Under-inflation detection
The tyre under-inflation detection system
is a driving aid which does not replace the
need for vigilance on the part of the driver.This system does not relieve you of
the monthly check of the tyre inflation
pressures (including the spare) and before
a


long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including in particular the tyre
pressure label, refer to the corresponding
section. The tyre pressure measurement unit can be
configured with the MODE
button: in the "Tyre
pressure measurement" menu, select "psi/bar/
k Pa".
For more information on Vehicle
configuration , refer to the corresponding
section.
Under-inflation warning
This warning is indicated by
continuous illumination of this lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
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.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a

drop in the inflation pressure of one
or more tyres. In the event of a
problem with one of the tyres,
depending on equipment the symbol or the
message appears to identify it.

Compatibility of fuels

Fuel used for Diesel
engines
The diesel engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations.Diesel fuel that meets standard
EN590
mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7% Fatty Acid
Methyl Ester).
Diesel fuel that meets standard
EN16734
mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester).
Paraffinic Diesel fuel that meets
standard EN15940
mixed with
a
biofuel that meets standard
EN14214 (possibly containing up to
7% Fatty Acid Methyl Ester). For more information, contact a
CITROËN
dealer or a
qualified workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel…) is strictly prohibited (risk
of damage to the engine and fuel system).
The only Diesel additives authorised
for use are those that meet the
B715000


standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a
little while.
The use of B20

or B30

fuel meeting
standard EN16709

is possible in
your Diesel engine. However, this
use, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
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, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.

For more information on the Technical
data of the vehicle and particularly on
weights and towable loads, refer to the
corresponding section.
You will then have information on your vehicle's
ability to tow a
trailer, a caravan, a boat, etc.
We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved from
the design stage of your vehicle, and
that the fitting of the towbar is entrusted
to a
member of the CITROËN dealer
network.
These genuine towbars are compatible
with the operation of the rear parking
sensors and the reversing camera, if your
vehicle is so equipped.
If the towbar is not fitted by a
CITROËN
dealer, it must still be fitted in accordance
with the vehicle manufacturer's
instructions.Towbar with quickly

Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a
heater for the
AdBlue
® tank, allowing you to continue
driving in very cold conditions.
Topping up with AdBlue®
Before topping up, please read the
following warnings carefully.
Precautions for use
AdBlue® is a urea-based solution. This fluid
is
non-flammable, colourless and odourless
(stored in a
cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In
the event of contact with the eyes, immediately
rinse 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 exterior temperature,
for example), the risk of ammonia being
released cannot be excluded: do not inhale
the vapours. Ammonia has an irritant effect on
mucous membranes (eyes, nose and throat).
AdBlue® (BlueHDi
engines)
To respect the environment and ensure
compliance with the Euro 6
standard, without
adversely affecting the per formance or fuel
consumption of Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a
system that associates SCR (Selective
Catalytic Reduction) with a
Diesel particle filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid 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 contained in a special tank with
a
capacity of approximately 14 litres.
It has an exterior filler located behind the fuel
filler flap below the fuel filler cap and closed
with a

blue filler cap .
An alarm system is triggered once the
remaining range is 1,500 (2,400 km), in other
words once the reser ve level is reached. Once the AdBlue
® tank is empty, a
regulatory device prevents the engine
from being restarted.
If the SCR system is faulty, the level of
emissions from your vehicle no longer
meet the Euro 6

regulations: 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: having travelled 250 miles
(400 km), a device will be triggered
automatically to prevent the engine from
starting.
