Headlights when driving
abroad The asymmetrical headlight beam
extends visibility at the edge of the
road at the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights to prevent dazzling of oncoming
traffic.
Vehicles with halogen headlight
system
The adjusting screws are located
above the headlight.
Turn the adjusting screws with the
screwdriver clockwise by half a turn.
For deactivation, turn the adjusting
screws anticlockwise by half a turn.
Caution
Have the adjustment of the
headlights checked after
deactivation.
We recommend consulting a
workshop.
Vehicles with adaptive forward
lighting system
1. Key in ignition switch.
2. Pull turn signal lever and hold (headlight flash).
Lighting107
3. Switch on ignition.
4. After approx. 3 seconds, an acoustic signal sounds.
The headlights are aimed
automatically.
Every time the ignition is switched on,
control indicator f flashes as a
reminder for approx. 4 seconds.
For deactivation, operate the same
procedure as described above.
Control indicator f will not flash when
function is deactivated.
Control indicator f 3 89.
Daytime running lights Daytime running lights increase
visibility of the vehicle during daylight.
They are switched on automatically
when ignition is on.Adaptive forward lighting
The Adaptive forward lighting
functions are only available with Bi-
Xenon headlights. Light range, light
distribution and intensity of light are
variably triggered depending on the
light conditions, weather and road
type.
Playstreet lightingActivated automatically at low speed
up to approx. 20 mph. The light beam
is turned at an angle of -5°/3° to the
roadside.
Town lighting Activated automatically at a speed up
to approx. 30 mph and when street
lights are detected by the light sensor.
The light range is reduced by an
extended light distribution.
Country lighting
Activated automatically at a speed
range between approx. 30 and
72 mph. The beam of light and the
brightness is different between the
left and the right side.Motorway lighting
Activated automatically at a speed
above approx. 72 mph and minimal
steering movements. It switches on
after a delay or directly when the vehicle is powerfully accelerated. The
light beam is longer and brighter.
Adverse weather lighting
Activated automatically up to a speed
of approx. 43 mph, when the rain
sensor recognises condensation or the wiper operates continuously. The
range, distribution and light intensity
is regulated variably depending on visibility.
Lighting109
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 remain activated.
High beam assist is always active
after the ignition is switched on.
Dynamic automatic headlight
levelling
To prevent oncoming traffic from dazzle, 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.
Have the cause of the failure
remedied by a workshop as soon as
possible.Hazard warning flashers

Turn and lane-change
signalslever up=right turn signallever down=left turn signal

For three flashes, e.g. when changing
lanes, press the lever until resistance
is felt and then release.
Move the lever to the resistance point
and hold for longer indication.
