Checking levels

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).

Engine oil level

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.

Checking using the dipstick

Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

If you find that the level is above the A

mark or

below the B

mark, do not start the engine.

If the level is above the MAX

mark (risk

of damage to the engine), contact a
CITROËN dealer or a qualified workshop.

If the level is below the MIN

mark, you

must top up the engine oil.

A = MAX

B = MIN

To ensure that the reading is correct,
your vehicle must be parked on a level
surface with the engine having been off
for more than 30 minutes.

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

The location of the dipstick is shown in the
corresponding underbonnet layout view.
F

Take the dipstick by its coloured grip and

remove it completely.

Wipe the end of the dipstick using a clean

non-fluffy cloth.

Refit the dipstick and push fully down, then

pull it out again to make the visual check:
the correct level is between the marks A
and B

Oil grade

Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.

210

Practical information

B618_en_Chap07_info-pratiques_ed01-2016

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.

Topping up the engine oil level

The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F Unscrew the oil filler cap to reveal the filler

aperture.

Add oil in small quantities, avoiding any

spills on engine components (risk of fire).

Wait a few minutes before checking the

level again using the dipstick.

Add more oil if necessary.

After checking the level, carefully refit the

oil filler cap and the dipstick in its tube.

Engine oil change

Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.

The brake fluid level should be close
to the "MAX" mark. If it is not, check
the brake pad wear.

Brake fluid level

Changing the fluid

Refer to the manufacturer's service schedule
for details of the interval for this operation.

Fluid specification

The brake fluid must conform to the
manufacturer's recommendations.

211

Practical information

B618_en_Chap07_info-pratiques_ed01-2016

Coolant level

Check the coolant level regularly.
It is normal to top up this fluid
between services.

When the engine is hot, the temperature of the
coolant is regulated by the fan.

The coolant level 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.
A low coolant level presents a risk of serious
damage to your engine.

Fluid specification

The coolant must conform to the
manufacturer's recommendations.

Fluid specification

For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.

Screenwash fluid level

Top up the level when necessary.

The cooling fan may start after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.

When the engine is hot, 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 in the event of an
urgent need to top up, with a cloth around the
cap, unscrew it by two turns to allow the pressure
to drop.
Once the pressure has dropped, remove the cap
and top up the level.

To ensure that the measurement is reliable, the
vehicle must be parked on level ground and the
engine must be cold.

Topping up

The reservoir must be topped up without delay
by a CITROËN dealer or a qualified workshop.

Diesel fuel additive level
(Diesel with particle filter)

The additive reservoir 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.

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.

Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.

Used products

AdBlue level

An alert is triggered when the reserve level is
reached.
To avoid statutory immobilisation of the vehicle,
the AdBlue must be topped up.

Checking components

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.

Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.

Air filter and passenger compartment filter

Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.

Oil filter

Unless otherwise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Otherwise, have them checked by a CITROËN dealer or a qualified workshop.

Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary

A clogged passenger compartment filter may
have an adverse effect on the performance
of the air conditioning system and generate
undesirable odours.

Particle filter (Diesel)

The start of saturation of the particle

filter is indicated by the fixed

illumination of this warning lamp

accompanied by a warning message.

As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates a
low additive level.
For more information on Checking levels and
the Diesel additive level in particular, refer to
the corresponding section.

On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is perfectly 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.

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.

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

Brake pads

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.

Brake disc wear

Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units 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.

Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

Automatic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.

Checking this system must be done by a
CITROËN dealer or a qualified workshop.

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.

AdBlue

and SCR system

for BlueHDi Diesel engines

To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
performance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.

SCR system

Using a fluid called AdBlue

containing urea, a

catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.

Once the AdBlue

tank is empty, a

system required 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 650 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.

The AdBlue

is held in a special tank with

a capacity of about 15 litres: this provides
a driving range of about 11 000 miles
(18 000 km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2 400 km) before the tank is empty.

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 all weather
conditions.

216

Practical information

B618_en_Chap07_info-pratiques_ed01-2016

Precautions in use

Keep AdBlue

out of the reach of

children, in its original container or
bottle.
Never transfer AdBlue

to another

container: it would lose its purity.

Never dilute AdBlue

with water.

Never pour AdBlue

into the Diesel fuel

tank.

Never top up from an AdBlue

dispenser reserved for heavy goods
vehicles.

Use only AdBlue

fluid that meets the

ISO 22241 standard.

The supply in a non-drip container or bottle
simplifies topping up. You can obtain 1.89 litre
(half a US gallon) bottles or 5 or 10 litre
containers from a CITROËN dealer or a
qualified workshop.

AdBlue

is a urea-based solution. This liquid is

non-flammable, colourless and odourless (kept
in a cool area).
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,
wash (irrigate) the eyes with large amounts of
water or with an eye wash solution for at least
15 minutes. If a burning sensation or irritation
persists, get medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high exterior temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the fluid.
Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat).

Topping up the AdBlue

217

Practical information

B618_en_Chap07_info-pratiques_ed01-2016

Recommendations on storage

or
F

With Keyless Entry and Starting, press the

"START/STOP" button to switch off the
engine.

AdBlue

freezes at about -11°C and

deteriorates above 25°C. It is recommended
that bottles 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 additive has frozen, it can be used once it
has completely thawed out.

Before topping up, 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

so 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.

Open the filler

With the vehicle unlocked, open the fuel

filler flap; the blue filler cap for the AdBlue

tank is located to the right of the black fuel
filler cap.

Turn the blue cap a quarter of a turn anti-

clockwise.

Remove the blue cap.

Do not dispose of AdBlue

bottles or

containers in the household waste.
Place them in a container provided for
this purpose or take them to your dealer.

Top up

F Obtain a bottle of AdBlue

. After first

checking the use-by date, read carefully
the instructions on use on the label before
pouring the contents of the bottle into your
vehicle's AdBlue

tank.

Important

: if your vehicle's AdBlue

tank is completely empty - which is
confirmed by the alert messages and
the impossibility of starting the engine -
you must add at least 4 litres and no
more than 10 litres.

If any fluid is spilt or splashed, wash
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: when topping up after
running out of AdBlue

, signalled

by the message "Top up AdBlue:
starting impossible

", you must wait for

about 5 minutes before switching the
ignition on again, without opening the
driver's door, unlocking the vehicle,
introducing the remote control key
into the ignition switch, or placing
the Keyless Entry and Starting
electronic key inside the vehicle.
Switch on the ignition, then wait for
10 seconds before starting the engine.

After emptying the bottle, wipe away any

spillage around the tank filler using a damp
cloth.

Refit the filler cap

Refit the blue cap and turn it a quarter of a

turn clockwise, to its stop.

Close the filler flap.
