Safety
5In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.
Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could cause
injuries to the thorax or arm when the lateral
airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof, as they play a part in securing the
curtain airbags.
Child seats
The regulations on carrying children are specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations, all
children under the age of 12 or less than 4
ft 1

1” (150 cm) tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.

Safety
of the vehicle's rear seat, and is ideally in contact
with it.
Centre rear seat
A child seat with a support leg must never be
installed on the centre rear passenger seat .
Child seat at the front

► Adjust the front passenger seat to the
intermediate longitudinal position , with the
backrest straightened .
"Forward facing"

You must leave the front passenger
airbag active.
– Statistically , the safest seats in your
vehicle for carrying children are the rear
seats.
–

Children weighing less than 9 kg must
travel in the "rear facing" position, whether in
the front or rear of the vehicle.
It is recommended that children travel
on the rear seats of the vehicle:
–

‘rear facing’ up to the age of 3,
–

‘forward facing’ over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
Remove and stow the head restraint
before installing a child seat with
backrest on a passenger seat. Refit the head
restraint once the child seat has been
removed.
Advice
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
harness of child seats, keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly on the seat of the vehicle.
If the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
–

a child alone and unattended in a vehicle,
–


a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
–


the keys within reach of children inside the
vehicle.
Child seat at the rear
"Forward facing" or "Rearward
facing"




► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the "forward facing" child seat or the
"rearward facing" child seat itself do not touch
the vehicle's front seat.
►

V
erify that the backrest of the "forward facing"
child seat is as close as possible to the backrest

60
Safety

Driving
6certain 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.
On versions with camera alone, this message
indicates to you that the camera is obstructed:
"Driving aids camera: visibility limited, see
user guide".
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.
