6Activating the function deactivates the Blind Spot Monitoring System.
You can deactivate the function at any time until the parking space entry or exit 
manoeuvre begins, by pressing the arrow 
located in the top left-hand corner of the 
display page.
Selecting the type of manoeuvre 
 
A manoeuvre selection page is displayed on the 
touch screen: by default, the "Entry" page if the 
vehicle has been running since the ignition was 
switched on, otherwise, the "Exit" page.
► Select the type and side of the manoeuvre to activate the parking space search.
The selected manoeuvre can be changed at 
any time, even while searching for an available 
space.
Parking space search
► You should drive at a distance of between 0.50 m and 1.50 m from the row of parked vehicles, without ever exceeding 19 mph (30 km/h), until the system finds an available space.
The parking space search is suspended at 
higher speeds. The function is automatically 
deactivated if the vehicle speed exceeds 31 mph 
(50 km/h).
For "parallel" parking, the space must 
measure at least the length of your 
vehicle plus 0.60 m.
For "bay" parking, the space must be at least 
as wide as your vehicle plus 0.70 m.
If the parking sensors function has been 
deactivated in the  Driving/Vehicle touch 
screen menu, it will be automatically 
reactivated when the system is activated.
 
 
When the system finds an available space, " OK" 
is displayed on the parking view, accompanied 
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle“, 
accompanied by the “ STOP” sign and an audible 
signal.
Once the vehicle has stopped, an instructions 
page is displayed on the screen.
► To prepare for the manoeuvre, follow the instructions. 
The start of the manoeuvre is indicated by the 
"Manoeuvre under way" onscreen message 
and an accompanying audible signal.
 Reversing is indicated by this message: 
“Release the steering wheel, reverse ”.
The Top Rear Vision and the parking sensors 
are automatically activated to help you monitor 
the area immediately surrounding your vehicle 
during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering.  It gives instructions on the manoeuvring direction 
when starting "parallel" entry and exit parking 
manoeuvres, and for all "bay" entry manoeuvres.
These instructions are displayed as a symbol 
accompanied by a message:
"Reverse".   
Page 122 of 244

120
Driving
“Go forwards". 
The manoeuvring status is indicated by these 
symbols:
Manoeuvre in progress (green). 
Manoeuvre cancelled or finished (red) (the arrows indicate that the driver must 
resume control of the vehicle).
The maximum speeds during manoeuvres are 
indicated by these symbols:
75 mph or 7 km/h, for parking space entry. 
53 mph or 5 km/h, for parking space exit. 
During manoeuvring phases, the steering 
wheel performs rapid turns: do not hold 
the steering wheel or put your hands between 
the spokes of the steering wheel. Watch out 
for any objects that could interfere with the 
manoeuvre (loose clothing, scarf, tie, etc.). 
Risk of injury!
It is the driver's responsibility to constantly 
monitor the traffic, especially vehicles coming 
towards you.
The driver should check that no objects or 
people are obstructing the vehicle’s path.
The images from the camera(s)  displayed on the touch screen may be 
distorted by the terrain.
In shady areas, or in inadequate sunlight 
or lighting conditions, the image may be 
darkened and with lower contrast.
The manoeuvre can be permanently interrupted 
at any time, either by the driver or automatically 
by the system.
Interruption by the driver:
– taking over control of the steering.– activating the direction indicator lamps on the opposite side to that of the manoeuvre.– unfastening the driver's seat belt.– switching off the ignition.Interruption by the system:– vehicle exceeding the speed limit of 5 mph (7 km/h) during parking space entry manoeuvres, or 3 mph (5 km/h) during parking space exit manoeuvres.– activation of anti-slip regulation on a slippery road.
– opening of a door or the boot.– engine stall.– system malfunction.– after 10 manoeuvres to enter or exit a parallel parking space and after 7 manoeuvres to enter a 
parking bay.
Interrupting the manoeuvre automatically 
deactivates the function. The manoeuvre symbol is displayed in red, 
accompanied by the "
Manoeuvre cancelled" 
message on the touch screen.
A message prompts the driver to take back 
control of the vehicle.
End of the parking space entry or exit 
manoeuvre
The vehicle stops as soon as the manoeuvre is 
completed.
The manoeuvre symbol is displayed in red, 
accompanied by the message “ Manoeuvre 
completed” on the touch screen.
When entering a parking space, the driver may 
be required to complete the manoeuvre.
Operating limits
– The system may suggest an unsuitable parking space (No Parking area, work in 
progress with damaged road surface, location 
alongside a ditch, etc.).
– The system may indicate that a space has been found but not offer it because of a fixed 
obstacle on the opposite side of the manoeuvre, 
which would not allow the vehicle to follow the 
necessary trajectory for parking.
– The system may indicate that a space has been found but not engage the manoeuvre 
because the road is too narrow.
– The system is not designed to perform the parking manoeuvre on a sharp bend.– The system does not detect spaces that are much larger than the vehicle or are bounded by 
obstacles that are very low (pavements, studs, etc.) or very thin (trees, posts, wire fences, etc.).–  Certain obstacles located in the sensors’ blind spots may not be detected or may no longer be 
detected during the manoeuvre.
– Certain materials (fabrics) absorb sound waves: pedestrians may not be detected.– A front or rear impact to the vehicle can upset the sensors’ settings, which is not always 
detected by the system: distance measurements 
may be distorted.
–  If the boot is heavily loaded, the vehicle may tilt, affecting distance measurements.
The vehicle's sensors and camera(s) may be 
impaired by:
– accumulated snow or fallen leaves on the road,– adverse weather conditions (heavy rain, thick fog, falling snow),– noise interference from noisy vehicles and machinery (lorries, pneumatic drills, etc.).
Do not use the function under the 
following exterior conditions:
– Alongside a soft shoulder (e.g. ditch) or quay or on the edge of a drop.–  When the road surface is slippery (e.g. ice).
If any of the following malfunctions 
occurs, do not use the system:
– If a tyre is under-inflated.– If one of the bumpers is damaged.– If one of the cameras is faulty.

or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the formation of paraffins in summer-type Diesel  fuels could prevent the engine from operating 
correctly. In these temperature conditions, use 
winter-type Diesel fuel and keep the fuel tank 
more than 50 % full.At temperatures below -15 °C (+5 °F) to avoid problems starting, it is best to park the vehicle 
under shelter (heated garage).
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 all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 45 litres.
Reserve level: approximately 5 litres.
Low fuel level
/2 
1 1When the low fuel level is reached, one of these warning lamps comes 
on on the instrument panel, accompanied by an 
onscreen message and an audible signal. When 
it first comes on, about 5 litres of fuel remain.
Until sufficient fuel is added, this warning lamp 
appears every time the ignition is switched on, 
accompanied by an onscreen message and 
an audible signal. When driving, this message 
and audible signal are repeated with increasing 
frequency as the fuel level drops towards  0.
You must refuel as soon as possible to avoid 
running out of fuel.
For more information on  Running out of fuel 
(Diesel), refer to the corresponding section.
Stop & Start
Never refuel with the engine in STOP 
mode; you must switch off the ignition.
Refuelling
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 vacuum is entirely 
normal, resulting from the sealing of the fuel 
system.
To refuel in complete safety:
► You must switch off the engine. 
   
Page 126 of 244

124
Practical information
► With the vehicle unlocked, press the rear-central part of the filler flap to open it.► Take care to select the pump that delivers the correct fuel type for the vehicle's engine (see a 
reminder label on the inside of the filler flap).
► Turn the filler cap to the left. 
 
► Remove the filler cap and hang it on its carrier (on the filler flap).► Introduce the filler nozzle and push it in as far as possible before starting to refuel (risk of 
blowback).
► Fill the tank.Do not continue past the third cut-off of the 
nozzle, as this may cause malfunctions.
► Refit the filler cap.► Turn it to the right.► Push the filler flap to close it.
If you have put in the wrong fuel for the 
vehicle, you must have the fuel tank 
drained and filled with the correct fuel before 
starting the engine. The vehicle is fitted with a catalytic converter, a 
device which helps to reduce the level of harmful 
emissions in the exhaust gases.
For petrol engines, you must use unleaded 
fuel.
The filler neck is narrower, admitting unleaded 
petrol nozzles only.
Fuel cut-off
Your vehicle is equipped with a safety device 
which cuts off the fuel supply in the event of a 
collision.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank 
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention 
device is visible when the filler cap is removed.
Operation 
 
When a petrol filler nozzle is inserted into the 
fuel filler neck of a Diesel vehicle, it comes into 
contact with the flap. The system remains closed 
and prevents filling.
Do not persist but introduce a Diesel type 
filler nozzle.
It remains possible to use a fuel jerrycan 
to fill the tank.
Travelling abroad
As Diesel fuel pump nozzles may be 
different in other countries, the presence 
of the misfuel prevention device may make 
refuelling impossible.
Before travelling abroad, it is advisable to 
check with a CITROËN dealer if the vehicle is 
suitable for the distribution equipment of the 
countries visited.
Snow chains
In wintry conditions, snow chains improve 
traction as well as the behaviour of the vehicle 
when braking.
The snow chains must be fitted only to  the front wheels. They must never be 
fitted to "space-saver" type spare wheels.
Take account of the legislation specific to  each country on the use of snow chains 
and the maximum authorised speed.
Use only the chains designed to be fitted to the type of wheel fitted to the vehicle:
Original tyre size Chain types
195/65 R15
Maximum 9 mm link
195/60 R16
205/60 R16 Cannot be fitted with 
chains
215/50 R17
For more information on snow chains, contact a 
CITROËN dealer or a qualified workshop.
Installation tips 
►  To fit the chains during a journey, stop the vehicle on a flat surface on the side of the road.► Apply the parking brake and position any wheel chocks under the wheels to prevent 
movement of the vehicle.
►  Fit the chains following the instructions provided by the manufacturer.► Move off gently and drive for a few moments, without exceeding 31 mph (50 km/h).► Stop the vehicle and check that the snow chains are correctly tightened.
It is strongly recommended that before 
you leave, you practise fitting the snow 
chains on a level and dry surface.
Avoid driving with snow chains on roads  that have been cleared of snow to avoid 
damaging the vehicle's tyres and the road

boot.
Go to a CITROËN dealer or a qualified 
workshop for any work on the towbar system.
Towing  device
Load distribution► Distribute 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 load which 
can be towed must be reduced by 10% per 
1,000 metres of altitude.
Use towing devices and their genuine 
wiring harnesses approved by CITROËN. 
It is recommended that the installation be 
performed by a CITROËN dealer or a 
qualified workshop.
If not fitted by a CITROËN dealer, it 
must still be fitted in accordance with the 
manufacturer's instructions.
Certain driving or manoeuvring aid functions 
are automatically deactivated if an approved 
towing system is used.
Observe the maximum authorised 
towable weight, indicated on the 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 (towball) also includes the 
use of accessories (bicycle carriers, tow 
boxes, etc.).
Observe the legislation in force in the 
country where you are driving.
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
This system manages the duration of use of 
certain functions, in order to conserve a sufficient 
level of charge in the battery with the ignition off.
After switching off the engine, you can still 
use functions such as the audio and telematic 
system, the wipers and the dipped beam 
headlamps or courtesy lamps, for a combined 
duration of approximately 40 minutes.
Switching  to this mode
A message appears in the instrument panel 
screen indicating that the vehicle has switched to 
economy mode and the active functions are put 
on standby.
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 are automatically reactivated the 
next time the vehicle is used.
To restore the use of these functions 
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
–  For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to 
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or 
continuously restarting the engine.
A flat battery prevents the engine from 
starting.
For more information on the 
12 V battery, 
refer to the corresponding section.
Roof bars
For safety reasons and to avoid 
damaging the roof, it is essential to use 
the transverse bars approved for your vehicle.
