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 present in their traffic lane.
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 or on the head-up display.
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,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
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 "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
► Select one of the three pre-defined thresholds:– "Distant".– “Normal".– “Close".
The last threshold selected is memorised when
the ignition is switched off.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"COLLISION ALT" (Automatic emergency
braking).
► Then change the alert threshold.
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Auto. emergency braking".
► Then change the alert threshold.
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Collision
risk and auto. braking ".
► Then change the alert threshold.► Press "Confirm" to save the change.
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 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.

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".

11 2
Driving
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Fatigue
Detection System ".
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
Depending on version, the "Coffee Break Alert"
system is combined with the "Driver Attention
Warning" system.


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.
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.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.

Blind Spot Monitoring
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system includes sensors, placed on the
sides of the bumpers, and warns the driver of
the potentially dangerous presence of another
vehicle (car, truck, motorcycle) in the blind spot
areas of their vehicle (areas hidden from the driver's field of vision).

The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
– immediately, when being overtaken;– after a delay of about one second, when overtaking a vehicle slowly.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
When starting the vehicle, the warning lamp
comes on in each mirror to indicate that the
system is activated.
The state of the system stays in the memory
when switching off the ignition.
The system is automatically deactivated when towing with a towing device
approved by CITROËN.
Conditions for operation
– All vehicles are moving in the same direction and in adjacent lanes.– The speed of your vehicle must be between 7 and 87 mph (12 and 140 km/h).

11 4
Driving
– When overtaking a vehicle, the speed difference is less than 6 mph (10 km/h).– When overtaken by a vehicle, the speed difference is less than 16 mph (25 km/h).– Traffic is flowing normally.– Overtaking a vehicle over a certain period of time and the vehicle being overtaken remains in
the blind spot.
– You are driving on a straight or slightly curved road.– Your vehicle is not pulling a trailer, a caravan, etc.
Operating limits



No alert is triggered in the following conditions:– In the presence of non-moving objects (parked vehicles, barriers, street lamps, road signs, etc.).– Oncoming traffic.– Driving on a winding road or a sharp corner .– When overtaking or being overtaken by a very long vehicle (lorry, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
– When overtaking quickly.– In very heavy traffic: vehicles detected in front and behind are confused with a lorry or a
stationary object.
Malfunction
In the event of a malfunction, this warning lamp flashes for a few
moments in the instrument panel, accompanied
by the Service warning lamp coming on and the
display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on the
front and rear bumpers with adhesive labels
or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


Using sensors located in the bumper, this system signals the proximity of obstacles (e.g. pedestrian, vehicle, tree, barrier) present in their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
