Active Safety Brake
Operation
- The vehicle's speed does not exceed 50   mph (80   km/h) when a   stationary vehicle 
or a
  cyclist is detected.
-
 
T
 he vehicle's speed is above 6   mph 
(10
  km/h) (versions with camera and radar) 
or between 6
  mph and 53   mph (10   km/h and 
85
  km/h) (versions with camera alone) when 
a
  moving vehicle is detected.If the camera and/or radar have 
confirmed the presence of a
  vehicle, 
a pedestrian or a
  cyclist, this 
warning lamp flashes (for about 
10
  seconds) when the function is 
acting on the vehicle's brakes.
With an automatic gearbox, in the event of 
automatic emergency braking until the vehicle 
comes to a
  complete stop, keep the brake 
pedal pressed down to prevent the vehicle from 
starting off again.
With a
  manual gearbox, in the event of 
automatic emergency braking until the vehicle 
comes to a
  complete stop, the engine may stall.
The driver can control the vehicle at any 
time by making a
  deliberate movement 
of the steering wheel and/or pressing the 
accelerator pedal. Operation of the function may be felt by 
slight vibration in the brake pedal.
If the vehicle comes to a
  complete stop, 
the automatic braking is maintained for 
1
  to 2   seconds.
Malfunction
In the event of a fault with the 
s ystem, you are alerted by the 
continuous illumination of this 
warning lamp, accompanied by the 
display of a
  message and an audible 
signal.
Contact a
  CITROËN dealer or 
a
  qualified workshop to have the 
system checked.
This function, also called automatic emergency 
braking, inter venes following the alert if the 
driver does not react quickly enough and does 
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid 
a
 
frontal collision by your vehicle where the 
driver fails to react.
The system operates under the following 
conditions:
-
 
T
he vehicle's speed does not exceed 
37
 
mph (60
 
km/h) when a
 
pedestrian is 
detected.
Fatigue detection system
Refer to the General recommendations on 
the use of driving and manoeuvring aids .
Take a
  break as soon as you feel tired or at 
least every two hours.
The function comprises the "Coffee Break 
Alert" system combined with the "Driver 
Attention Alert" system.

Driving  
Page 162 of 292

160
Activation/Deactivation
These functions are activated and 
deactivated in the Driving/Vehicle  
menu of the touch screen.
The state of the system stays in the memory 
when the ignition is switched off.
Coffee Break Alert
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
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 main 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 "
Driving at 
risk: 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 
from working:
- 
p
 oor visibility (inadequate lighting of 
the road, falling snow, heavy rain, 
dense fog, etc.),
-
 
d

Active Lane Departure 
Warning System
Refer to the General recommendations on 
the use of driving and manoeuvring aids .Using a
  camera located at the top of the 
windscreen to identify lane markings on the 
road and at the edges of the road (depending 
on version), the system corrects the trajectory 
of the vehicle while alerting the driver if it 
detects a   risk of unintentionally crossing a   line 
or hard shoulder (depending on version).
This system is particularly useful on motor ways 
and main roads.
Conditions for operation
The speed of the vehicle must be between 
40   and 112   mph (65   and 180   km/h).
The driver must hold the wheel with both 
hands.
The change of trajectory must not be 
accompanied by operation of the direction 
indicators.
The ESC system must not be faulty.
The ASR /DSC systems must be activated.
The system helps the driver only when 
there is a
  risk of the vehicle involuntarily 
wandering from the lane it is being driven 
in. It does not manage the safe driving 
distance, the speed of the vehicle or the 
brakes.
Operation
Once the system identifies a risk of the vehicle 
i nvoluntarily crossing one of the lane markings 
detected, it makes the correction to the 
trajectory required to return the vehicle to its 
initial path.
The driver will notice a
  turning movement of the 
steering wheel.
This warning lamp flashes during 
trajectory correction.
The driver can prevent the correction by 
keeping a
  firm grip on the wheel (during 
an avoiding manoeuvre, for example).
The correction is interrupted if the 
direction indicators are operated.
If the system detects that the driver is not 
holding the wheel firmly enough during 
an automatic correction of trajectory, 
it interrupts the correction. An alert is 
triggered to encourage the driver to take 
back control of the vehicle.

Driving situations and 
associated alerts
The table below describes the alerts and 
messages displayed depending on the driving 
situations.
The display of these alerts is not sequential. While the direction indicators are on and for 
a  few seconds after switching them off, the 
system considers that any change of trajectory 
is voluntary and no correction is triggered 
during this period.
However, with the Blind Spot Monitoring system 
activated, if the driver starts changing lanes 
and another vehicle is detected in the vehicle's 
blind spot, the system will correct the trajectory 
of the vehicle even though the direction 
indicators are on.

Active Blind Spot 
Monitoring System
Refer to the General recommendations on 
the use of driving and manoeuvring aids. 
Driving  
Page 167 of 292

165
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.
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 attempt to cross 
a
  lane marking with the direction indicator 
activated, to help you avoid a
  collision.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 anticipate their movements 
before deciding whether to change lane.
Activation/Deactivation
The function is activated and 
deactivated in the Driving/Vehicle  
menu of the touch screen.
The state of the system stays in the memory 
when switching off the ignition.
The system is automatically deactivated 
when towing with a
  towing device 
approved by CITROËN.
Operation
The alert is given by an orange warning lamp 
coming on in the relevant door mirror, as soon 
as a
  vehicle – car, lorry, bicycle – is detected.
A correction of trajectory will be felt if you 
attempt to cross a
  lane marking with the 
direction indicator flashing.
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) for the 
alert and between 40
  and 87   mph (65   and 
140
  km/h) for a   correction of trajectory,
-
 
t
 he system must be activated to trigger 
a
  change of trajectory,
-
 
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 towing a   trailer, a 
caravan, etc.
Sensors fitted in the front and rear bumpers 
monitor the blind spots.

Malfunction
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 or wintry weather, ensure that the 
sensors are not covered by 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.
The system is automatically deactivated 
when towing with a
  towing device 
approved by CITROËN.
If a
 
fault occurs, this warning lamp comes on 
in the instrument panel, accompanied by the 
display of a
 
message.
Contact a
 
CITROËN dealer or a
 
qualified 
workshop to have the system checked.
No alert will be given and no correction will be 
made in the following situations: -
 i
n the presence of non-moving objects 
(parked vehicles, barriers, street lamps, 
road signs, etc.),
-
 
w
ith vehicles moving in the opposite 
direction,
-
 
d
riving on a
 
winding road or a
 
sharp corner,
-
 
w
hen overtaking or being overtaken by 
a
 
very long vehicle (lorry, bus, etc.) which is 
both in the rear blind spot and 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,
-
 
i
f the Park Assist function is activated.

Parking sensors
Refer to the General recommendations on 
the use of driving and manoeuvring aids.
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 
present within the vehicle sensors' detection 
zone.
The proximity information is given by an 
intermittent audible signal, the frequency of which 
increases as the vehicle approaches the obstacle.
When the distance between the vehicle and 
the obstacle becomes less than about thirty 
centimetres, the audible signal becomes 
continuous.
The sound emitted by the speaker (right or left) 
allows you to identify the side on which the 
obstacle is located.
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.It supplements the audible signal by displaying 
bars on the screen that move progressively 
nearer to 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 an obstacle is no longer 
detected or when the speed of the vehicle 
exceeds 6
  mph (10   km/h).
6 
Driving  
Page 170 of 292

168
The sound emitted by the speaker (front or 
rear) locates the obstacle in relation to the 
vehicle, in front or behind.
Deactivation/Activation
The function is deactivated and 
activated in the Driving/Vehicle  
menu of the touch screen.
The state of the system stays in the memory 
when the ignition is switched off.
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
The tilting of the vehicle if the boot is very 
loaded can affect the distance measurements.
Malfunction
If a malfunction occurs, when 
s hifting to reverse, one of these 
warning lamps comes on in the 
instrument panel, accompanied by 
the display of a
  message and an 
audible signal (short beep).
If the malfunction occurs while the 
parking sensors are being used, it 
causes the function to deactivate.
Contact a
  CITROËN dealer or a   qualified 
workshop to have the system checked.
