Collision Risk Alert and
Active Safety Brake
Activation and operating
conditions
The system is activated from 3 mph (5 km/h).
It takes account of:
-
r
egistered vehicles running in the same
direction or stationary,
-

p
edestrians in the traffic lane (bicycles,
motorcycles, animals and objects on the
road are not necessarily detected).
This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of the
traffic, observing the driving regulations.
This system does not avoid the need for
vigilance on the part of the driver.
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.
This system is a driving aid that includes three
functions.
Collision Risk Alert:
it warns the driver if their
vehicle is at risk of collision with the vehicle in
front or a pedestrian present in their traffic lane.
Intelligent emergency braking assistance :
it supplements the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, it contributes
towards avoiding a collision or limiting
its severity by reducing the speed of your
vehicle.
The vehicle has a camera located at the top of
the windscreen. In the following cases, deactivating the
system via the vehicle's configuration menu is
recommended:
-
w hen towing a trailer,
- w hen carrying long objects on roof bars or a
roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling stand
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-
fo

llowing impact damage to the windscreen
close to the detection camera,
-

i
f the brake lamps are not working.It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay alert and be
prepared to react at any time to avoid an
accident.

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.

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.

During the manoeuvre
The system takes over the vehicle's steering. It
gives instructions on the manoeuvring direction
when starting the entry and exit parallel parking
manoeuvres and for all entry manoeuvres for
bay parking."Reverse "
" Advance "
There instructions are displayed as a symbol
accompanied by a message:
The manoeuvring status is indicated by these
symbols:
5 mph or 7 km/h, for parking space
e nt r y. Manoeuvre in progress (green).
Manoeuvre cancelled or finished
(red) (the arrows indicate that the
driver must take back control of their
vehicle).
The maximum speed limit indications during
the manoeuvres are signalled by these
symbols: During a manoeuvre the steering wheel
rotates rapidly: do not hold the steering
wheel nor place your hand between the
spokes of the steering wheel. Watch out
for anything likely to block the manoeuvre
(loose and bulky clothing, scar ves, ties,
etc.) – Risks of injury!
It is the driver's responsibility to monitor
the state of the traffic continuously,
especially vehicles coming towards you.
The driver should check that no object
or person can hinder the advance of the
vehicle.
The images from the camera(s) displayed
on the touch screen 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
be of lower contrast.
The manoeuvre can be interrupted definitively
at any time, either by the action of the driver or
automatically by the system. By the action of the driver:

Fuel tank
Tank capacity:
- Pe trol: approximately 50 litres.
-

D
iesel: approximately 45 or 50 litres
(depending on version).
If you have put in the wrong fuel for
your vehicle, you must have the tank
drained and refilled with the correct
fuel before you star t the engine.
Low fuel level
When the low fuel level is reached,
this warning lamp in the instrument
panel comes on, accompanied by
an audible warning, a message and
the last bar of the fuel gauge flashes
in red.
When it first comes on, about 5 litres of fuel
remain in the tank.
Until sufficient fuel has been added, this
warning lamp appears every time the ignition
is switched on, accompanied by an audible
signal and a message. This audible warning
and message are repeated with increasing
frequency as the fuel level drops towards " 0".
You must refuel as soon as possible to avoid
running out. For more information on Running out of
fuel (Diesel)
, refer to the corresponding
section.
Refilling
A label on the inside of the fuel filler flap
reminds you of the type of fuel to use,
depending on your engine type.
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise
caused by an inrush of air. This is entirely
normal and results from the sealing of the fuel
system.
To refuel in complete safety:

It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging your vehicle's tyres and the
road sur face. If your vehicle is fitted with
alloy wheels, check that no part of the
chain or its fixings is in contact with the
wheel rim. Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Very cold climate screens
Removable protective screens which prevent
the accumulation of snow at the radiator
cooling fan.
Before fitting or removing a screen,
ensure that the engine is off and the
cooling fan has stopped.
It is recommended that the screens be
fitted and removed by a CITROËN dealer
or a qualified workshop.

Towing device
Load distribution
F D istribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10
% for every
1,000 metres of altitude.
Use towing devices and their genuine
harnesses approved by CITROËN. It is
recommended that the installation be
per formed by a CITROËN dealer or a
qualified workshop.
If the towing device is not fitted by
a CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing device is used. Obser ve the maximum authorised towable
weight, indicated on your vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data

section of this guide.
Complying with the maximum
authorised nose weight (ball joint)
also includes the use of accessories
(bicycle carriers, tow boxes, etc.).
Obser ve the legislation in force in the
country in which you are driving.
Remove the quickly detachable towball
when not towing a trailer.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system,
windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.
Entering the mode
A message appears on the touch screen
indicating that the vehicle has switched to
economy mode and the active functions are put
o n st a n d by.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free
system of your audio system.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
In order to restore the use of these functions
immediately, start the engine and let it run:

Practical information

148
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37 mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking the
levels and particularly on the level of
Diesel additive, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electronic 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.
Brake disc/drum wear
For information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units
as important as those in the braking
system, CITROËN selects and offers very
specific products.
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.
