Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label.
The tyre pressures must be checked
when the tyres are cold (vehicle
stopped for 1 hour or after driving for
less then 6 miles (10 km) at moderate
speed). Other wise, add 0.3 bar to the
values indicated on the label.
For more information on Identification
markings
, including the tyre pressure
label, refer to the corresponding
section. Driving with under-inflated tyres
increases fuel consumption.
Pressure sensors are located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.

Fuel tank
Capacity of the tank: approximately 71 litres*.
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
in the display screen. When it
first comes on, there remains
around 5 litres of fuel in the tank.

For a petrol engine with a catalytic

compulsory.

unleaded petrol nozzles can be put in.

Additions of fuel must be of at least
5
litres to be taken into account by the
fuel gauge.
Opening the filler cap may create a
noise of an inrush of air. This vacuum,
which is entirely normal, is caused by
the sealing of the fuel system.
With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key.
* 55 litres for Slovakia.
You must refuel to avoid running out of fuel.

servicing conditions referred to as
"Arduous conditions".
For more information, contact a CITROËN
dealer or a qualified workshop.
Travelling abroad
Cer tain fuels could damage the
engine of your vehicle. In cer tain
countries, the use of a par ticular fuel
may be required (specific octane
rating, specific sales name…) to
ensure correct operation of the
engine.
For any additional information, contact
your dealer.

Misfuel prevention (Diesel)*
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. 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.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
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
s l ow l y.
*

Depending on the country of sale.
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.

AdBlue® and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
SCR system
Using a fluid called AdBlue® containing urea, a
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment. The AdBlue
® is held in a special tank with
a capacity of about 17 litres: this provides
a driving range of about 12 500 miles
(20

000

km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2

400

km) before the tank is empty.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12

500

miles (20 000 km), it will be necessary
to top-up the AdBlue
®. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1

100 km), a system will be triggered
automatically to prevent engine starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.

Precautions in use
AdBlue® is a urea-based solution. This liquid is
non-flammable, colourless and odourless (kept
in a cool area).
In the event of contact with the skin, wash
the affected area with soap and water. In the
event of contact with the eyes, wash (irrigate)
the eyes with large amounts of water or with
an eye wash solution for at least 15 minutes.
If a burning sensation or irritation persists, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia
cannot be excluded: do not inhale the fluid.
Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat).
Keep AdBlue
® out of the reach of
children, in its original container or
bottle.
Never transfer AdBlue
® to another
container: it would lose its purity. Use only AdBlue
® fluid that meets the
ISO

22241 standard.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
The supply in a non-drip container or bottle
simplifies topping-up. You can obtain 1.89 litre
(half a US gallon) bottles or 5 litre containers
from a CITROËN

dealer or a qualified
workshop.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
Topping-up the AdBlue®
Filling the AdBlue® tank is an operation
included in every routine service on your
vehicle by a CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top-up the fluid between
services, more particularly if an alert (warning
lamps and a message) signals the requirement.
You can go to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.
