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:
F

Y
ou must switch off the engine. F

If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition
using the key, or the START/STOP button
if your vehicle has
K
eyless Entry and
Starting.
Fuel cut- of f
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 the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
It remains possible to use a fuel can to fill
the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device and pour slowly. Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network whether
your vehicle is suitable for the fuel pumps
in the country in which you intend to travel.
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
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 in force in
your country on the use of snow chains
and the maximum authorised speed.

moments, without exceeding 31 mph
(50


km/h).
F

S
top your 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 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
