Practical information
AdBlue (BlueHDi)
12 V battery
A clogged cabin filter may have an
adverse effect on the performance of
the air conditioning system and generate
undesirable odours.
An alert is triggered once the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised as per
regulations, you must top up the AdBlue tank.
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.
Air filter
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessary.
For more information on the precautions to
take before any work on the 12 V battery,
refer to the corresponding section.
For more information on the Supply of
AdBlue, 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.
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.
Oil filter
Change the oil filter each time the
engine oil is changed.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Particle filter (Diesel)
The start of saturation of the particle
filter is signalled by the temporary
illumination of this warning lamp,
accompanied by a message warning
of the risk of the filter clogging up.
Cabin filter
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessary.
or
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.

Practical information
Brake pads
Electric parking brake
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
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.
This system does not require any
routine servicing. However, in case
of an issue, do not hesitate to have
the system checked by a CITROËN
dealer or a qualified workshop.
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.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
For more information on the Electric
parking brake, refer to the corresponding
section.
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
Wheels and tyres
New vehicle
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a month and before a long
journey.
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is perfectly normal.
applications to dry and defrost the brakes.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have
driven for more than 10 minutes or more
than 6 miles (10 kilometres) at over 31 mph
(50 km/h), add 0.3 bar (30 kPa) to the values
indicated on the label.
Manual gearbox

Brake disc wear
The gearbox does not require any
maintenance (no oil change).
For information on checking brake
disc wear, contact a CITROËN
dealer or a qualified workshop.
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

Practical information
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.
Headlamps and lamps
Driving with under-inflated tyres increases
fuel consumption. Non-compliant tyre
pressure causes premature wear on tyres
and has an adverse effect on the vehicle's
road holding – risk of an accident!
The headlamps have polycarbonate
lenses with a protective coating.
Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
Use a sponge and soapy water.
The use of a high pressure jet wash for
cleaning the headlamps, lamps and their
surrounds may damage the lacquer and
seals.
Driving with worn or damaged tyres reduces
the braking and road holding performance of
the vehicle. It is recommended to regularly
check the condition of the tyres (tread and
sidewalls) and wheel rims as well as the
presence of the valves.
Using different size wheels and tyres from
those specified can affect the lifetime of
tyres, wheel rotation, ground clearance, the
speedometer reading and have an adverse
effect on road holding.
SCR system
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a sponge
and warm soapy water.
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.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
The AdBlue® is contained in
a special tank holding about
17 litres.
Leather
Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Its capacity allows a driving range of
approximately 5,600 miles (9,000 km), highly
dependent on your driving style.
An alert system is triggered automatically once
the reserve level is reached: you can then drive
for a further 1,500 miles (2,400 km) before the
tank is empty.
Refer to your vehicle's Maintenance and
Warranty guide for information on all the
special precautions to observe.
