112LightingParticular LEDs, based on steeringangle 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 activates the high beam
at night when the vehicle speed is
faster than 15 mph.
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 97, 7 3 97.
Pushing left indicator lever 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.

130Driving and operatingDriving hints
Control of the vehicle
Never coast with engine not
running
Many systems will not function in this situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 134.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.Steering
If power steering assist is lost
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.
