Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items at the back 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.
Obser ve 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. Visit a CITROËN dealer or
a

qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with regulations.

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 switching the ignition on, after
the ser vicing information, in the form of
messages. 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.
Low oil level
This is indicated by the display of a message
p rompting you to top up, 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.

Malfunction of the SCR
emissions control system
Malfunction detection
If a malfunction is detected,
t hese warning lamps come on,
accompanied by an audible signal
and the display of an "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. If it is a
temporary fault, the alert
disappears during the next journey,
after self-diagnostic checks of the SCR
emissions control system.
Malfunction confirmed during the
permitted driving phase (between
685
miles and 0 miles (1,100 km and 0 km))
If the warning lamp is still on after 31 miles
( 50 km) of driving, the fault in the SCR system
is confirmed. Have the system checked by a
CITROËN
dealer or a qualified workshop as soon as
possible.
Starting prevented
Every time the ignition is switched on, the
message "Emissions fault: Starting prevented"
is displayed.
To be able to restart the engine, call
on a
CITROËN dealer or a qualified
workshop.
The AdBlue warning lamp flashes,
accompanied by the display of a
message
("Emissions fault: Starting prevented in x
miles") indicating the remaining range in miles
or kilometres.
While driving, the message is displayed every
30

seconds. The alert is repeated when
switching on the ignition.
You can continue driving for up to 685 miles
(1,100 km) before the engine star ting
prevention system is triggered.

It remains possible to use a fuel can to fill
t he tank.
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 Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with a
CITROËN dealer whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
When a
petrol filler nozzle is introduced into
the fuel filler neck of a 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.
Compatibility of fuels
The use of any other type of (bio) fuel
(vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.
Diesel fuels conforming to the EN590,
EN16734 and EN16709 standards respectively
and containing up to 7%, 10%, 20% and 30%
fatty acid methyl ester respectively. The use of
B20
or B30 fuels, even occasionally, imposes
special maintenance conditions referred to as
"Arduous conditions".
Paraffinic Diesel fuel conforming to the
EN15940

standard.
Diesel at low temperature
At temperatures below 0°C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50% full.
At temperatures below -15°C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Cer tain fuels could damage your vehicle's
engine.
In cer tain countries, the use of a
par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For all additional information, consult a


dealer.

-
B
elow mark B
, then top up the engine oil
immediately.
Take care when working under the bonnet,
as certain areas of the engine may be
extremely hot (risk of burns) and the
cooling fan could start at any time (even
with the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health,
and may be very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers
reser ved for this purpose at a
CITROËN
dealer or a
qualified workshop.
Engine oil
The level is checked either using the
oil level indicator in the instrument
panel when the ignition is switched
on, for vehicles equipped with an
electric gauge, or using the dipstick.
The vehicle must be parked on a level sur face,
w ith the engine stopped for more than 30 minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). It is recommended
that you check the level, and top up if
necessary, every 3,000
miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close
to the " MAX" mark. If not, check the
brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Engine coolant
Check the engine coolant level
regularly.
It is normal to top up this fluid
between two services. The check and top-up must only be done with
the engine cold.
A low level presents a
risk of serious damage
to the engine.
The level of this fluid should be close to the
" MAX " mark but should never exceed it.
If the level is close to or below the " MIN" mark,
it is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid the risk of scalding if you need to top
up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow
the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
