ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Regulation
The driver must hold the steering wheel
properly.
When regulation is activated, the symbols are
displayed in green: with small steering inputs,
the system steers the vehicle and keeps it in the
position chosen by the driver in the traffic lane.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
At any time, the driver can change the position of
the vehicle by intervening on the steering wheel
and maintaining the position until the system has
taken it into account. If the chosen position is too
off-centre, an automatic re-centering manoeuvre
can occur. The system adjusts to the newly
defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
action on the brake pedal that causes the
Adaptive cruise control
system to be paused
will also cause the system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, the system must be
reactivated by pressing the button again.
Automatic suspension
Suspension of the system is accompanied by a
specific audible signal.

driving aids .
Deactivation is confirmed by the
illumination of this indicator lamp on the
instrument panel.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel, accompanied by the
display of a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Blind spot monitoring
For more information, refer to the
General recommendations on the use
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.


A warning lamp appears in the door mirror on the
side in question:
–

fixed
, immediately, when being overtaken.
–

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

, and when the
direction indicator is used.
Activation/Deactivation
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The settings are changed via the Driving
touch screen menu.
With MyCitroën Drive
The settings are changed via the Vehicle
touch screen menu.
With MyCitroën Drive Plus
The settings are changed via the ADAS
touch screen application.
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.
The system is automatically deactivated when towing with a towing device
approved by CITROËN.
Operating conditions
– All vehicles are moving in the same direction
and in adjacent lanes.
–

The speed of your vehicle must be between
7

and 87 mph (12 and 140 km/h) (versions
without Park Assist) or between 19
and 87 mph
(30
and 140 km/h) (versions with Park Assist).
–

When overtaking a vehicle, the speed
difference is less than 6

mph (10 km/h).

Driving
6It is possible that collision warnings are
not given, are given too late or seem
unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
If you select "Far" in the touch screen,
then the system warns sooner. This
increases the safety but increases also the
amount of alerts, if the legal safety distance is
not kept.
To reduce the alert occurrence, you can
change the setting to either of the other two.
Intelligent emergency
braking assistance (iEBA)
This function increases vehicle deceleration
if the driver does not brake enough to avoid a
collision.
This assistance is only provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of
impact or avoiding a collision if the driver fails to
react.
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).
Operation
The system operates in the following speed
ranges:
–

Between 3 mph and 50 mph (5
km/h and
80
km/h) when a stationary vehicle is detected.
–

Between 3 mph and 50 mph (5
km/h and
80
km/h) when a pedestrian is detected.
–

Between 3 mph and 50 mph (5
km/h and
80
km/h) when a cyclist is detected (versions
with camera and radar only).
–

Between 3 mph and 50 mph (5
km/h and
80
km/h) (versions with camera only) or 87 mph
(140
km/h) (versions with cameras 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.
With an automatic gearbox or drive selector, 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.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can override the automatic emergency braking at any time by
strongly turning the steering wheel (evasive
manoeuver) and/or by firmly pressing the
accelerator pedal.

137
Driving
6As 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
Depending on version, the Coffee Break Alert
system may be combined with the Driver
Attention Warning system.


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 at
risk: 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
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.
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.

Driving




The screen is divided into two parts with a
contextual view and a view from above the
vehicle in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
–
Standard view
.
–

180° view
.
–

Zoom view
.
AUTO mode is activated by default.
In this mode, the system chooses the best
view
to display (standard or zoom).
You can change the type of view at any time
during a manoeuvre.
►

Press the button in the bottom left-hand
corner of the touch screen.
►


Select the type of view:
•

"Standard view".
•
"180° view". •
"Zoom view".
• "AUTO view".
The display is immediately updated with the type
of view selected.
The system status is not saved when the ignition
is switched off.
Operating principle

Using one or two cameras, the close
surroundings of the vehicle are recorded whilst
manoeuvring at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
With 360 Vision, the image is created using
both cameras, when going forward and when
reversing.
When the function is activated, it is possible
that the view from above is not displayed. If the system is activated when the vehicle has
already moved, the view from above can be fully
displayed.

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.
An additional jet is fitted above the number plate to clean the reversing camera (depending on
version). ►

The washing of the reversing camera is
triggered by operating the rear screenwash.
Settings

To activate the camera, engage reverse gear.
The system is deactivated:
–
when changing out of reverse gear
.
–

by pressing the cross in the top left-hand
corner of the touch screen.
Automatic zoom view

The rear camera records the vehicle's
surroundings during the manoeuvre in order to
create a view from above the rear of the vehicle
in its close surroundings, allowing the vehicle to
be manoeuvred around nearby obstacles.
Using the sensors located on the rear bumper,
the automatic zoom view is displayed when
approaching an obstacle at the red line (less
than 30 cm) during the manoeuvre.
This view is only available automatically.
Obstacles may appear further away than
they actually are.
It is important to monitor the sides of the
vehicle during the manoeuvre, using the
mirrors.
Parking sensors also provide additional
information about the area around the vehicle.
Standard view

The area behind the vehicle is displayed on the
screen.
The blue 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 rear bumper; the two blue lines 3 and 4
represent 1
m and 2 m, respectively.
This view is available automatically or by
selection in the side menu.
