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

pull it out again to make the visual check:
the correct level is between the marks A
and B .
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). 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.
To ensure that the reading is correct,
your vehicle must be parked on a level

for more than 30 minutes. A = MA X

If you find that the level is above the A mark or
below the B mark, do not star t the engine .

Coolant level
Check the coolant level regularly.
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. 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.
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. When the pressure has
dropped, remove the cap and top-up the level.
Once the pressure has dropped, remove the cap
and top-up the level.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. It is normal to top-up this fluid between

Checks
12 V battery
The battery does not require any
maintenance.
However, check that the terminals
are clean and correctly tightened,
particularly in summer and winter.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 filterThe 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.
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.
When carrying out work on the battery, refer
to the "
12 V batter y " section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.

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.
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.
Electric parking brake
For more information, refer to the "Electric
parking brake - Operating faults " section.
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.
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 details of the level
checking interval for this component.
To avoid damaging the electrical units,
never use a high pressure jet wash in
the engine compartment.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

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
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. The AdBlue
® is held in a special tank with a
capacity of about 17 litres: this provides a driving
range of about 12 500 miles (20 000 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
e m pt y.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12 500 miles (20 000 km), it will be necessary
to top-up the AdBlue
®. Once the AdBlue
® tank is empty, a
s
ystem 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.

Recommendations on storage
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.
Procedure
Before topping-up, ensure that the vehicle is
parked on a flat and level sur face.
In wintry conditions, ensure that the
temperature of the vehicle is above -11°C.
Other wise, by freezing, the AdBlue
® 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.
