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.
With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or a
qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with the regulations.
When refuelling, do not continue after the 3
rd
cut-off of the nozzle to avoid any 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.

®
When switching on the ignition, this warning
lamp flashes and the Service warning lamp
comes on, accompanied by an audible signal
and the temporary display of "NO START IN
0 km or miles" or "Top up AdBlue: Starting
impossible".
The AdBlue
® tank is empty: the starting
prevention system required by legislation
prevents starting of the engine.
To be able to restart the engine, it is
essential to add at least 5 litres of AdBlue
®
to its tank.
For more information on AdBlue
®
(BlueHDi engines) , and, in particular,
on topping up, refer to the corresponding
section.
In the event of a fault with the
SCR emissions control system
A system that prevents engine starting is
activated automatically from 685 miles
(1,100 km) after confirmation of a fault with
the SCR emissions control system.
Have the system checked by a CITROËN
dealer or a qualified workshop as soon as
possible.
In the event of the detection of a fault
If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnostic checks of the SCR
emissions control system.
These warning lamps come on, accompanied
by an audible signal and the display of the
"Emissions fault" message.
The alert is triggered while driving as soon
as the fault is detected for the first time, then
when switching on the ignition for subsequent
journeys, while the fault persists.

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

R
eplace the filter elements regularly.
We recommend the use of a combined
passenger compartment filter. Thanks to
its special active additive, it contributes
to the purification of the air breathed by
the occupants and the cleanliness of
the passenger compartment (reduction
of allergic symptoms, bad odours and
greasy deposits).
F

T
o ensure correct operation of the air
conditioning system, have it checked
according to the recommendations 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. If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a discharge of water
under the vehicle which is per fectly normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
Temporarily deactivate the Stop &
Start system to maintain a comfortable
temperature in the passenger
compartment.
For more information on Stop & Star t ,
refer to the corresponding section.
