Coolant level
The coolant level should be between
the two marks.When the engine is warm, the temperature of
the coolant is regulated by the fan.
As the cooling system is pressurised when the
engine is warm, wait at least one hour after
switching off the engine before carrying out
any
work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.Fluid specification
The coolant must conform to the
manufacturer's recommendations.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might become caught by the
fan blades. To ensure that this measurement is reliable, the
vehicle must be parked on level ground with the
engine cold.

fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.

the display of this message.
Fluid specification
For optimum cleaning, this fluid must not be
topped up with or replaced with plain water.

Checking components
12 V battery
Electrolyte level
For access to the 12 V Battery, refer
to the corresponding section. Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once a
month.
When carrying out work on the 12 V
Battery,
refer to the corresponding section for
details of the precautions to be taken before
disconnecting the battery and following its
reconnection.
Unless other wise 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.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them 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.

Manual gearbox
For servicing of the gearbox, refer to
the manufacturer's service schedule
for details of the interval for checking
this component.
"CVT" gearbox
For servicing of the "CVT" gearbox,
refer to the manufacturer's service
schedule for details of the interval for
checking this component.
Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp, accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine, the minimum speed is 37 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels
and the Diesel additive level in
particular, 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.

a battery charger
Follow the instructions for use provided
by the manufacturer of the charger.
Never invert the polarities.
Never start the engine by connecting a
battery charger.
Never use a battery booster of 24 V or
higher.
Check first that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not touch.
Switch off all power-consuming
equipment on the two vehicles (audio
system, wipers, lamps, etc.).
Ensure that the slave cables do not
pass near the moving parts of the
engine (fan, belt, etc.).
Do not disconnect the (+) terminal while
the engine is running.

In the event of a breakdown

214
C4-Aircross_en_Chap08_En-cas-de-panne_ed01-2016
Do not invert the polarities and use only a 12 V charger.
Do not disconnect the terminals while the engine is running.
Do not charge the batteries without disconnecting the terminals first.
Do not push the vehicle to start the engine if it is fitted with a CVT gearbox.
Disconnecting the battery
To maintain a sufficient level of charge
to start the engine, it is advisable to
disconnect the battery if the vehicle is not
going to be used for a very long period.
Before disconnecting the battery:
F
C
lose all the doors and windows,
the
tailgate and the roof.
F

S
witch off all power-consuming
equipment (audio system, wipers,
lamps, etc.).
F

S
witch off the ignition and wait
4
m

inutes.
Once you have gained access to
the
battery, start by disconnecting
the (-) terminal.
Following reconnection of the
battery
Following reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to permit initialisation of the
electronic systems.
However, if problems remain following this
operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you
must reinitialise certain equipment yourself,
such as:
-

T
he remote control key or the electronic
key (depending on version).
-

T
he electric blind(s).
-

T
he electric windows.
-

T
he date and time.
-

T
he stored radio stations. Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Never try to charge a frozen battery.
If the battery has been frozen, have
it checked by a CITROËN dealer or a
qualified workshop, who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous
period of immobilisation of the vehicle,
a period which depends on the exterior
temperature and the state of charge of
the battery (up to about 8 hours).
