CITROEN C3 AIRCROSS 2020 Owners Manual

For more information on the precautions
to take before starting work on the 12 V
battery , 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
Replace 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.
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 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).

Practical information

180
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN 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.
Checking this system must be done 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.
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.
AdBlue® (BlueHDi
engines)
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the oxides of nitrogen (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a special tank holding about
15


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 emptied completely.
Practical information

181
During each scheduled ser vice 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 ser vices is greater than around
12,000

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 a running distance of
680

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.
For more information on the Warning
and indicator lamps and the associated
alerts, refer to the corresponding section. Freezing of 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 all weather conditions.
Topping up with AdBlue®
Before topping up, please read the
following warnings carefully.
Precautions for use
The AdBlue® solution is based on urea. 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. Keep AdBlue
® out of the reach of children,
in its original container.
Never transfer AdBlue
® to another
container: it would become contaminated.
Use only AdBlue
® fluid that meets the
ISO
22241 standard.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
Containers are available from a
CITROËN

dealer or a qualified workshop.
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).
You can also visit a ser vice station
equipped with AdBlue pumps specially
designed for private vehicles and light
goods vehicles.

Practical information

182
Recommendations on storage
AdBlue® freezes at 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.
If the fluid has frozen, it can be used once
it has completely thawed out at ambient
temperature.
Never keep AdBlue
® containers in your
vehicle.
Procedure
In cold weather, before per forming the top-up,
ensure that the temperature is above -11°C.
Otherwise the AdBlue
® may be frozen and so
cannot be poured into the tank.
Park your vehicle in a warmer area for a few
hours to allow the top-up to be carried out. F

Temporary puncture
repair kit
Scan the QR code on page 3 to view
explanatory videos.Comprising a compressor and a sealant
cartridge, it allows the temporary repair
of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
Only the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
Under-inflation detection
After repair of the tyre, the warning
lamp will remain on until the system is
reinitialised.

detection , refer to the corresponding
section.

the boot floor.
List of tools
1. Temporary puncture repair kit.
Contains a sealant cartridge for the
temporary repair of a tyre and can also be
used for adjusting tyre pressures.
2. Socket for the security bolts (located in the
glove box or in the tool box) (depending on
ve r s i o n).
For adapting the wheelbrace to the special
"security" bolts.
3. Removable towing eye.
4. Flat blade screwdriver.
Allows the cover plate on the front or
rear bumper to be opened to screw in the
removable towing eye 3.
For more information on Towing the vehicle
and using the removable towing eye, refer to
the corresponding section.
Composition of the kit
1. 12 V compressor, with built-in pressure
gauge.
2. Bottle of sealant, with built-in hose.
3. Speed limit sticker.
The speed limit sticker must be secured
to the interior of the vehicle in the driver's
field of vision, to remind you that a wheel
is in temporary use.
Do not exceed a speed of 50
mph
(80
km/h) when driving with a tyre repaired
using this type of kit.
