Operating fault
In the event of a malfunction with the system,
the "ECO OFF" switch warning lamp flashes
for a few seconds, then comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.In the event of a fault in STOP
mode, the vehicle may stall. All of
the instrument panel warning lamps
come
on.
Depending on version, an alert
message may also be displayed
asking you to put the gear selector into
position

N and to put your foot on the
brake pedal.
It is then necessary to switch off the
ignition, then restart the engine using
the key.
The Stop & Start requires the use of a
12 V battery of special technology and
characteristics.
All work on this type of battery must
only be carried out by a CITROËN
dealer or a qualified workshop.

1st turn rear wards: rear foglamps off.
-

2nd turn rear wards: front foglamps off.
Front and rear foglamps
In good or rainy weather, both day and
night, use of the front and rear foglamps
is prohibited. In these situations, the
power of their beams may dazzle other
drivers. They should only be used in fog
or falling snow.
In these weather conditions, it is your
responsibility to switch on the foglamps
and dipped headlamps manually as the
sunshine sensor may detect sufficient
light.
Do not forget to switch off the front and
rear foglamps when they are no longer
needed.Switching off the lighting when
switching off the ignition
When the ignition is switched off, all of the
lamps switch off immediately, except for
the dipped beam headlamps if automatic
guide-me-home lighting is activated.
Switching on the lighting
after switching off the
ignition
To reactivate the lighting control stalk,
turn the ring A to position "0" - lighting
off, then to the position of your choice.
When the driver's door is opened, a
temporary audible signal warns you that
the vehicle's lighting is on.
They switch off automatically after a
period which depends on the state of
charge of the battery (entry to energy
economy mode).

Energy economy mode
System which manages the duration of use of
certain functions to conserve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system, windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.Switching to economy mode
A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.
If a telephone call is being made at this
time, it will be maintained for around
10
minutes with the Bluetooth
® hands-
free system of your audio system.
Exiting economy mode
These functions are reactivated automatically
next time the vehicle is driven.
In order to restore the use of these functions
immediately, start the engine and let it run:
-

f
or less than ten minutes, to use the
equipment for approximately five minutes,
-

f
or more than ten minutes, to use the
equipment for up to approximately
thirty
m

inutes.
Let the engine run for the duration specified to
ensure that the battery charge is sufficient.
Do not repeatedly and continuously restart the
engine in order to charge the battery.
A flat battery prevents the engine from
starting.

Checks
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.
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.
Air filter and passenger compartment filter
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. Replace the oil filter each time the
engine oil is changed.
Oil filter
Refer to the manufacturer's service schedule
for details of the replacement interval for this
component.
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
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.

Access to the battery
The battery is located under the bonnet.
For access to the (+) terminal:
F
r
elease the bonnet using the interior lever,
then the exterior safety catch,
F

r
aise the bonnet and secure it with its stay.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or fire.
Wash your hands after wards.
If your vehicle has an automatic
gearbox, do not try to start the engine
by pushing the vehicle.

Starting using another battery
When your vehicle's battery is discharged, the
engine can be started using a slave battery
(external or on another vehicle) and jump lead
cables or a battery booster.F

f the engine does not start straight away,
switch off the ignition and wait a few
moments before trying again.
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery
b o o s t e r.
First check 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 be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, ...).
Ensure that the jump lead cables do
not pass close to moving parts of the
engine (cooling fan, belts, ...).
Do not disconnect the (+) terminal when
the engine is running. Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.

Charging the battery using a battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances it may be necessary to
charge the battery:
-
i
f you use your vehicle essentially for short
journeys,
-

i
f the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
If you envisage charging your vehicle's
battery yourself, use only a charger
compatible with lead-acid batteries of a
nominal voltage of 12 V.
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.
It is not necessary to disconnect the
battery. Follow the instructions for use provided
by the manufacturer of the charger.
Never reverse polarities.
If this label is present, it is essential
to use only a 12 V charger, to avoid
causing irreversible damage to the
electrical components related to the
Stop & Start system. F

Disconnecting the battery
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of service for a long
period.
Before disconnecting the battery:
F

c
lose all openings (doors, boot, windows),
F

s
witch off all electrical consumers (audio
system, wipers, lighting, ...),
F

Having exposed the battery, it is only
necessary to disconnect the (+) terminal.Following reconnection of the
battery
After reconnecting the battery, switch on the
ignition and wait 1 minute before starting the
engine to allow initialisation of the electronic
systems.
However, if minor problems persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you
must yourself reinitialise or reset certain
systems, such as:
-

t
he remote control,
-

t
he electric windows,
-

t
he panoramic sunroof blind,
-

t
he date and time in the audio system,
-

t
he radio preset stations.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 ambient
temperature and the state of charge of
the battery (up to about 8 hours).
