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

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.

Load distribution
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle, and the nose weight approaches the
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
