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.

Stop & Start
The Stop & Start system puts the engine
temporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams, etc.).
The engine restarts automatically – START
mode – as soon as you wish to move off.
Restart is instantaneous, quick and silent.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions and offers the comfort of complete
silence when stationary.
Going into engine STOP
mode
With the vehicle stationary, put the gear lever
into neutral, then release the clutch pedal.This indicator lamp comes on in the
instrument panel and the engine
goes into standby.
Automatic stopping of the engine is only
possible after the vehicle has exceeded
a
speed of about 6 mph (10 km/h), to avoid
repeated stopping of the engine when
driving slowly. Never leave your vehicle before turning off
the ignition with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not triggered when:
-
t he system is initialising,
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he air conditioning is on,
-

t
he rear screen demisting is on,
-

t
he windscreen wipers are on fast wipe,
-

r
everse gear is engaged for a parking
manoeuvre,
-
s

ome special conditions (battery charge,
engine temperature, particle filter
regeneration, braking assistance, exterior
temperature, etc.) where the engine is
needed to assure control of a
system.-

d
uring intensive use of Stop & Start, it
may be deactivated to conser ve starting
ability; go to a CITROËN dealer to have the
function reactivated.
This indicator lamp in the instrument
panel flashes for a few seconds,
then goes off.
This operation is perfectly normal.
Going into engine START
mode
With the vehicle in gear, automatic engine
restarting is only allowed by fully depressing
the clutch pedal.
This indicator lamp goes off and the
engine restarts.
If the driver takes no action on the vehicle for
3
minutes after an automatic restart in START
mode, the system stops the engine definitively.
The engine can then only be restarted using
t h e key.

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
(the maximum consumption is

disc wear, contact a CITROËN or
a


qualified workshop.
Parking brake
If excessive travel or a loss of
e ffectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a
CITROËN
dealer or a
qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reser voir. If this warning lamp comes on, the
filter must be purged to remove
water.
You can also purge the fuel filter
regularly, every time the engine oil
is changed.
Purging water from the filterThe HDi engines use advanced technology.
All work must be done by personnel that
have had special training, which can be
ensured by going to a
CITROËN dealer or
a


qualified workshop.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.

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.
