6Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 37 mph (60 km/h) when a pedestrian is detected.
– The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 6 mph and 53 mph (10 km/h and 85 km/h) when a moving vehicle is detected.This warning lamp flashes (for approximately 10 seconds) as soon as
the function acts on the vehicle’s braking.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or sharply pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a fault with the system, you are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break in case of feeling tired or at least
every 2 hours.
Depending on version, the function consists of
just the "Coffee Break Alert" system, or of this
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.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"VIGILANCE ALT " (Fatigue Detection System).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Fatigue Detection System".

approached at the level of the red line (less than
30 cm) during a manoeuvre.
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 depending on 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 with AUTO mode or in the
view selection menu.
Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the rear 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.

You can deactivate the function at any time until the parking space entry or exit
manoeuvre begins, by pressing the arrow
located in the top left-hand corner of the
display page.
Selecting the type of manoeuvre

A manoeuvre selection page is displayed on the
touch screen: by default, the "Entry" page if the
vehicle has been running since the ignition was
switched on, otherwise, the "Exit" page.
► Select the type and side of the manoeuvre to activate the parking space search.
The selected manoeuvre can be changed at
any time, even while searching for an available
space.
Parking space search
► You should drive at a distance of between 0.50 m and 1.50 m from the row of parked vehicles, without ever exceeding 19 mph (30 km/h), until the system finds an available space.
The parking space search is suspended at
higher speeds. The function is automatically
deactivated if the vehicle speed exceeds 31 mph
(50 km/h).
For "parallel" parking, the space must
measure at least the length of your
vehicle plus 0.60 m.
For "bay" parking, the space must be at least
as wide as your vehicle plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle touch
screen menu, it will be automatically
reactivated when the system is activated.


When the system finds an available space, " OK"
is displayed on the parking view, accompanied
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle“,
accompanied by the “ STOP” sign and an audible
signal.
Once the vehicle has stopped, an instructions
page is displayed on the screen.
► To prepare for the manoeuvre, follow the instructions.
The start of the manoeuvre is indicated by the
"Manoeuvre under way" onscreen message
and an accompanying audible signal.
Reversing is indicated by this message:
“Release the steering wheel, reverse ”.
The Top Rear Vision and the parking sensors
are automatically activated to help you monitor
the area immediately surrounding your vehicle
during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering. It gives instructions on the manoeuvring direction
when starting "parallel" entry and exit parking
manoeuvres, and for all "bay" entry manoeuvres.
These instructions are displayed as a symbol
accompanied by a message:
"Reverse".

Driving
“Go forwards".
The manoeuvring status is indicated by these
symbols:
Manoeuvre in progress (green).
Manoeuvre cancelled or finished (red) (the arrows indicate that the driver must
resume control of the vehicle).
The maximum speeds during manoeuvres are
indicated by these symbols:
75 mph or 7 km/h, for parking space entry.
53 mph or 5 km/h, for parking space exit.
During manoeuvring phases, the steering
wheel performs rapid turns: do not hold
the steering wheel or put your hands between
the spokes of the steering wheel. Watch out
for any objects that could interfere with the
manoeuvre (loose clothing, scarf, tie, etc.).
Risk of injury!
It is the driver's responsibility to constantly
monitor the traffic, especially vehicles coming
towards you.
The driver should check that no objects or
people are obstructing the vehicle’s path.
The images from the camera(s) displayed on the touch screen may be
distorted by the terrain.
In shady areas, or in inadequate sunlight
or lighting conditions, the image may be
darkened and with lower contrast.
The manoeuvre can be permanently interrupted
at any time, either by the driver or automatically
by the system.
Interruption by the driver:
– taking over control of the steering.– activating the direction indicator lamps on the opposite side to that of the manoeuvre.– unfastening the driver's seat belt.– switching off the ignition.Interruption by the system:– vehicle exceeding the speed limit of 5 mph (7 km/h) during parking space entry manoeuvres, or 3 mph (5 km/h) during parking space exit manoeuvres.– activation of anti-slip regulation on a slippery road.
– opening of a door or the boot.– engine stall.– system malfunction.– after 10 manoeuvres to enter or exit a parallel parking space and after 7 manoeuvres to enter a
parking bay.
Interrupting the manoeuvre automatically
deactivates the function. The manoeuvre symbol is displayed in red,
accompanied by the "
Manoeuvre cancelled"
message on the touch screen.
A message prompts the driver to take back
control of the vehicle.
End of the parking space entry or exit
manoeuvre
The vehicle stops as soon as the manoeuvre is
completed.
The manoeuvre symbol is displayed in red,
accompanied by the message “ Manoeuvre
completed” on the touch screen.
When entering a parking space, the driver may
be required to complete the manoeuvre.
Operating limits
– The system may suggest an unsuitable parking space (No Parking area, work in
progress with damaged road surface, location
alongside a ditch, etc.).
– The system may indicate that a space has been found but not offer it because of a fixed
obstacle on the opposite side of the manoeuvre,
which would not allow the vehicle to follow the
necessary trajectory for parking.
– The system may indicate that a space has been found but not engage the manoeuvre
because the road is too narrow.
– The system is not designed to perform the parking manoeuvre on a sharp bend.– The system does not detect spaces that are much larger than the vehicle or are bounded by
obstacles that are very low (pavements, studs, etc.) or very thin (trees, posts, wire fences, etc.).– Certain obstacles located in the sensors’ blind spots may not be detected or may no longer be
detected during the manoeuvre.
– Certain materials (fabrics) absorb sound waves: pedestrians may not be detected.– A front or rear impact to the vehicle can upset the sensors’ settings, which is not always
detected by the system: distance measurements
may be distorted.
– If the boot is heavily loaded, the vehicle may tilt, affecting distance measurements.
The vehicle's sensors and camera(s) may be
impaired by:
– accumulated snow or fallen leaves on the road,– adverse weather conditions (heavy rain, thick fog, falling snow),– noise interference from noisy vehicles and machinery (lorries, pneumatic drills, etc.).
Do not use the function under the
following exterior conditions:
– Alongside a soft shoulder (e.g. ditch) or quay or on the edge of a drop.– When the road surface is slippery (e.g. ice).
If any of the following malfunctions
occurs, do not use the system:
– If a tyre is under-inflated.– If one of the bumpers is damaged.– If one of the cameras is faulty.
