Lighting135The following lighting functions are
available with light switch in position
AUTO or 9.
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. A special
beam pattern is designed to avoid
glare for other road users.
Country light
Activated automatically at a speed
above approx. 34 mph 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 25 mph to 43 mph 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
25 mph.
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
4 mph in a forward gear.
High beam assistThis 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

154Driving 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 3 159.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
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 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 diesel particle filter may take
place more often.
Diesel particle filter 3 164.
Autostop may be inhibited to allow for
charging of the vehicle battery.
