184Driving and operatingAt speeds below 37 mph the system
is inoperable.
Fault
In the event of a fault, C appears in
the instrument panel, accompanied
by a display message and a warning
chime. Contact a dealer or a qualified
workshop to have the system
checked.
System limitations The system performance may not
operate properly when:
● Vehicle speed is below 37 mph.
● Windscreen is not clean or affected by foreign objects, e.g.
stickers.
● Driving on winding or hilly roads.
● During nighttime driving.
● Adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign objects, e.g.
stickers.● The sun is shining directly into the camera lens.
● Close vehicles ahead.
● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
Lane keep assist Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn
steering wheel in same direction, if
system steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.When the system steers to correct the trajectory of the vehicle, a flashes
yellow in the instrument cluster.
A warning message in the Driver
Information Centre accompanied by a warning chime alerts the driver when
immediate driver´s action is required.
Unintended lane departure is not assumed by the system when the turn lights are operated and during
20 seconds after turn lights have been switched off.
Notice
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fullfilled:
● vehicle speed must be between 40 mph and 112 mph
● the driver must hold the steering wheel with both hands
● the change of trajectory is not accompanied by operation of theturn lights
● the Electronic Stability Control is activated and not in operation

and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant owner's
manual or in the general terms of
sale. These are also available online.
Customer information261Operating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, for example: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient and is
not stored for longer than an
operational cycle, and only processed on board the vehicle itself. Often
control units 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 technical equipment
levels, 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 where necessary. Staff working
for the service network ( 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 read 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.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.
