Blind Spot Detection
This system warns the driver of the presence
of another vehicle in the blind spots of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A fixed 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
relative distances and 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
The function is activated and
deactivated in the Driving menu of
the touch screen.
When the function is activated,
this indicator lamp comes on in the
instrument panel.
The state of the system stays in memory when
switching off the ignition.
The system is automatically deactivated
when towing with a
towing device
approved by CITROËN.
Operation
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by an orange warning lamp
coming on in the relevant door mirror, as soon
as a
vehicle – car, lorry, cycle – 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 the 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
he traffic is flowing normally,
-

ov
ertaking 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.

Active Blind Spot
Monitoring System
(depending on version)
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you cross a lane marking
with the direction indicators on, to help you
avoid a


collision.
Conditions for operation
The following systems must be activated:
- B lind Spot Detection,
-
L

ane Departure Warning System.
The speed of the vehicle must be between
40
and 87 mph (65 and 140 km/h) inclusive.
Fatigue detection system
Take a break as soon as you feel tired or at
l east every two hours.
Depending on version, the function relies either
on the "Driver Attention Warning" system alone
or combined with the "Driver Attention Alert"
system.
These systems cannot in any circumstances
replace the need for vigilance on the part
of the driver who must remain in control
of their decisions. In no case can these
systems keep the driver awake or prevent
them from falling asleep at the wheel.
It is the driver's responsibility to stop if they
feel tired.
Activation/Deactivation
These functions are activated and
deactivated in the Driving menu of
the touch screen.
The state of the system stays in the memory
when the ignition is switched off.
Driver Attention Warning
The system triggers an alert once it
detects that the driver has not taken
a
break after two hours of driving at
a
speed above 40 mph (65 km/h).This alert is issued via the display of
a
message encouraging you to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped.
The system resets itself if one of the following
conditions is met:
-
e
ngine running, the vehicle has been
stationary for more than 15

minutes,
-
t
he ignition has been switched off for a few
minutes,
-
t
he driver's seat belt is unfastened and their
door is open.
As soon as the speed of the vehicle drops
below 40 mph (65 km/h), the system goes
into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Alert
Depending on version, the "Driver Attention
Warning" may be combined with the "Driver
Attention Alert".

Driving

176
Using a camera placed at the top
o f the windscreen, the system
assesses the driver's level of
vigilance by identifying variations
in trajectory compared to the lane
markings.
This system is particularly suited to fast roads
(speed higher than 40
mph (65 km/h)).
When the system interprets the behaviour of
the vehicle as indicating a
certain fatigue or
inattention threshold on the part of the driver, it
triggers the first level of alert.
The driver is then alerted by the message
" Ta k e c a r e ! ", accompanied by an audible
signal. After three first level alerts, the system triggers
a
new alert with the message "
Take a break!
",
accompanied by a more pronounced audible
signal.
In certain driving conditions (poor road
sur face or strong winds), the system may
give alerts independent of the driver's
level of vigilance.
The following situations may interfere with
the operation of the system or prevent it
working:
-

p
oor visibility (inadequate lighting of
the roadway, falling snow, heavy rain,
dense fog, etc.),
-

d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a
damp
road, leaving a
tunnel, alternating
shade and light, etc.),
-

w
indscreen area located in front of the
camera dirty, misted up, frost-covered,
snow-covered, damaged or covered by
a


s t i c ke r,
-
l

ane markings absent, worn, hidden
(snow, mud) or multiple (roadworks,
e t c .),
-

c
lose to the vehicle ahead (lane
markings not detected),
-

r
oads that are narrow, winding, etc.Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.
Parking sensors
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.
Driving

178
The rear parking sensors system will
be deactivated automatically if a trailer
or bicycle carrier is connected to
a
towing device installed in line with the
manufacturer's recommendations.
In this case, the outline of a
trailer is
displayed at the rear of the image of the
vehicle.
The parking sensors are deactivated while the
Park Assist system is measuring a
space.
For more information on the Park Assist , refer
to the corresponding section.
Operating limits
- A front 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.).
Operating fault
If the system fails, when reverse
gear is engaged this warning lamp
flashes for a
few seconds before
lighting up continuously, together
with the Service warning lamp.
A message appears, accompanied by an
audible signal.
Contact a
CITROËN dealer or a qualified
workshop. In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or
snow.
When reverse gear is engaged, an audible
signal (long beep) indicates that the
sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking sensor
system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30
cm away from the
sensors.

C

ertain 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.

This system is a visual aid that cannot in
a ny circumstances replace the need for
vigilance on the part of the driver.
The images provided by the camera(s)
may be distorted by the relief. The
presence of areas in shadow, bright
sunlight, or poor lighting conditions may
make the image dark and reduce contrast.
Forward vision
The camera situated on the front bumper is
activated and the views of the area to the
front left and the area to the front right of your
vehicle appear simultaneously in the instrument
panel.
Rear vision
The camera situated on the tailgate is activated
and the view of the area behind your vehicle is
displayed in the instrument panel and behaves
as a
reversing camera, regardless of the
position of the gear selector.
The blue outline represents the width of
your vehicle (without mirrors): its orientation
depends on the position of the steering wheel.
The red line represents the distance of 30 cm)
from the rear bumper and the two green lines
the distances of 1 m and 2 m respectively from
the rear bumper.
The rear vision is displayed automatically
when reverse gear is engaged, regardless
of the state of the system.
Vision 360
The cameras situated on the front and rear
bumpers as well as those below the door
mirrors activate and a view from above of your
vehicle in its close environment is generated
and is displayed in the instrument panel.
Opening a door or the tailgate will disrupt the
3 60 and rear views.
Installation of the very cold climate screen will
alter the image transmitted by the front camera.

Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could result in an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a
garage or heated
workshop for a
little while.
Travelling abroad
Certain fuels could damage your vehicle's
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For any additional information, contact a
