Cause



Action/Observations








Battery charge


fi xed. The battery charging circuit
has a fault (dirty or loose
terminals, slack or cut
alternator belt, ...). The warning lamp should go off when the
engine is started.
If it does not go off, contact a CITROËN
dealer or a qualifi ed workshop.







Braking


fi xed, associated
with the STOP
warning lamp. The braking system fl uid level
has dropped signifi cantly. You must stop as soon as it is safe to do so.
Top up with brake fl uid recommended by
CITROËN.
If the problem persists, have the system
checked by a CITROËN dealer or a
qualifi ed workshop.

fi xed, associated
with the electric
parking brake
malfunction
warning lamp,
if the parking
brake is released. The braking system has a
fault. You must stop as soon as it is safe to do so.
Park, switch off the ignition and contact a
CITROËN dealer or a qualifi ed workshop.

+
fi xed, associated
with the STOP
and ABS warning
lamps. The electronic brake force
distribution (EBFD) system
has a fault. You must stop as soon as it is safe to do so.
Have it checked by a CITROËN dealer or
a qualifi ed workshop.

Cause



Action/Observations








Anti-lock
Braking
System (ABS)


fi xed. The anti-lock braking system
has a fault. The vehicle retains conventional braking.
Drive carefully at reduced speed and
contact a CITROËN dealer or a qualifi ed
workshop without delay.



Engine
autodiagnosis
system


fl ashing. The engine management
system has a fault. Risk of destruction of the catalytic converter.
Have it checked by a CITROËN dealer or a
qualifi ed workshop.

fi xed. The emission control system
has a fault. The warning lamp should go off when the
engine is started.
If it does not go off, contact a CITROËN
dealer or qualifi ed workshop without delay.





Low fuel level


fi xed,
accompanied
by and audible
signal and a
message. When it fi rst comes on there
remains approximately
6 litres
of fuel in the tank.
At this point, you begin to use
the fuel reserve. Refuel as soon as possible to avoid
running out of fuel.
Until suffi cient fuel is added, this warning
lamp will come on every time the ignition
is switched on, accompanied by an
audible signal and a message.
Depending on version, the audible
signal and message are repeated with
increasing frequency as the fuel level
drops towards "0"
.
Fuel tank capacity: approximately
60 litres
.
Never continue to drive until you run
out of fuel, as this could damage the
emission control and injection systems.

Operating fault


When the ignition is switched on, fi xed
illumination of the indicator lamp in the
button indicates a fault with the system.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.



Locking the vehicle with exterior
perimeter monitoring only
Deactivate the interior volumetric and
anti-tilt monitoring to avoid unwanted
triggering of the alarm in certain cases
such as:


- leaving a pet in the vehicle,

- leaving a window partially open,

- washing your vehicle,

- changing a wheel,

- having your vehicle towed,

- transport by sea.

Deactivation of the interior
volumetric and anti-tilt monitoring


)
Switch off the ignition.

)
Within ten seconds, press the but-
ton until the indicator lamp is on
continuously.

)
Get out of the vehicle.

)
Press the locking button on the re-
mote control immediately. The exterior perimeter monitoring alone
is activated: the indicator lamp in the
button fl ashes once per second.
To be effective, this deactivation
must be carried out each time
the ignition is switched off.

Reactivation of the interior
volumetric and anti-tilt monitoring


)
Press the unlocking button on the
remote control to deactivate the ex-
terior perimeter monitoring.

)
Press the locking button on the re-
mote control to activate all the moni-
toring functions.
The indicator lamp in the button again
fl ashes once per second.



Triggering of the alarm


This is indicated by sounding of the si-
ren and fl ashing of the direction indica-
tors for thirty seconds.
The monitoring functions remain active
until the alarm has been triggered elev-
en times in succession.
When the vehicle is unlocked using the
remote control, rapid fl ashing of the in-
dicator lamp in the button informs you
that the alarm was triggered during your
absence. When the ignition is switched
on, this fl ashing stops immediately.



Failure of the remote control

To deactivate the monitoring functions:



)
unlock the vehicle using the key in
the driver's door lock,

)
open the door; the alarm is trig-
gered,

)
switch on the ignition; the alarm
stops; the indicator lamp in the but-
ton goes off.




Locking the vehicle without
activating the alarm



)
Lock or deadlock the vehicle using
the key in the driver's door lock.

BRAKING ASSISTANCE
SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:


- anti-lock braking system (ABS),

- electronic brake force distribution
(EBFD),

- emergency braking assistance (EBA).

When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.



Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.

Activation
The anti-lock braking system comes
into operation automatically when there
is a risk of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
Operating fault
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunc-
tion of the anti-lock braking system
which could result in loss of control of
the vehicle when braking.
If this warning lamp comes on,
together with the STOP
and
ABS
warning lamps, accompa-
nied by an audible signal and
a message in the screen, it indicates a
malfunction of the electronic brake force
distribution which could result in loss of
control of the vehicle when braking.

You must stop as soon as it is safe
to do so.











Emergency braking assistance

System which, in an emergency, en-
ables you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.

Activation
It is triggered by the speed at which the
brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase
in braking effi ciency.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.

FREQUENTLY ASKED QUESTIONS



QUESTION



ANSWER



SOLUTION


Playing of streaming fi les
does not start. The peripheral device connected does not support automatic play. Start the playback from the device.
The names of tracks and
the track length are not
displayed on the screen
when streaming audio. The Bluetooth profi le does not allow the transfer of this information.
The quality of reception of
the radio station listened
to gradually deteriorates
or the stored stations do
not function (no sound,
87.5 Mhz is displayed...). The vehicle is too far from the transmitter used by the station listened
to or there is no transmitter in the geographical area through which the
vehicle is travelling. Activate the "RDS" function by means of the
short-cut menu to enable the system to check
whether there is a more powerful transmitter in
the geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block
reception, including in RDS mode. This phenomenon is normal and does not
indicate a fault with the audio system.
The aerial is absent or has been damaged (for example when going
through a car wash or into an underground car park). Have the aerial checked by a CITROËN dealer.
I cannot fi nd some radio
stations in the list of
stations received. The station is not received or its name has changed in the list.
Some radio stations send other information in place of their name (the
title of the song for example).
The system interprets this information as the name of the station. The name of the radio
station changes.
