Access
Ensure that any luggage or accessories
carried on the roof bars do not interfere
with the movement of the sunroof.
Do not place heavy loads on the movable
glass panel of the sunroof.
If the sunroof is wet, following a shower
or washing the vehicle, wait until it is
completely dry before opening.
Do not operate the sunroof if it is covered by
snow or ice - risk of damage!
Use only plastic scrapers to remove snow or
ice from the sunroof.
Regularly check the condition of the
sunroof seals (e.g. presence of dust,
dead leaves).
If using a car wash, check first that the roof is
correctly closed and keep the high-pressure
jet at least 30 centimetres from the seals.
Never leave the vehicle with the sunroof
open.
Operation
When opening the sunroof fully, the movable
glass moves to a partially open position, then
slides over the roof. Any intermediate position is
possible.
Before operating the sunroof control
button, ensure that no object or person
might prevent the movement.
Pay particular attention to children when
operating the sunroof.
If something is trapped when operating the
sunroof, reverse the movement of the sunroof
by pressing the control button in question.
The driver must ensure that passengers use
the sunroof correctly.
Any manual intervention on the position of
the sunroof may disturb the anti-pinch device.
Perform a reinitialisation.
Anti-pinch system
If the sunroof encounters an obstacle when
closing, the movement is automatically reversed.
Opening/closing the sunroof
► To open the sunroof, use the part of the
button located towards the rear.

Pressing the button again stops the
movement in progress.
►


By keeping the button pressed (without going
beyond the point of resistance), the movement of
the glass stops when this button is released.
► When the sunroof is closed: pressing once
without passing the point of resistance moves it
to the partially open position.
►

When the sunroof is partially open: pressing
once on the front part of the button, without
going beyond the point of resistance, closes it
completely

.
The sunroof and windows can be closed by holding down the remote control
locking button.

battery, or if the sunroof malfunctions or moves
in a jerky manner.
►

Check that nothing is affecting the movement
of the sunroof and that the seals are clean.
► With the ignition on, press and hold
the front part of the button to close the
sunroof.
The sunroof closes step by step. When fully
closed, it performs a slight opening/closing
movement.

Automatic lighting systems - General
recommendations
The automatic lighting systems use a detection
camera, located at the top of the windscreen.
Operating limits
The system may be disrupted or not work
correctly:
–

When visibility conditions are poor
(e.g.

snowfall, heavy rain).
–

If the windscreen is dirty
, misted-up or
masked (e.g.
sticker) in front of the camera.
–

If the vehicle is facing highly reflective signs
or safety barrier reflectors.
The system is not able to detect:
–


Road users that do not have their own
lighting, such as pedestrians.
–


V

ehicles with hidden lighting (e.g. travelling
behind a safety barrier on the motorway).
–

V

ehicles at the top or bottom of a steep
slope, on winding roads, on crossroads.
Maintenance
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.

– When a vehicle cuts in sharply between your
vehicle and the one in front.
Some vehicles on the road may be
poorly perceived or interpreted by the
camera and/or the radar (e.g.
truck), which
can lead to an incorrect evaluation of
distances and result in inappropriate
acceleration or braking of the vehicle.
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:
–

Following an impact on the windscreen
close to the camera or on the front bumper
(versions with radar).
–


Brake lamps not working.
If the vehicle has undergone any of the
following modifications, do not use the
system:
–

Carrying long objects on roof bars.
–


Towing.
–

Use of the "space-saver" type spare wheel
(depending on version).
–


Front end of the vehicle modified (for
example by adding long-range headlamps or
painting the front bumper).
–


Obstructed radar and/or camera.
Malfunction
In the event of a malfunction,
dashes are displayed instead of
the speed setting.
This warning lamp comes on, accompanied by a message and an
audible signal, to confirm the malfunction.
Have it checked by a CITROËN dealer or a
qualified workshop.
Lane positioning assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


The system identifies the edges of the traffic lane
and steers the vehicle to keep it inside this lane
and maintain the lateral position chosen by the
driver.
To do this, the system uses a camera placed on
the upper part of the windscreen.
This system is particularly suited to driving on
motorways and main roads.
Activation/Deactivation
The Lane positioning assist system is
automatically activated, after selecting Highway
Driver Assist mode.
For more information on the Highway Driver
Assist system, refer to the corresponding
section.
The selection is confirmed by the display of
the symbols on the instrument panel or on the
head-up display (if fitted), representing the
steering wheel and the side lines.
The colour of the symbols depends on the
operating state of the system:
(grey)
One or more operating conditions is not
met; the system is paused.
(green)

134
Driving
– Towing a trailer (particularly a trailer without its
own braking system).
–
Carrying long objects on roof bars.
–


Driving with snow chains.
–


Using an automatic car wash.
–


Performing any maintenance (e.g.
changing a
wheel, working inside the engine compartment).
–

Placing the vehicle on a rolling bench in a
workshop.
–


T
owing the vehicle.
–

Following a damage of 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.
Following a severe crash (e.g.
with airbag
deployment), the system is automatically
deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
In case the detection is degraded or
temporarily unavailable by environment
conditions, then a driver indication is not
displayed (because a driver action is not
requested).
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle (keep within the GVW limit and load
height limits for roof bars).
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The selected threshold is memorised when the
ignition is switched off.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The threshold is set via the Driving touch screen menu.
►

Select one of the three pre-defined
thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive
The threshold is set via the Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive Plus
The threshold is set via the ADAS touch screen application.
► Select one of the 3 preset thresholds: " Far ",
"Medium" or "Near".
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the
collision risk, and the operation of the vehicle
(e.g.
actions on the pedals, steering wheel) to
trigger the alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given,
confirming the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed
directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically
at lower speed.

138
Driving
Adjusting the audible signal
(With MyCitroën Drive or MyCitroën
Drive Plus)
Pressing this button opens the window
for adjusting the volume of the audible
signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, 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
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10
km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, in front or behind it.
Side parking sensors

Using four additional sensors located on the
sides of the bumpers, the system records the
position of obstacles during the manoeuvre and
indicates them when they are located alongside
the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were
not previously recorded will not be indicated.
Objects memorised during the
manoeuvre will no longer be stored after
switching off the ignition.
Deactivation/Activation
(Depending on country of sale)
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The settings are changed via the Driving
touch screen menu.
With MyCitroën Drive
The settings are changed via the Vehicle
touch screen menu.
With MyCitroën Drive Plus
The settings are changed via the ADAS
touch screen application.

Roof bars
As a safety measure and to avoid damaging the roof, it is essential to use
transverse roof bars approved for your
vehicle.
Observe the instructions on fitting and use
contained in the guide supplied with the roof
bars.
Maximum load distributed over the
transverse roof bars, for a loading height
not exceeding 40 cm (except bicycle carrier):
80

kg.
As this value may change, please verify the
maximum load quoted in the guide supplied
with the roof bars.
If the height exceeds 40 cm, adapt the speed
of the vehicle to the profile of the road to
avoid damaging the roof bars and the fixings
on the vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects that are longer than the vehicle.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one of the sides.
Arrange the heaviest part of the load as close
as possible to the roof.
Secure the load firmly.
