“ISOFIX" mountings
The seats shown below are fitted with ISOFIX
compliant mountings:


The mountings comprise three rings for each
seat, indicated by a marking:
– Two rings A, located between the vehicle seat
backrest and cushion.


The 2 latches of ISOFIX child seats are secured
to them.
– One ring B, located behind the seat, called
the TOP TETHER, for fixing seats fitted with an
upper strap.


This system prevents the child seat from tipping
forward in the event of a front impact.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.
To secure the child seat to the TOP TETHER:
► Remove and stow the head restraint before
installing the child seat on this seat (refit it once
the child seat has been removed).
► Pass the upper strap of the child seat behind the seat backrest, between the head restraint
rods.
► Secure the upper strap hook to ring B.► Tighten the upper strap.
When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering
with the operation of the seat belt.
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the installation
possibilities for ISOFIX child seats in
your vehicle, refer to the summary table.
Recommended ISOFIX child
seats
Also consult the user guide from the child seat’s manufacturer to find out how to
install and remove the seat.
Summary table of locations for ISOFIX child seats
In accordance with European regulations, this table shows the options for installing ISOFIX child seats on vehicle seats fitted with ISOFIX mountings.
In the case of universal and semi-universal ISOFIX child seats, the ISOFIX size category , determined by a letter from A to G, is indicated on the child seat

Driving
6the whole manoeuvre, in particular using the
mirrors.


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 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
in 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.
Head-up display
System which projects various information onto a
smoked blade in the driver's field of vision so that
they do not have to take their eyes off the road.

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).
