12 V battery
The presence of this label indicates the use of a 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer or qualified workshop is required when replacing or disconnecting the battery. Failure to observe this recommendation may cause premature wear of the battery.
The battery is located under the bonnet. To gain access to it:  open the bonnet using the interior release lever, then the exterior safety catch,  remove the plastic cover on the (+)
terminal,  if necessary, unclip the fusebox to remove the battery.
Access to the battery
 Raise the locking tab D fully to release the cable terminal clamp E .
Reconnecting the (+) cable
 Position the open clamp E of the cable on the positive post (+) of the battery.  Press vertically on the clamp E to position it correctly on the battery.  Lock the clamp by spreading the positioning lug and then lowering the tab D .
Do not apply excessive force on the tab as locking will not be possible if the clamp is not positioned correctly; start the procedure again.
Before doing any work on your vehicle, switch off the ignition ( Ready lamp off) to avoid any risk of injury resulting from automatic operation of the engine.
Your vehicle is fitted with a conventional 12 V battery, located under the bonnet, in addition to the high voltage battery used by the hybrid system. In certain conditions, if the 12 V battery is too discharged to activate the hybrid system, recharging from another conventional 12 V battery is possible. Do not carry out this recharge if the Readylamp is on.
Procedure for starting the engine using another battery or charging a discharged battery.
Disconnecting the (+) cable

239Practical information
DS5-HYBRID_EN_CHAP08_INFO PRATIQUES_ED02-2013
After refitting the battery, the Stop & Start system will only be active after several hours depending on the climatic conditions and the state of charge of the battery (up to about 8 hours).
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.
Starting using another
battery
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. Do not try to start the engine by connecting a battery charger. Do not disconnect the (+) terminal when the engine is running.
 Remove the plastic cover from the (+) terminal, if your vehicle has one.  Connect the red cable to the positive terminal (+) of the flat battery A , then to the positive terminal (+) of the slave battery B .  Connect one end of the green or black cable to the negative terminal (-) of the slave battery B (or earth point on the other vehicle).  Connect the other end of the green or black cable to the earth point C on the broken down vehicle (or on the engine mounting).  Start the engine of the vehicle with the good battery and leave it running for a few minutes.
 Operate the starter on the broken down vehicle and let the engine run If the engine does not start straight away, switch off the ignition and wait a few moments before trying again.  Wait until the engine returns to idle then disconnect the jump lead cables in the reverse order.  Refit the plastic cover to the (+) terminal, if your vehicle has one.
 Disconnect the battery from the vehicle.  Follow the instructions for use provided by the manufacturer of the charger.  Connect the battery starting with the negative terminal (-).  Check that the terminals and connectors are clean. If they are covered with sulphate (whitish or greenish deposit), remove them and clean them.
Charging the battery using
a battery charger

DS5-HYBRID_EN_CHAP08_INFO PRATIQUES_ED02-2013
Do not attempt to charge the high
voltage battery.
The batteries contain harmful substances such as sulphuric acid and lead. They must be disposed of in accordance with regulations and must not, in any circumstances, be discarded with household waste. Take used remote control batteries and vehicle batteries to a special collection point.
It is advisable to disconnect the battery
if the vehicle is to be left unused for more than one month.
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. Do not try to charge a frozen battery; the battery must first be thawed out to avoid the risk of explosion. If the battery has been frozen, before charging 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. Do not reverse the polarity 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. Wash your hands after wards.
Do not push the vehicle to start the engine if the vehicle is fitted with the electronic gearbox.
Before disconnecting the battery
Wait 2 minutes after switching off the ignition before disconnecting the battery. Close the windows and the doors before disconnecting the battery.
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 yourself reinitialise (depending on version): - the remote control key, - the electric blind(s), - ...
Do not push the vehicle to start the engine.
Some functions are not available if the battery is not sufficiently charged.

DS5-HYBRID_EN_CHAP08_INFO PRATIQUES_ED02-2013
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.
Energy economy mode
Switching to economy mode
A message then 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: - for less than ten minutes, to use the equipment for approximately five minutes, - for more than ten minutes, to use the equipment for up to approximately thirty minutes. 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 (refer to the "Battery" section).
In this energy economy mode and when starting up the hybrid system, it may take a few seconds before the Readylamp comes on.
Load reduction mode
System which manages the use of certain functions according to the level of charge remaining in the battery. When the vehicle is being driven, the load reduction function temporarily deactivates certain functions, such as the air conditioning, the heated rear screen... The deactivated functions are reactivated automatically as soon as conditions permit.

Checks
Unless otherwise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine. Other wise, have them checked by a CITROËN dealer or a qualified workshop.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
The presence of this label, in particular with the Stop & Start system, indicates the use of a specific 12 V lead-acid battery with special technology and specification. The involvement of a CITROËN dealer or a qualified workshop is essential when replacing or disconnecting the battery.
12 V battery
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter.
When carrying out work on the battery, refer to the "12 V battery" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
