instrument panel, accompanied by the display of
a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
–
warns the driver that their vehicle is at risk of
collision with the vehicle in front, a pedestrian or
,
depending on version, a cyclist.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
The system also takes motorcyclists and animals into account; however, animals
below 0.5
m tall and objects on the road are
not necessarily detected.
This system is comprised of three functions:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not replace the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.

Driving
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or
when the "Near" trigger threshold has been
selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.
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.
ESC system in working order.
DSC/ASR systems activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with few bends.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
–

T
owing a trailer.
–

Carrying long objects on roof bars.
–


V
ehicle with snow chains fitted.
–

Before using an automatic car wash, with the
engine running.
–


Before placing the vehicle on a rolling road in
a workshop.
–


T
owed vehicle, engine running.
– Damaged front bumper (version with radar).
– Following an impact to 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.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
It is possible that 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.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front, or
with a pedestrian or cyclist present in their traffic
lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the Driving /
Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "Far", "Normal" or "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
steering wheel, etc.) to trigger the alert at the
most relevant moment.
Level 1 (orange): visual alert only,
warning that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
warning that a collision is imminent.
The message "Brake! " is displayed.
Where the speed of your vehicle is too
high approaching another vehicle, the

135
Driving
6first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or
when the "Near" trigger threshold has been
selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active 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 subject to 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 or a cyclist
is detected.
– The vehicle's speed is above 6 mph (10 km/h)
(versions with camera and radar) or between
6 mph and 53 mph (10
km/h and 85 km/h)
(versions with camera only) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With an automatic gearbox, in the event of
automatic emergency braking bringing the
vehicle to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
moving off again.
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 maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may 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
A fault in the system is signalled by the fixed illumination of this warning lamp,

137
Driving
6The 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.
Active Lane Departure Warning System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Using a camera located at the top of the
windscreen to identify lane markings on the road
and at the edges of the road (depending on
version), the system corrects the trajectory of the
vehicle while alerting the driver if it detects a risk
of unintentionally crossing a line or hard shoulder
(depending on version).
This system is particularly useful on motorways
and main roads.


Conditions for operation
– Vehicle speed between 43 and 112 mph (70
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
–


Direction indicators not activated.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or brakes.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the necessary trajectory
correction to return the vehicle to its initial path.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during trajectory correction.
The driver can prevent the correction by keeping a firm grip on the wheel (during
an avoiding manoeuvre, for example).
The correction is interrupted immediately if
the direction indicators are operated.


While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory is
intentional and no correction is triggered during
this period.
However, with the Blind Spot Monitoring system
activated, if the driver starts changing lanes and
another vehicle is detected in the vehicle's blind
spot, the system will correct the trajectory even
though the direction indicators are on.
For more information on the Blind Spot
Monitoring , refer to the corresponding section.
If the system detects that the driver is not
holding the wheel firmly enough during
an automatic correction of trajectory, it
interrupts the correction. An alert is triggered
to encourage the driver to take back control of
the vehicle.

6Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the front 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.
Obstacles may appear further away than
they actually are.
It is important to check the sides of the
vehicle during the manoeuvre, using the
mirrors.
The parking sensors also supplement the
information on the vehicle's surroundings.
180° view

The 180° view assists with exiting from a parking
space in forward gear, making it possible to
see the approach of vehicles, pedestrians and
cyclists.
This view is not recommended for carrying out a
complete manoeuvre.
It consists of 3 areas: left A, centre B and right
C.
This view is available only from the view
selection menu.
Park Assist
Refer to the General recommendations on the
use of driving and manoeuvring aids.
This system provides active parking assistance:
it detects a parking space then operates the
steering system to park in this space.
With
manual and automatic gearboxes, the
driver manages the accelerator, brakes and
forward and reverse gear engagement.
During phases of entry into and exit from a
parking space, the system provides visual and
audible information to the driver in order to make
the manoeuvres safe. Several forward and
reverse manoeuvres may be required.
At any time, the driver can take back control by
holding the steering wheel.


The Park Assist system provides assistance for
the following manoeuvres:
A. Entry into a "parallel" parking space
B. Exit from a "parallel" parking space
C. Entry into a "bay" parking space
The Park Assist system cannot operate
with the engine switched off.
When Park Assist is activated, it prevents
Stop & Start from going into STOP mode. In
STOP mode, activation of Park Assist restarts
the engine.

functions, such as the air conditioning and the
heated rear screen.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
The snow chains must be fitted only to the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Take account of the legislation specific to each country on the use of snow chains
and the maximum authorised speed.
Use only chains designed to be fitted to the type
of wheel fitted to the vehicle:
Original tyre size Maximum link size 215/65 R17 9 mm
225/55 R18 9 mm
235/55 R18 Cannot be fitted with
chains
205/55 R19 9 mm
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Installation tips
► To fit the chains during a journey, stop the
vehicle on a flat surface on the side of the road.
►

Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
►


Fit the chains following the instructions
provided by the manufacturer

.
►

Move off gently and drive for a few moments,
without exceeding 31

mph (50 km/h).
►

Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
