We recommend use of the automatic regulation 
of the air conditioning.
It permits automatic and optimised control 
of all of the following functions: air flow, 
temperature in the passenger compartment 
and air distribution, by means of various 
sensors (ambient temperature, sunshine). 
This eliminates any need for you to change 
your settings other than the temperature value 
displayed.
F Take care not to cover the sunshine 
sensor  A.
If you select the automatic mode   
(by pressing the "AUTO" control) and leave 
all of the vents open, optimum comfort will be 
maintained and humidity and condensation will 
be removed regardless of the exterior climatic 
conditions.
The temperature in the passenger compartment 
can only be lower than the ambient temperature 
if the air conditioning is on.
In order to be effective, the air conditioning must 
be used with the windows closed. If the vehicle 
has been parked in the sun for a long period 
and the interior temperature is very high, first 
ventilate the passenger compartment with the 
windows open for a few minutes, then close the 
windows.
Heating, ventilation and air conditioning recommendations
To keep the air conditioning system in 
good working order it is essential that it is 
operated at least once a month.
The air conditioning uses engine power 
during its operation. As a result, the fuel 
consumption of the vehicle increases.
In certain cases of particularly arduous use 
(e.g. towing the maximum load on a steep 
gradient in high temperatures), switching off 
the air conditioning saves engine power and 
improves the towing capacity.
Air inlet
Check that the exterior grille for the air inlet, 
at the bottom of the windscreen, is clean and 
free of dead leaves, snow, etc.
When washing the vehicle using a high 
pressure nozzle, avoid spraying at the air 
inlet. Maximum comfort is obtained by means of 
a good distribution of air in the passenger 
compartment, both in the front and in the rear.
To obtain a uniform distribution of air, take 
care not to block the exterior air intake grille 
located at the base of the windscreen, the 
vents, the air outlets under the front seats and 
the air extractor located behind the flaps in 
the boot.
The front and rear vents are fitted with 
thumbwheels to adjust the air flow and 
direction. We recommend that you leave all of 
the vents open.
Dust filter / Odour filter 
(active carbon)
There is a filter for excluding odours and 
dust.
This filter must be changed in line with the 
vehicle's servicing schedule. (Refer to the 
maintenance and warranty guide).

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.
You must refuel to avoid running out of fuel.
F  Press at the top left corner, then pull on its 
edge. While you are refuelling, the engine must be 
stopped and the ignition switched off.
F 
Turn the key a quarter turn to lock and 
unlock the filler cap.
F  When refuelling, place the cap on hook A .
F  Fill the tank, but do not persist after the 
third cut-off ; this could cause your vehicle 
to malfunction.
For a petrol engine with a catalytic 
converter,  the use of unleaded fuel is 
compulsory.
The filler neck is narrower to ensure that only 
unleaded petrol nozzles can be put in.
Opening the fuel flap Refuelling
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.

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.

adb lue® additive 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.
Presentation of the SCR system
Using an additive called AdBlue® containing 
urea, a catalytic converter turns up to 85% 
of nitrous oxides (NOx) into nitrogen and 
water, which are harmless to health and the 
environment. The ad
blue
® additive is held in a special 
tank located under the boot at the rear of 
the vehicle. It has a capacity of 17 litres: this 
provides a driving range of about 12 500 miles 
(20 000 km), after which an alert is triggered 
warning you when the reserve remaining is 
enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle 
by a CITROËN dealer or a qualified workshop, 
the ad blue
® additive tank is refilled in order to 
allow normal operation of the SCR system.
If the estimated mileage between two services 
is greater than 12 500 miles (20 000 km), we 
recommend that you go to a CITROËN dealer 
or a qualified workshop to have the necessary 
top-up carried out. o
nce the a db lue
® tank is empty, a 
system required by regulations prevents 
starting of the engine.
If the SCR is faulty, the level of 
emissions from your vehicle will no 
longer meet the Euro 6 standard: you 
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.

Precautions in use
The adblue® additive is an 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 ambient 
temperature, for example), the risk of release 
of ammonia cannot be excluded: do not inhale 
the product. Ammonia vapour has en irritant 
effect on mucous membranes (eyes, nose and 
throat).
keep ad blue
® out of the reach of 
children, in its original bottle.
n ever transfer ad blue
® to another 
container: it would lose its purity. Use only ad
blue
® additive that meets the 
ISO 22241 standard.
Never dilute the additive with water.
never pour the additive into the d iesel 
fuel tank.
The supply in a non-drip bottle simplifies 
toping-up. You can obtain 1.89 litre (half a 
US gallon) bottles from a CITROËN dealer or a 
qualified workshop. Never top-up from an AdBlue
® 
dispenser reserved for heavy goods 
vehicles.
Topping-up the AdBlue® additive
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 additive 
between services, more particularly if an alert 
(warning lamps and a message) signals the 
requirement.
You can got to a CITROËN dealer or a qualified 
workshop.
If you envisage topping-up yourself, please 
read the following warnings carefully.
