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
- A front 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.).
Operating fault
If the system fails, when reverse
gear is engaged this warning lamp
flashes for a
few seconds before
lighting up continuously, together
with the Service warning lamp.
A message appears, accompanied by an
audible signal.
Contact a
CITROËN dealer or a qualified
workshop. In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or
snow.
When reverse gear is engaged, an audible
signal (long beep) indicates that the
sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking sensor
system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30
cm away from the
sensors.

Operating faults
In the event of a fault, this warning
l amp flashes for a few seconds,
accompanied by an audible signal.
In the event of a
fault with the
power steering, this warning lamp
is displayed in the instrument panel,
accompanied by a


message.
If the lateral distance between your vehicle
and the space is too great, the system may
not be able to measure the space.
Any object projecting beyond the dimensions
of the vehicle (e.g. a ladder on the roof or
a towball) will not be taken into account by
the Park Assist system during a
manoeuvre.
In bad weather or in winter, ensure that
the sensors are not covered by dirt, ice or
snow.
In the event of a fault, have the system
checked by a
CITROËN dealer or
a


qualified workshop. High pressure jet washing

Fuel
Fuel tank capacity: approximately 57 litres
(petrol) or 55 litres (Diesel).
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 lights
up orange.
When it first comes on there remains
approximately 6


litres of fuel in the tank.
Until sufficient fuel has been added, this
warning lamp appears every time the ignition
is switched on, accompanied by an audible
warning and a
message. This audible warning
and this message are repeated with increasing
frequency as the fuel level drops towards " 0".
Refuel as soon as possible to avoid running
out.
Refilling
A self-adhesive label on the inner face of the
filler flap reminds you of the type of fuel to use,
depending on your engine.
Additions of fuel must be of at least 5
litres, in
order to be registered by the fuel gauge. To refuel in complete safety:
F

Y
ou must switch off the engine.
F
W
ith the vehicle unlocked, press the rear
edge of the flap to open it (the filler cap is
a part of it).
F T ake care to select the pump that delivers
the correct type of fuel for your vehicle.
F

I
nsert the nozzle so as to push in the metal
non-return flap.
F

M
ake sure that the nozzle is pushed in as
far as possible before starting to refuel (risk
of blowback). If you are filling your tank to the top, do not
continue after the 3
rd cut- off of the nozzle;
this could cause malfunctions.
Your 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, allowing only
unleaded petrol nozzles to be introduced.
If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct
fuel before star ting the engine.
Fuel cut- of f
Your vehicle is fitted with a safety system that
c uts off the supply of fuel in the event of an
impact.
Opening the filler flap may create a

noise
caused by an inrush of air. This is entirely
normal and results from the sealing of the fuel
system. F
H
old it in this position throughout the filling
operation.
F
P
ush the filler flap to close it.
With Stop & Start, never refuel with the
engine in STOP mode; you must switch
off the ignition with the "START/STOP"
button.

Towing device
Load distribution
F 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
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.
Important : for versions equipped with
the motorised tailgate with "Hands-Free
Tailgate Access" function, if a towing
device other than a genuine CITROËN
one is installed, it is imperative to
visit a CITROËN dealer or a qualified
workshop to recalibrate the detection
system: risk of "Hands-Free Tailgate
Access" function failure.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system 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 (towball)
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.
