Checking levels

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.

Engine oil level

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.

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).

A = MAX

B = MIN

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.

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.

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).

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.

Locate the dipstick in the engine

compartment of your vehicle.

For more information on the petrol or Diesel
engine, refer to the corresponding section.
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

Topping-up the engine oil level

Locate the oil filler cap in the engine

compartment of your vehicle.

For more information on the petrol or Diesel
engine, refer to the corresponding section.
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.

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

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.

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.

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

Power steering
fluid level

The power steering fluid level should
be close to the "MAX" mark. With
the engine cold, unscrew the cap to
check the level.

Screenwash / headlamp
wash fluid level

Specification of the fluid

To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of a fluid
with an ethyl alcohol or methanol base is
recommended.

To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.

F Open the bonnet and secure it with the

stay.

Open the screenwash reservoir filler cap.

Take and pinch the level gauge to block its

breather.

Remove the gauge completely from

the reservoir to read the level in the
transparent section.

Coolant level

The coolant level should be close
to the "MAX" mark but should never
exceed it.

Fluid specification

The coolant must conform to the
manufacturer's recommendations.

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 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 any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.

Top up if necessary.

blockage of the particle filter.

The presence of this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop
is essential when replacing or disconnecting
the battery.

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, refer to the
"Additive level" section.

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.

and correctly tightened, particularly in summer
and winter.

When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.

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.

The start of saturation of the particle filter is
indicated by:

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

AdBlue

additive 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.

Presentation of the SCR system

Using an additive called AdBlue

containing urea,

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

The AdBlue

additive is held in a special

tank located under the boot at the rear of
the vehicle. It has a capacity of 17 litres: this
provides a driving range of about 12 500 miles
(20 000 km), after which an alert is triggered
warning you when the reserve remaining is
enough for just 1 500 miles (2 400 km).

During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue

additive tank is refilled in order to

allow normal operation of the SCR system.

If the estimated mileage between two services
is greater than 12 500 miles (20 000 km), we
recommend that you go to a CITROËN dealer
or a qualified workshop to have the necessary
top-up carried out.

Once the AdBlue

tank is empty, a

system required by regulations prevents
starting of the engine.
If the SCR 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.

Freezing of the AdBlue

additive

The AdBlue

additive 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.

Topping-up the AdBlue

additive

Precautions in use

Use only AdBlue

additive that meets

the ISO 22241 standard.

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

Keep AdBlue

out of the reach of

children, in its original bottle.
Never transfer AdBlue

to another

container: it would lose its purity.

Never dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.

Never top-up from an AdBlue

dispenser reserved for heavy goods
vehicles.

Filling the AdBlue

tank is an operation

included in every routine service 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 additive
between services, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can got to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.

The AdBlue

additive is an 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 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 ambient
temperature, for example), the risk of release
of ammonia cannot be excluded: do not inhale
the product. Ammonia vapour has en irritant
effect on mucous membranes (eyes, nose and
throat).

Recommendations on storage

Procedure

Switch off the ignition and remove the

key, or if your vehicle has one, press the
START/STOP button to switch off the
engine.

F Raise the boot floor for access to the

AdBlue

tank.

Secure the boot floor by attaching its cord
to the hook on the parcel shelf support.

Unclip the black plastic blanking plug using

its tab.

Insert your fingers into the aperture and

turn the blue cap a 6

of a turn anti-

clockwise.

Carefully lift off the cap, without dropping it.

Never store bottles of AdBlue

in your

vehicle.

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.

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 additive can be
kept for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.

Practical information

235

C4-2_en_Chap07_infos-pratiques_ed02-2015

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.

After emptying the bottle, wipe away any

spillage around the tank filler using a damp
cloth.

Refit the blue cap to the tank and turn it a

of a turn clockwise, to its stop.

Refit the black plastic blanking plug,

clipping it in on the flap

Detach the cord from the parcel shelf

support and lower the boot floor.

Important: if your vehicle's AdBlue

tank is completely empty - which is
confirmed by the alert displays and the
impossibility of starting the engine - you
must add at least 3.8 litres
(so two 1.89 litre bottles).

If any additive is split or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the additive 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 additive

, 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
"Keyless Entry and Starting" system
into the passenger compartment

Switch on the ignition, then, after
10 seconds, start the engine.

Never dispose of AdBlue

additive

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