting117to recognise objects and markings on
the front passenger 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 70 km/h.
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.
High beam assist This feature activates the high beam
at night when the vehicle speed is
faster than 25 km/h.
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 115 km/h 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
25 km/h. High beam is switched off at a speed below 15 km/h, but high
beam assist remains active.
The green control indicator f
illuminates continuously when the
high beam assist is activated, the blue

steering). Driving in this manner is a danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 139.
Pedals

because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and enginge oil evaporating off the exhaust system.Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and
engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.
