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 other wise 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 star t the engine.
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top up the engine oil.
A = MA X
B = MIN
To ensure that the reading is correct,
your vehicle must be parked on a level
sur face 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

T
ake the dipstick by its coloured grip and
remove it completely.
F

W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R
efit 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.
Practical information

205
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.

fter 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 "MA X" 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.

To p p i n g u p
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.
For more information on AdBlue and the SCR
system, and in particular topping up, refer to
the corresponding section.

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 other wise 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.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 per formance
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 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.
For more information and the precautions to
take before starting work on the 12 V batter y
,
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.

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
per formance 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.

high visibility vest.Refer to the instructions provided with the
triangle.
Positioning the triangle
Running out of fuel
(Diesel)
On vehicles fitted with Diesel engines, the fuel
system must be primed if you run out of fuel. For more information on Misfuel
prevention (Diesel) , refer to the
corresponding section.

Composition of the kit
The speed limit sticker must be secured
to the interior of the vehicle in the
driver's field of vision, to remind you
that a wheel is in temporary use.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair.
This kit is installed in the storage box, under the
boot floor.
Comprising a compressor and a sealant
cartridge, it allows the temporary repair
of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
Temporary puncture repair kit
Access to the kit
Do not exceed a speed of 50 mph
(80 km/h) when driving with a tyre
repaired using this type of kit.
