accompanied by an alert message
and an audible signal.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on
the use of driving and manoeuvring aids
.
This system allows:
-

t
he driver to be warned that their vehicle is
at risk of collision with the vehicle in front,
a pedestrian or, depending on version, a
cyclist,
-

a c
ollision to be prevented, or its severity to
be limited, by reducing the vehicle's speed.
Driving

157
The system also takes motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road
are not necessarily detected.
This system is comprised of three functions:
-

C
ollision Risk Alert,
-
I

ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
The vehicle has a
multifunctional camera
located at the top of the windscreen, and,
depending on version, a radar located in the
front bumper. As soon as the system detects a
potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a
slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically
activated at every engine start.
This system can be deactivated or
activated via the Driving /Vehicle
menu of the touch screen.
Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a
message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be
deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required. In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
-

t
owing a trailer,
-
c
arrying long objects on roof bars or roof
rack,
-
w
ith snow chains fitted,
-
b
efore using an automatic car wash, with
the engine running,
-
b
efore placing the vehicle on a rolling road
in a workshop,
-
t
owed vehicle, engine running,
-
d
amaged front bumper (version with radar),
-
f
ollowing an impact to the windscreen close
to the detection camera.
The system is automatically deactivated
after the use of certain "space-saver"
type spare wheels is detected (smaller
diameter).
The system is automatically deactivated
after detection of a fault with the brake
pedal switch or with at least two brake
lamps.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.

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.

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
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.
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.

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

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.

If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is per fectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
Unless there is a
leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in case
of an issue, do not hesitate to have
the system checked by a
CITROËN
dealer or a
qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have
driven for more than 10
minutes or more
than 6

miles (10 kilometres) at over 31 mph
(50

km/h), add 0.3 bar (30 kPa) to the values
indicated on the label.

Practical information

195
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators , refer to the
corresponding sections.
Once the AdBlue
® tank is empty, a system
required by regulations prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from your vehicle will no longer
meet the Euro 6

standard: your vehicle
becomes polluting.
In the event of a

confirmed fault with the
SCR system, you must go to a
CITROËN
dealer or a

qualified workshop as soon
as possible: after travelling a
distance
of 685

miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a
heater for the
AdBlue
® tank, allowing you to continue
driving in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reser ve level has been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® fluid that meets the
ISO
22241
standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN
d
ealer or a

qualified workshop.
You can also visit a

ser vice station equipped
with AdBlue
® pumps specially designed for
passenger vehicles.
Recommendations on
storage
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never keep bottles or containers of
AdBlue
® in your vehicle.
Precautions for use
AdBlue® is a urea-based solution. This liquid
is
non-flammable, colourless and odourless
(when kept in a
cool place).
In the event of contact with the skin, wash the
affected area with soap and water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15
minutes. If you feel
a

persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
AdBlue
® freezes below about -11°C and
deteriorates above 25°C. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.
