6Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
Vehicle moving forward without trailer.
Brake system operational.
ASR / ESP system activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the instrument panel without any additional
message, to indicate that the “automatic braking
system” is not available. This is a normal
behavior indicating that a condition is not fulfilled
and which does not request the support of a
workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the
system via ADAS touch screen application is
recommended, for instance:
–

T

owing a trailer (particularly a trailer without its
own braking system).
–

Carrying long objects on roof bars.
–


Driving with snow chains.
– Using an automatic car wash.
– Performing any maintenance (e.g. changing a
wheel, working underhood).
–

Placing the vehicle on a rolling bench in a
workshop.
–


T
owing the vehicle.
–

Following a front bumper deformation (version
with radar).
–


Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated if:
–

A

spare wheel with a too small diameter is
detected.
–

A

fault with the brake pedal switch or with
the right or left brake lamp is detected.
–

A

fault in the sensors, in the electronic or in
the brake system is detected.
–

A

trailer is detected by the equipped vehicle
hitch (with an electrical connection plug).
The system diagnoses permanently its capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions.
Examples: sensor initialization, board voltage
out of regular range, activation of stability
system…
Therefore the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not load his vehicle excessively (respect of MTAC values,
MTRA values and loading height on roof
bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►

Select one of the 3 preset thresholds: “ Far

”,
“Medium” or “Near”.
The selected threshold is memorised when the
ignition is switched off.

6Operation
The system operates subject to the following
conditions:
–
The vehicle's speed does not exceed 50
mph (80 km/h) when a pedestrian or a cyclist is
detected.
–


The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
–


The vehicle's speed is between 6 mph and
53 mph (10

km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes. During
the flashing time, the function is not available.
In the event of automatic emergency braking,
keep the brake pedal depressed, also after a
complete stop is reached, to prevent the vehicle
from rolling away.
The driver can override the "automatic emergency braking" at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.
The brake pedal may feel hard and vibrate slightly while the function is
operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Turning scenarios
Crossing road with another vehicle

The system may operate when the vehicle is
turning and detects another vehicle, on the
adjacent lane, approaching from the opposite
direction if:
–

The corresponding direction indicator is
activated.
–


Then the vehicle is about to cross the path of
another vehicle.
–


The vehicle speed is between 3 and 12
mph
(5 and 20
km/h).
–

A
collision on the side of the other vehicle is
probable.
Crossing road with a pedestrian

The system may operate when the vehicle
is turning left or right and detects a crossing
pedestrian if:
–

The pedestrian is crossing in front of the
vehicle.
–


The pedestrian can clearly be detected by the
sensors.
–


The scenery is detectable by the sensors (e.g.
brightness, contrast vs background).
–


The vehicle speed is between 3 and 15
mph
(5 and 25
km/h).
Malfunction
This warning lamp lights up on the instrument panel with the message
"Sensor blind" in certain cases. With the variant
"camera only", the system is deactivated. With
the variant "camera and radar", the system may
continue to operate in a degraded mode. This
may be caused by a reduced visibility (rain, fog,
snow, blending by low sun…) or by a real sensor
blockage. In this case, stop the vehicle and verify

(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 "Coffee Break Alert"
system combined with the "Driver Attention
Warning" 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.
It is configured in the ADAS touch screen
application.
Coffee Break Alert
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 vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver'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.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).
Driver Attention Warning

The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by
the message "Caution!“, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Driving

monitoring
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system warns the driver of vehicles
approaching rapidly from the rear in adjacent
lanes (up to around 75 m) and of the presence of
a vehicle in the blind spots of their vehicle, using
corner radars located in the rear bumper.
This system takes into account vehicles
such as cars, lorries and motorcycles by
monitoring the blind spots or areas hidden
from the driver's field of vision.

133
Driving
6This system detects and signals the proximity of
obstacles (e.g. pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalPressing this button in the touch
screen opens the window for
adjusting the volume of the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10
km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6
mph (10 km/h).
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.
Deactivation/Activation
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.

134
Driving
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 CITROËN dealer or a
qualified workshop.
Top Rear Vision
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.
The parking sensors supplement the information
in the view from above the vehicle.
Different contextual views are available:
–
Automatic zoom view
.
–

Standard view
.
–

Panoramic view
.
Depending on the context, the system chooses
the best view to display (standard or automatic
zoom).
The view type can be changed at any time
during the manoeuvre.
The system status is not saved when the ignition
is switched off.
Operating principle

Using the camera, the vehicle's close
surroundings are recorded during low speed
manoeuvres.
An image from above the vehicle in its close
surroundings is created in real time (on the side
of the screen), as the vehicle progresses.
This view makes it easier to align the vehicle
when parking and to perceive nearby obstacles.
It is automatically deleted if the vehicle remains
stationary for too long.
Configuration
In the side menu, this menu allows you to
carry out the following operations:
–

volume adjustment of the audible signal.
–


brightness adjustment.
–


contrast adjustment.
–

functions (depending on version).
The symbol is complemented by an audible
signal when the vehicle is reversing.
An obstacle is approaching in the blind spot on the rear right-hand/
left-hand side or on both sides of the vehicle.
In the event of a malfunction of these visual
display functions or of the touch screen, or if the
driver deactivates the views from these functions
on the touch screen, detection of an approaching
obstacle is still indicated by the audible signal
when the vehicle is reversing.

Extreme temperature changes.
–


Damaged rear bumper
.
–

Accumulation or projection of external
elements (e.g. mud, frost, snow), stickers
application.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of your
vehicle and be prepared to react at any time
to avoid an accident.
In the event of repainting the rear
bumper, consult the CITROËN dealer or
a qualified workshop; certain types of paint
could interfere with the operation of the
radars.
