After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping up.

spills on engine components (risk of fire).
F

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

A
dd more oil if necessary.
F

A
fter checking the level, carefully refit the
oil filler cap and the dipstick in its tube.
Engine oil change
Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil. 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.

Coolant level
Check the coolant level regularly.
It is normal to top up this fluid
between services.
When the engine is hot, the temperature of the
coolant is regulated by the fan. The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a risk of serious
damage to your engine.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
Screenwash fluid level
Top up the level when necessary.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades. When the engine is hot, as the cooling system is
pressurised, wait at least one hour after switching
off the engine before carrying out any work.
To avoid the risk of scalding in the event of an
urgent need to top up, with a cloth around the
cap, unscrew it by two turns to allow the pressure
to drop.
Once the pressure has dropped, remove the cap
and top up the level.
To ensure that the measurement is reliable, the
vehicle must be parked on level ground and the
engine must be cold.

Checking components
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.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
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.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.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the fixed
illumination of this warning lamp
accompanied by a warning message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
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.
For more information and the precautions to
take before starting work on the 12 V batter y
,
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.

checking the use-by date , read carefully
the instructions on use on the label before
pouring the contents of the bottle into your
vehicle's AdBlue
® tank.
Important : if your vehicle's AdBlue
®
tank is completely empty

- which is
confirmed by the alert messages and
the impossibility of starting the engine
-
you must add at least 4 litres and no
more than 10 litres. If any fluid is spilt or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the fluid has crystallised, clean it off
using a sponge and hot water.
Important:
when topping up after
running out of AdBlue , signalled
by the message " To p up AdBlue:
starting impossible ", you must wait for
about 5 minutes before switching the
ignition on again, without opening the
driver's door, unlocking the vehicle,
introducing the remote control key
into the ignition switch, or placing
the Keyless Entr y and Star ting
electronic key inside the vehicle.
Switch on the ignition, then wait for
10 seconds before starting the engine.

Audio and Telematics
QUESTIONANSWERSOLUTION
There is a difference in sound quality between the different audio sources.
For optimum sound quality, the audio settings can be adapted to the different sound sources, which may result in audible differences when changing source.
Check that the audio settings are adapted to the sources listened to. Adjust Balance, Treble, Bass to the middle position, select the "None" musical ambience and set the loudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.
With the engine off, the system switches off after a few minutes of use.
When the engine is switched off, the system's operating time depends on the state of charge of the battery. The switch-off is normal: the system switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
The date and time cannot be set. Setting of the date and time is only available if the synchronisation with the satellites is deactivated. Settings menu / Options / Time-Date setting. Select the "Time" tab and deactivate the "GPS synchronisation" (UTC).
