Driving
– Towing 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.
–

owing the vehicle.
–

Following a damage of the windscreen close
to the detection camera.
The system is automatically deactivated when the use of certain types of
"space-saver" spare wheel (smaller diameter)
is detected, or if a fault with the brake pedal
switch or at least two brake lamps is detected.
Following a severe crash (e.g.
with airbag
deployment), the system is automatically
deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
In case the detection is degraded or
temporarily unavailable by environment
conditions, then a driver indication is not
displayed (because a driver action is not
requested).
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle (keep within the GVW limit and load
height limits for roof bars).
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.
The selected threshold is memorised when the
ignition is switched off.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The threshold is set via the Driving touch screen menu.
►

Select one of the three pre-defined
thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive
The threshold is set via the Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive Plus
The threshold is set via the ADAS touch screen application.
► Select one of the 3 preset thresholds: " Far ",
"Medium" or "Near".
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the
collision risk, and the operation of the vehicle
(e.g.
actions on the pedals, steering wheel) to
trigger the alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given,
confirming the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed
directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically
at lower speed.

136
Driving
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.
Malfunction
This warning lamp lights up on the instrument panel, if the automatic braking
system is reduced or degraded.
This is a normal behavior, which does not
request the support of a qualified workshop.
This may be caused by a reduced visibility
(e.g.

rain, fog, snow, blinding by low sun) or by
a real sensor blockage. In this case, stop the
vehicle and verify if the front camera or the front
radar is covered by dirt, snow, ice or anything
preventing the sensing.
In the event of a malfunction, this warning
lamp lights 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.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
These warning lamps light up on the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's
and/or front passenger's seat belt is not fastened
(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 .
Depending on version, the function consists of
either the "Coffee Break Alert" system alone or
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.
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.
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.

138
Driving
Adjusting the audible signal
(With MyCitroën Drive or MyCitroën
Drive Plus)
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).
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, 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
(Depending on country of sale)
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.
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.


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.
