Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6
miles (10 km)
at moderate speeds).
Other wise, add 0.3
bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This warning is indicated by
continuous illumination of this
warning lamp, an audible signal
and, depending on equipment, a
message displayed on the screen.
F

R

educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S

top the vehicle as soon as it is safe to do
so. The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check.
F
I
f you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold.
F
I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
I
n case of a puncture, use the temporary
tyre repair kit or the spare wheel (depending
on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels. Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
The system must be reinitialised with the
ignition on and the vehicle stationary:
-

I f you have put the wrong fuel in your
vehicle, you must have the fuel tank
drained and filled with the correct fuel
before star ting the engine.
Low fuel level
When the low fuel level in the
tank is reached, this warning lamp
comes on in the instrument panel,
accompanied by an audible warning
and a message.
When it first comes on, about 5


litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied
by a message and an audible signal, until
a sufficient addition of fuel is made. This
audible signal and message are repeated with
increasing frequency as the fuel level drops
and approaches " 0".
Refuel as soon as possible to avoid running
out.

fuel (Diesel) , refer to the corresponding
section.
Refilling
A self-adhesive label on the inner face of the
filler flap reminds you of the type of fuel to use,
depending on your engine.
Additions of fuel must be of at least 5
litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise
caused by an inrush of air. This vacuum is

When the engine is warm, the temperature of
the coolant 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 when you need to
top up in an emergency, place 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 the coolant.The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
A low coolant level presents a risk of serious
damage to your engine.
Top up the fluid when necessary.Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel fuel additive level
(Diesel with particle filter)
The additive tank minimum level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue
® and the SCR
system, and, in particular, topping it up, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
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.
Practical information

179
For more information on the precautions
to take before starting work on the 12 V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a 12
V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary .
Passenger compartment filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary. A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the constant
illumination of this warning lamp
accompanied by an alert message.
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
and particularly on the level of Diesel
additive, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).

Practical information

181
During each scheduled ser vice of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two ser vices is greater than around
12,000

miles (20,000 km), it will be necessary
to top up the AdBlue
®.
Once the AdBlue
® tank is empty, a system
r
equired by regulations prevents starting
of the engine.
If the SCR

system is faulty, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the
SCR system, you must go to a CITROËN
dealer or a qualified workshop as soon
as possible: after a running distance of
680

miles (1,100

km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, refer to the corresponding section. Freezing of 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 all weather conditions.
Topping up with AdBlue®
Before topping up, please read the
following warnings carefully.
Precautions for use
The AdBlue® solution is based on urea. This
liquid 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 water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15
minutes. If you feel
a persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water. Keep AdBlue
® out of the reach of children,
in its original container.
Never transfer AdBlue
® to another
container: it would become contaminated.
Use only AdBlue
® fluid that meets the
ISO
22241 standard.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
Containers are available from a
CITROËN

dealer or a qualified workshop.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
You can also visit a ser vice station
equipped with AdBlue pumps specially
designed for private vehicles and light
goods vehicles.
