Driving
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
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.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
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.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
► ensure that the mat is secured correctly,
► never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.

Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.
The system detects signs on the left-hand side
and right-hand side, high and low, as well as
overlapping signs.
The system only detects circular signs.
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 operate correctly when
you change country, the units for speed in
the instrument panel must be those for 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.
It is possible for the system to not display the
speed limit if it does not detect a speed limit
sign within a preset period.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
When replacing the bulbs of the headlamps,
it is highly recommended that you fit genuine
replacement parts.
Using other bulbs could reduce system
performance.
Principles

Using the camera, located at the top of the
windscreen, this system detects and reads the
speed limit indications, overtaking prohibitions
and signs indicating the end of implementation of
the signs previously mentioned.
The sign is read by the camera and is displayed
in the instrument panel when it is passed (when
the vehicle is level with it).
Display on the touch
screen tablet then on the
instrument panel
The display of signs takes place as per the
following two phases:
– All new road signs recognised are displayed
on the touch screen tablet as a pop-up for 40
seconds.
– These signs are then displayed on the
instrument panel.
The system can display two road signs (speed
limit and no overtaking/end of no overtaking)

► Pull the control located on the side of the
dashboard towards you.
On the outside

► Push the lever located above the grille
upwards and lift the bonnet.
Do not open the bonnet under very windy
conditions.
When the engine is hot, handle the lever and
the stay with care (risk of burns).


► Unclip the stay and rotate it to insert it into
the first slot and then into the second slot.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water (rain,
washing, etc.) be limited.
Closing the bonnet

Practical information
A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .

the Identification markings of the
vehicle, and in particular the tyre pressure
label, refer to the corresponding section.
Changing a bulb
The headlamps have polycarbonate lenses with a protective coating:
► do not clean them using a dry or
abrasive cloth, nor with a detergent or
solvent product,
► use a sponge and soapy water or a pH
neutral product,
► when using a high pressure washer on
persistent marks, do not keep the lance
directed towards the lamps or their edges for
too long, so as not to damage their protective
coating and seals.
Changing a bulb must only be done with
the ignition off and after the lamp has
been switched off for several minutes - Risk
of serious burns!
► Do not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
with the same type and specification.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it
