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.
–


activation/deactivation of camera washing
(depending on version).
Activation/Deactivation
To activate the camera, engage reverse gear.

Driving
Operating principle



When an approaching obstacle is detected, the
symbol 1 or 2 flashes on the touch screen, in the
Parking sensors view or in the various contextual
views of the Top Rear Vision or 360 vision
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.
Activation/Deactivation
It is configured in the ADAS touch screen
application.
The system's status is saved when the ignition is
switched off.
Operating limits
The system may not work in the following cases:
– T owing a trailer.
–

Using a bicycle carrier on a towing device.
–


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.
Malfunction
In the event of a malfunction when
engaging reverse gear, during reversing
or when the driver attempts to activate the system, this warning lamp lights up on the
instrument panel, accompanied by the display of
a message and an audible signal.

maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance.
The maximum towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and their
wiring harnesses approved by CITROËN.
We recommend having them fitted by a
CITROËN dealer or a qualified workshop.
If not fitted by a CITROËN dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Important: with a motorised tailgate and its
Hands-Free Tailgate Access function, if a
towing device is fitted outside the CITROËN
dealer network, it is essential to visit a
CITROËN dealer or a qualified workshop
to recalibrate the detection system. Risk
