f flashes for approx. 4 seconds as a
reminder.
To deactivate, use the same

Daytime running lights
Daytime running lights increases
visibility of the vehicle during daylight.
They are switched on automatically
during daytime when engine is
running.
The system switches between
daytime running lights and headlights automatically, depending on the
lighting conditions.
Automatic light control 3 131.LED headlights
LED and Matrix-LED headlights for
low and high beam ensure better
visibility under all conditions.
Matrix-LED headlight contains
beyond that a variety of particular
LEDs in each headlight which
enables the control of different
lighting programmes.
Light distribution and intensity of light
are variably triggered depending on
the lighting conditions, road type and
driving situation. The vehicle adapts
the headlights automatically to the
situation to enable optimal light
performance for the driver. Some
functions of the LED headlights can
be deactivated or activated in the
vehicle personalisation menu. Select
the relevant setting in Settings I

The following lighting functions are
available with light switch in position
AUTO or 9.Town light
Activated automatically at a speed up
to approx. 55 km/h 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. 55 km/h when driving
in rural areas. The illumination of the
current lane and the side of the roadis improved. Oncoming and
preceding vehicles are not dazzled.
142Climate controlPress A/C 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.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit
Autostops.
Stop-start system 3 157.
Air recirculation system nPress n to activate air recirculation
mode, LED is indicated.
Press n 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 A/C.
● Press n for air recirculation
system on.
● Press x for air distribution.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.
Customer information295Operating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● ambient conditions (e.g. temperature, rain sensor,
distance sensor).
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board
the vehicle itself. Control units often
include data storage (including the
vehicle key). This is used to allow information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.Depending on the technical
equipment level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service net-work ( e.g. garages,manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which is read out,
documents the technical condition of
the vehicle or individual components
and assists with fault diagnosis,
compliance with warranty obligations
and quality improvement. This data,
in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the
vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
