Lighting121Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Control indicator f 3 92.
Corner lighting
On tight bends or when turning off,
depending on the steering angle or
the turn signal light, an additional left
or right reflector is switched on which illuminates the road at a right angle to
the direction of travel. It is activated
up to a speed of 40 km/h.
Control indicator f 3 92.
Reversing function
If the headlights are on and reverse
gear is engaged, both corner lights
are switched on. They remain
illuminated for 20 seconds after
disengaging reverse gear or until
driving faster than 17 km/h in a
forward gear.
High Beam Assist
This feature allows high beam as
main driving light by night and when
vehicle speed is faster than 40 km/h.
It switches to low beam when: ● The camera in the windscreen detects the lights of oncoming or
preceding vehicles.
● The vehicle speed is slower than
20 km/h.
● It is foggy or snowy.
● Driving in urban areas.
If there are no restrictions detected, the system switches back to high
beam.Activation
The high beam assist is activated by
pushing the indicator lever twice with
a speed above 40 km/h.
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.

operates at a speed above 40 km/h
and deactivates below 20 km/h.
Intelligent light ranging operates
above 55 km/h.
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 headlightlevelling
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.
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 ¨.
In the event of an accident with airbag
deployment the hazard warning
flashers are activated automatically.

Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:

Cooling n
Press n to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
