staff, which only a CITROËN dealer can provide.
checks

247
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.
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). 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.
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.checking using the

coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.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.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
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.
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 an ethyl alcohol
or methanol base fluid is recommended.

checks

251
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
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.
Checks
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals are
correctly tightened and that the connections
are clean.
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.
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.
When carrying out any operation on the 12 V
battery, refer to the corresponding section for
details of the precautions to be taken before
starting work.
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 filterParticle filter (
di
esel)
The start of saturation of the particle
filter is indicated by the temporary
illumination of this warning lamp
accompanied by a message in the
multifunction screen.
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,
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.

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.
Presentation of the ScR s ystem
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 s
ystem 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.
checks

255
When switching on the ignition, the
UREA warning lamp comes on, accompanied
by an audible signal and the display of a
message (e.g.: "Top up emissions additive:
Starting prevented in 900 miles") indicating
the remaining range expressed in miles or
kilometres.
When driving, the message is displayed every
200 miles (300 km) until the additive tank has
been topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
For more information on topping-up the
AdBlue
® additive, refer to the corresponding
section.
Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of a message (e.g. "Top
up emissions additive: Starting prevented in
350 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
30 seconds until the additive tank has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine.
Remaining range between 0 and 350 miles (0 and 600 km)
When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of the message "Top up
emissions additive: Starting prevented".
The AdBlue
® tank is empty: the system required
by regulations prevents engine starting.
Breakdown related to a lack of AdBlue® additive
To be able to start the engine,
we recommend that you call on
a CITROËN dealer or a qualified
workshop for the top-up required.
If you carry out the top-up yourself, it
is essential to add at least 3.8 litres of
AdBlue
® to the tank.
For more information on topping-up the
AdBlue
® additive, refer to the corresponding
section.
checks

If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
A system that prevents engine
starting is activated automatically
from 650

miles (1 100 km) after
confirmation of a fault with the SCR
emissions control system. Have the
system checked by a CITROËN dealer
or a qualified workshop as soon as
possible. The UREA, SERVICE and diagnostic warning
lamps comes on, accompanied by an audible
signal and the display of the message
"Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists. In the event of the detection of a fault
If a fault with the SCR system is confirmed
(after 30 miles (50 km) covered with the
permanent display of the message signalling
a fault), the SERVICE and engine diagnostic
warning lamps come on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of a message
(e.g.: "Emissions fault: Starting prevented in
150 miles") indicating the remaining range
express in miles or kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the
ignition.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
Other wise, you will not be able to restart your
engine.
