2023 CITROEN C3 AIRCROSS engine oil

131
Practical information
7supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►
Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Visit a CITROËN dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.

132
Practical information
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular 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.
Otherwise, 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.
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
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery with
special technology and specifications.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
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 .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting 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,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly 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, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.

Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
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.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
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. Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance 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.
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 3,900
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
