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:
-
t aking over control of the steering,
- a ctivating the direction indicator lamps on
the opposite side to that of the manoeuvre,
-

Recommendations on care
- Regularly check that the sensors and cameras are clean.
If necessary, clean the camera lenses with
a soft, dry cloth.
-

I
f using a high-pressure washer, do not
direct the lance less than 30 cm from the
sensors and cameras.
-

I
n bad weather, or during the winter, ensure
that the sensors and cameras are not
covered with mud, ice or snow.
Operating faults
When the function is not activated,
the button warning lamp flashing
and an audible signal indicates a
system fault.
If the fault occurs during the use of the system,
the warning lamp goes off.
If the fault in the parking sensors,
indicated by this warning lamp
coming on, occurs during use, it
causes the function to deactivate.
In the event of a fault, have the system checked
by a CITROËN dealer or a qualified workshop. In the event of a fault with the
power steering, this warning lamp
flashes in the instrument panel,
accompanied by a message.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure in all four
tyres, as soon as the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a drop in the pressure of one or more
tyres. The tyre under-inflation detection system
does not replace the need for vigilance on
the part of the driver.
This system still requires you to check the
tyre inflation pressure (including the spare
wheel) every month as well as before a
long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.

Compatibility of fuels
Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel
engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations: Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid Methyl
Ester),
Paraffinic Diesel fuel that meets
standard EN15940 mixed with a biofuel
that meets standard EN14214 (possibly
containing up to 7% Fatty Acid Methyl
Ester).
B20 or B30 fuel that meets the standard
EN16709 can be used with your Diesel
engine. However, the use of this
fuel, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
For more information, contact a CITROËN
dealer or a qualified workshop.
Diesel fuel that meets standard
EN590 mixed with a biofuel that meets
standard EN14214 (possibly containing
up to 7% Fatty Acid Methyl Ester), The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail 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
Cer tain fuels could damage the engine of
your vehicle.
In cer tain countries, the use of a par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.

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.
