Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items in the bottom of the boot,
as close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit
a CITROËN dealer or a qualified workshop to
make your vehicle's level of nitrogen oxides
emissions compliant to the standard.

To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped with an
exhaust gas extraction system.
The additional heating switches off when
the battery voltage is low, so as to allow
engine starting.
The additional heating is fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
electronic circuits.
The additional heating is fitted with
a
temperature limiter which cuts off
the combustion in the event of engine
overheating due to a
lack of coolant.
Check the level and top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
F

T
o ensure that the air is distributed evenly,
keep the external air intake grilles at the
base of the windscreen, the nozzles, the
vents, the air outlets and the air extractor
in the boot free from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used for
regulation of the automatic air conditioning
system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact a
CITROËN
dealer or a
qualified workshop.
When towing the maximum load on a
steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.

Fuel system cut-off
In the event of a collision, a device
a utomatically cuts off the fuel supply to the
engine and the vehicle's electrical supply.
It switches on the hazard warning lamps and
the courtesy lamps, as well as unlocking the
doors.
Following an impact and before restoring
the supply, check that there is no leak of
fuel or sparks so as to avoid any risk of
fire.

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.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a
level drops significantly, have the
corresponding system checked by a
CITROËN
dealer or a
qualified workshop.
If you have to remove/refit the engine
cover, handle it with care to avoid
damaging the fixing clips.
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive. Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a
CITROËN dealer or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
Check this regularly and top up as
necessary between two oil changes

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.
