valid during the 30
minutes after topping
up.
Engine oil change
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3,000
miles (5,000 km).

Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up. To avoid the risk of scalding when 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.
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
This fluid must conform to the manufacturer's
recommendations.
Screenwash/headlamp
wash level low
In the case of vehicles fitted with
headlamp washers, when the fluid
reser voir low level is reached this
warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a


message.
The warning lamp comes on when the ignition
is switched on, or every time the stalk is
operated, until the reser voir is refilled.
The next time you stop, have the screenwash/
headlamp wash reser voir topped up.
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low 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
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Level of AdBlue
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 up the tank,
refer to the corresponding section.
When the engine is hot, 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.

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.
For more information and 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
Change the oil filter each time the
engine 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.
Traffic conditions permitting, 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.
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.
Practical information

204
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.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
AdBlue® (BlueHDi engines)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of 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 fluid called AdBlue® that contains
urea, a catalytic converter turns up to 85%
of 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 around
12,500

miles (20,000

km). An alert system is
triggered automatically once the reser ve level
is reached: you can then drive for a
further
1,500

miles (2,400

km) before the tank is
e m pt y. Once the AdBlue
® tank is empty, a system
required by regulations prevents starting
of the engine.
If the SCR system is defective, 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
685

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 associated alerts,
refer to the corresponding section.
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.
Practical information

206
In winter, check that the temperature of the
vehicle is above -11°C. If not, due to freezing,
the AdBlue
® cannot be poured into the tank.
Park your vehicle somewhere warmer for a few
hours before topping up.
In the event of an AdBlue
® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5

litres.
Never pour AdBlue
® into the Diesel fuel
tank.
If any AdBlue
® is splashed, or if there are
any spillages on the side of the body, 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, you must wait around 5
minutes
before switching on the ignition, without
opening the driver's door, locking the
vehicle, introducing the key into the
ignition switch, or introducing the key of
the

K
eyless Entr y and Star ting system
into the passenger compartment .
Switch on the ignition, then wait for
10


seconds before starting the engine.
Access to the AdBlue® tank via
the boot
Filling the AdBlue® tank is an operation
included in every routine ser vice on your
vehicle by a

CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top up the fluid between
ser vices, as soon as an alert (warning lamps
and a

message) indicates it.
You can go to a

CITROËN dealer or a qualified
workshop.
If you intend to do the topping-up yourself,
read the following procedure carefully.
