continue to operate in a degraded mode.
This may be caused by a reduced visibility
(e.g. rain, fog, snow, blinding by low sun) or by a
real sensor blockage. In this case, stop the vehicle
and verify if the front camera or the front radar is
covered by dirt, snow, ice or anything preventing
the sensing.
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and an
audible signal.
Have it checked by a dealer or a qualified
workshop.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a dealer or a
qualified workshop to have the system checked.
These warning lamps light up on
the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's and/
or front passenger's seat belt is not fastened
(depending on version). The automatic braking
system is deactivated until the seat belts are
fastened.
Distraction detection
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.
The function comprises the "Driver Attention
Warning" and "Driver Attention Warning by
Camera" systems, combined, depending on
version, with the "DS DRIVER ATTENTION
MONITORING" system.
These systems are in no way designed to
keep the driver awake or to prevent the
driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated
at every engine start.
The settings are changed via the ADAS
touch screen application.
Driver Attention Warning
The system triggers an alert when it
detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70 km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the v
ehicle has been
stationary for more than 15 minutes.
–

The ignition has been s
witched off for a few
minutes.
–

The driv
er's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops
below 43 mph (70 km/h), the system goes
into standby.

Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a dealer or a qualified
workshop.
The system may be temporarily disturbed
by certain weather conditions (e.g. rain,
hail).
In particular, driving on a wet road or going
from a dry to a wet area can cause false alerts
(e.g. presence of a cloud of water droplets in
the blind spot interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in the
door mirrors, or the detection zones on the
front and rear bumpers with adhesive labels

138
Driving06
The sound emitted by the speaker (front
or rear) locates the obstacle relative to
the vehicle, whether in front of or behind it on
its path.
Side parking sensors

Using four additional sensors located on the sides
of the bumpers, the system records the position
of obstacles during the manoeuvre and indicates
them when they are located alongside the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were not
previously recorded will not be indicated.
Objects memorised during the manoeuvre
will no longer be stored after switching off
the ignition.
Deactivation/Activation
(Depending on country of sale)
It is configured in the ADAS touch screen
application.
If the function is deactivated, this
indicator lamp lights up on the instrument
panel.
The system status is saved when the ignition is
switched off.


The rear parking sensors are deactivated
automatically if a trailer or bicycle carrier
is connected to a towing device installed in
accordance with the Manufacturer's
recommendations.
In this case, the outline of a trailer is displayed
at the rear of the image of the vehicle.
When starting the vehicle, the graphic
and audible aids are only available after
the touch screen has started up.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when
changing into reverse gear, these
warning lamps light up on the instrument panel,
accompanied by the display of a message and an
audible signal (short beep).
Have it checked by a dealer or a qualified
workshop.
Reversing camera
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.
When reverse gear is engaged, with the engine
running, this system displays views of the
vehicle's close surroundings on the touch screen
using a camera located at the rear of the vehicle.




The screen is divided into 3 parts with a side
menu, a contextual view and a view from above
the vehicle in its close surroundings.

Vehicle data recording and privacy11
Vehicle data recording and
privacy
Electronic control units are installed in your
vehicle. These control units process data received
from the vehicle's sensors, for example, or data
they generate themselves or exchange with
each other. Some of these control units are
required for the correct operation of your vehicle,
some others assist you while driving (driving or
manoeuvring aids), while others provide comfort
or infotainment functions.
The following contains general information about
how data is processed within the vehicle.
You will find additional information about the
specific data which is downloaded, stored
and transmitted to third parties and what it
is used for in your vehicle under the keyword
"Data protection". This information is directly
associated with the references for the functions
in question contained in the corresponding
vehicle handbook, or in the general terms and
conditions of sale.
This information is also available online.
Vehicle operating data
The control units process the data used for the
operation of the vehicle.
This data includes, for example:
–
In
formation about the state of the vehicle
(e.g. speed, travel time, lateral acceleration,
wheel rotation rate, fastened seat belts display). –

En
vironmental conditions (e.g. temperature,
rain sensor, distance sensor).
As a general rule, this data is temporary, is
not stored for longer than one operating cycle
and is only used within the vehicle itself. The
control units often record this data (including
the vehicle's key). This function allows either the
temporary or permanent storage of information
about the state of the vehicle, stresses on
components, servicing requirements, as well as
events and technical errors.
Depending on the vehicle's equipment level, the
data stored is as follows:
–
O
perating state of system components
(e.g. filling level, tyre pressures, battery charge
status).
–
Faults and malfunctions in import
ant system
components (e.g. lamps, brakes).
–
Sy
stem reactions in specific driving situations
(e.g. deployment of an airbag, triggering of
stability control and braking systems).
–
In
formation about events which have damaged
the vehicle.
–
For electric and rechargeable h
ybrid vehicles,
the traction battery charge level and the
estimated driving range.
In particular circumstances (e.g. if the vehicle has
detected a malfunction), it may be necessary to
record data which would otherwise simply not be
stored.
When taking your vehicle in for servicing
(e.g. repairs, maintenance), the stored operating
data may be read along with the vehicle's identification number and used if necessary.
The personnel working for the servicing network
(e.g. garages, manufacturers) or third parties
(e.g. roadside assistance agents) may read the
vehicle's data. This also applies to work carried
out under warranty and quality assurance
measures.
This data is generally read via the OBD (On-Board
Diagnostics) port fitted by law to the vehicle. It
is used to report on the technical state of the
vehicle or its components and facilitates the
diagnosis of malfunctions, in compliance with
warranty obligations and for quality improvement.
This data, in particular the information relating
to stress on components, technical events,
operator errors and other malfunctions, is
sent to the Manufacturer, if necessary, along
with the vehicle's identification number. The
Manufacturer's liability may also be engaged. The
Manufacturer may also use the operating data
taken from the vehicle for product recalls. This
data may also be used to check the customer's
warranty and any claims made under warranty.
Any malfunctions stored in the vehicle may be
reset by an after-sales service company during
servicing or repair work, or at your request. Comfort and infotainment
functions
Comfort settings and personalised settings
may be saved in the vehicle and modified or
reinitialised at any time.
