Practical information
7Recommendations
► Distribute the load uniformly , taking
care to avoid overloading one of the sides.
►

Arrange the heaviest part of the load as
close as possible to the roof.
►


Lash the load down securely and fit a
warning flag if it overhangs the vehicle.
►


Drive gently: the vehicle will be more
susceptible to the effects of side winds
(stability may be affected).
►


Remove the roof bars once they are no
longer needed.
Maximum load, distributed over the roof
bars, for a loading height not exceeding
40 cm: 80 kg.
As this value may change, please verify the
maximum load quoted on the note supplied
with the roof bars.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the profile of the road
to avoid damaging the roof bars and the
mountings on the vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects which are longer than the vehicle.
Bonnet
Stop & Start
Before doing anything under the bonnet,
you must switch off the ignition to avoid any
risk of injury resulting from an automatic
change to START mode.
The location of the interior bonnet release lever prevents opening the
bonnet when the left-hand front door is
closed.
When the engine is hot, handle the
exterior safety catch and the bonnet stay
with care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.

Practical information
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, 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.
It is normal to top up the oil level between two
services (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.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and

oil is changed.
Particle filter (Diesel)
The start of saturation of the particle filter
is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
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.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order 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.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the

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.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.

Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust on
acceleration. This does not affect the
behaviour of the vehicle or the environment.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc/drum wear
For any information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness 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.
Wheels and tyres
The pressure must be checked on all tyres, including the spare wheel, when the
tyres are "cold".
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Driving with under-inflated tyres
increases fuel consumption. Non-
compliant tyre pressure causes premature
wear on tyres and has an adverse effect on

Practical information
Storage recommendations
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out in the ambient air.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept 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. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store AdBlue® out of the reach of
children, in its original container.
the vehicle's road holding - risk of an
accident! Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.

Using different size wheels and tyres from those
specifi ed can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse e

ffect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
AdBlue ®
(BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its 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 ®
that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 5,600
miles (9,000 km), which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400
km) before the tank is
empty and the vehicle blocked.
If the estimated distance travelled by the vehicle
between two services is greater than 12,500
miles (20,000 km), it will be necessary to top up
the AdBlue.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a
system required by legislation prevents
starting of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 680
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
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.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–
Use only AdBlue® fluid that meets the ISO
22241 standard.
–
Never transfer

AdBlue
® to another container
as it would lose its purity.
–
Never dilute AdBlue® with water.
It is possible to obtain AdBlue
® from a CITROËN
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles.
Never top up from an AdBlue® dispenser
reserved for heavy goods vehicles.

Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11
°C. Otherwise, the
AdBlue
® may be frozen and therefore cannot
be poured into its tank. Park your vehicle in a
warmer area for a few hours to allow the top-up
to be carried out.
Never pour AdBlue® into the Diesel fuel
tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off using a
sponge and hot water.
Important: in the event of a top-up after
a breakdown because of a lack of
AdBlue, it is essential to wait around 5
minutes before switching on the ignition,
without opening the driver’s door,
unlocking the vehicle, introducing the key
into the ignition switch, or introducing the
key of the “Keyless Entry and Starting

”
system into the passenger compartment

.
Switch on the ignition, then wait for 10
seconds before starting the engine.
► Switch off the ignition and remove the key
from the switch to switch off the engine.

AdBlue
®: after
checking the expiry date, read the instructions
on the label carefully before pouring the contents
into the vehicle's AdBlue tank.
►

With an


AdBlue® pump: introduce the nozzle
and fill the tank until the nozzle automatically
cuts out.
In order not to overfill the AdBlue® tank:
–
Add between 10 and 13 litres using
AdBlue® containers.
–
Stop after the nozzle’ s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
® top-ups of
5

litres or more.

Practical information
For the care of the stickers in the rear
door windows (quarter panels), we
recommend the following:
– Use a wide jet at a temperature of between
25°C and 40°C.
– Where possible, direct the jet at right
angles to the stickers."Top up AdBlue: Starting impossible" – it is
essential to add at least 5 litres.
After refilling
► Refit the blue cap to the tank filler and turn it
clockwise, as far as it will go.
►

Close the fuel filler flap.
Do not dispose of AdBlue® bottles or
containers in the household waste.

Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging your vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment, due to the risk
of damaging electrical components.
Do not wash the vehicle in strong sunshine or
extremely cold conditions.
When washing the vehicle at an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
remove the electronic key.
When using a pressure washer, hold the
lance at least 30 cm from the vehicle
(particularly when cleaning areas containing
chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's paint
(including tree resin, bird droppings, insect
secretions, pollen and tar).
If justified by the environment, clean the
vehicle more frequently to remove salty
deposits (in coastal areas), soot (in industrial
estates) and mud (in wet or cold areas).
These substances can be highly corrosive.
Contact a CITROËN dealer or a qualified
workshop if you require advice on removing
stubborn stains requiring special products
(such as tar or insect removers).
Preferably, have paint touch-ups performed
by a CITROËN dealer or a qualified
workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure washer to
clean the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage if they come into contact with the
controls in the dashboard and centre console.
Take care!
Bodywork
High-gloss paint
Do not use abrasive products or
solvents, petrol or oil to clean the
bodywork.
Never use an abrasive sponge to clean
stubborn stains. Risk of scratching the
paintwork!
Do not apply polish in strong sunshine, or to
plastic or rubber parts.
Use a soft sponge and soapy water or a
pH neutral product.
Gently wipe the bodywork with a clean
microfibre cloth.
Apply polish with the vehicle clean and dry.
Comply with the instructions for use stated on
the product.
Care of the stickers
These styling stickers are treated to give good
resistance to ageing and tearing.
They have been designed to allow you to
customise your vehicle's bodywork.
When washing your vehicle, keep the high-
pressure lance tip at least 30 cm away from the
stickers.

107
Practical information
7For the care of the stickers in the rear
door windows (quarter panels), we
recommend the following:
–

Use a wide jet at a temperature of between
25°C and 40°C.
–


Where possible, direct the jet at right
angles to the stickers.
