Lighting121AFL-LED lighting functionsAFL-LED lighting functions are activeautomatically with light switch in
position AUTO. AFL-LED includes
following functions:
● curve and cornering lights
● town light
● country light
● motorway light
● high beam assist
● reverse parking function
● eco mode
● dynamic automatic headlight levelling
Curve and cornering lights
On tight bends or when turning off,
depending on the steering angle or
the indicator light signal, an additional left or right reflector is switched on
which illuminates the road in the
direction of travel. It is activated up to
a speed of 70 km/h.
Town light
Activated automatically at a speed upto approx. 55 km/h. In situations with
exterior ambient light both cornering lights are switched on with reduced
intensity. The light is wide and
symmetrical.
Country light
Activated automatically at a speed of
approx. 55 km/h. The beam of light
and the brightness is different
between the left and the right side.
High beam assist
This feature allows high beam to
function as the main driving light at
night and when vehicle speed
exceeds 40 km/h.
It switches automatically to low beam
when:
● The camera or a sensor in the windscreen detects the lights of
oncoming or preceding vehicles.
● The vehicle speed drops below 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.

In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n:cooling4:air recirculation
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 above a
specific level. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit Autostops.
Stop-start system 3 139.
Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.

Note
If V is pressed while the engine is
running, an Autostop will be inhibited
until V is pressed again.
If l is pressed with the fan switched
on and the engine running, an
Autostop will be inhibited until l is
pressed again or until the fan is
switched off.
If V is pressed while the engine is
in an Autostop, the engine will restart automatically.If l is pressed with the fan switched

Each change of settings is shown in
the Info Display for a few seconds.
The electronic climate control system
is only fully operational when the
