Lighting117Activation
The high beam assist is activated by
pushing the indicator lever twice with
a speed above 25 mph.
The green control indicator l
illuminates continuously when the
assist is activated, the blue one 7
illuminates when high beam is on.
Control indicator l 3 92.
Deactivation
Push indicator lever once. It is also
deactivated when front fog lights are
switched on.
If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.
If a headlight flash is activated when
the high beam is off, the high beam
assist will stay activated.
High beam assist is always active
after the ignition is switched on.
Intelligent light ranging with
automatic high beam activation
Intelligent light ranging uses the
properties of Bi-Xenon headlights to
extend the light range of the low beam
by up to 400 metres and additionally
activates automatic high beam
without dazzling or disturbing
oncoming or preceding traffic.
High beam is deactivated and the low
beam light range is reduced to avoid
dazzling when the following
restrictions are detected by the front
camera in the windscreen:
● A preceding vehicle is recognised.
● An oncoming vehicle is recognised.● Urban areas are entered.
● It is foggy or snowy.
If there are no restrictions detected,
the system switches back to high
beam.
When the system is active, the front
camera monitors the area ahead of
the vehicle and ensures an optimum
light distribution for maximum driver
vision during almost all conditions.
Intelligent light ranging with automatic high beam activation therefore
reduces the difference between
conventional low and high beam
without drastic changes in light-
range, distribution and intensity.
118LightingA special topographical evaluation
function detects preceding vehicles
on hills or slopes by recognising the
rear light moving ahead. The system
adjusts the height of the light range to
ensure optimum illumination on the
road ahead without dazzling.
Activation
Intelligent light ranging and automatic
high beam activation are switched on together by pushing the indicator
lever twice. They can be switched on
with ignition on.
Automatic high beam activation
operates at a speed above 25 mph
and deactivates below 12 mph.
Intelligent light ranging operates
above 35 mph.
The green control indicator l
illuminates continuously when the
function is activated, the blue one 7
illuminates when high beam switches
on automatically.
Deactivation
Push indicator lever once. It is also
deactivated when front fog lights are
switched on.
Dynamic automatic headlight
levelling
To prevent oncoming traffic fromdazzle, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.Fault in Adaptive forward lighting
system
When the system detects a failure in
the Adaptive forward lighting system,
the system moves to a preset position to avoid dazzling of oncoming traffic.
If this is not possible, the affected
headlight will be automatically
switched off. In any case, one
headlight will stay on. A warning is
displayed in the Driver Information
Centre.
Hazard warning flashers
Operated by pressing ¨.
120LightingParking lights

Reversing lights
The reversing light comes on when
the ignition is on and reverse gear is
selected.
Misted light covers
The inside of the light housing may
mist up briefly in poor, wet and cold weather conditions, in heavy rain or
after washing. The mist disappears
quickly by itself; to help switch on the
headlights.Interior lighting

Battery discharge protection Vehicle battery state of charge
function
The function guarantees longest
vehicle battery life via a generator with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in
two stages and finally switched off:
● auxiliary heater
● heated rear window and mirrors ● heated seats
● fanIn the second stage, a message
which confirms activation of the
vehicle battery discharge protection
will be displayed in the Driver
Information Centre.

136Driving and operatingStarting 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 and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
vehicle battery.
