Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.

dealer or a qualified workshop.
-
B
elow mark B
, then top up the engine oil
immediately.
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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health,
and may be very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers
reser ved for this purpose at a
CITROËN
dealer or a
qualified workshop.
Engine oil
The level is checked either using the
oil level indicator in the instrument
panel when the ignition is switched
on, for vehicles equipped with an
electric gauge, or using the dipstick.
The vehicle must be parked on a level sur face,
w ith the engine stopped for more than 30 minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). It is recommended
that you check the level, and top up if
necessary, every 3,000
miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Practical information

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.
Cabin filter
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessar y .A clogged cabin filter may have an
adverse effect on the per formance of
the air conditioning system and generate
undesirable odours.

engine oil is changed.
Particle filter (Diesel)
or 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.
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.
AdBlue (BlueHDi)
An alert is triggered once the reser ve 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.
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.
Other wise, have them 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
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
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 any work on the 12 V batter y,
refer to the corresponding section.
Practical information

193
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
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.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is per fectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic 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.
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
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.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
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
j o u r n ey.
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.

194
Headlamps and lamps
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.
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a
sponge
and warm soapy water.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty guide for information on all the
special precautions to observe.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance 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.
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.
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 reser ve level is reached: you can then drive
for a

further 1,500

miles (2,400 km) before the
tank is empty.
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!
Driving with worn or damaged tyres reduces
the braking and road holding per formance 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.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Practical information

195
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators , refer to the
corresponding sections.
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 travelling a
distance
of 685

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.
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
® fluid that meets the
ISO
22241
standard.
-

N

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

N

ever dilute AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN
d
ealer or a

qualified workshop.
You can also visit a

ser vice station equipped
with AdBlue
® pumps specially designed for
passenger vehicles.
Recommendations on
storage
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never keep bottles or containers of
AdBlue
® in your vehicle.
Precautions for use
AdBlue® is a urea-based solution. This liquid
is
non-flammable, colourless and odourless
(when kept in a
cool place).
In the event of contact with the skin, wash the
affected area with soap and water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15
minutes. If you feel
a

persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
AdBlue
® freezes below about -11°C and
deteriorates above 25°C. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.
