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...). Use a roof box in preference.
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.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter, 
passenger compartment filter...) and observe the schedule of 
operations recommended in the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system is faulty your vehicle 
becomes polluting; go to a CITROËN dealer or a qualified workshop 
without delay to have the emissions of nitrous oxides brought back to 
the legal level.
When refuelling, do not continue after the third cut-off of the nozzle to 
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles 
(3
  000 kilometres) that you will see the fuel consumption settle down to 
a consistent average.

On versions fitted with an electric oil level 
indicator, the state of the engine oil level is 
displayed in the instrument panel for a few 
seconds, at the same time as the servicing 
information.
Engine oil level indicator*
The level read will only be correct if 
the vehicle is on level ground and the 
engine has been off for more than 
30
 m
inutes.
Oil level correct
Oil level incorrect
This is indicated by the flashing of " OIL" or the 
display of a message, accompanied by the 
service warning lamp and an audible signal.
If the low oil level is confirmed by a check using 
the dipstick, the level must be topped up to 
avoid damage to the engine.
Refer to the "Checking levels" section.
Oil level indicator fault
This is signalled by the flashing of " OIL- -" or 
the display of a message.
Contact a CITROËN dealer or a qualified 
workshop.
In the event of a fault with the electric indicator, 
the oil level is no longer monitored.
If the system is faulty, you must check the 
engine oil level using the manual dipstick 
located under the bonnet.
Refer to the "Checking levels" section.
* Depending on version.

Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, 
the interior temperature is very 
high, first ventilate 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 air conditioning system does not 
contain chlorine and does not present 
any danger to the ozone layer.
In order for these systems to be fully effective, follow the operation and maintenance 
guidelines below:
F
 
T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles 
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well 
as the air extractor located in the boot.
F
 
D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation 
of the 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 have the filter 
elements replaced regularly.
 W
e 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, 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. The condensation created by the air 
conditioning results in a discharge 
of water under the vehicle which is 
per fectly normal.
Stop & Start
The heating and air conditioning systems only work when the engine is running. To maintain 
a comfortable temperature in the passenger compartment, you can temporarily deactivate 
the Stop & Start system (see the corresponding section).

Windscreen and headlamp wash
Windscreen wash
F Pull the windscreen wiper stalk towards you. The windscreen wash then the 
windscreen wipers operate for a fixed 
period.
It operates only when the headlamps are off or 
the vehicle is stationary.
Low screenwash / headlamp 
wash fluid level
On vehicle fitted with headlamp washers, the 
low level of this fluid is indicated by gauge in 
the reservoir filler neck under the bonnet.
Checking and topping up this fluid can should 
be done with the engine off.
The level of this fluid should be 
checked regularly, particularly during 
w i n t e r.
Refer to the "Checks - Screenwash / headlamp 
wash level" section for the procedure on 
checking the level.
Headlamp wash
Associated with the windscreen wash, the 
headlamp washers operate with the vehicle 
moving, when the dipped or main beam 
headlamps are on .
To reduce the consumption of the fluid 
by the headlamp washers, they operate 
only with every seventh use of the 
screenwash or every 25 miles (40 km) 
during a given journey.
