speed setting on the instrument panel.
Temporarily exceeding the
speed setting
► Press the accelerator pedal down fully .The speed limiter is deactivated temporarily and
the displayed speed setting flashes.
► Release the accelerator pedal to return to below the programmed speed.
When the limit speed is exceeded but this is not
due to action by the driver (in case of a steep
slope, for example), an audible signal triggers
immediately.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
Brake if necessary to control the speed of
your vehicle.
Once the speed of the vehicle returns to the
programmed setting, the speed limiter functions
again: the display of the speed setting becomes
fixed again.
Switching off
► Turn the thumbwheel 1 to the "OFF" position:
the display of information on the speed limiter
disappears.
Malfunction

The display of dashes (flashing then fixed)
indicates a fault with the speed limiter.
Have it checked by a CITROËN dealer or a
qualified workshop.
Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of pedestrians crossing the road.– In heavy traffic.– On winding or steep roads.– On slippery or flooded roads.– In poor weather conditions.– Driving on a speed circuit.– Driving on a rolling road.– When using snow chains, non-slip covers or studded tyres.
Cruise control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically keeps the vehicle’s speed at the cruise value
programmed by the driver (speed setting), without using the accelerator pedal.
The cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40 km/h).With a manual gearbox, third gear or higher must
be engaged.
With an automatic gearbox, mode D or second gear or higher in mode M must be engaged.
The cruise control remains active after changing gear, regardless of the gearbox
type, on engines fitted with Stop & Start.

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.

► 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".

120
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).
