6When moving off again, watch out for
cyclists, pedestrians and animals, as
they may not be detected properly.
Operating limits
Cruise control operates by day and night, in fog
or moderate rainfall.
Certain situations cannot be managed by the
system and require driver intervention.
Cases of non-detection by the system:
–

Pedestrians, some cyclists, animals.
–


Stationary vehicles (traffic jam, breakdown,
etc.).


– Vehicles crossing your lane.
– V ehicles driving in the opposite direction.
Situations in which the driver must pause the
cruise control system:


– Vehicles in a tight bend.
– When approaching a roundabout.

– When following a narrow vehicle.
Reactivate cruise control when conditions permit.
Situations in which the driver is prompted to
immediately resume control:
–

Excessively sharp deceleration by the vehicle
in front of you.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Pay particular attention:
– When motorcycles are present and
when there are vehicles staggered across the
traffic lane.
–

When entering a tunnel or crossing a
bridge.
If any of the following malfunctions
occurs, do not use the system:

Active Lane Keeping
Assist
Refer to the General recommendations on the
use of driving and manoeuvring aids .


Using a camera located at the top of the
windscreen, the system identifies lane markings
and steers the vehicle inside this lane to keep it
in the lateral position chosen by the driver.
This function is primarily suitable for driving on
motorways and main roads.
Operating conditions
– Adaptive Cruise Control active.
– T raffic lane marked out by lines on both sides.
–

ESC system operational.
–


ASR/CDS systems activated.
–


No trailer detected.
–


No 'space-saver' spare wheel in use.
–


V
ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Activation/Deactivation



► With the Adaptive Cruise Control with Stop &
Go function activated, press this button.
The action is confirmed by:
–

The indicator lamp in the button lighting up
green.
–


The following symbol being displayed on the
instrument panel.
The colour of the symbol on the instrument panel
depends on the operating status of the system:
(grey colour)
One or more operating conditions is not
met; the system is paused.
(green colour)
All operating conditions are met; the
system is active.
(orange colour)
System malfunction.
If the driver no longer wishes to use the system
for a while, they can deactivate it by pressing the
button again.
The indicator lamp in the button goes off and the
symbol disappears from the instrument panel.
The system status is saved when the ignition is switched off.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbol is
displayed in green: by small steering actions,
the system directs the vehicle and keeps it in the
position chosen by the driver, in the traffic lane.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
The driver can change the position of the vehicle
at any time, by turning the steering wheel, which
suspends the function. The driver positions the
vehicle where they wish to in the lane. When
the driver feels that the vehicle’s position is
appropriate, they maintain it until the function
is reactivated. The system regains control by
regulating on the new defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
action on the brake pedal that results in cruise

131
Driving
6control being paused will also cause the
system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, you must reactivate it by
pressing the button again.
Automatic pause
– Triggering of the ESC.
– Prolonged failure to detect one of the lane limit
markings. In this case, the
Active lane departure
warning function can take over, and the system
will reactivate itself once the operating conditions
are met again.
In response to action by the driver:
suspension
– Activation of the direction indicators.
– T ravelling outside the lane limits.
–

T
oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–


Pausing of the cruise control.
–


Deactivation of the DSC/ASR systems.

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.

134
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,

136
Driving
The 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.


accompanied by the display of a message and
an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
These warning lamps come on if the driver's seat belt and/or front
passenger seat belt (depending on version) are
not fastened.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break if you are feeling tired or at least
every 2 hours.
The function consists of the "Coffee Break Alert"
system 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
This function is set via the touch screen Driving/Vehicle menu.
The state of the system is memorised when the
ignition is switched off.
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65
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.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65
km/h).
Driver Attention Warning

Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65
km/h)).
At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
