of driving and manoeuvring aids .


This system warns the driver of a potential
danger posed by the presence of another vehicle
(car, lorry, motorcycle) in the vehicle's blind
spots (areas hidden from the driver's field of
vision) using sensors located on the sides of the
bumpers.


The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
–

immediately
, when being overtaken;
–

after a delay of about one second, when
overtaking a vehicle slowly

.
Activation/Deactivation
It is set via theDriving/Vehicle touch
screen menu.
When starting the vehicle, the
warning lamp
comes on in each mirror to indicate that the
system is activated.
The status of the system is memorised when the
ignition is switched off.

Driving

No alert is triggered in the following conditions:
– presence of stationary objects (e.g. parked
vehicles, safety rails, lampposts, signs).
–

vehicles travelling in the opposite direction.
–


on winding roads or in case of sharp turns.
–


when overtaking or being overtaken by a
very long vehicle (e.g.

truck, bus), which is both
detected in a blind spot from behind and present
in the driver's field of vision from the front.
–

quick overtaking manoeuvre.
–


very heavy traffic: vehicles detected in front
and behind are confused with a lorry or a
stationary object.
–


activation of
the Park Assist function.
Malfunction
If the event of a malfunction, this warning
lamp comes on in the instrument panel,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The system may be temporarily disturbed by certain climatic 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 or other objects; they may hamper
correct operation of the system.
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system:
–
warns the driver that their vehicle is at risk of
collision with the vehicle in front, a pedestrian or
,
depending on version, a cyclist.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
The speed will be reduced by a maximum of 12 mph (20 km/h) (versions
with camera only) or by a maximum of 31
mph (50
km/h) (versions with camera and
radar).
The system also takes motorcyclists into account.
This system is comprised of three functions:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance
(iEBA).
–


Active Safety Brake (automatic emergency
braking).

126
Driving
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 "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

lane markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

close to the vehicle ahead (lane markings
not detected);
–


roads that are narrow
, winding, etc.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This 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
within the sensors’ detection zone.
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 signalDepending on version, with
CITROËN Connect Nav, pressing
this button 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).

127
Driving
6When 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, in front or behind it.
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
The settings are changed via the Driving/Vehicle touch screen menu.
The system status is memorised when the
ignition is switched off.


The rear parking sensors system will be 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.
The parking sensors are deactivated while the
Park Assist function is measuring a space.
For more information on the Park
Assist
function, refer to the corresponding
section.
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, this warning
lamp lights 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.
Reversing camera

the view from above (zoom) as an obstacle is
approached during a manoeuvre.
Standard view

The area in front of your vehicle is displayed on
the screen.
The orange lines 1 represent the width of your
vehicle, with the mirrors unfolded; their direction
changes according to the position of the steering
wheel.
The red line 2 represents a distance of 30 cm
from the front bumper; the two orange lines 3
and 4 represent 1 m and 2 m, respectively.
This view is available with AUTO mode or in the
view selection menu.

132
Driving
Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the front of the vehicle in its
near surroundings, allowing the vehicle to be
manoeuvred around obstacles nearby.
This view is available with AUTO mode or in the
view selection menu.
Obstacles may appear further away than
they actually are.
It is important to check the sides of the
vehicle during the manoeuvre, using the
mirrors.
The parking sensors also supplement the
information on the vehicle's surroundings.
180° view

The 180° view assists with exiting from a parking
space in forward gear, making it possible to
see the approach of vehicles, pedestrians and
cyclists.
This view is not recommended for carrying out a
complete manoeuvre.
It consists of 3 areas: left A, centre B and right
C.
This view is available only from the view
selection menu.
Park Assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
This system provides active parking assistance:
it detects a parking space and then steers in the
appropriate direction to park in the space while
the driver controls the driving direction, gear
changes, acceleration and braking.
To help the driver monitor the manoeuvre, the
system automatically triggers the display from
the Top Rear Vision or 360 vision function and
activates the parking sensors.
The system measures the available parking
spaces and calculates the distances to obstacles
using ultrasonic sensors built into the front and
rear bumpers of the vehicle.


The system assists with the following
manoeuvres:
A. Entering a "parallel" parking space
B. Leaving a "parallel" parking space
C. Entering a "bay" parking space
