Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Fasten your seat belt, ensuring it is
positioned correctly.
Do not leave anything between the
occupants and the airbags (a child, pet,
object, etc.), nor fix or attach anything close
to the inflation trajectory of the airbags;
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 or broken into, have the airbag
systems checked.
All work on the airbag systems must be
carried out by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are obser ved, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. 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 fit or attach anything to the steering
wheel or dashboard, this could cause injuries
with deployment of the airbags.
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.
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 attach anything to or hang anything
from the seat backrests (clothes, etc.) as this
could cause injuries to the thorax or arm if 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. Curtain airbags
Do not attach anything or hang anything to
the roof, as this could cause head injuries
when the curtain airbag is deployed.
If fitted to your vehicle, do not remove the
grab handles installed on the roof, they play a
part in securing the curtain airbags.
Safety

Blind spot monitoring
This system warns the driver of the presence of
another vehicle in the blind spot angle of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a vehicle slowly. This driving aid system is designed to
improve safety when driving and is in no
circumstances a substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
distances and relative speeds of other
vehicles and to predict their movements
before deciding whether to change lane.
This system is a driving aid that cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
Activation and deactivation of the system is
done in the vehicle configuration menu.
F

I
n the Driving/Vehicle menu
of the touch screen, select the
" Vehicle settings " tab then
" Safety " and activate/deactivate
" Blind spot sensors ".
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The status of the system remains in memory
when the ignition is switched off. The system is automatically deactivated
when towing with a towing device
approved by CITROËN.
Operation
The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle – car, lorry,
bicycle – is detected.
The following conditions must be met for this:
-

a
ll vehicles are moving in the same direction
and in adjacent lanes,
-

t
he speed of your vehicle must be between
7 and 87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
-

a v
ehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
-

t
raffic is flowing normally,
-

w
hen overtaking a vehicle over a certain
period of time and the vehicle being
overtaken remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer, a
caravan, etc.

Driving

124
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
No alert will be given in the following situations:
-

i

n the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
-
on

coming traffic,
-

d

riving on a winding road or a sharp corner,
-
w
hen overtaking or being overtaken by a
very long vehicle (lorry, bus, etc.) that is
detected in the rear blind spot but is also
present in the driver's front field of vision,
-
w
hen overtaking quickly,
-
i
n very heavy traffic: vehicles detected in
front and behind are confused with a lorry or
a stationary object.
Operating fault
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad weather or in winter, ensure that
the sensors are not covered with mud, ice
or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
the correct operation of the system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.
In the event of a malfunction, you are warned
by the display of a message.

125
Parking sensors
This function is a manoeuvring aid which
cannot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain attentive and stay
in control of their vehicle.
They must always check the vehicle's
surroundings before undertaking a
manoeuvre.
During the entire manoeuvre, the driver
must ensure that the space remains clear.
Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistance
The function signals the presence of obstacles
both within the sensor detection zone and in
the vehicle path defined by the orientation of
the steering wheel.
In the example shown, only the obstacles
present in the shaded area will be signalled by
the audible assistance.The information on proximity is given by an
intermittent sound signal, the frequency of which
becomes more rapid as the vehicle approaches
the obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the sound signal becomes
continuous.
The sound emitted by the speaker (right or left)
allows you to identify which side the obstacle is on.
Adjusting the audible signal
Visual assistance
Using sensors located in the bumper, this
function warns of the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) entering
their field of detection. On versions equipped with
CITROËN Connect Radio,
pressing this button opens
the audible signal volume
adjustment window.

Driving

126
It supplements the audible assistance,
regardless of the vehicle's path, by displaying
on the screen those whose location represents
the distance between the obstacle and the
vehicle (white: more distant obstacles, orange:
close obstacles, red: very close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).The sound emitted by the speaker (front or
rear) locates the obstacle in relation to the
vehicle – in the vehicle trajectory, in front
or behind.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu. F

I
n the Driving/Vehicle
menu
of the touch screen, select the
" Driving functions " tab, then
deactivate/activate " Parking
sensors ".
The system will be deactivated
automatically if a trailer is attached or a
bicycle carrier is fitted on a towbar (vehicle
fitted with a towbar installed in line with
the manufacturer's recommendations).
The parking sensors are deactivated while
the Park Assist system is measuring a
space.
For more information on Park Assist ,
refer to the corresponding section.
Operating limits
- Certain obstacles located in the sensors' blind spots may not be detected or no
longer be detected during the manoeuvre.
-

S
ounds such as those emitted by noisy
vehicles and machinery (e.g. lorries,
pneumatic drills, etc.) may inter fere with the
vehicle's sensors. -

C
ertain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
-
A
ccumulated snow or dead leaves on the
road sur face can inter fere with the vehicle's
sensors.
-
A f
ront or rear impact to the vehicle can
distort the settings of the sensors, which is
not always detected by the system: distance
measurements may be incorrect.
-
T
he tilting of the vehicle if the boot is
very loaded can affect the distance
measurements.
-
T
he sensors may be affected by poor
weather conditions (heavy rain, thick fog,
snowfall, etc.).
Recommendations on care
In bad or wintry weather, ensure that the
sensors are not covered with mud, ice or
snow. When reverse gear is engaged, an
audible signal (long beep) indicates that
the sensors may be dirty.

127
Operating fault
If a fault occurs when shifting
to reverse, this warning lamp
comes on in the instrument panel,
accompanied by a message and an
audible signal (short beep).
Contact a CITROËN dealer or a qualified
workshop
to have the system checked.
Reversing camera
The reversing camera function may be
supplemented with parking sensors.
The reversing camera cannot, in any
circumstances, replace the need for vigilance
on the part of the driver.
They are represented by lines marked "on
the ground" and do not allow the position
of the vehicle to be determined relative to
tall obstacles (for example: other vehicles,
e t c .) .
Some distortion of the image is normal.
It is normal to have part of the number
plate showing in the bottom of the screen. The green lines 3 represent distances of about
one and two metres beyond the edge of your
vehicle's rear bumper.
The turquoise blue curves 4 represent the
maximum turning circle.
Opening the tailgate causes the display to
disappear.
Clean the reversing camera regularly
using a soft, dry cloth.
High pressure washing
When washing your vehicle, keep the
lance at least 30 cm away from the
camera lens.
High pressure washing
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.
The reversing camera is activated automatically
when reverse gear is engaged.
The image is displayed on the touch screen. The superimposed representation of guide
lines helps with the manoeuvre.
The blue lines 1 represent the general direction
of the vehicle (the gap represents the width of
your vehicle except for the door mirrors).
The red line 2 represents a distance of about
30 cm beyond the edge of your vehicle's rear
b u m p e r.
Park Assist
This system provides active parking
assistance: it detects a parking space and then
steers in the appropriate direction to park in
this space while the driver controls the driving
direction, engagement of gears, acceleration
and braking.
To assist the driver in monitoring the
correct manoeuvring operation, the system
automatically triggers the display of the rear
view camera and the activation of the parking
sensors.

This system is a manoeuvring aid that
cannot under any circumstances replace
the vigilance of the driver.
The driver must remain in control of
their vehicle. They must always check
the surroundings of the vehicle before
undertaking a manoeuvre and ensure that
the space remains clear during the entire
manoeuvre.
The system per forms the measurements of
available parking spaces and calculations of
distances to obstacles using ultrasonic sensors
built in the front and rear bumpers of the
vehicle.
The system assists with the following
manoeuvres:Operation

Parking space search
F 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 stops over this limit.
The function automatically deactivates once
the vehicle speed exceeds 31 mph (50 km/h).
For "parallel" parking, the space must at
a minimum be equal to the length of your
vehicle plus 0.60 m.
For "bay" parking, the width of the space
must be equal to the width of your vehicle
plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle menu
of the touch screen, 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.
