AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and, in particular, topping it up, refer to
the corresponding section.
Checks
Unless otherwise 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.
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.
For more information on 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.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary
.
Passenger compartment
filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it 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.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the constant
illumination of this warning lamp
accompanied by an alert message.

Practical information

148
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37 mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking the
levels and particularly on the level of
Diesel additive, 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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
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.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Brake disc/drum wear
For information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
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.
Practical information

AdBlue® (BlueHDi
engines)
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. The AdBlue
® is contained in a
special tank holding about
17 litres.
An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a further 1,500 miles (2,400 km) before the
tank is empty.
If the estimated distance travelled by your
vehicle between two ser vices 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 system
r
equired 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 travelling the distance of
685 miles (1,100 km), a system preventing
the engine starting will be triggered
automatically.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised. For more information on the Warning
and indicator lamps
and the associated
alerts, refer to the corresponding section.
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 very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be
topped up as soon as the first alert is
issued indicating that the reser ve level has
been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® liquid that meets the
ISO 22241 standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that combines SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.
