6In certain extreme weather conditions
(rain and/or snow, bright sunshine, etc.)
the head-up display may not be legible or
may suffer temporary interference.
Some sunglasses may hamper reading of the
information.
To clean the blade, use a clean, soft cloth
(such as a spectacles cloth or microfibre
cloth). Do not use a dry or abrasive cloth
or detergent or solvent products as these
could scratch the blade or damage the anti-
reflection coating.
This system operates when the engine is running, and the settings are saved when
the ignition is switched off.
Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle) or
the cruise control (for a vehicle cruising speed).
You can memorise up to six speed settings for
each of the two systems.
By default, some speed settings are already
memorised.
As a safety measure, the driver must only modify the speed settings when
stationary.
Memorising speeds

This function can be accessed in the Driving / Vehicle menu of the touch
screen.
► Select the "Driving functions " tab.► Select the "Adjusting Speeds " function.

► Select the "Speed limiter" or "Cruise
control" tab corresponding to the equipment you
want to memorise new speed settings for.
► Select the speed setting you want to change.► Enter the new value using the numeric keyboard and confirm.
► By default, some speed settings are already memorised.
“MEM” button

With this button, you can select a memorised
speed setting to use with the speed limiter or the
programmable cruise control.
For more information on the Speed limiter or
Cruise control, refer to the associated section.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .

102
Driving
This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.– Speed limit details from the navigation system mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to work correctly when
changing country, the speed unit in the
instrument panel must correspond to that of
the country you are driving in.
The automatic reading of road signs is a driving aid system and does not always
display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit in the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).

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.

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).

Driving
6Using 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.
Visual assistance


This supplements the audible signal 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
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h).
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if no further obstacles are detected
or when the speed of the vehicle exceeds 6 mph
(10 km/h).
The sound emitted by the speaker (front or rear) indicates whether the obstacle is
in front or behind.

Top Rear Vision
Refer to the General recommendations on the
use of driving and manoeuvring aids .


As soon as reverse gear is engaged with the
engine running, this system displays views of
your vehicle’s close surroundings on the touch screen using a camera located at the rear of the
vehicle.



The screen is divided into two parts with a
contextual view and a view from above the
vehicle in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
– Standard view
.
– 180° view.– Zoom view .AUTO mode is activated by default.
In this mode, the system chooses to display the
best view (standard or zoom).
You can change the type of view at any time
during a manoeuvre.
The state of the function is not saved when the
ignition is switched off.
Principle of operation

Using the rear camera, the vehicle's close
surroundings are recorded during manoeuvres
at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
Rear vision

To activate the camera, located on the tailgate,
engage reverse and keep the speed of the
vehicle below 6 mph (10 km/h).The system is deactivated:– Automatically, at speeds above approximately 6 mph (10 km/h),– Automatically, if the tailgate is opened.– Upon changing out of reverse gear (the image remains displayed for 7 seconds).– By pressing the white arrow in the upper-left corner of the touch screen.
