Fuel tank
Tank capacity: approximately 45 litres.
I f you have put the wrong fuel in your
vehicle, you must have the fuel tank
drained and filled with the correct fuel
before star ting the engine.
Low fuel level
When the low fuel level in the
tank is reached, this warning lamp
comes on in the instrument panel,
accompanied by an audible warning
and a message.
When it first comes on, about 5


litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied
by a message and an audible signal, until
a sufficient addition of fuel is made. This
audible signal and message are repeated with
increasing frequency as the fuel level drops
and approaches " 0".
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 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.
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:

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
aluminium 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:
Original tyre size Chain types195/65 R15 Maximum 9
mm link
195/60 R16
205/60 R16 Cannot be fitted with
chains
215 / 5 0 R17
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.Towbar with quickly
detachable towball
No tools are required to install or remove the
towball on this genuine towbar system.

Before each use
Check that the ball joint is correctly fitted,
verifying the follow points:
- the green mark on the star wheel is in
line with the white mark on the towball,
-

t
he star wheel is in contact with the
towball (position A ),
-

t
he security key lock is on and the key
removed; the star wheel can no longer
be operated,
-

t
he towball must not be able to move in
its carrier; test by shaking it with your
hand.
If the towball is not locked, the trailer can
detach – Risk of accident! During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the maximum authorised
weight for the vehicle – the Gross Train
Weight or GTW.
It is essential that the maximum
authorised load be complied with on the
towing device: if it is exceeded, this device
may detach from the vehicle - Risk of
accident!
Check that the trailer lamps work
c o r r e c t l y.
Before setting off, check the adjustment of
the headlamp beam height.
For more information on Headlamp
adjustment
, refer to the corresponding
section.
Following use
When travelling without a trailer or load
on a towbar-mounted carrier, the towball
must be removed and the protective plug
inserted in the carrier. This measure
applies particularly where the towball
might obscure visibility of the number
plate or its lighting.Fitting the towball

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
load which can be towed must be reduced by
10% per 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 towbar is not fitted by a CITROËN
dealer, it must still be fitted in accordance
with the vehicle manufacturer's
instructions.
Certain driving assistance or manoeuvring
assistance functions are automatically
disabled if an approved towbar is used.

Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the fluid has frozen, it can be used once
it has completely thawed out at ambient
temperature.
Never keep AdBlue
® containers in your
vehicle.
Procedure
In cold weather, before per forming the top-up,
ensure that the temperature is above -11°C.
Otherwise the AdBlue
® may be frozen and so
cannot be poured into the tank.
Park your vehicle in a warmer area for a few
hours to allow the top-up to be carried out. F

After refilling
F Per form the operations in reverse order.
Important: in the event of a top-up after a
breakdown because of a lack of AdBlue,
you must wait around 5 minutes before
switching on the ignition, without opening
the driver’s door, unlocking the vehicle,
introducing the key into the ignition
switch, or introducing the key of the
