Disconnecting the cables
After refitting the battery, the Stop & Start system will only be active after a continuous 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 par ticular with the Stop & Star t system, indicates the use of a 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. Failure to obser ve this recommendation
may cause premature wear of the battery.
Reconnecting the cables
 Position the open clip 1 of the cable on the positive terminal (+) of the battery.  Press ver tically on the clip 1 to position it correctly against the battery.  Lock the clip by lowering the tab 2 .
Do not force the tab as locking will not be possible if the clip is not positioned correctly; star t the procedure again.

 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 .  Connect the other end of the green or black cable to the ear th point C on the broken down vehicle.
 Operate the star ter, let the engine run.  Wait until the engine returns to idle and disconnect the cables.
Charging the battery using
a battery charger
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.
 Disconnect the battery from the vehicle.  Follow the instructions for use provided by the manufacturer of the charger. Reconnect 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.
The Stop & Star t battery does not have to be disconnected for charging.
It is advisable to disconnect the battery if the vehicle is to be left unused for
more than one month.

battery

265Practical information
Load reduction mode
System which manages the use of cer tain functions according to the level of charge remaining in the battery. When the vehicle is being driven, the load reduction function temporarily deactivates cer tain functions, such as the air conditioning,
the heated rear screen... The deactivated functions are reactivated automatically as soon as conditions permit.
Do not disconnect the terminals while the engine is running. Do not charge the batteries without disconnecting the terminals first. Do not push the vehicle to star t the engine if it is fitted with the 6 -speed electronic gearbox system.
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 star ting to permit initialisation of the electronic systems. However, if problems are encountered following this operation, contact a CITROËN dealer or a qualified workshop. Referring to the corresponding section, you must yourself reinitialise: - the remote control key, - the GPS satellite navigation system.

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 func tions such as the audio equipment, windscreen wipers, dipped beam headlamps, cour tesy lamps, etc. for a maximum combined period of thir ty minutes.
This period may be greatly reduced if the battery is not fully charged.
A flat battery prevents the engine from star ting (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 vehicle has switched to economy mode and the active functions are put on standby.
Exiting economy mode
These functions are reactivated automatically
the 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.
