Misfuel prevention (Diesel)*
Operation
When a petrol filler nozzle is introduced into the
fuel filler neck of your 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.
* Depending on country of sale. Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.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
s l ow l y.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, 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 want to travel.

In the event of a fault with the the SCR emissions control system
In the event of the detection
of a faultDuring an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
A system that prevents engine starting is
activated automatically from 650 miles
(1 100 km) after confirmation of a fault
with the SCR emissions control system.
Have the system checked by a CITROËN
dealer or a qualified workshop as soon as
possible.
If it is a temporary fault, the alert
disappears once the exhaust gas
emissions return to normal.
When switching on the ignition, the UREA,
SERVICE and diagnostic warning lamps comes
on, accompanied by an audible signal and the
display of a message "Emissions fault" to signal
a fault with the emissions control system.
If a fault with the SCR system is confirmed
(after 30 miles (50 km) covered with the
permanent display of the message signalling
a fault), when switching on the ignition, the
SERVICE and engine diagnostic warning lamps
come on and the UREA warning lamp flashes,
accompanied by an audible signal and the
display of a message (e.g.: "Emissions fault:
Starting prevented in 150 miles") indicating the
remaining range express in miles or kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
If you fail to do this, there is a risk that you will
not be able to start your engine.

F Obtain a bottle of AdBlue®. After first
checking the use-by date, read carefully
the instructions on use on the label before
pouring the contents of the bottle into your
vehicle's AdBlue
® tank.
Important : if your vehicle's AdBlue
®
tank is completely empty - which is
confirmed by the alert messages and
the impossibility of starting the engine,
you must add at least 3.8 litres (so
two 1.89 litre bottles). If any additive is split or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the additive has crystallised, clean it
off using a sponge and hot water.
Important:
in the event of a top-up after
a breakdown because of a lack of
additive , signalled by the message "Top
up emissions additive: Starting prevented",
you must wait around 5 minutes before
switching on the ignition, without opening
the driver's door, locking the vehicle
or introducing the key into the ignition
switch .
Switch on the ignition, then, after
10

seconds, start the engine.

Access to the battery
Procedure for starting the engine using another battery or charging a discharged battery.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITROËN dealer
or a qualified workshop is essential
when replacing or disconnecting the
battery.
After refitting the battery, the Stop &
Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge
of the battery (up to about 8 hours).
Before doing any work
Immobilise the vehicle: apply the
parking brake, put the gearbox in
neutral, then switch off the ignition.
Check that all electrical equipment is
switched off.

The batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with
household waste.
Take used remote control batteries and
vehicle batteries to a special collection point.Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
Do not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands afterwards.
It is advisable to disconnect the battery
if the vehicle is to be left unused for
more than one month.
Do not push the vehicle to start the
engine if the vehicle is fitted with the
electronic gearbox.Charging the battery using
a battery charger
F Disconnect the battery from the vehicle.
F F ollow the instructions for use provided by
the manufacturer of the charger.

Driving advice
Distribution of loads
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. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
When not towing a trailer, remove the
quickly-detachable tow ball before
driving.
