gearbox system,
- the electric parkin
g brake is being applied,
- some special conditions (battery charge,engine temperature, braking assistance,
ambient temperature...
) where the engine is
needed to assure control of a system.

The system is reactivated automaticallyat every new star t using the key.
Reactivation

This system requires a specific battery with aspecial specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the system. In the event of a malfunction with the s
ystem,
the "ECO OFF"switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.


Operating fault
Maintenance

Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.

The Stop & Star t system makes use of advanced technology. All work on this type of battery must be done only by a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and the
display of a message.
In the event of a fault in STOP mode, thevehicle may stall. All of the instrumentpanel warning lamps come on.Depending on version, an alert message may also be displayed askingyou to put the gear lever into position Nand put your foot on the brake pedal.
It is then necessary to switch off the ignition, then restart the engine using the key.

271Practical information














12 V battery
Procedure for starting the engine using another battery or for charging your flat battery.
The battery is located under the bonnet.
For access to the (+) terminal:
) Release the bonnet using the interior lever,
then the exterior safety catch, ) raise the bonnet and secure it with its stay, )
lift the plastic cover for access to the (+)
terminal.
Access to the battery

After refitting the battery, the Stop & Start system will only be active after acontinuous period of immobilisation of the vehicle, a period which depends on the climatic conditions and the state of charge of the battery (up to about 8 hours).
The presence of this label, in particular with the Stop & Star t system, indicatesthe use of a 12 V lead-acid battery withspecial technology and specification;
the involvement of a CITROËN dealer or a qualified workshop is essential when replacing or disconnecting the battery.

Check that the battery posts and terminals are clean. If they are coveredwith sulphate (white or green deposit), disconnect them and clean them.


Batteries contain harmful substancessuch as sulphuric acid and lead. Theymust be disposed of in accordancewith regulations and must not, in any circumstances, be discarded with household waste. Ta k e used cell batteries and vehiclebatteries to an authorised collection point.



Before doing any work
Immobilise the vehicle: apply theparking brake, put the gearbox inneutral *
, then switch off the ignition. Check that all electrical equipment is switched off.


*
or position Pfor an automatic gearbox.

273Practical information

Charging the battery using
a battery charger

If the battery of your vehicle is flat or prior
to taking the vehicle out of ser vice for an extended period, you can charge the battery
using a battery charger.
For information on the specification of batterychargers compatible with your battery, refer to
a CITROËN dealer or a qualified workshop.

The Stop & Start battery does not haveto be disconnected for charging.


Reinitialisation after
reconnection
After any reconnection of the battery, switch on
the ignition and wait at least one minute before
starting, to allow time for the initialisation of theelectronic systems.
By referring to the corresponding sections, you should set or initialise the following systems yourself:


- one-touch electric windows,

- time and date,

- audio and navigation system settings.

It is recommended that the battery be disconnected if the vehicle is not be used for more than a month.

Check that no aler t message or warning lamp comes on after switching on the ignition.
However, if minor problems persist after carrying out these operations, contact a CITROËN dealer or a qualified workshop.



Before disconnecting
)Go to the battery. )Check that all of the openings - doors, boot... - are closed but not locked.)Wait at least four minutes after switchingoff the ignition.
Charging
)
Disconnect the (+)terminal. )
Follow the instructions on use provided by
the manufacturer of the charger.) Connect the red cable of the charger to the (+) post of the battery, then the black cable
to the (-) terminal.) Once charging is complete, disconnect thecharger cables in reverse order.
The charging operation must be carried outin a well ventilated area and well away from naked flames and sources of sparks, so as to avoid any risk of explosion and fire. Do not try to charge a frozen battery; the
battery must first be thawed out to avoid any risk of explosion. If the battery hasfrozen, before charging, have it checkedby a CITROËN dealer or a qualified workshop, who will ensure that the internal components have not been damaged and that the casing is not cracked, which wouldintroduce the risk of a leak of toxic and corrosive acid.

Energy economy mode System which manages the period of use of cer tain functions to conser ve a sufficient level of charge in the battery.
After the engine has stopped, you can still use functions such as the audio equipment, windscreen
wipers, dipped beam headlamps, courtesy lamps, etc. for a maximum combined period of thirty
minutes.
This period may be greatly reduced if the battery is not fully charged.
A flat battery prevents the engine from
starting (refer to the corresponding paragraph).
If the telephone is being used at the same time on the navigation system, it will be interrupted after 10 minutes.


Switching to economy mode

Once this period has elapsed, a message
appears in the screen indicating that the vehiclehas switched to economy mode and the activefunctions are put on standby.

Exiting economy mode

These functions are reactivated automaticallythe next time the vehicle is driven. )In order to resume the use of these functions immediately, star t the engine and
let it run for a few minutes.
The time available to you will then be double
the period for which the engine is left running. However, this period will always be between
five and thir ty minutes.








Load reduction mode System which manages the use of certainfunctions according to the level of chargeremaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates cer tain functions, such as the air conditioning,
th
e heated rear screen...
The deactivated functions are reactivated automatically as soon as conditions permit.

QUESTIONANSWER SOLUTION
A telephone connects
automatically,
disconnecting another
telephone. Automatic connection overrides manual connection. Modify the telephone settings to remove automatic connection.

The Apple ®
player is®
not recognised whenconnecting to the USB port.
The Apple ®player is of a generation that is not compatible with the USB. Connect the Apple ®player to the AUX Jack socket using a suitable cable (not supplied).
Th
e hard disk or deviceis not recognised whenconnecting to the USBport. Some hard disks and devices need a power suppl
y greater than is
provided by the audio system. Connect the device to the 230 V socket, the 12 V socket or an external power supply.
Caution
:
ensure that the device does not transmit
a voltage greater than 5 V (risk of destruction of
the system).
When streamin
g, the sound cuts momentarily. Some telephones prioritise connection of the "hands-free" profi le. Delete the "hands-free" connection profi le toimprove streaming.

With the en
gine off, the
audio system switches off after a few minutes of use. When the en
gine is switched off, the audio system operating timedepends on the battery charge.
The switch-o
ff is normal: the audio system switches to economy mode and switches off to prevent discharging the vehicle's battery. Start the vehicle's en
gine to increase the batterycharge.
The messa
ge "the audio system is overheated"
appears on the display. In order to protect the installation if the surroundin
g temperature is too
high, the audio system switches to an automatic thermal protection mode leading to a reduction of the volume or stopping of the playing of the CD. Switch the audio s
ystem off for a few minutes to
allow the system to cool.
