only by a
CITROËN dealer or a qualified
workshop.
Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a
level drops significantly, have the
corresponding system checked by a
CITROËN
dealer or a
qualified workshop.
The liquid must comply with the
manufacturer's recommendations and with
the vehicle's engine. 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

fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not
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).
Checking using the dipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.

F

R
efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between marks A and B .A = MA X
B = MIN
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Practical information

201
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.

Practical information

202
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

203
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
specific check. However, in the
event of a problem, have the system
checked by a
CITROËN dealer or
a


qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey. The pressures given 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 more than 31 mph (50 km/h),
0.3 bar (30 kPa) should be added to the values
given on the label.
Under-inflation increases fuel consumption.
Non-compliant tyre pressure causes premature
wear on tyres and has an adverse effect on the
vehicle's road holding – Risk of an accident!
Driving with worn or damaged tyres reduces
braking efficiency and control of the vehicle's
steering. Regular inspections of the condition
of tyres (tread and sides) and rims are
recommended as well as making sure that
valves are fitted.
Using different size wheels and tyres from
those specified can affect the lifetime of tyres,
wheel rotation, ground clearance and the
speedometer reading and have an adverse
effect on road holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
7
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

205
Topping up the AdBlue®
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
services, more particularly if an alert (warning
lamps and a


message) signals the requirement.
You can go to a

CITROËN dealer or a qualified
workshop.
If you envisage topping up yourself, please
read the following warnings carefully.
Supply of AdBlue®
It is recommended that the AdBlue® is
topped up as soon as the first alert is
issued indicating that the reser ve level has
been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® liquid that meets the
ISO
22241
standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water. You can obtain AdBlue
® from a CITROËN
d
ealer or a

qualified workshop.
You can also visit a
petrol station
equipped with AdBlue
® pumps specially
designed for passenger vehicles (for those
versions with access to the AdBlue
® tank
via the fuel filler flap).
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Recommendations on
storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never keep containers or bottles of
AdBlue
® in your vehicle.
Precautions for use
AdBlue® is a urea-based solution. 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.
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).
Keep AdBlue
® out of the reach of children,
in its original container or bottle.
Procedure
Before starting the top-up procedure, ensure
that the vehicle is parked on a flat and level
sur face.
7
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
