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:
- before a long journey,
-  at each change of season,
-  after 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.

Engine oil temperature 
gauge
Under normal operating conditions, the bars 
should be within section 1.
In severe operating conditions, the bars may 
extend into section 2 .
In this event, slow down, and if necessary, 
stop the engine and check the levels (see the 
corresponding section).
Coolant temperature gauge
Under normal operating conditions, the bars 
should be within section 1 .
In severe operating conditions, the bars may 
extend into section 2 , the engine coolant 
temperature warning lamp A and the STOP  
warning lamp come on in the instrument panel. 
Stop  as soon as it is safe to do so . Switch off 
the ignition. The cooling fan may continue to 
operate for a cer tain time .
Contact a CITROËN dealer or a qualified 
workshop.
If the SERVICE  warning lamp comes on, check 
the levels (see the corresponding section). On horizontal ground, illumination of the fuel 
low warning lamp indicates that you are at the 
reser ve level.
An alert message is displayed in the instrument 
panel.

More than 1 800 miles (3 000 km) 
remain before the next service is 
due
When the ignition is switched on, no service 
information appears in the instrument panel 
screen.
Between 600 miles (1 000 km) 
and 1 800 miles (3 000 km) remain 
before the next service is due
For a few seconds after the ignition is switched 
on, the spanner symbolising the service 
operations comes on and a message is displayed 
in the instrument panel indicating the distance or 
time remaining before the next service is due.
Example: 1 900 miles (2 800 km) remain 
before the next service is due.
When the ignition is switched on, the instrument 
panel screen temporarily indicates:
Less than 600 miles (1 000 km) 
remain before the next service is 
due
Example:  500 miles (900 km) remain before 
the next service is due.
For a few seconds after the ignition is switched 
on, the instrument panel screen indicates:
After the message disappears, the spanner 
remains on  alongside the mileage recorder as 
a reminder that a service must be carried out 
soon.
Service indicator
System which informs the driver when the 
next service is due, in accordance with the 
manufacturer's service schedule.
The point at which the service is due is 
calculated from the last service indicator reset 
to zero, according to the mileage covered and 
the time elapsed since the last service.
A few seconds after the ignition is switched on, 
the spanner goes off.
For BlueHDi Diesel versions, depending 
on the country of sale, the degree of 
deterioration of the engine oil may also 
be taken into account.

Service indicator zero resetService overdue
For a few seconds after the ignition is switched 
on, the spanner flashes to indicate that 
the service must be carried out as soon as 
possible.
Example:  the service is overdue by 180 miles 
(300 km).
When the ignition is switched on, the 
instrument panel screen indicates:
The spanner remains on  alongside the 
mileage recorder to indicate that a service is 
overdue. For b
lueHdi d iesel versions, the 
spanner may also come on early, 
according to the level of deterioration 
of the engine oil, which depends on the 
driving conditions in which the vehicle 
is used. After each service, the service indicator must 
be reset to zero.
The procedure for resetting to zero is as 
follows:
F 
switch off the ignition,
F  press and hold the trip distance recorder 
zero reset button,
F  switch on the ignition; the distance recorder 
display begins a countdown,
F  when the display indicates "=0" , release 
the button; the spanner disappears.
Following this operation, if you wish to 
disconnect the battery, lock the vehicle and 
wait at least five minutes for the zero reset to 
be taken into account.
With b
lueHdi d iesel versions, the 
Service  warning lamp also comes on 
when the ignition is switched on. The spanner may come on if you have 
exceeded the period since the last service, 
as indicated in the manufacturer's service 
schedule.

Engine oil level indicator*
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, after the servicing information.Oil level correct
This is indicated by the display of the message 
"Oil level incorrect" in the instrument panel 
screen, accompanied by the service warning 
lamp and an audible signal.
Oil level indicator fault
* Depending on version. 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.
Oil level incorrect
This is signalled by the display of the message 
"Oil level measurement invalid" in the 
instrument panel.
Contact a CITROËN dealer or a qualified 
workshop.
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.
The level read will only be correct if 
the vehicle is on level ground and the 
engine has been off for more than 
30
 minutes.

Fuel used for petrol engines
The petrol engines are compatible with 
E10 bio-petrol (containing 10 % ethanol), 
conforming to European standards EN 228 
and EN 15376.
E85 type fuels (containing up to 85 % ethanol) 
are reserved exclusively for vehicles marketed 
for the use of this type of fuel (BioFlex 
vehicles). The quality of the ethanol must 
comply with European standard EN 15293.
Fuel used for Diesel 
engines
The Diesel engines are compatible with 
biofuels which conform to current and future 
European standards (Diesel fuel which 
complies with standard EN 590 mixed with 
a biofuel which complies with standard 
EN 14214) available at the pumps (containing 
up to 7 % Fatty Acid Methyl Ester).
B30 biofuel can be used in certain Diesel 
engines. However, this use, even occasional, 
requires strict application of the special 
servicing conditions. 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).
Travelling abroad
As Diesel fuel pump nozzles may 
be different in other countries, the 
presence of the misfuel prevention 
device may make refuelling impossible.
not all d iesel vehicles are fitted with 
misfuel protection, so before travelling 
abroad, we recommend that you check 
with the CITROËN dealer network, 
whether your vehicle is suitable for the 
fuel pumps in the country in which you 
want to travel.
